Windows 7: IBM Thinkpad T40 won't connect with wireless card

IBM Thinkpad T40 won't connect with wireless card

I have an IBM Thinkpad T40 with Windows 7 Ultimate. I have all the updates from both Windows Update and Lenovo. Everything is working great except that I can't seem to get my wireless PC card to work still. It's a Trendnet TEW-421PC card. Windows found the driver for the card but it still doesn't work. I even downloaded the driver from Trendnet's website and installed it and it doesn't work. The "Activity" light blinks continuously and
Windows detects the card but I can't seem to get it to connect to the internet. I had Windows troubleshoot it and it says there is a problem but none of the solutions seem to help. I can connect to the internet with an ethernet cable but sometimes I like to connect wirelessly. Can anybody help? Thanks in advance.

Hello and Welcome to SF,

Have you tried taking out the card then plug it back in again?

Are you using any wireless software for your Wi-Fi card?

Pls post an ipconfig /all for analysis.
See this link for more troubleshooting guide and instruction on how to post your ipconfig /all.
Win 7 Does not DETECT a working Net connection!!!

An update will be appreciated.

2XG,

Thanks for replying. I have tried taking it out & putting it back in & I still get the same result: the activity light just blinks continuously. I've installed Trendnet's Wireless Configuration Utility and it doesn't show my wireless network or any network in my area. I've tried running it with Windows "Manage Wireless Network". I try to add the network and it says there is a "problem found". "There might be a problem with the driver for the Wireless Connection Adapter" is what it reads. Windows installed the driver initially but I installed the same driver from Trendnet's website and I get the same thing. I'm kinda baffled by this because I had no issues with Windows XP and this card on the same laptop. Here is my ipconfig
