I have a Power Mac G5 and I have 1mps broadband and I use an ADSL modem connected via USB. The problem is every so often it just freezes and disconnects for no apparent reason and the only way I can reconnect is to pull the USB plug out then putting it back in then connecting again. It cant be anything to do with my ISP because (a) I changed it from 512kps and to a new ISP about 2 months ago and it was the same then and (b) it doesn’t do it on my old ibook G3 it never disconnects. I’m guessing it must be something I have to change of configure on my G5. Please can anyone give me some advice, i'm going mad!!!
