Just had a brief heavy cloudburst (heavy, heavy rain) and it was fun to see the neighboring 2.4Ghz WiFi AP's disappear in WiFi explorer (Mac app similar to InSSIDer)...
Wish I would have captured a screencast - next time perhaps...
Was fun to see all the 2.4GHz, which normally there's quite a few just above the threshold, just disappear...
Also notice - the two Airport Extreme AC's (they're just AP's) along with the very stable DirecTV Wireless Video bridge - brought to you by Cisco-Linksys and Quantenna...
(The Wireless Video Bridge is just basically an AP with a MOCA and Ethernet connection - in my LAN, it's all VLAN'ed out along with the other non-trusted boxes, but the WVB has been amazingly stable, and yes, it's agile in the 5GHz space, it likes DFS channels, and jumps around quite often)
