SB6121 Not Bonding after comast removed it ?

About a week ago my internet did not worl.  After several calls found out my SB6121 was removed by mistake

They added it back and seems to work ok  Speed test said I get 100 MB download and 6 MB upload

I Noticed upload and down light are Blue now instead of Green

My download  power level is -5dB and upload is 54dB   

I always had a level problem where I live , but comast unable to fix it

I hate to call customer service

Do you have any splitters and if so try bypassing them to see how your levels look at that point.

Removed splitters and swapped with the TV connection at the wall.  Same problem

BTW the ARRIS TM722 has the same problem.  I use it for voice only

You may want to consider using a drop amplifier with an active return. You can Google that for more info. Comcast should really fix this right. And they should provide an amplifier at no charge if needed.

Hi gecoffin -- Were you able to locate the amplifier you had? If not, I can arrange for a tech to come out to help with this issue. Please let us know how you would like to proceed.

Hooked up the amp and rev level went from -4db to 11db  No change in lights 

Think I put amp too close to the modem 

Will try it at the 8 way splitter that comes into the house, that is where I orginally had it when comcast installed it in 2003

gecoffin -- Installing the amplifier where it was originally installed is recommended. Amplifiers should be connected near the ground block or where the drop connects to the home for the best signal and the least noise on the line. Give that a try and let us know the result.

Can you post a screenshot of the signal stats (upstream and downstream) where the amp is located now and then again after you move it ?

Just discovered that Comcast has me owing a SB6141 instead of SB6121.......

Could that be the problem ?

FWIW, the upstream is still too high and the downstream power is on the weak side.

gecoffin -- We would want to have a tech come out to adjust those levels. I can help get that scheduled for you. Please send me a PM with your name, full service address, and either phone number or account number for authentication. I will also need to know what days/times work best for you.
