Internet constantly offline and high latency

Ever since we cancelled the TV and PHONE service we have been having the same issue periodically as well, goign on about 3 months now.  I get speeds up to 30MBPS then I will test again and it is as bad as 3MBPS.  Even on occasion like today around 1:05PM my modem will randomly be doing a restart cycle like COX is monitoring and doing a reboot.  Sometimes the WI-FI will also just stop working and the only way to reconnect is to reboot the laptop or reboot the modem.  Modem is plugged directly into the wall and has the same speed issues on the WIRED part too.  This also occurs if I am directly in front of the modem for WI-FI.  Once we move I dont plan on using COX again for anything, we are just stuck with them because FIOS is not here, yet....

here are my tracecert logs now that the internet is acting up, shows high latency...
