We have a Win2000 Dell computer with a 3Com network adapter factory installed. We have attempted to connect to a DSL line, however are told by the phone company that our connection won’t work because of a conflict between the 3Com adapter and the DSL. They suggest that we replace the 3Com adapter with another network card. We were able to connect to the DSL for several weeks and are now unable to do so. We can connect another pc and/or laptop from the same workstation connection, but ours won’t work. Any suggestions.
