Lot of SYNC Timing Synchronization failures and lower upstream power levels on SB8200

Hi all.

 

I'm getting a lot of sync erros as you can see below. Also noticed that my upstream power levels are to low, I already got a tech visit 2 days ago due to this issue, and he change the splitters. He mentioned me that I need to wait 30mins aprox in order to see the improvements but no luck at all. Already try restarting, reseting and nothing.

 

Any recommended amplifier to increase upstream power levels? 

 

Any ideas/help is really appreciated. Thank you!

Re: Lot of SYNC Timing Synchronization failures and lower upstream power levels on SB8200

Just as a FWIW, it may not be too low. It may just be a very clean, low attenuation, and noise free return path. It may be correct for your local system specs. There are spec variances between individual systems. YMMV.

 

For the halibut, since the downstream (forward path) power is very strong you don't want that to be amplified any stronger. You could try using an upstream  (return path only) type of amplifier. It won't boost the downstream. Good luck !

Thank you for the quick reply and suggestions. I already ordered the amplifier. I will let you know the results.

Good luck with it ! Remember, YMMV. You may not need it. Please post back with how it goes.

Re: Lot of SYNC Timing Synchronization failures and lower upstream power levels on SB8200

I jsut test the amplifier and it was weird, because the signal went down 10db aprox, on the upstream channels. I ended with one Extreme splitter -3.5db. 

 

Any suggestions why the signal went down about 10db with the amplifier??

 

Thank you!

The amplifier is helping with the workload so the modem doesn't have to push much. The bottom line is if you are having issues.

Re: Lot of SYNC Timing Synchronization failures and lower upstream power levels on SB8200

So far this is the status. DO you also recommend me to put the amplifier back? Also should I combined a splitter with the amplifier?
