Intermittent WiFi on Toshiba Satellite C655 Win 7

Worked fine until a couple days ago, now looses connection every few minutes. Internet access over Ethernet works fine. WiFi remains intermittent even in SafeMode. inSSIDer shows there is no channel conflict and signal is strong. Router is Linksys WRT54GL. WiFi works fine for all other devices in our home. Ran MalwareBytes. No virus.

Look at the duplex (speed) settings and make sure they are on Auto Negotiate for the NIC on the troubled 'puter.

Where may I find the duplex speed setting?

ChiefIT

Go into device manager and look at the NIC card's advance properties.

Do you have the same issue when you connect to other wireless routers? Have you checked if there is a firmware update available for the router? Have you also checked for a driver update for your wireless NIC in your PC? Are you using the Windows Builtin utility to connect, or is there a 3rd party tool provided by the NIC manufacturer which you are using? Have you made sure any powersaving features are turned off for the NIC (also in device manager and the NIC's properties, and also within powermanagement of the Windows Control Panel).

Also remove the cover to where the NIC is installed and check whether the antenna cables are still properly attached to the card.

Updated Router SW. Problem remained.

I did not find a variable called "duplex speed" in NIC advanced properties, but I did try adjusting the other variables. I adjusted a variable called "Scan Valid Interval" which I increased from 60 to 80. I have not had a WiFi problem since. I'm considering this problem solved, though if anybody knows of any unintended consequences I may encounter I'd appreciate the warning.
