No wifi showing up in the networks tab. BCM4360 802.11ac

Support Network & WIFI
#1

Hi, I’m new to Manjaro and I’ve noticed that no wifi connections are appearing. I’m using a wifi dongle as a temporary solution, but I want to be able to just use my wifi card. I’ve looked around the archived forum for solutions, but I’m not really sure what I’m supposed to be doing.

Broadcom always been a pain. Have you tried the solutions listed at the Arch Wiki? Broadcom wireless - ArchWiki

#3

I checked the arch wiki page, which led me to downloading broadcom-wl-dkms, as the non broadcom-wl drivers did not work with BCM4360 according to en:users:drivers:b43 [Linux Wireless] which was linked in the wiki page. I also downloaded linux-headers as the wiki said the driver required it. And it ended up working… somewhat. While yes, I could connect to networks, the connection itself felt unstable and slow, sometimes it would just drop to 0 bits download for a second—it fluctuated too much to be usable.

Since the downloaded driver and package werent exactly compatible with my wifi dongle, I temporarily uninstalled broadcom-wl-dkms. Somehow, I could still connect to networks when I removed the wifi dongle. Though the same problems as I had before still manifested albeit even worse.

The wiki page lists troubleshooting options, but none of them match my case. rfkill list showed no blocked cards, and installing linux-lts didin’t affect the connection. I’m unsure whether I need to blacklist modules or not.

What else can I do?

Just found this post from the old forum Broadcom BCM4360 wifi not working - Drivers - Manjaro Linux Forum

Might be a solution there.

I’ve experienced similar problems when installing on Mac, also Broadcom wifi.

Hi there,

I also use the a Broadcom BCM4360, the Tp-link Archer T9E Download for Archer T9E | TP-Link United Kingdom . By default, the linux drivers don’t support it you can look through the packages to find working drivers. The connection is very often lost (I tried everything), but I can confirm that some drivers will make it into a somewhat usable. Common ways are known to try and make a better connection. I do remember disabling MAC address randomization being one of them. Ubuntu’s ‘‘keep connection alive’’ setting can make the connection much better. Maybe you could try finding the script that setting actually runs. I’d be much interested in that script myself.

I’ve tried older kernels with their respective broadcom-wl drivers, but the problem still persists. Broadcom BCM4360 wifi not working - Drivers - Manjaro Linux Forum OP’s solution in this thread was to use the right version of the driver to work with the right kernel, but I’m not sure it’s any help to me since I’ve already tried the older stable LTS kernels.

#7

As far as I know it’s a issue with loading kernel modules or starting some service when booting up. I was having similar issues after last update and I tried almost everything I could think of… In the end I just had to reinstall manjaro and I’m not going to upgrade it till I know that the issue has been resolved
