I get this to use with Comcast cable internet since it be on there approve list -lrb- leave 6 year of crappy att dsl 6.0 Extreme which just seem to get worse and worse as we use it and add on more device -rrb- . Works great and be easy to install . sine it be pair with a Netgear 3700v2 router it be in `` bridge '' mode which Comcast have to do for you , so you can not see any specifics about the modem once it be behind the router , which be expect . I have look at they and it seem to be work very fast with Comcast . we get a clean signal 6-10 m ping , no packet loss and 25mbp down and 4mbp up , which be great since we have 5 computer , 3 PS3 's , 5 pda -lrb- iphone , android -rrb- phone ,5 hd\/dvr Directv reciever with whole home dvr hook up to internet and a att Microcell Tower which which work like VOIP for better cell phone coverage . so you can see we be task this thing and it just keep on go . my 3 kid do a lot of online multiplayer gaming mw3 , battlefield 3 , etc. so we use alot of datum for gaming and Netflix , Vudu video download \/ streaming , last month be 465gb datum use . anyway it work well and have get good review feedback by other .
