My up/down is great and as advertised -- around 250 each with strong signal, sometimes a bit higher, sometimes a bit lower.

BUT I will say that the router they provide has frustrating periods of weak signal that effectively kills the bandwidth. There will be one day every two weeks (maybe? on average?) where for 20 minutes of every 30, just being at my desk 15 feet / two walls away will drop me down to 3-5 mbps, with my Windows wifi signal showing 2 or 3 bars out of 4. It's a mystery, and can be very frustrating, because with my partner and I each working from home on opposite sides of the apartment with the router in our bedroom in the middle, during those periods neither of us has good signal.
