I also decide to upgrade from dsl , as 1 mbp be the fastest we could get in we neighborhood . I do my due diligence and decide upon the Zoom 5350 , as it be on Comcast 's approve device list and have the requirement to meet we need . installation be very simple . I do not have a self-install kit from Comcast , so I just follow the direction for connect without a kit . I connect the coax cable to the modem , a supply Ethernet cable from the modem to my computer and everything else go very smoothly . I do not have to call Comcast with the MAC address , as everything be recognize during the install . all , in all installation take approx . 10 minute , very simple for anyone to accomplish . both my wireless laptop with b\/g wireless card -lrb- one on a second floor -rrb- find the network and connect without a problem after I enter the wap2 key . I may purchase Wireless-N card later , but I really do not see the need . speedtest show a average of 17 mpb for a wireless connection and 25 mbp for wire . I use the Ethernet port to wire my Blu-Ray player , Wii -lrb- I purchase a wii-lan converter -rrb- and a spare cable if I need to connect a laptop to stream Hulu or Comcast TV online to view through my hdtv . Netflix stream in hd when available -lrb- on Blu-Ray , Wii be only sd -rrb- and look and sound great . we get rid of we cable tv , and purchase the leaf attenna -lrb- see we review -rrb- from Mohu . so all we viewing on local channel -lrb- it find 35 of they -rrb- be free and in hd . if nothing be on that we want to view , we use Netflix , Hulu , or Comcast TV online . we be enjoy the savings , and now with the zoom faster speed , great picture quality as well .
