Hi,

Yet another one having problems with loosing 5Ghz network. I've tested a lot of the "fixes" mentioned in various threads here at the forum. Checked firmware, set fixed values for channels, reset devices (router & phones/tablets/pc's), aso.

2.4 works fine & wired works fine. Trying to connect 5Ghz says that either the network doesn't exist or that the password is incorrect (which it isn't). The 5Ghz is visible for all clients, but no device can connect to it.

The last tests I've made is to analyse the HomeCare parts. It seems to be the "Infected Device Quarantine" that cause the problems. Having the 2 other parts enabled (Malicious Content Filter & Intrudion Prevention System) it appears to be working fine (either one or both of them enabled). But as soon as I enable the "Infected Device Quarantine" functionality I loose the 5Ghz - if not directly, within a day. 

So, currently it's been working for several days (without the "Infected..." enabled). But it would be great to be able to use all features of the router I've bought.

Thanks in advance for some guidance and help.

Update January 24th:

I lost the 5GHz network again, so it's not the "Infected..." setting that cause the problem - it just makes the 5GHz network disappear much faster.

i know I'm not the only one with this problem so please pay some attention to this TP-Link!! I'm strongly thinking about returning the router and change my reviews in different Swedish review sites.

So far I've seen recomendations to disable the ax-network or change settings so the wifi becomes slower. That can't be a solution. It's like buying a Porsche and get the recomendation: don't use the higher gears and don't drive over 50km/h...

Thanks in advance for attention and a firmware upgrade that solves this problem!
