Have you checked your new router to see what default rules are enabled
there?
The router firewall is disabled. (I have a another router serving as a
firewall between it and the modem.) Besides, all hosts are on the local
side of the new router, and disabling the Windows firewall eliminates
the problem.

If it works when you disable the firewall, then (to state the obvious,

So far so good.
I would suggest to examine all of the rules carefully. I say this
because it is happened to me before, and I could have sworn that I
looked at all of the rules.
I've looked at
Advanced Settings; Incoming Rules
and I've looked at the output of
netsh advfirewall firewall show rule name=all
What else is there to look at in Windows 7 Home?
This is doubly frustrating because Cygwin sshd has been running properly
for 10 years on one of these computers and 8 years on the other. Perhaps
I should reset the firewalls to default, but that will break other things.

I've had weird instances where the Windows Firewall tools lied; I
confirmed this by temporarily shutting down the Windows Firewall
entirely, then restarting the service having problems and retesting.
On retest, it worked fine, confirming it was the firewall causing the
problem.
I didn't have to restart sshd; I could connect as soon as I disabled
Windows Firewall.
What exactly the problem was varied (this has happened many many times
to me)... In some cases it was the rule definition for the scope not
matching the actual network, in some cases I could not find any real
issue, but deleting and recreating the rules fixed the issue, in a few
cases, I also found a deny rule that somehow matched the service
having problems, and deny rules take precedence over allow rules. One
example of the conflict could be "sshd allowed" vs "port 22 denied";
the deny would take precedence.
I don't see any way to set port rules in Windows 7 Home, and none are
visible in the list of incoming rules.
I could not delete sshd, only disable it, even as administrator. (The
delete button was grayed out). I disabled it, rebooted, then enabled
it. That didn't help.
