[Connectivity] Something is messed up on my connection

Signal levels, modem logs around the time this happened, etc.

reply to andyross
I'm interested to hear what they say. Although I don't have any issues, while helping a friend troubleshoot his speeds, I was looking through my modem logs to see what config file I had. What I noticed was that there is no config file being loaded, unless I am missing it. My log is nearly identical to yours.

*edit
nm. I found another post after a couple hours of searching that states the config file is hidden on a SB6120 and SB6121. Hope your problem clears up.

Try clicking on the "Reset All Defaults" and then the "Restart Cable Modem" buttons in the User Interface. The name of the config file *may* then show up among the error log entries.

Haven't heard from the direct forum yet. It's still somewhat acting up today. Sometimes it's OK, then it's glitchy again.

On the Motorola's, you only see the config file after a firmware update. My log is short because I had a done a reset and reboot to see if it would clear up the issue.

If I hear nothing, I may buy a Zoom over the weekend and see if that helps, given some of the issues the SB's have with bonded upstream.

Are you using more than one tool to verify this?

This is the only one that I know of that gives statistics like that. Also, copying files to work through my VPN are horribly glitchy and slow. Downloading is fine. I ran off of my "speedy" (1.5/0.384) DSL backup connection today for work.

Still haven't heard from Direct forum. I was hoping to see if I could get the uSNR readings.

Worth a try. Hell, call 3 times and see if the number's the same from all 3. heh

If you "copy files" anywhere else, do you experience the same issues?

Why not call and ask for the uSNR? It shouldn't take too long.

Can a typical phone rep be trusted to give the right numbers and to not just make something up ??

Take the router out and go directly off the modem would be a good first step.

You need to find a problem non-VPN related as well, because there are dozens of reasons your VPN would be behaving that way. What does ShaperProbe say when run on your connection?

The issues tends to come and go a bit. I'm wondering if heat may be an issue, as these are some of the first warm days in awhile. It's marginally OK in the morning, but gets worse in the afternoon. As far as the VPN, my backup DSL had no issues with copying, beyond the normal slowness. I get a consistent 35KB/sec, which is about right for 384Kb DSL (unlike cable, DSL rates are raw and your actual rates a bit lower due to overhead.)

It hasn't really been hot to the point heat will be an issue, and if it was you would see a big swing in SNR and signal levels, and your connection beyond your VPN would be affected.

Please run that first test again without your router and see what happens.

Can you run the visualware ROUTE test? to see if it points to any specific hop.
