no, it is definitely a problem with the modem. Ubee confirms, the newest FW conflicts with Arris C4 CMTS's. The old firmware is being sent out, and my speeds are now worse.
I haven't used an Ubee modem, so I don't know. I was just pointing out that not all SB6120's are having issues that are related to the modem. Even the non-D3 ambit modems are pretty junky though, I have seen my fair share of issues with them when servicing clients. -- Duct tape is like The Force it has a light side and a dark side, and it binds the Universe together
oh, ok. Well my speeds are back up to what they should be (well, not upload speed. That is still on QPSK and at 2.560 Msym/sec). I am still hoping for a DPC3000
