Installing better Wifi Card in Router?

[SOLVED] Wi-Fi cards and the AP mode

I occasionally build or upgrade OpenWrt routers. Sometimes, this involves adding wireless capability to a device that previously was wired-only. So every now and then, I need to source a Wi-Fi card. The question, of course is, what do I buy that will work for my purpose? Specifically, is there any easy way to check (before buying) whether a particular model of W-Fi card supports the access point (AP) mode? If not general, then perhaps manufacturer-specific? There are some easy no answers to this…
