I recently purchased a Nighthawk x6 ac 3200. I live in a large house and the previous router ( 5 year old Asus) lacked the range that I need. The new Nighthawks range is much worse and even with several repeaters is poor. If I keep it I will need to set up more repeaters. I tried to log into the routers web page to see if I could make any adjustments, but even this was problematic and I could not find using the address that was provided. I've had good luck with Netgear products in the past, but this thing is very poor. Any ideas before I return this thing to Amazon?
