Windows 7: Windows 7 cannot detect any wireless networks

Windows 7 cannot detect any wireless networks

Hey guys,

I did a clean install of Windows 7 on my desktop last night upgrading from Vista. The install went smoothly and all was working until I tried to install my wireless adapter (TrendNET TEW-424UB) and discovered that although the driver installed, it could not detect any wireless networks. My first thought was that the adapter just wasn't compatible with 7 so I went out and bought a DLink DWA-125 only to discover I'm having the same problem. So I googled this problem and discovered that a great number of people are also having trouble with Windows 7. After browsing through the forums I've been unable to find a general fix for all of this, I found something about the WLAN config utility that 7 has, I disabled it and tried uninstalling/installing the adapter drivers with no luck. And then the same thing when re-enabled it again.

*Edit* I forgot to mention, the network works perfectly without a problem. As I type this there are two other computers connected via wireless to it and when the computer had Vista installed it worked without a problem.

So my question is, has this problem been solved yet or am I stuck without an internet connection?

Thanks for your time.

Hiya pal and welcome to the forums.

Is there any chance you could let us know what make and model router you have

Windows XP - Now Windows 7 Home Premium (64-bit).

Is the wireless adapter showing in device manager? Regarding "WLAN AutoConfig", yes make sure it is enabled and set to automatic. Also, can you try disabling IPv6 in network settings.

Oh sorry I forgot to add it in, the router is a Linksys WRT54G, revision 8.
