I upgraded my modem from 28.8 to 33.6 and have seen little difference in connect speed. My all time high has been 28,800. We just recently installed a second line and since then I have dropped in speed. Average speed now is 19 to 21 and highest has been 24. My husband has a computer also and this morning he hooked up to the second line and I used the main line. We dialed up at the same moment, I connected at 26,400 and he connected at 21,400. I have been averaging 19,600 most of the time on the new line. I am curious as to why the drop in speed. It all has something to do with the telephone lines I am sure. Just recently I had a connection problem and my server suggested it might be the phone lines. A technician came out and checked the lines and found no problem. At that time he told us that the phone company is responsible for voice communications only and not concerned with data communications.
