I won't bore you with the technical details but suffice to say that in order for the "signal" from VM to get to you and get through all the bits inbetween, it needs a certain amount of power to do it. Think of it as pushing a bowling bowl down the lane and having to hit a series of pins every meter. Every time it hits something it is going to slow down a bit so you need to make sure it starts off fast enough so it has enough oompf to reach the end. As the signal from VM gets closer and closer to you it loses power and in an ideal world it gets to you with just the right amount which is why I said your downsteam power levels (what you get from VM) should be as close to 0 as possible. Conversely, your upstream power is how much power you need to send back the signal so that will start off high and then go down as it gets closer to VM's end. There is such a thing as too much or not enough which is why your downstream power can be a + or - figure. There are limits within which your signal is deemed acceptable and yours is outside of those which is why your connection is dropping and you are getting those T3 timeouts in your error log.
You need to ring tech support and tell them that you are experiencing intermittent connectivity issues which you believe are due to out of spec power levels. If you get a good agent he will ask if he can log into your pc remotely so he can connect to the shub and have a look at the same pages which I asked you to do. If you get a ming mong they won't understand what you are saying and will go through the palaver of rebooting your shub, resetting it to factory settings and mucking about with other stuff (like changing your wireless settings). No matter what they say they have done, they cannot change any settings on the shub which will fix things nor can they do anything their end. If they turn around and say "madam I have just send a signal to the modem and I have changed the power settings and I can see that the problem is fixed now" they are lying.
Not all the connections in the street cabinet (what your house is connected to) are the same because properties are situated at varying distances from the cabinet. Depending how far or how close you are to the cabinet means you might need a little bit more or less power. Your connection needs to be moved to a different tap point so your downstream power goes up by +10 (to make it +3) and your upstream comes down by -10 to make it +45. You don't need to feel bad about ringing them up and don't think you are a pain in the bum. The tech who brought the shub round should have checked your power levels before he left so all of this is his fault for doing half a job. You are actually doing them a favour by making their job easier because you know what the problem is. If India muck you about be firm with them and tell them you want a tech booked and if they say no then ring back go through to retentions and complain. If you don't get back to us before the tech comes out you should know he will do one of two things; he will either move your tap point in the cabinet or cheat and put an attenuator on the back of the shub which will adjust the power coming down the cable before to reaches the shub.
