Looses connection

The EX6200 Nightmare. I have had it for like 2 months now, and it’s not getting any better. On the best of days it has been stable for 3-4 days on a row,. but it is now back in nightmare modus again. It is so stupid, because when it works, the speed is unbeatable. It easy manage the whole width of my which is 75/75 Mb/s. But what good is it when the connection keeps dropping like that,. can‘t even put up 5 minutes of good work even. So I have to resort to my old WN3100RP again. So weir there is no formal statement given by Netgear on this issue. I mean there has to be something to do, anyone?? Seem this thread has died out a bit. But am sure am there’s lots of others too with the same issue. I would like to hear from someone having better experiences and possible managed to work it out, preferably without lowering the connection speed of the "wireless mode".
Please, anyone care to throw some wisdom to it,. would be appreciated,.
Any,. cheers all,.
