I just bought and installed a new ASUS RT-AC68U wireless router and it works very well for most devices on my home network but others experience Internet outages at random intervals of time. I haven't had any such on Debian 7.2 and IOS 7 but this happens several times a day on Windows 7 and 8 as well as on Android 4.3. The router is configured to assign static IP addresses via DHCP based on MAC address. One of the devices that experiences this problem has IP address 192.168.1.4. It runs Windows 7 and this is what I can see in the router log when it looses Internet connection:

Dec 24 19:38:27 miniupnpd[3315]: recv (state0): Connection reset by peer
Dec 24 19:38:27 miniupnpd[3315]: HTTP Connection from 192.168.1.4 closed unexpectedly
Dec 24 20:33:46 miniupnpd[3315]: Expired NAT-PMP mapping port 1224 UDP removed
Dec 24 20:33:46 miniupnpd[3315]: Expired NAT-PMP mapping port 1224 TCP removed
Dec 24 21:58:38 miniupnpd[3315]: sendto(udp): Operation not permitted

Any idea why this happens and how to fix it?

EDIT: I get these mystical entries in the router log too:

Dec 25 01:36:27 kernel: br0: received packet on eth2 with own address as source address
Dec 25 01:37:03 kernel: br0: received packet on eth1 with own address as source address
Dec 25 01:38:00 kernel: br0: received packet on eth2 with own address as source address
Dec 25 01:41:39 kernel: br0: received packet on eth1 with own address as source address
Dec 25 01:42:16 kernel: br0: received packet on eth2 with own address as source address

First plug in to the internet directly and run off of that for awhile. Make absolutely sure in your own mind that it's not your ISP dropping out from time to time.

Then get another router. They don't cost that much relative to debug time which has the probability of success of about zero. I've seen very funky wifi routers that drop funny packets at random times.

regarding kernel: br0: received packet on eth1 with own address as source address try disabling NAT acceleration under LAN>Switch Control and also try different SSID names for 2.4 and 5Ghz wifi
