with v29, air link worked without issue; even on a 10 year old laptop (970m) running wifi5 through the same router. With v30, 31, and 31ptc air link will connect for at most one minute, usually just seconds, before jumping back to the quest 2 Home Screen with WiFi showing as disconnected and several of the UI apps lagging or unresponsive. The WiFi then resets after about 30 seconds. On the rare occasion I can stay connected for a minute, the oculus debug tool shows my lag is maintained at 30-40ms with very few frame drops.
