I have FC909A running in dual stack mode (STA + AP). The range of STA mode is ok, the data connection works at about 40m distance behind corners in our office.
The AP mode has a very short range. The data connection stops working (ping stalls) at about 6m distance. The distance is a lot better when there is no-one in the office in the night but if someone is using WiFi, this problem happens. The AP is configured to run in a channel where there are no other WiFi networks. I have confirmed this by checking with “WiFi Analyzer” application on Android. That’s strange, it’s as if traffic on another channel disturbed the AP.
Environment:
- linux 5.15.71 on iMX8M
