If anyone is interested in how reselect.interval is affecting wireless connection, this is what I found in my log connecting two Wi-FI ac AP using v7.16rc4:
MAC.ADD@Bridge-WLAN: AP changed channel to 5660/ac/Ceee
MAC.ADD@Bridge-WLAN: disconnected, reason code 8, signal -84
- 2/4min later -
MAC.ADD@Bridge-WLAN: connected on 5660/ac/Ceee, signal -74
MAC.ADD@Bridge-WLAN: authorized, signal -74
