Specs: Macintosh , 2.4 2g
My timewarner/motorola modem/linksys wireless router keeps stopping. It has to be reset 3 or 4 times a day. Time warner has been here many times says its not them. Can anyone interpret the info below to help me find out where the problem really is? Account was fine for years and all of a sudden-this has been two years. Changed out modem and router and rewired system. Someone just mentioned voltage fluctuation which happens a lot in lower Manhattan.
Thank you.

When you emailed this log to timewarner tech support what did they have to say?

Appears to me you have a line/provisioning problem. They are the only ones that can fix this.

Answers are only as good as the information you provide.

this was a great help, thank you. telling them what you suggested is now getting a better response than the log did alone. we'll see.
