I always wondered about this - I have set up a rather large LAN network for someone's small business and they have over 100 computers on the network (almost all wired). They are currently using RT-AC66U. The R7000 obviously has a faster CPU than RT-AC66U. If you switch it to R7000 instead of the current RT-AC66U, will you see a performance increase? I know most of the PCs on the network do access Internet all the time.
