broadcom BCM43142 802.11b/g/n unable to connect to wifi

Hello, I am unable to connect to the internet via wifi.

After installing the OS the wifi was not available at all. So far I've installed "broadcom-sta-dkms" via synaptic package manager. Now the wifi is available but whenever I try to connect to a wifi network I get a message that network was disconnected.

I can connect to the internet via a tehtered phone.

This is the info I get if I enter the inxi -Nn command in the terminal

Network:
  Device-1: Broadcom BCM43142 802.11b/g/n driver: wl
  IF: wlp6s0 state: dormant mac: 2c:33:7a:ff:31:2d

Hi, here are a couple of other things to look at to try and resolve the issue:

Blacklist Conflicting Drivers: The kernel may load bcma instead of wl. Blacklist it by adding blacklist bcma and blacklist bcma-pci-bridge to /etc/modprobe.d/blacklist.conf.

Disable Power Management: Edit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf to set wifi.powersave = 2 (disable) or run sudo iw dev <interface> set power_save off.

Note, to edit the /etc/ ... paths start with

sudo nano then the path - this will bring up an editor in the konsole (terminal).

Hello, I have tried both of these suggestions.

Blacklist Conflicting Drivers: The kernel may load bcma instead of wl. Blacklist it by adding blacklist bcma and blacklist bcma-pci-bridge to /etc/modprobe.d/blacklist.conf.

This results in no change.

Disable Power Management: Edit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf to set wifi.powersave = 2 (disable) or run sudo iw dev <interface> set power_save off.

this results in the network icon on the taskbar disapearing altogehter.
