As a contra-datapoint:

4d uptime = here, but without any ipv6. =A0A couple GB of data, both WAN<->intern= al, and between 5GHz devices (pushing to an AppleTV). =A0No real traffic be= tween 2.4 and 5GHz, though.

WPA2 on all interfaces (babel and guest interfaces are disab= led).

are you using WPA?

taking a long term packet capture seems worthwhile.
