Input:
Save money from the monthly modem rental fees and buy this one for keeps. I honestly believe that Comcast's piece of crap modem they gave me for rental (I believe it was an RCA-brand modem) caused my connection to drop off at least once a day for a few hours at random times of the day. Ever since I bought the LinkSys BEFCMU10 EtherFast Cable Modem, I've never been kicked off once. Comcast is still my cable provider, but now (thank God) I have a different modem. Save your money and sanity from the crappy Comcast RCA rental modem. You'll thank me later.
