Hallo liebe Linuxer, das ist mein erster Post hier. Habe lange mit MS-DOS, dann mit AIX und Co, dann mit Windows und dann mit Linux (Suse) gearbeitet. Nun nach Jahren mit Win7 ein kleines HP-Notebook mit Win10 als Schreibmaschine gekauft. Die 32GB-"Festplatte" ist für Win10 einfach zu klein. Fedora und Ubuntu ausprobiert und letzteres gewählt. Sogar WLAN und Akku funktionieren, ABER: Der WLAN-Empfang ist sehr schlecht. 3m Luftlinie = Abbruch.
Habe dann nach Recherche folgenden Befehl ausgeführt:
echo "options rtl8723be swenc=1 fwlps=0 ips=0 ant_sel=1" | sudo tee /etc/modprobe.d/rtl8723be.conf
Brachte aber nur etwas Besserung, jetzt funktioniert immerhin gerade noch 6m Luftlinie.
Infos zum System:
