I found a webpage on which s.o. described how he fixed this for his Intel 5100 chipset. Since this is the same driver as for the 5300 chipset in my hw8530w i tried and my wlan works again now. Shame on Ubuntu for releasing such a buggy distribution like 9.10.
Here is what worked for me: go to http://linuxwireless.org/download/compat-wireless-2.6/ download the newest drivers (I downloaded compat-wireless-2009-11-05.tar.bz2) unpack them sudo make && sudo make install && sudo shutdown -r now HTH. -- [karmic] Intel WiFi Link 5300 sometimes not working on 5 GHz https://bugs.launchpad.net/bugs/420678 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
