It's quite inexplicable, but it looks like a compatibility issue with a router. I suggest trying a different router. Leave it open for days temporary to see if anyone have the same problem.

I experience this with airportitlwm (always bad on 5 GHz ac, not as bad on 2.4 GHz n), but not with itlwm + heliport.

routers: several models from different manufacturers
card: Intel 8265
OS: 11, 12, 13, 14 (currently on 14.4)

@Scharkenberg For your case, was it normal on v2.2.0 stable version?

zxystd commented 3 months ago

@RIPDucky24 Tested with 7260ac about 26 minutes，very smooth speed.

Ok yeah then it's probably my router then, I'll go ahead and speak to my isp to get me a replacement. Thanks!

I have been using 2.3.0-alpha for the past year. AirportItlwm 2.2.0 doesn't have a Sonoma release, so I could not test that combination.

I ended up reinstalling Ventura, where 2.2.0-stable works more or less as expected (connecting to known networks after reboot/sleep is slow, otherwise speeds are mostly stable and there are no sudden disconnects). Should I plan on staying on Ventura for the time being? Or can 2.2.0-stable also be compiled for Sonoma perhaps?
