Running 16.04 on a Dell Vostro 1500 with a Broadcom BCM4311 (rev 01).
I booted up recently and was unable to connect via WiFi.
I get the message that 'Wifi networks are available' but cannot connect to mine.
The issue manifests as being queried for the WPA2 password but then timing out once it's supplied, or after 1+ minute of trying to connect, again being queried for the password. The WiFi icon sometimes loses its 'bars' and becomes unresponsive after a few attempts.
The password has been triple checked and is used on many other devices.
The wifi adapter is switched on and recognised by the OS.
It is not hard or soft blocked.
I've tried the following:
sudo apt update sudo update-pciids sudo apt-get purge bcmwl-kernel-source
(all tutorials/past questions said this must be done. I got the response that bcmwl-kernel-source had not been installed.)
sudo apt-get install --reinstall bcmwl-kernel-source
(at this point after rebooting, I could not connect via ethernet to my network)
sudo apt-get purge bcmwl-kernel-source
(after rebooting, I could now connect via ethernet)
sudo apt install firmware-b43-installer
(returned message that it is already installed)
sudo apt-get remove --purge firmware-b43-installer sudo apt install firmware-b43-installer
firmware-b43-installer and rebooting, the problem remains.
I'm unsure what my next step should be. The laptop sees the wifi adapter, the adapter sees my network, but I can no longer connect to it.
Thank you for any assistance.
