WiFi can't connect problem

I did a fresh install of 17.2 MATE on my Acer Aspire E 15 and I can't get my wireless in function. I installed proprietary drivers via LAN cable, did sudo update&upgrade which enabled me to detect wifi networks but I still can't connect to any of them.

This is a sort of shot in the dark, but I googled for your computer model and Ubuntu 14.04 wifi troubles. This page described a similar problem that was solved, so it might help. (It's rather lengthy, though, so grab a coffee first!)

Try this.

Connect to internet using the wired connection. Go back to the driver manager and uninstall the Broadcom STA driver. Open Synaptic and install the following two packages: b43-fwcutter and firmware-b43-installer. Restart your computer and see if wireless works.

I read that my card is not supported by b43 or b43legacy.

I think you are correct about it not being supported by b43/b43legacy but the state: dormant on your inxi results shouldn't be there

Open a terminal window and enter

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
And paste the contents of the wireless-info.txt file
