I"m unsure of what you mean by resetting the modem. Try checking the modem settings using control panel. Sounds like a time out or disconnect if idle setting
Im using my parents PC for the time being and have my own profile set up on it. The problem is when I use the internet from this account the connection will fail every 10/15 mins or so and I need to reset the modem. This problem doesn't effect any of the other accounts.
Anyone else had this problem or know of a solution?
