Thanks though i wonder if the 4500,855 or 857 are similar in range or are the dir series routers outside of doing real dual band not either / or dual band like the 4500 any better? I'd use my 857 being the most recent as the router but when i bought the 4500 mounted it then i mounted the 855 and was very disapointed the "flagship" can't be mounted.
Anyway i'd love to know what amplify tech does over and beyond the 855 or if it's largely an 855 chipset wise with an sd slot and 3.0 usb over 2.0 in the slightly older gear. Both the 4500/855 still look more robust than the 857 which really looks fragile by compairason.
