Rt-AC3100 fail on 5ghz

[KAwifi]

hi,

I have a rt-ac3100 about 1 year ans it works very well. So, i have update de latest asus firmware about three weeks and now on the 5ghz band, i lose my connection many time. For exemple, if i go on ebay app, i have the error message that ebay have no connection. Same thing whit internet. When i open a page, Safari told me is unable to open the page but some other page are ok. To resolve the problem, i have to close wifi and connect it again and all the internet page are ok, same thons for others app. I have change my firmware for the latest Merlin and it seem to works better but the problem still continu.

I dont know how set up the 5ghz band or other settings. I use a MacBook Pro, iPad Pro and Apple TV 4 on 5ghz. I have disable the beamforming and mu mimo.

Please help me with that trouble !! Thanks !!

Have you tried doing a Factory Reset on your router? That should resolve your issue.

Once you can connect to 5GHz, you can optimize your connection. This guide helped me when I was getting started: https://www.rickygao.com.au/blog/tuning-the-asus-wireless-router-to-best-performance/
