Hello
I have deployed two hAP ACs in the same layer 2 network. Unfortunately I’m not able to get proper transfer speeds no matter what I try. Usually I get about 16mbps but if i’m lucky it can go “up to” 160mpbs. I’ve tested the scenario with different devices all capable of AC wifi but it just isnt working.
I think I’ve read all related or just maybe related threads regarding my problem but I’m still out of luck.
steps I’ve done so far:
upload/download tests
local forwarding
central forwarding
autonomous AP
AP reset
different power levels
static/dynamic channel assignement
tried both radios with different channel widths in 5G
tried different software versions (thats why I’m running the RC right now)
played around with hw-retries
please do not get confused by the name of the SSIDs
