Public bug reported: 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. --- ApportVersion: 2.14.1-0ubuntu3.10 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ullix 1839 F.... pulseaudio /dev/snd/controlC0: ullix 1839 F.... pulseaudio CurrentDesktop: MATE DistributionChannelDescriptor: # This is a distribution channel descriptor # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-trusty-amd64-20140620-0 DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=7b6c248b-36d3-4dcf-9e9e-427d50206af6 InstallationDate: Installed on 2015-04-24 (25 days ago) InstallationMedia: Ubuntu 14.04 "Trusty" - Build amd64 LIVE Binary 20140620-04:25 MachineType: Dell Inc.
