Hi  @Kevin_Z  

 

I have same problem, after enabling OFDMA all my 2.4 devices are disconnecting after several hours. Restart helps, but only for several hours. Disabling OFDMA  do not help to fix it.   Please fix it or give us a workaround. 

 

@shx Do you mean the issue occurs once after you modify the OFDMA setting on the router? Is the router model Archer AX73?

 

It's suggested to reset the router to factory defaults then reconfigure it from scratch since we are not sure now which modifications may cause the issue. 

 

Can I also confirm what are the devices that connect to the 2.4G network? How about the devices connecting to the 5G, are they stable?

  @Kevin_Z 

Yes, that what I meant. Yes, it's AX73. My 2.4 devices are mostly smarthome light switches, and yes, all 5ghz devices are working normally. Yesterday I downgrade firmware on it and then update it again, since then it's working stable, but I need to test it longer, to be sure that it helped.

So, I can confirm now, that downgrading firmware and updating it again fixed OFDMA bug, without resetting router to FD. I hope you fix it in next firmware, I'd like to use OFDMA.

TP link support sent me an email with a beta firmware for my Archer C80 and by now (3 days) the wifi problem is gone.

 

Thanks

  @shx  I don't know what is OFDMA, I think my router model doesn't have it  (Archer C80)

After downgrade firmware and some tests it seems the problem was with Encryption TKIP . When I'm use AES only it is working without problem to now.

@Lavis That's great news, glad to hear the issue gets resolved by disabling TKIP security. Can I know is there a reason to choose TKIP for the 2.4G network? Are there some old devices that require that?
