I didnt mean to cause any offence btw, sorry if I come across that way x
Did you get yourself a new router? I'm still using my old Netgear but you can get the Netgear R7800-100UKS Nighthawk X4S - AC2600 for £129.99 if you look around. Got good reviews but not sure if you can put custom firmware on it like the Asus ones.
