Just ran into a bit of instability today on my WRT3200ACM after being up for 3d 4h on Divested-WRT SNAPSHOT r17276+9-b1bff5cb57.
I noticed the issue first on my phone - specifically, my phone would be connected to the WIFI (5 Ghz AC), but no data would load from any IP address. I thought it might be a DNS issue at first, but I couldn't even pull up Luci by hitting 192.168.1.1. Phone just sat there spinning.
The fix was easy - simply disconnected from the WIFI network on my phone and reconnected. Issue resolved.
Not sure what's causing this "hang". The logs seem pretty clean, and my laptop has continued to operate all day with a VPN connected.
Another device (a wifi-connected sensor, connected to 2.4Ghz N) seemed to have connection issues at the same time, and simply restarting it (to reconnect) fixed the issue.
Anyone else seeing a similar issue?
