cable modem (?) question

Hello all...

Whenever I don't use my computer for about an hour, I always have to shut down / restart to get it to go to my default web page, or to enter outlook. It never used to do this before; it's almost as if it has to reboot to wake it up. Is there a simple setting i could try to make the machine on-line all the time without rebooting after moderate periods of inactivity?

Thanks in advance folks.

 

You should give your isp a call, sounds like an error on their end.

to temporarily fix it without reboot try start/run/winipcfg

Hit the release all button, then the renew all
