Just in case anyone else is trying this with this router: there seems to
be an intermittent firmware problem affecting this and other products.

I had been trying without success to get this router working with
Freeradius. I had figured out that the Freeradius certificate scripts
had a problem with signing, and finally found a modified Makefile that
signed client certificates with the root certificate (what were they
thinking of, not to do this originally? How could it ever have worked
with EAP-TLS?). I loaded the appropriate files onto the test client, and
spent the next hour trying to figure out why the WRV210 was making no
contact with the Freeradius server. I could see the details of the
server were correct, and I had certainly been seeing contact during my
last session on this problem. My client was associating with the router,
then failing to authenticate. Not a byte was arriving at the Radius server.

By chance, I came across this, about a completely different product:

Out of curiosity, I opened the same page on the WRV210, clicked Save,
and suddenly it burst into life, my Freeradius debug log started
scrolling wildly up the screen. The certificates were now OK, and I had
connectivity.

Back in May, a man from Cisco had tried WPA2-Enterprise on the WAP2000,
and it had worked for him, so therefore the Cisco user was wrong. Well,
I've managed to reproduce exactly the same fault on a completely
different, though related, product.
