Hello everyone;

Ever since I changed my Telo configuration at 172.27.35.1 to open port 80 so I can access the Telo setup page from my PC (My configuration is Modem=>Router=>Telo) and gave the Telo device a static IP address with my Netgear WNDR3700 Router address reservation feature, I have been experiencing random modem reboots/resets or whatever you wish to call it.

It usually happens after the computer has been idle for a while, or when it has been in hibernation and then I wake it up, then Open Internet Explorer, immediately I notice my SB6120 Modem reboots, and then my speeds are very low. I'm clueless as to what might be wrong, Maybe there's an IP conflict causing this because of the changes made to the Telo or is this pure coincidence?

Any help would be greatly appreciated!

I've been running in that configuration since January 2010 with no problem.

Connect to

192.168.100.1

which is the web page inside of the SB6120.

Go to the Help page and compare it with this.

Model Name: SB6120
Vendor Name: Motorola
Firmware Name: SB612X-1.0.3.3-SCM00-NOSH
Boot Version: PSPU-Boot 1.0.0.4m1
Hardware Version: 3.0

That is the latest firmware for the SB6120.
There were reports of earlier versions of the firmware being unstable.

Only your ISP can update the firmware.

Hi Murphy,

Thanks for your help, Here's my Firmware version:

Model Name: SB6120
Vendor Name: Motorola
Firmware Name: SB612X-1.0.3.3-SCM00-NOSH
Boot Version: PSPU-Boot 1.0.0.4m1

Ely: The modem log should tell a lot of the story. But you need to cut and past the log contants here for us to view them.

BTW, I'm crossing fingers as it hasn't rebooted today yet!

Ely:
The modem is seeing power losses. Either there are power interruptions in your home's power, or the modem is defective.

This modem has a history for this type of thing.

You could see if you could get the current version firmware updated again.

Murphy would know more about that than me.

Well the power interruptions are because I remove the power so I can reboot it so it works normally again, The problem actually occurs after these messages:

Apr 12 2011 06:08:34 5-Warning T07.0 RCS Partial Service;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0;

Not sure if that log entry happens BEFORE or AFTER the modem reboots by itself immediately after I open Internet explorer, and it has also happened ONCE right after bringing the PC back from Hibernation mode, the power reset is me recovering from the reboot, because after it happens the web gets really really slow or I get no connection at all.

The reboot might also happen after this:

MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0;
Apr 11 2011 20:45:19 6-Notice MDD Recovery following MDD Loss;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0;

Not really sure, but the power resets it's me.

Ely:
Something else to try:

This may not help, but it won't hurt.

Try turning off MAC Address Spoofing, which can cause confict with your modem or router, in your Ooma device. Go into your Ooma Setup pages. Click on Internet settings. Go down to INTERNET port MAC Address:. Click on the "Use Built-In MAC Address" button. Click on Update.

Try it and see what happens.

Go to the modem's Signal page and tell us what the downstream signal level and signal to noise ratio are.
Also the upstream power level.

Also thunderbird, I noticed the one being used is the same as the one built in, nevertheless I did what you said, selected "Use built in MAC" and clicked on Update.
Thanks so much guys!
