WiFi drops internet access for a few seconds then reconnects

[shaunak_96]

I have an ASUS RT-N12D1 router which randomly drops the internet connection for a few seconds. Usually it is not a problem but it causes disconnects when playing online games.
These are the logs during the duration of the disconnect:
Nov 8 17:17:03 start_nat_rules: apply the nat_rules(/tmp/nat_rules_ppp0_eth0)!
Nov 8 17:17:04 wan: finish adding multi routes

Dont know why the log says WAN restored at 11:47 when it is restored shortly after 17:17

Dont seem to find any fixed pattern for disconnects.
