Another comment contradicting the above recommendation (nothing personal), it is actually not worth buying a new standalone access point unless you can install specifically OpenBSD on it, and temporary reuse of an old access point is sub-optimal now matter what you (re)flash on it, most firmwares including third party are vulnerable and suffer from the same reliability and hardware limitations. With the right cable (proper impedance and connectors on both ends, many shops provide various length conveniently) you can place your antenna (sector panel for indoor use is better in corners) some distance away from the (mini)PCI(e) device in your router, and still benefit from OpenBSD without relying on low quality (old) standalone access points (which often contain a very outdated and quite frequently exploitable version of Linux with a web interface on top). As previously said, the wireless device in the OpenBSD is your best chance of reliably functional setup (and the chance to learn this with OpenBSD instead of relying on a crippled external device, one more thing to worry about battery backed operation / POE (power over Ethernet)).
