Basic Internet Connectivity And Modem Help

I've been experiencing connection loss for the past 3 months and have not had any luck on getting it resolved. Similar posts have been made and it appears the firmware is the cause, yet I'm unable to manually update the firmware. Can a comcast tech please push the firmware through?

Current firmware: SBG6580-3.1.0.0-GA-07-180-NOSH

You'll have to wait until it is completely tested and released. It then has to be configured on to the local CMTS's from where it is pushed to the devices. A CSR can not help you with this.

Sivaeb,

I am having exact same issue with my SBG6580, with exact same FW version. I had called Comcast, and Motorola. Motorola has acknowledged that Comcast has to push out the latest firmware, but has not been fully tested by Comcast and also the Router at the Comcast will not be able to push new version out. Motorola was happy refund me the purchase price of the modem as long as it under the 1-year warranty. They recommended me SB6121 and external wireless router. I am about to switch them today and hopefully it work for me.

But you are better off calling Motorola and have them send you refund on 6580, to avoid further frustration.

Why not ? Some people have already received it.

My point exactly EG.

I don't see how some people can get the 3.3 update but others can't.

How is that "your point exactly" ? You made an absolute statement. In many ways, every local system is an individual one. It will take time to propagate throughout them.

You might want to consider just not using the SBG6580. Go to Amazon and take a look at the hundreds of reviews that are nothing but problems.  The best combination I have found is a Motorola SB6120 or a  SB6121 with a D-Link DIR-655 router.  For some reason these two just match up and run great with no problems. A lot of my friends are using this combo.   The D-Link is very easy to install and very fast.   Be sure to check your downstream voltage at http://192.168.100.1/  Motorola modems are very voltage sensitive. The limits are +15DvMb to -15DbMv.  Use an attenuator on the modem coax port if it is too high.

Actually, -7 dB to +7 dB is now the preferred range with -10 dB to +10 dB being the outer limits. Also, the upstream/return power level must be taken in to consideration before the recommendation of using an attenuator pad should be given..
