Ping time jumps from 20 to 300ms.

[slavaman]

We are using several boards with rtl8723au and noticed not stable connection and ping (20-300ms). If we decrease (yes - decrease) ping interval we get stable ping.

It's impossible to work with it.

Does anyone know this problem? Is it possible to solve it?

Thank you.

That sounds like a power-save problem. I did not think that most APs were that aggressive, but who knows? Try loading the module with the "rtw_ips_mode=0" option.

Thank you for your reply.
We tried

options 8723au rtw_ips_mode=0 rtw_power_mgnt=0

but had no effect.

have the same problem - sometimes ping jumps from 20 to 1000-7000ms
