I do computer work on the side to earn extra money. My latest coustomer has 4 computers in their place of buisness and wanted to get dsl and network the four computers to share the connection. Initially they wanted to share the fax line with the dsl service, after checking with their phone service co. rep. who assured me that there would be no problem with this, waiting for the dsl package to arrive and getting the supplies for all the computers(3 lan cards, 12 port dsl/cable router and all the cat 5 cable to make it work the problems started. After hooking everything together I reliazed that there was no dsl signal reaching the dsl modem. After speaking with the dsl supplier troubleshooter on the phone he sent a tech over the next day.they had to run a dedicated dsl line, and then the primary computer quit. The owner of the buis. takes the dead puter to a repair shop there she was told that the dsl signal will fry a mobo unless you are extremely careful with the instalation. I have never heard anything like this before and would appreaciate any info you all can give on this. And thanks in advance.
