Cable Internet Issues

Hi there! I have always been able to upload very high at 5 MB/s. I stream live and ha ve never had any issues. All of a sudden one day about 2 weeks ago my uploa d started going wacky. It drops from the low side to very low within a few seconds, and then goes from being on the very low end to having 0. Speedtests have ALWAYS come up fine, but sometimes stagger a bit while it's running. I have tried it on a few different computers, with different prog rams, etc. I even reformatted my PC.

I use TekSavvy which runs off of Rogers' lines. I replaced our modem and al l of the ethernet cables. We even tried using a different wall socket for t he power.

When doing traceroutes, 7-30 have Request Timed out, as well as 2 and 5.

I have had 2 rogers technicians in already. They have replaced everything t hey say they could possibly replace and appear stumped when they can't figu re it out.

In the event log of the modem we have: Critical (3) Started Unicast Maintenance Ranging - No Response received

Repeated a bunch of times.

It is a Thompson DMC476 modem.

I am not too sure what else to do... it worked fine one day and not the nex t. Is it possible that there was an update in firmware on the modem? Would it not have been replaced as I purchased a new one? Is there something that I have maybe missed setting up?

Thank you so so much for any input! Feeling desperate here.

Upload a different type of traffic to a different destination to see if your ISP is throttling or rate shaping your streaming traffic. You might try FTP, for example, or even NNTP. Downloads are fine?

The signal levels look fine in both directions. Personally, I prefer downstream levels closer to 0dBmV, but yours are within acceptable limits.
