I've got through countless router upgrades over the last 10 years. Last time I spent some extra cash and got myself a Billion 7800N which has been really good. As I've not got cable I'm only using this in bridge mode acting as a wireless router and gigabit switch. I've recently moved house and notice that I'm not getting enough range out of it - I figured its several years old now and wireless tech has moved on an awful lot in that time. If I was looking at upgrading it what would be decent equivalents?
