After about 30 minutes my 56K modem stops communicating but nothing locks up. Also, it won't hangup until a reboot (can hear it over the telephone).
Other tips:
* have tried 2 different modems.
* have tried 2 different browsers.
* have checked modem settings & see nothing suspicious.
* have checked for adware, viruses - nothing.
* no firewall.
Running Windows XP pro sp2.
Thinking it's something in XP, just not sure what.
Thanks in advance for any suggestions.
