I have a history of upstream problems with my Terayon, marginal signal gives exactly the symptoms as described, and if you monitor forum posts there are a lot of these 5 year old Terayon modems failing at the moment, the UBR change to QAM 256 seems to increase the sensitivity - but apparently no problem in theory.

The Terayon has a maximum upstream of +58dB, newer modems can go up to at least +61dB. As it only has a 10Mb/half duplex Ethernet port the TJ210 cannot make full use of 10Mb/s connection - mine could speed test to over 8Mbps with TCP/IP tweaks but never got more than 5 or 6Mbps in real downloads.

But when it works it handles 4Mbps fine.

When the cable for my 64kb/s modem was installed the technician could only measure there was a signal in the house - he had no modem or laptop.
