I have problems with my internet. I have roadrunner and my modem is Motorola SB5100. The problem is that the connection drops constantly, almost every day. Usually just for a minute, then it starts working again and then it goes down again about 5 minutes later. I really don't know how to explain with detail but hopefully its understandable.

Downstream value

Frequency 567000000 Hz Locked
Signal to noise ratio 37dB
Power level -6 dBmV

Upsteam Value

Channel ID 3
Frequency 34000000 Hz Ranged
Power Level 55 dBmV

Like I said, this happens about every day, it disconnects from 1 min. up to 30 minutes. Theres been one or two days where its been down for the whole day and I cant access internet until the next day.

I hope I get help, because its really needed.
