Dual band router mystery

I can see but not connect to one of the bands on my dual band wireless router. But I know that band works, because I can connect to it with a different computer.
I just set up a D-Link DIR-825 B1 wireless router. It broadcasts on both 2.4 GHz (b, g, n) and 5 GHz (a and n) bands. I've got each band set up as its own SSID. My old spare computer can only see the 2.4 band, which is expected, as its wireless card only supports 802.11a, b, and g. It connects to the 2.4 just fine.
My primary computer, which has a wireless card that supports 802.11a, b, g, and draft n, can see both bands. And it connects to the 5 GHz band without a problem. But it absolutely refuses to connect to the 2.4 GHz band, even if I delete the 5 GHz one as an okayed SSID.
Any thoughts? FWIW, the problem PC is a Compaq 6515b running XP SP3.

Best answer: Is the 2.4Ghz band on the router configured to use WPA2 security, or something labelled "WPA/WPA2"? I've noticed that some 802.11n clients have problems connecting to routers configured as WPA/WPA2. I think it's related to only WPA2 being allowed by the N spec.
