| [Connectivity] Failing modem? RCN problem?
My modem has been dropping offline several times daily. A reboot brings it back online. I've been told that my modem is probably failing, but I'm skeptical. Here's a log file snippet, leading up to the latest reboot. Any expert help would be appreciated.
