I have win xp home, about 2 weeks ago this started. I have no problem connecting to the internet, however after while web pages will not open, and i will just get the page that states page unavailable (as if i was not connected) I will check for mail, and it will tell me i am not connected. Icon shows i am connected. ( i have dial-up). The only way i can reconnect at that time is to shut down computer and restart. I cannot just click icon to disconnect, wont work. Ocassionally along with this i will get the error msg box telling me that US Robotics (modem) has encountered a problem and needs to shut down. Ever since i had this modem installed it has done this occasionally, but now it is really bad. I contacted isp, they had me check settings, told me to contact USRobotics, they are no help. Online chat with hp last night they dont know? Might this be a modem problem, a connection problem, a virus?????? I have current spyware and AV up to date. Any Ideas would be appreciated.
