Archer C6 internet connection drops for certain devices
Recently, my C6 started to drop internet connection for some devices. I noticed it first on my Android phone. While I was connected to the 5Ghz network, I would suddenly find that there's no internet, even that the network is connected. If I disconnect and connect again my Android phone will show "Connected to network. Can't provide internet". If I switch to my 2Ghz network, I have internet. Only way around it was to restart the router. It happened for my laptop as well. Now it is happening to my PlayStation which is connected through cable. Suddenly the internet will stop working and when I attemp to re-connect again it fails the tests. I have then to switch to Wi-Fi, which could work for another while then it will as well stop working and then neither cable or Wi-Fi works and I have to restart the router.
I was running on 1.3.6 Build 20200902 rel.65591(4555) until about 2-3 months ago then I upgraded to latest firmware. Yesterday I thought reverting to previous firmware build may help but it didn't.
Did anyone else ever experience a problem like this? and do anyone know of a tool that I could use to collect useful information while this issue is happening?
Thank you
