A few weeks ago my wireless just died. I connected via a cable on the box running PCLinuxOS.2010.1 full updated and kept trucking along. The Windows box could reach the router with no problem, so I had connectivity and just let it ride. Then I saw the release of 2010.12 and downloaded it and installed it on the Windows box. XP can reach the router via wireless, PCLinuxOS cannot, on either the KDE or XFCE versions.
The wireless card on the linux machine was a Trendnet USB "n" connected via ndiswrapper, because the included driver would not work. I tried an old D-Link DWL-510 and it will not link up either. I can see the network/router and the ESSID registers, but it will not connect, on either card.
XP is happy as a clam with either. That tells me the cards are good, the router is good and I have the right password.
Thanks in advance.
