Title:
14e4:43b1 DELL XPS 13 (9343) Only wireless 5GHz works, but not 2.4GHz
Status in bcmwl package in Ubuntu:
Incomplete
Status in linux package in Ubuntu:
Invalid
Bug description:
This laptop came factory preinstalled with Ubuntu 14.04, but it had
and still has way too many problems.
I have now kernel 3.16.0-37-generic running. The wireless driver is
wl, installed from bcmwl-kernel-source. I have wireless working at
5GHz with good speed, everything well. However, I can't connect to
wireless on 2.4GHz.
Before I had kernel 3.13.0-52-generic, which had the same problem. I
tried kernel 4.1.0-rc2 and rc3, but both failed on installing from
bcmwl-kernel-source.
Trying "iwlist wlan0 freq" I get a list of channels 1-14 at 2.4GHz,
and 32-66 at 5GHz. Still, only the 5GHz works. Other devices in my
house do connect well to the 2.4GHz (from a Fritzbox router).
"iwlist wlan0 scan" has "no scan result" when 5GHz is disabled, and
finds one network at 5.18GHz when enabled.
