I have 2 pc's networked with a crossover cable. all has been well with internet sharing and file & printer sharing until I have changed to ntl's cable broadband. Now the itnternet sharing will not work and I think I've tried every change of setting to try and get it to work. The modem is USB and also has a rj45 socket . will I have toi get a network hub or switch to get it to work or has anybody got any suggestions that may get me online on both again.
