T420 wireless issue

Hi -

I recently had to replace my hard drive. Upon reinstalling windows, my wireless drivers did not load. I manually loaded them and my wireless worked for a little while. It eventually stopped working (potentially after I used easy tether, internet via phone/usb).

I'm not sure how I got it to work again, but I did. I installed all of the drivers twice. It didn't work. I walked away, and when I rebooted it worked.

While, today I used easy tether again. Since then, I connected to wifi.

However, I returned home, and my home wifi is not working again. It is working for my roomates, and works when I hard wire it (Ethernet cable).

Any suggestions?

Windows troubleshooter isn't working. it's first message is telling me to make sure the network is in range. It is (all bars are lit up, it recognizes my router, no range/connection issue).

Radio is on, It recongnizes the network, just won't establish a connection.

Thanks

 

windows trouble shooter is saying "Problem with wireless adapter or access point"

 

However, wireless signal strength for the router is excellent.

3 roommate after great wifi connections. And my computer was.

 

Try running the Think Vantage System Update until you are up to date.
