|Thanks for the several good ideas. Since last post have:|
1) Run from an Administrator Command Prompt (DOS) box: netsh int ip reset.
2) Run from an Administrator Command Prompt (DOS) box: netsh winsock reset.
3) Bypassed everything (Vonage box, Netgear wireless router, Linksys switch) with direct Ethernet Cat5 from the cable modem to this one (Vista) computer only.
and the problem persists :( still rebooting roughly twice a day...
