On Google+ (https://plus.google.com/110340962945642622580/posts/NJ3NyiQMasK), I said:

After several years of flawless operation, my D-link Dir-632 router has needed a reboot 3 times in the last 24 hours. It's losing internet access.
It's not possible that it's Comcast, is it? Since a reboot of the router fixes it immediately?
A check of the D-link site shows one firmware update last July. So that can't be it.
Curious.

It certainly could be Comcast, if their network loses track of the fact that your router is connected. If neighbors aren't having the same problem, though, it's more likely your router.

Ok! well, then I think I have a nice explain for last night's disconnect... it was windows update night. And my connection went down around the default update time for the west coast...

Good to know. If no more reboots are needed today or soon, I'm going to declare it fixed ;)
