I have Cox Cable in San Diego County. Our connection drops three or four times a day and these are the errors:

cox came out and told me that everything looks good as far as they're concerned. What now? I spoke with Linksys but they act like they're clueless.

I just spoke with Linksys and they told me that a hard reset is one of two suggestions. If that doesn't work the other suggestion is to replace it. Great!

I replaced it and am getting the same errors!
