I looked in here and don't find anything specific to the TEW-423 and (as far as I can tell) I've done what the other "can't connect" notes recommended... My wife's desktop worked FINE....... With XP. Had a disk problem and put in a new drive, and she asked about going to Windows 7 like the rest of the boxes.... SO, I stupidly installed W7, 64-bit home, which is EXACTLY what my laptop is running...... Went fine... Works fine. EVERYTHING IS FINE...... EXCEPT, kept the Trendware TEW-423PI (rev C whatever) wireless card.... According to the Microsoft chart this IS FULLY COMPATIBLE with W7 64-bit with the latest driver, WHICH I DOWNLOADED AND INSTALLED. The driver now matches what is on the Trendnet site - 6.1125.615.2010 It will NOT connect to my access point....... It worked PERFECTLY when it was XP, it still sees the network but it will not connect.... The laptop connects fine using the same WPA2 protocol... We're all in the same room, 6 feet from the access point...... I've got the access point on my desktop screen in front of me. I have the password right....... It will not connect. I turned OFF WEP AND WPA security and tried it. It recognized that the network was now unsecured and WILL NOT CONNECT. I installed the Trendnet utility.... It sees the network, it churns, it will not connect... Having verified the access point is accessible with the laptop, put in the recommended driver, used both Windows 7 and the Trendnet utility, turned OFF all security on the network, and tried repeated with no luck, I'm out of ideas..... HOW do I get this POS to connect?
