If anyone looks for a new router which can get closer to 1gbit be very careful as to where you chose to source your information. I have just done a quick google to see if there have been any reviews and tests done specifically for routers that can do 1gbit wan to lan and this website came up as one of the top search results.

At a cursory glance it looks professional and legit but the information is obviously a load of twaddle. I have checked on smallnetbuilder and the Asus AC5300 comes out at 937mbits which would be good enough for me. If I was looking at one seriously I would check to see if newer models have been released since and what the stats are.
