I was actually thinking RT-AC3100. I don't really need the 8 LAN ports and the AC88U seems awfully difficult to find here in Canada (not sure why!).You mean RT-AC88U? (8 LAN port) I wouldn't buy RT-AC3100 (same as RT-AC88U but with only 4x LAN ports) for the price difference.
Are there any other differences between teh models other than the extra LAN ports?
