Hallo zusammen,
seit jemand vor ein paar Monaten im Urlaub versucht hat, mit meinem Laptop ein bistimmtes W-LAN zu erreichen, geht bei mir gar kein W-LAN mehr bzw. ist so langsam, dass sich keine Seite aufbauen kann. Internet über Kabel ging übrigens noch nie. Nur mobiles Internet von o2 geht, das ist aber zu langsam. Nun möchte ich aber gerne bei meinen Eltern ins W-LAN (die haben eine Fritzbox), aber es funktioniert nicht bzw. vielleicht bin ich auch schon drin, kann aber keine Internetseiten aufrufen. Oben rechts sind auf jeden Fall zwei Computer auf meinem Laptop abgebildet. Leider habe ich noch nicht besonders viel Ahnung von Linux.
1. Ich möchte meinen Laptop (Fujitsu Siemens) mit der Fritzbox Fon WLAN 7270 (von 1&1 HomeServer+) verbinden.
2. Ich habe Ubuntu Version 8.04 (Hardy), Kernel Linux 2.6.24-27-generic, GNOME 2.22.3. Die Netzwerkkarte wird bestimmt erkannt, denn ich kam ja schonmal hier in dieses W-LAN 'rein.
