So I've recently just made made the switch from Windows 10 to Kubuntu 16.04.02 LTS. For clarity, I'm an adolescent linux user - fresh and new to linux.

I would like help with the following issue: The issue is that my wifi shows all available connections, but once I put in all necessary details (such as username, password, security details) and try to connect, I get a KDE Daemon pop-up saying "for accessing the wireless network <network name> you need to provide a password" -immaterial if i enter my network password or even my laptop password here, the pop-up still reappears like 10 seconds later asking for the password again. Following this, two little pop-ups come up saying "Connection <network name> deactivated" and "wireless interface (wlp2s0) No secrets were provided".


I am using a Dell XPS 13 laptop with Intel Broadwell Core i5-5200U CPU, 4GB RAM, 256GB SSD.

Through the Konsole command: lspci -vvnn | grep -A 9 Network
I found that I am using a Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter
My PCI-ID is 14e4:43b1
The Kernel driver in use: bcma-pci-bridge
The current Kernel I am using is 4.8.0-36-generic


Thank you!

Hello agonsalves,

The messages you are receiving are a little unusual - maybe translation - but I'm wondering if you maybe have an issue with a missing wpa_supplicant. Can you verify if it is installed ?

Another possibility - Broadcom wireless adapters can be notoriously difficult to get to work. The good news is that it is always possible, sometimes with a little trial and error. You should verify that the kernel driver you are using (bcma-pci-bridge) is the right one for your particular chipset (BCM4352). For example, the computer I am using to write this has a Broadcom wireless adapter (BCM43224) and I am using module brcmsmac. An online search will be a good starting place.

Cheers.
