I thought that maybe this information will be useful for other people using TRENDnet TEW-424UB wireless USB adapter or any other SiS 163u device.
Well, thing is that TRENDnet states that this device (versions below 3.x) is not compatible with anything above Windows XP. What about Vista or Windows 7? Buy a new WLAN adapter? No, that’s definitely not the case.
This device uses SiS 163u chipset, and even though TRENDnet says otherwise, SiS has a driver for Vista (both 32 and 64 bit) and it works well with Windows 7 as well. So, if you need it – go and get it here: http://w3.sis.com/download/, then accept the agreement, in the next screen select Vista Basic/Premium (even for Windows 7) from the first selection box, then Network Driver from the second, and SiS163U WLAN controller from the third. The next screen after that is self-explanatory. Get the driver and you’re good to go.
I hope this helps
