there are now two solutions. uninstall the atheros drivers (should be listed in control panel/add remove software, and also uninstall there the via ethernet drivers. this should be done, untill it shows in your hardwaremanager for the atheros card the original driver from microsoft with version 7.0.0.121 and for the via ethernetcard orginal microsoft driver version 3.57.0.442. then reboot (important!). after that, your wirless connection shows that signal strength is much less, but it finally works with best downloadspeeds and reaction time, even at larger distances. however i cant say, if it still works at a distance, where the connection already showed very weak signal, if it still finds that connection too, as the newer drivers showed a much better signalstrength in windows vista.
second solution might be the newest atheros driver card version 7.3.1.5
http://www.amilo-forum.de/files/atheros ... is_490.zip i havent had the time yet to try the internet speed overall, but the signal strength there is very high and makes no disconnection. but especially at downloads and images, version 7.2.0.199 and 7.2.0.215 seemend to drop enormously on speed and browsing felt like taking a lot of time to react. dont know if this was fixed here in 7.3.1.5
