Hello, I guess there are quite some potential issues which could cause that. Since you do not see any error logs one of them could be the WPA rekey IV poisoning one I encountered in the past. Do you have wpa rekey enabled? If so please check if disabling it fixes the issue for you. Assuming you are only using a WPA passoword and not EAP you can check if you have rekey enabled from a CLI on the router with the folowing command: "uci show wireless | grep wpa_pair_rekey" You have to delete any config statements found by the command and restart the router (or wifi) to apply the changes. If that helps, at least one STA is sending frames using wrong IV's and tricks the other end into dropping valid frames. In that case I can offer some options how to work around that, but I'm not aware of a real fix and disabling rekey is still probably the best...
