Dell X200 Keyboard Replacement

To contact us Click HERE
Well, the old Dell X200's keyboard gave up the ghost. Not entirely, but the good old backspace key stopped working, and it's really hard to use a keyboard without a backspace key.

Happily, it was easy to fix, as follows:
  1. Buy a replacement keyboard (I bought my "like new" replacement keyboard through eBay for about $20)
  2. Remove the battery
  3. Unscrew the six screws from the bottom of the Dell marked with a (K)
  4. Lever out the old keyboard from the bottom left. There is a little latch there.
  5. Before fully removing the keyboard, un-snap the ZIF ribbon connector
  6. Remove the keyboard completely
  7. Slide the new keyboard into place
  8. Push the keyboard cable into the ZIF connector; lock the ZIF connector
  9. Screw the keyboard back in place with the six screws
  10. Reinstall the battery
The end result? My 8 year old Dell X200 laptop is still running strong! It'd be awesome to get 3 more years out of it. Its only real limitation is it's limited RAM.

Fixing Wifi Problems: MacBook wireless card replacement

To contact us Click HERE
For years my cousin was suffering with the WIFI of his 2008-vintage MacBook. His MacBook would drop its WIFI connection every few hours (or minutes), and he'd have to manually stop and start the WIFI on his MacBook to fix it. The bad behavior made web surfing, Netflix, and anything else on-line quite unpleasant.

The Bad WIFI card, as pulled from my cousin's MacBook.
I tried everything to try to fix the problem. I replaced his router, tweaked OS settings, and even re-installed the OS. The on-line forums weren't particularly helpful - a lot of people had a lot of ideas how to fix it with software, but ultimately none of their suggestions worked.

So I concluded that the problem was with the MacBook's WIFI card.

Some of you might think that the MacBook has its WIFI chip soldered onto the MacBook's main board, but that's not the case - the classic MacBook uses a fairly common WIFI card. Getting access to that card isn't trivial, but if you're able to drive a dozen or so screws with care, it can be done.

I bought the replacement WIFI card on eBay. It was a standard Broadcom Mini PCI express 802.11a/b/g/n card with two antenna connections ... (a lot like this one at Amazon) and it was under $20.

I took the MacBook apart, based on the an on-line guide, removed the old WIFI card and put in the new one. I reassembled the MacBook.

We booted the MacBook, and everything came up fine. The new WIFI operates perfectly, and there were zero software changes that had to take place. No special drivers required, and performance and reliability has been better than ever. Interestingly, going into "About This Mac" feature of the Finder shows that the WIFI card type was a "Third Party" card instead of an "Airport Extreme".

If your MacBook's WIFI is persistently problematic, I suggest you think about having your WIFI card replaced.

802.11b WIFI is DEAD

To contact us Click HERE
802.11b is now utterly obsolete and must now be disabled by all access points, routers, and clients.

802.11b first emerged in 1999 - a hot new standard that provided inexpensive networking over the air. But by January 2003, a newer, even faster standard became commonplace - 802.11g. And since then, an even faster and more efficient standard - 802.11n has been on the scene.

802.11b is inefficient, and it slows down 802.11g and 802.11n networking due to protocol limitations. And therefore, I proclaim that 802.11b must be immediately banned from the world. Doing so will speed access for everyone.

So log into your access points and disable the mixed modes that support 802.11b. Throw out your old 802.11b-only interface cards and routers. You, and 99.99% of the rest of the world will see much better performance, and you'll be convincing the 0.01% of the world - those with 802.11b clients - to upgrade.

Upgrades are very inexpensive: 802.11n USB client interfaces are available for under $15, and 802.11n routers can be had for less than $25. At this point, there is simply no reason to have 802.11b around.   While we're at it, we might as well push for the end of 802.11g too.






Connecting your MIDI keyboard to your Mac

To contact us Click HERE
MIDI and the Mac.  It's easy, fun, and inexpensive!

I enjoy fooling around with musical instruments, and so when Garageband originally came out several years ago, I was very excited to start using it with my cheap little Casio keyboard.

Initially it seemed expensive and complicated to get the right parts together to connect the Mac to my keyboard via MIDI. I didn't want to spend a ton of money in professional-class electronics. I wanted to fool around.

Happily, I discovered that it's inexpensive and easy.  If you know where to look, a Mac-compliant MIDI adapter can be purchased for under $10! That's right, for less than $10 I connected my Mac to my MIDI keyboard and by MIDI drum kit.

I bought an MIDI-to-USB interface, in particular, on like this USB MIDI Cable available through Amazon. It's a simple device that has on MIDI "in" and one MIDI "out" connector on one end, and a USB connector on the other.  It doesn't require a power adapter - it's just a magic converter that translates MIDI into USB.

The beauty of this interface is that it required no special drivers for my Mac at all. My Mac, running Lion (and Snow Leopard, and Tiger before that) automatically detected it. Awesome.

I connected the MIDI-in connector on the cable to the MIDI-out port on my keyboard. And then I plugged the USB plug into my Mac. Hookup was that simple.

MIDI "out" cable goes to MIDI "in" port, and vice-versa
From there, I fired up the Garage Band application and turned on the keyboard. In Garageband, I created a new "Piano Project".

I started by creating a new "Piano" project
Once the new project appeared within Garageband, notes on my keyboard were coming out of my Mac's speakers. If this doesn't work, you may want to double check your volume and make sure that the "in" and "out" MIDI cables are plugged into the "out" and "in" on your keyboard.

From there, I was able to double-click on the Piano icon within the "tracks" view in order to change the instrument of my key presses to something else, like a sax. Do so reveals the Software Instrument selector.

Double-clicking on the piano icon sets you change the instrument

The Software Instrument list is fun and amusing


Since we play musical instruments in the house quite often, I decided to connect the Mac to an amplifier. I used a basic 3.5mm jack plugged into the headphone port of the Mac. I connected this to a small guitar amp.

Connecting a small guitar amp to the Mac

It's a good idea to turn down the volume on the amp before plugging or unplugging your Mac from it.

Next Steps

My next step is to experiment more deeply with GarageBand and some of the add-on instrument packs. Some add-on packs for GarageBand include:
  • The shareware Boldt instrument packs.
  • The Apple JamPacks (such as Symphony Orchestra, Rhythm Section, World Music, and Voices)
  • The AMG ExpansionPack for GarageBand
That's my initial attempt to get started with MIDI on the Mac. It works great, but there is a lot more to try! Have fun!

Fixing Ye Olde iBook

To contact us Click HERE
Here I will talk about repairing and upgrading a 12-inch Apple iBook G4 laptop.

A great friend of mine had a 12-inch iBook laptop from 2005 - with a broken keyboard.  She asked me to help her shop for a new Mac to replace her old tried-but-true laptop.

Whenever anyone asks me for computer advice, I ask them what they want to do with a new computer.
She told me that she used her computer for basic email and surfing the web - she said the old iBook was great for many years, but that now, with a broken (and dirty and gross) keyboard, it was time to move on.

After thinking about it for 15 minutes with her, we concluded that the best approach was to fix her old laptop.  A little upgrade is a LOT easier than going out and buying a new machine, and then migrating 6 years of data and apps.  Also, the price is a lot less than a new machine.

We went on-line and bought two things:

  • A replacement iBook keyboard, for around $40, and
  • A 1 GB memory stick, for under $20.

The replacement iBook keyboard (bottom) and 1 GB upgrade (top, in envelope)
The components arrived in a few days.  Here was the basic procedure:

  1. backed up everything
  2. shut down and unplugged the iBook
  3. removed the battery
  4. popped off the keyboard (sliding two levers in the corner is all it takes!)
  5. popped in the new RAM, which is situated under the keyboard
  6. Unplugged the old keyboard, plugged the new one in and snapped it in place
  7. Reinstalled the battery.  Done!

In all, it took less than 10 minutes to upgrade the iBook.

Instead, she ended up with an incrementally faster computer at a very low cost and with very low stress.  She did not end up with a new, fast-as-lightning computer with a hole in her pocket.

I loved this upgrade because the cost, effort, and result couldn't be beat:
  • A very clean looking laptop with a working keyboard
  • A faster laptop, thanks to the additional memory
  • Her same programs and files, in same location - NO confusion!
And I had:
  • An easy 15 minute upgrade
  • No stress helping her buy a new computer
  • No heavy lifting moving the data to a new computer
  • No additional "support" calls

In short, these old iBooks are still useful little computers.  And with a little effort, you can keep them ticking for several more years to come.

The Repaired and Upgraded iBook: Looking great, running great!

The IP Address of a Router

To contact us Click HERE
A network router such that we use at home has a two IP addresses, one for internal (LAN) and one for the external Internet (WAN). How can you find the IP address of the router?


Internal LAN IP address is usually set to default. Linksys routers, for example, use 192.168.1.1 for their internal IP addresses. When to see the IP Address you can, you can do the following manner;

Click Start -> Run CommandType CMD, you will view the first brought CMD

Then type IPCONFIG



D-Link and Netgear routers typically use 192.168.0.1. Some U.S. Robotics routers use 192 168 123 254, and some SMC routers use 192.168.2.1. No matter the brand of router, the default internal IP address must still be determined. Administrators often have the option to change the IP address during router setup. In any case, however, the LAN IP address must be specified.
Address, the external WAN-IP of the router is set when the router is connected to the Internet service provider. This address can also be seen in the router administrative console. Or, WAN-IP address can be found by visiting the IP address of a web-based search services such as http://checkip.dyndns.org/ from any computer on your LAN.
Another way to identify the public IP address of the router, ie by executing the command ping or traceroute. From inside the home network, a command (DOS) "ping-r 1" will send a message through our router to be sent to the IP address to be displayed. For example, "ping-r 1 www.yahoo.com" would generate the following message is displayed at the command prompt:
Replay from 66.94.230.43: bytes = 32 time = 294ms TTL = 56Route: 209.179.21.76In this example, the IP address after "Route:" (209.179.21.76) in accordance with the router's WAN address.

Setting Belkin Router

To contact us Click HERE
Setting Belkin Router - The following are some things that MUST be set before you use the Belkin Router for the network of SAP.

LAN Settings (Setting the IP Address)

Unlike the D-Link AP brand that uses the default IP 192.168.0.50. Apparently the brand Belkin Router & AccessPoint using the default IP 192.168.2.1. So if you want to access the router settings menu, the PC that will access stations must use the range / group of the same IP, ie 192.168.2 .......

This default IP can be directly used, just a PC client that follows its course. But if it does not deign to use the default IP, then the user can change the LAN Settings from the menu. Settings through the browser with the address 192.168.2.1. Utility of the display Settup Belkin Router will appear in the display. If you do not use it to access INTERNET MODEM, then DO NOT NEED to install the driver CD from the Router. Settup utility menu can be accessed directly from the browser with the default IP. Admin password at the initial setting is empty.
REMEMBER, if using a router / access point is more than one, then each - each should be given a different IP address, such as sequential:
Belkin Router 1 = 192.168.2.1Belkin router 2 = 192.168.2.2Belkin Router 3 = 192.168.2.3Belkin Router 4 = 192.168.2.4, and so on If the dizziness / forgotten passwords to settup that has been done, press the RESET BUTTON on the router / AP for a few seconds. Then the router / AP will be back at factory default settings.
IP Pool Seeting: used to set the order of IP in the same network, the default is the beginning of 2 s / d 100. Then the PC in the same network must use the IP range of 2 s / d 100. This setting does not need to be changed is not a problem, except if the PC in the network more than 100 pieces, then the setting can be changed from 2 s / d 255, for example.Lease Time: Choose Forever, keeping the connection from PC to Router / Access Point forever, without the dashed like a network connection using a cable.

CHANNEL & SSID

Channel and SSID is the menu to give the naming of Router / AP. It's important to do, especially if using Router / AP is more than one. Defaulnya use belkin54g name. We can change, for example with the name SAP_DPRD_1, if there is another router that is used, can use the name SAP_DPRD_2, SAP_DPRD_3, and so on.

Channel: the number of PCs that can connect through the router / AP in question.Wireless Mode: Select 54G Auto, then the router / AP will automatically detect the connection of a PC that uses a type of 802.11g wireless card.


SECURITY

IMPORTANT that each router / AP is attached is given the password, not just the password to enter the setup menu its utility, but also the password to log into the network router / AP it.

Select WPA-PSK (No Server), then give the password below. At least 8 characters, it is advisable to use a combination of numbers and letters. If there is a USB / Card with adapters that do not support WPA-PSK, it can use other options, namely 128bitWEP or 64bitWEP. See the manual for more details. Protection BEST (BEST) dalah using WPA-PSK. See the book of the manual for more details.


After connection to the Router / AP is given the password, then any existing PC USB connection adapter will not fit directly into the network router.

By using a USB Belkin. Do the following:

  • Go to the Belkin USB adapter program contained on the monitor screen, or on the menu bar on the right existing under the windows.
  • Next will appear Belkin Wireless Monitor program. In the Current Profile field will be empty, because I have found no AP or Router is read in the USB Adapter.
  • There is also a symbol with a CROSS between image Laptop with Router.
  • Sign in to the Profile Settings tab menu.
  • Then press the Add button
  • Enter a profile name, the name may be different profuile by name Router / AP that in fact, but should equate it with the name of the Router / AP will be accessible though not dizzy, especially when using a Router / AP is more than one. In the example I still use a naming defauklt from Belkin Router, which is belkin54g.
  • Press Next, fill in the Network Name field with the name of Router / AP will be accessible.Choice Network Type = Access Point and Transfer Rate = Automatic.
  • Press Next. On the Authentication Mode options, choose WPA-PSK, according to the type of password that we give to the router settings above.
  • Select TKIP, and press Next.
  • Finally given a password in accordance with the password in the settings on the Router / AP, ie in our example using passwordketupatsayur. password is caseSensitive, so uppercase letters are not the same as the small.
  • Complete signature, then the profile that we make will be entered into the list of profile. The final step is to press the Connect and wait a few moments, then the PC will be connected to the Router / AP.

In the figure, was seen when the PC is connected to the Router / AP. Do the same on the next PC. Do not forget to give a different IP address on any other computer.


MAKE SURE the PC is connected to Roputer / AP. Use a small program IP Anggry to see a list of existing IP. If the IP address of PC that we set the IP Address and Router / AP is listed in the IP program Anggry, then the network setup is successful. Do the same on any other computer.

Better yet jiga tried it with 2 PC's, if the two PCs that can connect with each other through the router / AP, Wireless network setup is successful.

Press the MORE button to display the details of the connection belkin info.

= 192.168.1.1 is the IP address of Router / AP
= 192.168.1.9 is your IP address.

SETTING MARKS ON ADAPTER D-LINK
  • Do not use the settings from Windows (see red circle above)
  • Log into the Wireless Adapter settings menu of the program is concerned, from a group of D-Link menu.
  • Kilik SiteSurvey menu, press the Refresh button if no list of Router / AP is there.
  • If there is already a list of Router / AP is there, then display the menu Klika Connectuntuk passwords and so forth.
After the Connect button is pressed, the dialog menu will appear as below. In the Security Mode option, select WPA-PSK, and enter the password twice in the column underneath the existing password. Click the button if you want a typed unmask we fill visible, or vice versa.
If WPA-PSK password is correct, then click the Apply button.



After pressing the Apply button, then the PC will be able to begin to connect with the router / AP.


SYSTEM SETTING

In system settings, there will be a column to give a PASSWORD is used to enter the SETUP UTILITY. Give the password, so that not just anyone can change the settings on the Router / AP is already installed.

ROUTER RESTART menu, serves to restart the Router / AP if the router is experiencing performance problems. So do not pull power. Especially if the router is installed in place are difficult to reach, or above the ceiling.


USE AS ACCESS POINT

Belkin router apparently can double as a router at the same time can also be an AP.Without connection with MODEM, then the router just like the AP function, so it's no longer need to make it as AP. AP settings as necessary if you want to add a connection between the AP as we add HUB kalai more than one at a same network.

Note:

The menus of other works if the Belkin Router that serves as a connection to the Internet memalui Modem. So I have described here are the menus that are important to settup Belkin Router to the LAN only, or as an AP.

REMEMBER, do not need to install drivers Router. Simply set all the PCs with the same IP range, will be able to directly enter the Setup Utility by entering the address 192.168.2.1 (or use the IP router in accordance with the setting ever conducted)
If anyone missed, please read the manual of the router.

Network Connection
The network connection is an attempt to connect all network equipment in the computer network infrastructure. You must concentrate first on a local area network before you make a connection to a WAN network that connects all your remote sites into a network connection system - a computer network infrastructure. This does not mean you do not need to create a WAN design into the design of your network until all of your local area network network is formed, however, you kosentrasikan first until you can be sure that your LAN network connection system has been efficiently before making a connection to the WAN.
It would be a lot of work to be completed within this network connection and depending on how big the scale of your network design. Creating a network connection in a company where the office is composed of several remote sites over the limit even to geography, different network connections in the local area network that connects several buildings in an area company or maybe just in a small office space. You must have completed the design of your network including a computer system that will use this network infrastructure systems. The work of this network connection is complicated depending on how big the scale of your network, especially if you have to also design a network backup in case of disaster or in anticipation of problems in the network.
It is assumed that you have created your network design diagrams and some of the sites you like the picture of this church service, how do you make a network connection according to diagram these sites?

The server room where multiple servers are located, was in the building HRD. there are about 80 users in this building. I told some servers - why do not all servers are in one room and in the same building? This is about the safety standards of security best practices regarding the placement of servers (next article). There are still two more buildings to be connected in a network connection:
1. Building mining which is about 70 meters from the building HRD (there are about 80 users as well)
2. The workshop, which is below the valley which is more than 300 meters from the building HRD (there are about 50 users here)Total users in this network is 200 (80 in the HRD building in Mining + 80 + 40 at the Workshop), and not including a permanent IP address need for multiple servers; printers; Wireless Access Point; switch; as well as VoIP. You can use a private IP network 192.168.100.0/24 katakana (254 available IP addresses) for all users and devices in this network. For that you can use 4 pieces of 24 port switch in the cascade in both mining and HRD building with 100BaseT Ethernet standard. While at the workshop just 3 switches 24 ports in the cascade. Exception in the server room you need to switch Gigabit 12 ports if all your servers are equipped with Gigabit Ethernet, to transfer data very quickly and will feel useful if you use a single device Autoloader backups for backup of all data servers; exchange and your database, are routinely done at night.
Then how about the network connection between the building with the HRD Workshop? Because the location of this workshop is under the valley with a distance of more than 300 meters, you may not use a cable connection. Then you can take advantage of wireless technology that connects two or more points through the access point radio transmission medium with a frequency 2.4 GigaHz. You can get this kind of market products such as Cisco Aironet. You can build two towers is simple to put the antenna on top of the tower from the second antenna access point can see each other without a hitch. Wireless devices can transmit data up to 58 Mbps; enough for a link between this building with air transmission media. Please read the next article about wireless local area network.
Now how do you connect the network connection between the buildings in Mining and in HRD which is about 70 meters? This will depend on the constraints you face, if you should decide to pull underground cable then use a LAN cable Cat 5e outdoor UTP which is designed specifically for outdoor use and waterproof and support gigabit speed. However, for reasons of security and ease of maintenance then enter the UTP cable whose diameter is large enough it into an iron pipe or the like, and if necessary Make a special kind of drainage channels.
Why not just use a wireless network between two buildings is like between HRD and workshops? Indeed, with very practical wireless network once you do not have to bother-2 pulled an underground cable, but you know if the wireless until now the highest speednya about 300 Mbps (draft 802.11n standards), while between the two buildings that you need a reliable connection gigabit speeds as the backbone of two buildings. In the Mining Office also there are some servers and data mining applications, especially very large data and geological data should be centralized backup in the building of HRD. Not to mention control of blackspot if there are problems with your wireless, or radio frequency interference number of obstacles. While the workshops are the obstacles to building requires us to use a wireless radio network for inter-building must pass through the valley and does not allow pull the cable through the woods that even though only about 300 meters. Wireless networks are very reliable if the two tower antennas can see each other. And again at the workshop only requires connection to a computer clients only.To complete the network connection, you still need to think about network configuration and network setup for all devices in this network connection such as IP addresses to all client PCs; permanent IP for the server; switch; printer and so on.
What's next? All you have to consider is the documentation of all this work
