Hi I found some info. Apparently, this kernel driver doesn't support WPA/WEP with a rate different than 11M. So, doing: sudo iwconfig eth1 rate 11M resolved the connection failures. ** Summary changed: - bcm43 errors & no wifi + bcm43 errors & no wifi with rate=54M -- bcm43 errors & no wifi with rate=54M https://launchpad.net/malone/bugs/37575
