Re: Missing WiFi - Dell XPS 15 9550 - Broadcom Limited BCM43602 802.11ac
Code:
auto lo
iface lo inet loopback
iface dsl-provider inet ppp
pre-up /bin/ip link set wlp2s0 up # line maintained by pppoeconf
provider dsl-provider
auto wlp2s0
iface wlp2s0 inet manual
This is your /etc/network/interfaces file. First, do you really have DSL authentication required for wireless only and not ethernet? I suspect that you got these from some forum post and really don't require them. If you do have DSL, the by far better way to accomplish authentication is in the router or DSL modem.
Second, the 'iface wlp2s0 inet manual' line is meaningless. It probably should read 'static' and not manual, and then the address, gateway, SSID, password, etc. need to be declared. It isn't. I suggest that you edit the file to return it to its default state:
Code:
auto lo
iface lo inet loopback
Then let Network Manager do its job. If NM doesn't see your connection, then something else is wrong and putting random lines in /etc/network/interfaces isn't going to fix it.
And, as we see, something else IS wrong:
Code:
[ 3.050625] [<ffffffffc1988084>] wl_module_init+0x84/0x1000 [wl]
That type of entry in the message log usually means that there is a problem loading and initializing the module. I think it has trouble initiating because it's the wrong driver! http://askubuntu.com/questions/88429...-pro-dual-boot
Please try:
Code:
sudo apt-get purge bcmwl-kernel-source
Reboot and then:
Code:
sudo modprobe brcmfmac
If the wireless doesn't start immediately, let's check the log for clues (firmware?):
