[SOLVED] Really slow internet / wifi on Linux Mint 20.2 Cinnamon

Post by PringleBeagle »

I'm new to Linux, having moved from Windows a couple of weeks ago. Internet speeds were fine at first (and were blazing fast on Windows). Now tabs take minutes to load, and sometimes time out before they do. Image-heavy sites seem worst affected, but everything runs slow, including when the computer updates. Now I think of it, even launching programs feels slower than in the first couple of days (noticeable lag launching even the textfile application).

Here's what I've tried:
  • Speed issues are the same whether Firefox or Chromimum, with and without add-ons disabled, and with / without a safe session launched from terminal
  • I've refreshed Firefox - didn't help
  • Private browsing - no difference
  • No difference when connecting to my phone's data source instead of the wifi at home
  • No difference whether Firefox is sandboxed in Firejail or not
  • Have upgraded Kernel to 5.13.0-22-generic - no difference
  • No difference whether connected through ProtonVPN (free) or not
  • Have even tried turning the firewall on and off - no difference
  • EDIT: I've also tried disabling IPv6 - no difference
When I look in Driver Manager, I see the following message. However if I choose the first option, wifi becomes completely disabled.

Code: Select all

Broadcom Inc. and subsidiaries: BCM4313 802.11bgn Wireless Network Adapter
This device is not working.
[] bcmwl-kernel-source
Version 6.30.223.271+bdcom=0ubuntu8
Broadcom 802.11 Linux STA wireless driver source
[] Do not use the device
Here's what iwconfig reveals:

Code: Select all

Hoping someone can guide me to a solution!

 sudo apt install --reinstall bcmwl-kernel-source 
Reboot

If no better, let's see again:

Incredible! Thank you, this seems to have fixed it :D

Download speed this morning was around 2Mbps, now it's 12Mbps with VPN enabled, and 30 Mbps without. Finally my computer feels like it works again. I'll mark this topic as solved, but if I can ask a supplementary question: is it worth upgrading to a paid VPN so I don't sacrifice so much speed? My paid VPN is a Windows product so I've been using Proton Free since migrating.

Thanks again!
