New Modem...Well Maybe.

[Micjones]

So my Motorola modem, courtesy of AT&T, shot craps last night.
I got up, called them and was pleasantly greeted with news that it was freshly out of warranty.
Much to my chagrin, I went and bought a new one on my lunch hour.

I get home from work...And what do you know...the old one's working again.

I know I can take the newly-purchased modem back to Best Buy, but will they take the 2-year protection plan I bought for it back?

I'm almost wary of the "all is well" old modem though.
Suppose this is just an intermittent functional spell?

Thoughts?
