Cisco is synonymous with networking.
Except the EA(whatever) isn't a "Cisco". Cisco owns Linksys and puts their logo on it, but it is miles away from what "Cisco" means in the networking world.
The Arris is a decent router, but with a provider locking it down, you'd never know it. If you know what you're doing, you are definately better off using your own router.
(The WiFi in the thing is insane. Ours is on the 4th floor of a 6 story office building, back side, and I can see it from the parking lot at the front of the building. It's so loud my Nexus 7 cannot see it if it's in the same room. It's the only time I've ever seen a positive
power level... +1dbmv and it then it's blind
-- It's a business connection, so wifi is normally off.)
