I have an AC-3200 connected to my PS4 playstation with ethernet cable. When I turn on the PS4, my wifi crashes. I have had the PS4 checked out and it works fine at the tech shop. So I am working back to see if the router setting can be modified. I see on the web that WRTMerlin has better software, however, I am not that savvy on router software and don't want to get something that may not work. Any help would be appreciated.
