Re: T400 intermittently dropping wireless connection ever few minutes for 10-20 seconds

A few weeks ago my T400 (Windows 7) started intermittently dropping wireless connection ever few minutes for 10-20 seconds. No other computer in the house has this problem on the network. I've restarted the router, turned the PC wireless radio on and off. Any other ideas? How do i know if i have the latest wireless drivers?

Install the latest drivers using System Update, and see if that fixes the problem.

If not, try installing the Intel drivers (assuming you have the 5100 or 5300) rather than the ones found on the T400 driver matrix. I used to have this issue with very early Lenovo supplied wifi drivers, but both the Intel and Lenovo drivers work consistently now.
