Turn on SNMP on your router plugged into the adsl modem and use a tool like mrtg to graph the circuit utilization. Also, access your adsl modem's error counters and find out what your signal to noise ratio is, what your received decibel level is, if your taking errors, and such. Some of the consumer modems do not have these counters accessible and can only be queried via the DSLAM operator. Your service provider is right to push the problem back to you because it almost certainly is not their network. If it was their network you would notice a definite change at different time of days - if they are overloaded then at 4:00am you should get lightning speed. If your DSL sucks at that time then it's your problem, not their network. Unfortunately for you, however, your service provider didn't explain to you what you need to do to properly troubleshoot this. It could possibly be that you ASSUMED the problem was their network and pissed them off when you called in. I would suggest you call them again, politely, and ask, not demand, that they check signal levels and error counters on your phone line. If they can't do this then have them refer you to the telco that can. One other piece of advice for you, if your goal is to "prove" the ISP is wrong then you ought to just find another ISP. Your goal should be to find out the cause of the slowness, not in assessing blame. If your using a consumer ISP it is likely the first level tech support people probably cannot help you since their main job is helping people fix their misguided PC desktops, and they usually aren't even allowed to touch the back end equipment. But they can in fact hurt you badly by simply not passing you to the upper-level tech people who could help you. So, be nice to them.
