@FraPri Thank God i am not using TP-Link router anymore. Now i am using Amplifi Router and will never look back.

@Kevin_Z Yeah, but these very important suggestions has been said to you 4 month's ago and still nothing has happend in soon 4 month. How much longer do we have to wait.

They will tell you that you dont need to change channel in Wifi because Deco will choose best wifi channel for you :)

@Kevin_Z Is that the US firmware version of Beta? Do you have the EU firmware beta version? Since i got NO help from tp link support e-mail or live chat about my issue with Archer C2300.

@Plink Plink, how does the beta firmware work for Archer c2300 ?

Same thing is happening but with Archer C2300, some settings are changed in router (dont know exactly which settings) and then 5Ghz in 80Mhz is not working at all or keep droping all the time. So...
