Hello, recently my PC has developed a sort of problem I can't seem to fix.
I've used the internet on it countless times before with no such problem, using a wireless adapter (WNDA4100 N900) to connect to my router. Today, I try to log into Steam, and find that my internet is not connected. I have not changed anything between these times that I know of.
Naturally, I tried checking for networks, but the adapter couldn't find any. I went through all the usual stuff I could think of, turned the router on and off again, rebooting my computer, troubleshooting, and even trying the adapter out on my laptop! On my laptop, the adapter found the network fine, and connected to it. Everything was working. I uninstalled the drivers, rebooted my computer and reinstalled them; nothing. Device Manager says the adapter is working fine, and it is, at least on my laptop. I just can't get it to find my network. Or any, for that matter.

I'd really appreciate if someone could help me out on this as soon as possible. I've tried everything my extremely limited knowledge of technology allows me to do. I can't reach an ethernet cable over to the PC, so I'm stuck without internet on it until its fixed. Thanks :)


I'm resetting it to factory settings now to see if it will fix. I'll update after it completes.
 


how would I go about changing the default gateway on the wireless adapter? And yes, my router is set to DHCP
 


Unfortunately, changing what you told me to doesn't seem to work, nothing has changed.
 
What happens if you connect the adapter to laptop and walk over to your stationary desktop? Does the Wifi stay connected?
If you open Command prompt and type ipconfig /all does it list the IP you expect and is the DNS address AND default gateway same as your routers address?
Are you running B/G/N-mode? Do you have a wifi password? Are you filtering connections in router? Like only certain IPs are allowed, Mac-addresses.
How many IPs does your DHCP service hand out? Is your Wireless transmit power at High?

It has to be some setting somewhere.
