WIRELESS NOT WORKING - Lenovo 3000 C200 Notebook

Wireless router works if wired won't work wireless

Yes even without any NIC card installed on your computer , the wireless adapter will definitely work since its a different device that work for wireless connection and has nothing to do with your NIC card configuration.

The wireless router needs the wireless settings configured eg. the SSID, encryption etc and then the wireless card in the computer/laptop needs to be configured with the router's wireless settings. Please click on this link and follow my instructions to secure your wireless network :-

The wireless card is configured for your D-Link at home.
You need to configure your laptop's wireless card for the wireless settings at work too (ie the SSID and encryption etc.). Contact the network manager at your work for the wireless configuration so you can configure the wireless card with these settings.
It maybe possible to setup different profiles on the laptop's wireless card, one for home and one for work so you can just click on the correct profile depending on your home or work location.

First of all,check the DHCP option in wireless router.If its enable then go to remote user whether PC or laptop enable the DHCP option.

Defaultly laptop have wireless adapter.But IN system doesnot have.SO you need to buy a new wireless adapter..

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.

few things you can try:
1. check to make sure you're getting an IP address.
2. try reloading the wireless card driver.
3. is you wireless static or dynamic? If dynamic, try configuring it with static setting.
4. If this don't work, try the wireless card on a different slot.
5. if don't work, try on a different PC to see if wireless card is working or not.
It's possible you have a bad wireless card.
good luck!!

My Dell wireless keyboard doesn't work. I replaced the batteries in it and pressed the green button on the back of it then the button on the wireless thing plugged into the computer. That light blinks for a few seconds then stops but the keyboard still doesn't work. My wireless mouse works fine.

1. Make sure that wireless settings are properly synchronized.
>> ssid/security key.
2. Check your computers wireless connection status
> Make sure that it is set to "obtain ip address automatically)
3. If still not working if computer is set to obtain ip automatically, try assigning static ip on wireless pc
> You need to know your router's ip address and dns
4. Disable firewall on wireless pc.
