** Description changed:
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.
