[Cerowrt-devel] Issues with 5ghz after a couple of days' uptime

[Aaron Wood]

As a contra-datapoint:

4d uptime here, but without any ipv6.  A couple GB of data, both
WAN<->internal, and between 5GHz devices (pushing to an AppleTV).  No real
traffic between 2.4 and 5GHz, though.

WPA2 on all interfaces (babel and guest interfaces are disabled).
