Internet service interruption in the early am hours??
I have gone through periods where there is regular internet service interruption in the early am hours (1-3 am) in the Hampton Roads area. This seems like some sort of 'off time' network maintenance but is rather frustrating when it is not your 'off time' The latest was on 2/19/15 from at least 1:30-2:30 est. We gave up after an hour and found it working at 8:30am when it was checked again. Every time there is a similar issue I reboot the modem and router with no effect (both upgraded to newer models 6 months ago). Given some time, it will 'magically' heal itself and provide internet connectivity again. For clarity, during these down times network connectivity between my devices works (the router is working) but access to the internet is not available (no data through the modem).
Tech support claims they have no record of network down time or maintenance for this last event early this morning but I am skeptical that it isn't a network issue on the part of Cox as these down times are almost always after 1am.
Has anyone else had similar experiences?
Thanks,
duhmel

Cox has had email problems that they are 'working on' since mid-November. It was originally localized to the West Coast but now has spread all over. Peruse this Forum and you will see over twenty posts in the last two months. Welcome to the CLUB.

So not only are you giving out misinformation, you are posting on people's threads that it has nothing to do with? Yikes

First, if you just reboot the router after the problem happens, any effect?
Also, can you post your signal levels? They are usually found on 192.168.100.1 webpage but I can give specific if you report what model modem you have.

Thanks for the tip about the modem IP address. Modem is a SB6141 Surfboard. Signal to Noise for the 8 channels ranges from 34 to 36dB. Power levels are from -7 to -11dB. Not sure what the optimum power levels should be but Cox tech support queried the modem and felt signals were good.
Rebooting the modem, routers, etc had no effect. Some of the devices in question used wired connections to router/switch so WiFi is not the issue. As mentioned, I can talk between devices on the network, just not out on internet when this error occured.
The modem has an internal event log that probably sheds some light if you are familiar with the entries.
There are entries at the time of loss of internet service, when I did a power cycle and then about an hour later.

Anything under 36 is bad. Main thing in the logs are T4's, which are usually caused by low downstream DNS like yours. Any splitters you can bypass? If not, I would suggest a technician.

Is a signal to noise under 36 bad or power levels under 36? I just noticed another table in the status page that had power levels that are higher than 36. The next time this happens I'll take a snapshot of the status page on the modem.
Thanks for your help

Are you hardwired into the modem or are you using a wireless connection? If your wireless, I would recommend connecting directly to the router with an ethernet cable. If those speeds are unsatisfactory the next step would be to bypass the router and connect directly to the modem. That will let us know which piece of equipment may or may not be the culprit. For further assistance, please email us at cox.help@cox.com include your account information and the speed test results.
