MT7603E WIFI on a MT7621 possible hanging

I don't know if this is where I should post this issue but I'm guessing that this might be related to this WIFI driver so let me just share it here. I'm using a Newifi D2 router with the latest snapshot build as of this moment. One thing that I noticed is that the 2.4ghz WIFI (MT7603E) is like there was a time that it feels like it's freezing or hanging for like 30secs or 1minute and during that moment, I can't browse to the internet or even ping my router. It's like we're connected but we don't have connections. I don't know if this is also related but I only experience this mostly when the devices connected reaches more than five in 2.4ghz. It sucks when I'm playing online games and suddenly the ping reaches 999 and it took 30secs or more to go back to its normal state so by the time it happens, I switch to the 5ghz connection so I can play again. As for the 5ghz connection, I can't test it further because only 3 devices supported in this connection so everything is smooth and normal, it's just the 2.4ghz just bugging or something.

No source file, test, or entry point is identified. Reproduce the hangs on a Newifi D2 with the MT7603E 2.4GHz connection, especially with more than five devices, then trace the driver behavior during the 30–60 second loss of connectivity; done means the stall is explained and resolved without disrupting the 5GHz connection.
