loss of connectivity every few days
I've had my personal netgear cable modem connected fairly stable for about 5 years. I recently upgraded bandwidth and took advantage of a promotion with a new XB3 modem provided by XFINITY and in the last month I've had about 8 instances where traffic simply stops. The modem lights indicate connected with upload and download, but there is a complete loss of connectivity for any usable sessions. Unplugging the modem, waiting 30 seconds, then plugging it in restores connectivity, but it sure is a nuisance to have a work and school disrupted.
Could it be interface errors building up?
