Today I tried to log onto the internet and it wouldn't come up. So i reset my modem, and it still didn't come up. I unplugged and reconnected everything and it still didn't come up. I went into the next room and internet's working fine, so it's not the connection. Could my modem have finally died? The thing's about 6 years old. Also, I notice that every 5 or so seconds, an alert bubble pops up and says I don't have a firewall protection and then quickly disappears. Has anybody out there seen a similar problem before?
