My Archer C60 V1 5G wireless network crashes as i connect my OnePlus 5, OnePlus 3T or Chromecast to 5G network. When this happens 5G network disappears and 2.4 G network is still available but no client is able to connect 2.4 G network but client connected via eathernet port still able to connect router. To overcome this problem i have to restart my router and everything started to work properly but after few hours same thing occurs again.I haved searched on internet about this and found that it is happening due to too many mdns request in short period of time from Chromecast and android oreo device which lead router to crash. I also find that tp link provided a beta firmware to Archer C7 device to fix this problem but unable to find any solution for my Archer C60. Currently i have disabled my 5 G network as a temporary solution and no issues occurs on 2.4 G network but i require 5 G network also as at my location there are too many 2.4 networks running and causing interference. Please provide a permanent solution if anyone have. Sorry for my bad English.
