Reboot N150 router remotely

As you discovered, I don't believe there is one.

I went through your manual to the places I thought were appropriate, searched for (re)start (re)boot and reset, and looked at the index, but nothing.

I suspect that unless you get it through a firmware upgrade, you are out of luck. As a side note, what a glaring omission on Netgear's part. Really inexcusable.

A tricky workaround: Go to 'Backup Settings' then 'Save a Copy of Current Settings' then restore your settings from the file (netgear.cfg) The router will restart after restore :)

Yes. You need to enable remote administration; Choose a single IP address you will be accessing it from and then you will have full access to the router remotely. Good luck!
