Liebe Foren Gemeinde,
leider habe ich unter Lubuntu ein Problem mit der WLAN Verbindung, diese geht nach einiger Zeit verloren. Diese Zeit variiert zwischen wenigen Minuten und etwas über einer Stunde. Durch Netzwerk deaktivieren und anschließendes aktivieren kommt eine Verbindung wieder zustande. Informationen über Kernel und Karte

Aufgrund der Informationen im WIKI: zu WLAN https://wiki.ubuntuusers.de/WLAN/ und Linux Wireless: https://wiki.ubuntuusers.de/Linux_Wireless/ habe ich die dort empfohlenen Pakete heruntergeladen und installiert:
sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential
Danach habe ich versucht die heruntergeladenen Treiber zu installieren, was aber schon bei "make" aufgrund fehlender lex scheiterte
