Having random disconnect problems (wireless), my net just seems to disconnect for like 1 minute and them reconnects like a minute after. My iPod and other computer seem fine with no problems so I doubt it's the router/modems' problem.
Willing to vouch/review services on my spare time. PM/VM me.
Got comcast and a SBG6580 Wireless Cable Modem Gateway. No lights are blinking on it.
Hm,I had At&T and my router started doing that,at first I thought it was my computer but it wasn't.I ended up calling them and ordered for a technician to come look at it.They replaced it with a recalled router which failed within a day,and then I got a better one from them for free.
I suggest calling a Comcast technician to come and take a look at it,but before you do that,make sure all your cables are connected and none of them are loose,ripped,etc because they will probably try and ask you that when you call.Also,that router has low ratings lol.I hear Comcast has terrible customer service,so good luck man
