5 RTL8189 WiFi SDIO module problem

Created at 2022-07-18 00:53:49

Hi all. We use wifi module RTL8189 SDIO. In station mode, data transfer goes without problems. But if you enable work in the access point mode, then the socket periodically hangs, for 1-1.5 seconds. Drivers for the WIFI module are compiled, there are no sources. Tell me where to start looking for a problem? I don't know where to look for the problem.

It's better if you could share some more details to help us locate the issue.
Project files or screenshots are preferred.

this is a screenshot of iperf test, between device and mobile phone. The distance between them is less than a meter. As you can see, the connection is periodically broken. If a PC is connected to the device, then there are no any disconnections.
If the device is in access point mode, as soon as I connect the smartphone and run the iperf test, periodic disconnections immediately appear.
if the device is in client mode, the smartphone is an access point, then there are no disconnects.
