New Pc.Tell her to use the Ethernet Connection.That should connect immediately without any discs.And if it does not connect immediately switch off Modem for 10 seconds then back on.It should then be connected Ok.
Yep, a big problem....don't go there! Get the model and download the drivers...You will also need the NTL software (Your friend may have to contact them for a replacement CD if he / she has lost the original)
I use a model 250 cable modem with an ethernet lead (it takes USB as well), and have twice had to re-install my computer since having it. It has not been necessary to load drivers. The disc that they gave me originally just put loads of unnecessary stuff on my computer and has not been used on either re-installation. You do however need to configure OE of course. To facilitate this we save/export our account configurations onto a disc/usb stick which makes it simple if it needs doing.
