May not be the case, but this isn't unlikely... When they first provisioned his modem, presumably after he got it installed, they pushed the "right" configuration file. Overnight, their system may have checked his modem and for some reason, pushed the wrong configuration file. I've had something similar happen and others have indicated it's happened to them. What happened was I upgraded my speed and the rep provisioned the modem while I was on the phone. Do a speed test and all looks well. Overnight, the system pushes back the old configuration (as if it's not aware that I upgraded speed ). In fact, at that time, if you owned your own modem, you could access the modem's internal webserver and see the config data and that's how I caught that they re-provisioned it incorrectly.
Hence my query about him being able to view the stats/config. That would be quite useful here.
