Far more likely, you're experiencing a network config issue with your laptops.

I would suggest that you erase your current network settings on one laptop, and reconfigure the laptop's network settings. You can probably start by directly connecting the laptop via ethernet to make sure the router is routing traffic via the ethernet.

After that, attempt to set up the wireless again.

I don't think that's likely since A) I hadn't touched the configuration in the time between when it was working and stopped working, and B) they BOTH have croaked at the same time. Something took them both out.

The ethernet via CAT5 works perfectly.
