That is why I am not keen on a system restore, it took a long time to fix the modem it had to be restored to original settings and it took an age to connect it to the computer as it would not recognise the modem.
not sure what happened but I was trying to reset the security settings as my daughters I pod Touch woild not connect because it was WEP incoded (and it appears that the ipod touch does not like WEP) , then it all went haywire.
That is how I disconected the sound drivers instead of the modem drivers.
Anyhow all is working fine on that side now so you can see my reluctence.
