The kids started to complain that their game on the PS4 is laggingWhat do you mean by that?
I've also noticed that on my laptop suddenly would loose the wifi connection (or the connection would just freeze)
It says it's connected but you can't even access the router/default route (using the web GUI)
If I try a PC with a wired connection at the same time it all works fine.
I had to restart my router 3 times yesterday...it works for a few hours and then gets unusable.
Went back to RT-AC68U_374.43_36E4j9527 this morning and since then everything is stable again.
