I logged into my Arris modem directly and the Power and SNR values were all within manufacturer spec, everything was OK and Online, it looked healthy.
Can you post the signal levels so we can take a look too? I am curious if you have 2 OFDM channels. 30-32Mbps is around the max speed of DOCSIS 2.0 so I wonder if your modem is failing back to that.
One agent said my modem was bad because he saw 30% packet loss to the modem from his side
Did you see any packet loss going out, direct to the modem, when he did his test? Try Pingplotter or WinMTR to look at your latency/packet loss over time.
I just found a way to check the configuration file on the SB8200 to confirm the provisioned speed. See last post by Andyross here.
"replace "comconnectstatus" with "main" in the URL, and it will show the config file."
Does that work for you? What does it show next to configuration file?
Below are the modem signal levels and details. Odd thing is, it looks like the modem got a firmware update since yesterday, as the login screen was different and my password no longer worked. I had to factory reset it to use the default login/password combo.
I also got a 404 when trying the "hidden" main page, that info seems to be part of the Status page, minus the extra details.
Darn. Was hoping that trick worked so I could suggest it to other people. However I don't think it's related to the config. file if the speed is intermittent.
What I DO see is a problem with your downstream OFDM channel. It is registering a VERY low signal(-46dB) and doesn't show a SNR. Does that change when your speed changes? Either way, I would think a technician can troubleshoot that issue.
BTW, delete the second screenshot. It shows your MAC address which should be private.
Thanks. I was curious about that 159 OFDM channel too, but couldn't find much info on its purpose or what was an in spec value. Docs only talked about the QAM256 channels and their acceptable values.
I haven't been able to reproduce the ~900Mbps download speeds yet this morning. Trying to troubleshoot in between work calls, but now I have time to direct connect my laptop to the modem and see if I can get the high speeds and observe the modem values.
