Hi there, I just switched to manjaro at the weekend. So far it has been a pleasant experience except a very slow wifi connection. Here is my system info:

I tried the fix suggested in a previous thread on this topic, creating the file /etc/modprobe.d/iwlwifi.conf
with the contents
options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8
I also tried disabling IPv6 by setting it to ‘ignored’ in the Connections section of the KDE system settings and hard resetting the router (as I have seen those tips in other threads). None of these fixes seemed to work.
I have confirmed the internet speed over wifi is performing as it should on another device. I am not able to permanently connect via wired ethernet. However, I tried this and got the full speed I expected to see.
Curiously, I downloaded a game through steam and at certain points saw download speeds equal to the maximum I saw on windows. Zoom, the software centre and firefox, however, behave in line with the measured download speed.
Also, using the speed test by ookla website I saw upload speeds at the normal level for the connection. The download speeds seem to be either 1/3 or 1/2 of the expected value, depending on what server the speed test tool connects to. That they are fairly precise fractions suggests there is some connection parameter I could tweak to get this sorted.
Any thoughts on this welcome and apologies if I failed to follow the proper posting beginners guide - I promise I tried!
