Speed up wifi with Broadcom BCM4321 and elementary OS Juno












1















I'd like to speed up my wifi connection. I'm using elementary OS Juno, Kernel 4.15.0-43-generic and a Broadcom BCM4321 [14e4:4328] (rev 01). The wifi connection works, but with 3-10 Mbps (download) it is much slower compared to different laptop running elementary OS Juno, which is connected to the same network and reaches up to 50 Mbps (download).



What I've done so far:




  1. At first elementary suggested via AppCenter the Broadcom STA driver (in lshw -c network it showed up as wl0) which didn't work well. Connecting to my router didn't always suceeded and the connection was awful slow, I guess something lower than 1 Mbps.

  2. Then I tried the b43 driver, which works much better. Connecting to the router always works and reaches a download speed up to 3 Mbps

  3. I disabled ipv6 in the network settings (not via terminal) and managed to speed up the wifi up to 10 Mbps. This is the current state.


What else could I try to speed up my wifi connection? I read that disabling 802.11N could help, but I didn't found out how to do that with a Broadcom card. On top of that: Isn't it stupid to disable ipv6. It seems to me, that ipv4 could become outdated soon and I want to have a properly working wifi with ipv6?

  • Please click edit. Then, put the model number from the serial number plate (important!) for each machine into your question. Also run lspci on your PC with the faster wifi and let us know what kind of WiFi adapter it uses. And, only if your router uses IPv6 for its internal network would disabling IPv6 generate a problem.
