Resolved iPhones suddenly no longer finding home Wi-Fi

[r2shyyou]

Within the past 45 minutes or so, both my wife's 4S and mine are no longer finding our home Wi-Fi.

The Wi-Fi is via Time Capsule (3rd gen, I think) and the network is protected and not hidden.

Both of our 4Ss were connected to Wi-Fi just previous to this (and forever and a day before then) without issue.

The Mac on which I'm writing this is successfully connected.

Our Apple TV is successfully connected.

I've never had this issue and can't think of what it could be.

The Time Capsule has been rebooted both physically and via AirPort Utility, the phones have been rebooted, and both the TC and phones are up-to-date software-wise.

Anyone know what the issue could be? Thanks.

Fixed! Following a cohort's suggestion, I removed the network security, which rebooted the TC, and the network showed up. Then I secured it again, which again rebooted the TC, and I was good to go (to bed, finally)!
