wpa doesn't work w/the dlink DWL-G630 card though I suspect it's the card's fault.

Returned for another brand's router and card. Disabling ssid broadcast works, ie, the ssid is hidden. And wpa works very for a few hours straight so far.

And here's a quick note regarding the problems some people seem to have connecting this device to the Internet via their Cable or DSL modem. It seems that the WAN port is configured out of the box to be locked in at 100 Mbps. This is where the problem comes from. The vast majority of Cable and DSL modems out there operate at 10Mbps per second only. Uh-oh! Bad move D-Link! Because if you plug the router into the modem out of the box and you have a 10Mbps modem you won't be able to connect the devices and you won't be able to go online. Very dumb move D-Link. I bet tons of routers have been returned for service just because of this simple and fixable issue.

This is easily corrected by logging into the router and going to the "Tools" menu and then choosing "Misc". Scroll to the middle of the page and find "WAN select to 10/100 Mbps" and select 10Mbps and click APPLY. Once the router reboots, your router and Cable or DSL modem will be working happily together and all is good. But there really is no reason that this device should be shipping with 100Mbps switched on by default. I hope that future firmware revisions will correct this issue so more novice users can easily setup this great router without issue.

Otherwise, a very good purchase and very good piece of equipment for anyone who is looking for an affordable and reliable WiFi router. Highly recommended.
