Re: wireless lan card
Your nic card could be on board and part of the board which doesn't come out. if so just make sure you have an extra PCI slot on your board and go to a computer place and buy one.
If there is a Walmart over there you can get one there for about $20 or more. Try to make sure that it will install the drivers with your operating system. Other wise if it doesn't come with a cd you may have to download from the net.
this should solve your problem.
you could buy a USB type also. Office supply stores around $40.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Try turning off the router for 30 secs, then power it up again.
Then try connecting a LAN cable from the computer to the router and see if you can connect to the Internet.
If you can connect to the Internet then -
With the LAN cable open a browser and type in the configuration URL and check the Wireless settings, then check and/or the wireless card settings (it should have the router's SSID and encryption settings etc.)
Also install the latest wireless card driver.
Then test the wireless and Internet connection. If this doesn't work -
Next connect the computer with a LAN cable to the cable or DSL modem to see if you can connect to the Internet.
If you cannot get an Internet connection with the LAN cable, contact your ISP and get them to test the connection to your modem.
If the modem and Internet is OK and you still cannot get a wireless connection then the problem could be a faulty wireless router.
I assume you are following my instructions.
Did you connect the LAN cable from the DSL or cable modem to the WAN or Internet port on the wireless router?
To test if the modem is working properly, connect the LAN cable from the modem to the LAN network card on a computer and see if you can access the Internet.
If if doesn't connect to the Internet, contact your ISP and they can check the connection to your modem to determine if it is working properly.
Check the Device Manager to see if the Wireless LAN device is working and enabled. If not reinstall the Wireless LAN driver.
If the Wireless LAN is OK and enabled then sometimes when you bootup the Wireless LAN card doesn't get an IP address from the wireless router. This usually has a red X on the wireless connection icon and sometime you get an error message "Limited or no connection".
To get the router to issue the wireless LAN card with a new IP address, righr click on the Wireless icon and click on Repair.
You can also power down the router wait 15secs and power up the router again then reboot the computer.
If it still doesn't work you could have a faulty wireless card, see it your friendly computer shop can test it for you.
go into the device manager and uninstall the wireless adapter. Then click scan for hardware changes and let windows resinstall it. It sounds like a corrupt driver. Before doing so make sure you didnt hit the wireless button that shuts off the connection on the computer. :)
check the ettings on the router have not been altered. the chance of 2 wireless cards failing in the same time, on different pcs is very small, more likely the settings that allow connection in the router, the item common to both, have been changed, reinstalling the router has no effect on user settings,
WEP, encryption, MAC controls are all possible suspects, if there has been any change
lock down the router,
many wireless networks are unsecured at the router so that any person driving past can access your router and alter it, default security settings should be changed the day you turn it on
You need to start from beginning.
Clear all temp internet files and run this programme
Start>Run ipconfig /flushdns and hit enter.
Get into the routers settings(probably 192.168.2.1) and ensure in the Lan settings that 'DHCP Server' is on and wireless is enabled.(you might need to be connected by RJ45 lan cable first)
If it's a 125mbps router change settings to 54mbps to try that speed first(especially as your wireless cards will be 54 mbps)
look in Mac address Filtering is off.
Look in the DHCP Client list and see if your pc's were allocated ip addresses, if so it should allow an internet connection.
Go to both your pc's wireless cards properties and under TCP/IP properties ensure obtain ip address automatically is checked.
Restart both pc's and the router, disconnect cable and try wirelessly
