I have Comcast and purchase this wireless gateway -lrb- cable modem & router in one case -rrb- to use at home for a few reason . 1 -rrb- to stop pay Comcast $ 7 each month to rent a cable modem , 2 -rrb- to upgrade from a old Linksys 802.11 b router that limit download speed and have only the -lrb- not very secure -rrb- wep encryption . installation of the Zoom 5350 be easy , instruction be very good . everything be great , in fact , except for the wireless range . this 802.11 n product should have more range than the Linksys 802.11 b router from 2000 that it replace . at least in my house it be substantially inferior to that older router . I try different orientation of the case and different height in the room -- no improvement . I return the product today to best buy -lrb- no problem do that -- thanks best buy ! -rrb- and replace it with a zoom 5341j cable modem and a Linksys 1550 wireless router -lrb- 2.4 GHz only -rrb- . this combination of two separate device work much , much better . the cable modem electronics be probably identical to those in the Zoom 5350 , but the Linksys router be obviously either a stronger signal or a better -lrb- set of -rrb- antenna -lrb- s -rrb- . everyone 's house be different , but if you have a small house with not too many interior wall , then the Zoom 5350 might be a great product . if you need better wireless coverage , I would recommend the Linksys 1550 router and a separate cable modem .
