Ok so i have had this Modem since i switched to Comcast High Speed cable about a year ago and everything was fine for a while untill suddenly my internet starting going out on me randomly. after about a week of it i had someone from comcast come out and they told me it was because i had the modem connected to a booster. they took it off that and it seemed to work. up untill about 2 weeks ago that is. my internet will still go down for no reason (it seems to go down a lot more often when playing a game). it is connected to one computer through USB without a router. i have tried to connect through ethernet and that makes absolutley no difference. I dont think i forgot anything about it.... if anyone could let me know if this is just the modem crapping out (if that can even happen)? or maybe its something else. i can only think it might be the modem but before i spend 50+ dollars i want to see what others think. Thankyou for reading.
