SB6141 speed issue. DS Partial Service Fallback

I have had a tech out with no joy. I am paying for 30 meg service and it is usually around 1 meg or less. Any help would be appreciated!

Re: SB6141 speed issue. DS Partial Service Fallback

I believe you have 2 seperate issues, repost the signal level page again.

Do you own this modem?

Are you internet only?

 Are all connections a tad more than finger tight?

Is there an amplifier in line?

What sort of router are you using and are connections wired or wireless?

Re: SB6141 speed issue. DS Partial Service Fallback

I will repost the signal level as soon as I get back home. The signal levels do seem to be consistent though.

Yes I own the modem.

Internet only. 

All connections are tight.

No amplifier that I am aware of.  No splitters are used.

Wired connection. TP Link AC1750 is the router. Problem exists even if wired straight into computer bypassing the router.

Re: SB6141 speed issue. DS Partial Service Fallback

While it could be a line issue, That's starting to look like a bad modem or power supply, I'd suggest trying another.

 When you get home, see if those errors are sill occuring, also paste the FW version/ date from the help page.

 Then do a reset to default which will show up only if you disconnect the coax. Need to find out why those errors are occurring.

Re: SB6141 speed issue. DS Partial Service Fallback

That is the firmware they loaded in the past month... Did this occur before that?

Re: SB6141 speed issue. DS Partial Service Fallback

I don't think so. (On the question on the firmware)
