Terribly wifi latency

JKing · 2024-12-11 16:09:40

I'm getting absolutely atrocious wifi latency, with pings to nearby servers in the hundreds of milliseconds when I'd expect somewhere around 10-12ms.

I noticed this appears in dmesg, but I don't know what it means or what I'm supposed to do about it:

Sanity checks, how many parallel Windows installations do you have and what output do you get from

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
