Win 7 Wireless Network strange error on waking from sleep

October 15, 2012 at 04:20:39
Specs: Win7 Premium, AMD x2/4GB
I have Windows 7 and a Wireless LAN PCI-E card. It usually works perfectly well. Because I use Hibernate often, when the network is working, I see no problems when I next start.

However, I obviously use 'shut down' every now and again as well, but 9 times out of 10 when I start my PC again, Windows will not connect to my wireless router. If I click on the network icon in the system tray, it shows my router (BTHomeHub-3) but there is a red X next to it, and it reads:

“The settings saved on this computer for the network do not match the requirements of the network”

The only way around this is if I reset the router. Then it works fine. But I live in shared accommodation so it's not practical for me to just keep resetting the router when I have this issue, as it seems to me to be a problem at my PC's end. For instance, why are the settings fine when I have reset the router/resume from Hibernate mode, but then suddenly not fine if I start Windows fresh booted, when nothing on the router side has changed?

This has had me pulling my hair out! Any ideas?

Thanks,

Alex

Can't explain it, unless a different user is changing the router's wireless access key so it no longer matches the key you have saved on your computer. When you reset the router, it defaults to the original key again, so it works okay again.

Find out who keeps changing the wireless key in the router configuration, and tell them to stop changing it!

Please read this MS KB Article that may help resolve the issue you are experiencing.

You may also try this, if you haven't done so yet: Go to Device Manager > open Properties of your PCIe adapter > Power Management and ensure that 'Allow the computer to turn off .....' is unchecked. The default is checked.

By the way, wireless key should not change by itself and there is no default key. Default key may be considered a blank key. In this case, resetting makes it blank again.
