Liebes Forum,
ich habe folgendes Problem mit dem WLAN-Zugriff meines Notebooks Acer Aspire 5050: WLAN funktionierte nach der Installation von 10.10 seit ca. einem Monat ohne Probleme. Seit dem neusten Update auf die Kernelversion 2.6.35-24.42 wird die Verbindung nach ca. einer Minute eingebremst und bricht phasenweise ganz ab, so dass ein Surfen, Streamen, Installieren oder Updaten nicht mehr möglich ist.
Bei meinem Netbook Acer Aspire One 110 (Lubuntu 10.10) mit der Kernel-Version 2.6.35-23.41 und dem gleichen Atheros Chip und einem Windows-Laptop funktioniert alles perfekt, während der Acer 5050 immer wieder einbremst. Leider habe ich den alten Kernel schon entfernt, weil alles zuerst so aussah, als ob der neue perfekt funktionierte.
Anbei einige Informationen:

Können die Probleme tatsächlich mit dem neuen Kernel zusammenhängen oder ist es was ganz anderes?
Besten Dank schon mal für die Hilfe!
