Bad Gateway on Startup?

[MikalE]

I fired up my T500 this morning and the internet connection would not connect to the internet via the wireless router.

All of my other systems and the TV were running along just fine. I used the troubleshooter to find out what was bad, and this usually fixes just about everything.

Except this time, it reported that the router gateway was bad. How can that be when everything else was running along just fine?

The T500 was connected to the router, but could not access the internet.

I went into the modem/router configuration page and rebooted the router and that solved the problem.

What I don't understand is what would cause this to begin with?
