Hi,

If the OFDMA + MU-MIMO issue bothers you a lot, then you could try this fix. https://community.tp-link.com/en/home/forum/topic/667844

  @woozle 

Much more annoy problems after it.. if you wont restart router, a  6GH'z is not more visible. And the most annoy is the 6GH'z has more weak & unstable signal compare to 5GH'z.

I also notice other problems with usb storage and easymesh, but i will create other topic if support wont answer me at Monday on email :)  bec i already send massage to them about it and maybe they will solve it. 

I adding screen how compare transmit Wi-Fi power of BE550v1 vs AX55v1 with same conditions - 2 meter away from router. 

BE550v1 its a bit weaker signal on 2,4/5GHz if we compare to ax55v1. But with same -2dBm differences between signal on frequency. 

But WIFI 6GH'z frequency its significant weaker..  -10dbi weaker signal than 5GHz.

That shouldn't be like that at all, router cost 300$!!! I know BE550v1 has internal antennas vs external on AX55v1 but TP link on site saying BE550v1 has more coverage 4 bedrooms vs 3 bedrooms (AX55v1) LINK to compare products But with that signal the BE550v1 cover just 2 bedrooms. 

I hope that is only a firmware problems... and power of signal will be better or at least 6GHs will back to normal with next update...

edit:

@Marvin_S @Sunshine Please help and send it forward to fix it.

I use official firmware from site. 

About your first question:

BE550v1 its on excaly on same place where AX55v1 was. And BE550v1 - 2,4/5GHz is weaker than AX55v1 signal. So BE550v1 cant cover more than AX55v1 but "specification" say something else. I send above i do test line of sight of 2 meters from  the router in both cases. And AX55v1 has stronger antenas. 

I also do test on my moblie phone WIFI, and results of BE550v1 its even worst.. its like Be550v1 antenas dont work on full power or just specification is a lie :))

I get emial from TP-link so i will answer there with more photos and talk direct to engineers about the probelms. Becouse its more problems with BE550v1 like usbstorage or missing easymesh functions.

Hope my testing will imporve your products bec i rly like them and use them over 15 years already.

I talk with one of engineers. I send him banch of data and he said signal is not bad. But beta firmware change dBm signal of 5Ghz band and 6ghz band in my case. I paid for router 300$ and im not i stupid customer to who you can say everything is fine and shoudl be like that. Is cleary its not "ok" and not only i have that probelms with BE550v1 signals with devices. I saw other guy here: https://community.tp-link.com/en/home/forum/topic/669282

Here is my data:

Hello, thank you for answer :)

Everytimes for both routers was same place/same setup/same range test, just same everything.

When i do my test BE550 the best position for my flat its not front to leds ( was lower signal in my case) but face the left side like on screens what i provided. Like this i had the best coverage what i can got, but still less then AX55.

Btw. Do you know anything about USB storage problems for AX55 and BE550? And when will be fixed that issue? its freaking annoying bug as hell. And more and more clients start complain about it here. 

Even more frustrating is.. i take my second AX55 to my other place. and i can't connect to USB storage by internent FTP. But to investigate it I need call first to my other internet provider and ask if  they block host ftp on 21 port.  If not.. seems just come out other bug on new firmware on AX55 lol. But i will let you know.

  @Kevin_Z  @Marvin_S 

I found inside a box of BE550v1 a little card how much dBm should has every band.

BUT WE GO THIS:

In specification we should got:

20dBm power on 2,4GHz band but we got: 18dBm

30dBm power on 5GHz (5470-5725MHz) band but we got: 26dBm

23dBm power on 6Ghz band but we got: 20dBm

That explain why signal is more weak and can cover less than AX55v1.
