Since my D-link DI-614+ died, I've replaced it with a Linksys WRT54GL
router. I had an external D-link AN24 antenna on my old router. The
antenna has a cable with an N connector and a (reversed?) SMC connector
and the latter one connected with the router.

Now my new Linksys WRT54GL has a reversed TNC connector. Can I use my
old external antenna after replacing the SMC connector with a TNC
connector or are the antenna's with different types of connectors
inherently different?
