When I joined the local ADSL co. before half a year I baught a new 2Wire modem-router and conected it to the main computer through the telephone line while I conected the other computer at my house which is located at lower floor to the telephone line (the same line ofcurse). Then I configured the settings of the modem-router and WHALLA! fast internet connection on both computers in my house for a fair price – paying just for one internet account!
