I have an IBM think pad purchased used from a friend. I have a Net Gear wireless router and a PC card for the laptop. How can I boost the signal to receive it farther away. At 50 feet it is only 30 percent. A friend logged on with their computer in the same location and had a signal at 80 percent. I don't know what kind of wireless card they had since it was built in.

If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router. To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair. This will force the wireless router to issue a IP address to the wireless cardon the laptop.
Laptops have an internal wireless antenna that receives the signal from the wireless router/access point. The performance of these wireless cards varies widely from manufacturer to manufacturer and sometimes even from model to model in the same brand. Issues effecting reception are distance between laptop to router, obstructions (many commercial buildings use metal studs which can significantly reduce signal strength), electrical interferance and other things.
While there's not really any way to boost the reception of the wireless card in your laptop, you CAN purchase what are called 'hi-gain' wireless cards from various manufacturers such as Netgear, Linksys, and many others. These so called hi gain antennas can pick up a signal from as far away as 1/4 mile in some cases. If you can't figure out what's causing the problem with your laptops' wireless card, purchasing one of these cards might be a good solution for you.
Best of luck! Hope this helps!
Check in the device manager if your computer is seeing the wireless card driver.
Right click my computer, properties, hardware, device manager,network adapters.
Is the wireless card listed?
If it is right click uninstall and reboot on reboot the wireless card should be seen as new hardware follow the wizard and let it install the driver.
If the computer is seeing the card but it has a yellow mark next to it the driver is not loaded you need to get the appropriate driver for that type of card from it's support site or once again try the uninstall reboot.
That’s the wireless card.
Is the net-gear showing an internet connection.
Put a cat 5 cable from your laptop to the net-gear and try to connect via cable if that works it's got to be the wireless card driver or the wireless settings in the net-gear however if they worked previously there is no reason to suspect the router settings.
Hope this helps
FIRST POSSIBLE SOLUTION: Determine which version of IE you have installed. To do so, click "Help" on the IE toolbar and then click "About Internet Explorer." The version will appear in a dialog box. Go to the Microsoft website and upgrade to IE version 7 if you are using an earlier version. By upgrading, you may be able to resolve your IE problems. Repair damaged files automatically using IE 7's "Reset" feature. Go to the "Tools" menu and click "Internet Options." Click on the "Advanced" tab. Click the "Reset" button. Close all other programs if asked, and then click "Reset" to confirm that you want to reset IE and repair the files. Use XP's System File Checker to resolve IE problems. Click "Start" and then "Run." In the "Open" box, type "sfc /scannow" and click "Go." The System File Checker will scan your computer, finding and repairing damaged or missing files. Restart your computer after the process is finished. Update Windows XP to make sure you have the most recent service pack installed. Go to the Microsoft Windows, check for any available updates and install them. SECOND POSSIBLE SOLUTION: Make sure your computer is not too far away from your wireless router and you have a good signal. By placing your mouse pointer over the wireless connection icon, located in the bottom right corner of your taskbar, you can check to see if your signal strength is good. Anything less than a good signal can cause intermittent connections. SOLUTION: You will need to relocate your wireless router closer to your computer. If you have a 2.4 GHz wireless home phone, take notice if you lose the internet connection when placing or receiving a call. These wireless phones interfere with wireless routers because they both operate on 2.4GHz frequencies. If this happens you need to power down the router and then turn it back on. This will happen occasionally but not all of the time. SOLUTION: (1) upgrade your wireless phone to 5.8GHz, (2) use a corded phone or (3) use a wired internet connection to your router. If steps 1 and 2 did not solve your internet connection, borrow a friend?s laptop with a wireless card and see if their laptop can connect to the internet. Be sure to set your friends wireless connection settings to the same settings that your wireless card is set to. If your friend?s laptop connects to the internet then you may have a bad wireless card. Try reconfiguring your wireless card settings before going out to purchase an external wireless card. If your friend?s laptop can?t connect to the internet, try resetting the router to the factory defaults. Change the settings on the wireless card to the same settings as the factory default on the wireless router. If this works you are back in business. If it does not work for either computer, the wireless portion of your router is bad. SOLUTION: Purchase a new router or use a wired connection to one of your router ports.
The wireless configuration is set differently on routers, eg the SSID, and encryption. You need to configure the wireless LAN card in the laptop to connect/communicate with the different routers.
Some wireless LAN card allow you to setup different profiles/settings for different wireless routers. Eg one setting for the office and one for home, which allows easy connection to the Internet by selecting the appropriate profile/setting.
If you have been using this router/laptop for 3 years successfully and then all of a sudden it does not work, you may attempt to try an external USB wireless adapter. Does your T30 have 802.11b connectivity built in? It is not unusual for these to go out. Before you buy one check first to see if you can still access wirelessly at other hotspots? Or does the problem follow you around? If you can successfully connect at other hotspots then this is not the problem and it may very well be your router. Is there any way you can get a substitute rouer to test with before you purchace one? A friend maybe? It is probably one of these 2 issues. If you find your wireless is out on the laptop and you go to purchace a USB wireless adapter, go for a Linksys and make sure it is at least wireless "g" or "n" and not "b". And if you do not have enough USB ports then you may want the flat wireless card adapter that plugs in to the PCMCIA slot on the laptop. This can be Linksys also - I use this one (flat card) - "Wireless G Notebook adapter with SRX" Model Number WPC54GX. It is great and has speed boost. If your built in wireless on the laptop is bad, then any of these external adapters you choose to use will simply take over the wireless reception. Good Luck.
If I recall there are two types of wireless cards that are installed in the T40 series of laptops. Can't advise you which one is installed in your laptop. Download both of them and install one, it it doesn't work then install the other one.
Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows XP or Vista device drivers for your model laptop, You need to use a computer that has Internet access to download and transfer the files to your computer.
Once you get the wireless card operation, you need a wireless router that is connected to a cable or DSL modem which is connected to an Internet Service Provider.
You don't need a wireless router if you only want to connect to the Internet using wireless Hot Spots in public locations or Internet cafes.
