Hi,
I’m experiencing very slow wifi speeds.
When I test with iperf, I get these results:
root@turris:~# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------

[ 4] 0.0-10.1 sec 18.4 MBytes 15.3 Mbits/sec
This are 3 connections from the same client laptop connected via respectively wired, wifi 2.4GHz and wifi 5GHz.
As you can see, performance over the wired connection is fine, but the wifi is very slow. The 5GHz is a little bit faster than 2.4GHz, but not much. If I move physically closer to the router, then the performance improves, but only up to about 20-30 Mbits/sec, which is still very bad.
What could be the problem?
