Hi Neil, Will look up info about codes when I have time.
meanwhile the fact that you are having the same problems on 2 computers SUGGESTS that the problem should be external. Well you are using 2 different modems aren't you ! ? I have to pose these questions :- 1. Do you have call waiting turned off. ? ( Dial #43# on your phone ) 2. Do you have any phones across your line while you are using the computer. ( Memory phones can drag power from the line and cause disconnects ) 3. Do you have a mobile phone ( switched on ) or TV set sitting near your computer ? ( Known to sometimes cause problems ) 4. Does your phone line ever have clicks or noise ( buzz, hum ) on line ? Bob Neil Houghton wrote: > Just to update on progress so far.
