I just have this issue on one of my three wndr3800 routers, maybe because of the way they connect via wan? The one having this issue has dhcp client modus WAN to a cable modem, the others just have static IP. I also noticed IPv6 lease time is always 24h regardless what number you put in the configs, 12h, 31d which just affects IPv4 lease.

After 26h the router is in this "broken state" again, clients dont get IP via DHCP (getting ip... auth failure). restarting dnsmasq doesnt do anything /etc/init.d/dnsmasq restart. Only rebooting the router solves it for a while. Theres nothing in logread about this.

It seems the problem is wifi, restarting wifi solves it and clients get IP. My wifi config:

config wifi-device 'radio0'
	option type 'mac80211'
	option path 'pci0000:00/0000:00:11.0'
	list ht_capab 'SHORT-GI-40'
	list ht_capab 'TX-STBC'
	list ht_capab 'RX-STBC1'
	list ht_capab 'DSSS_CCK-40'
	option txpower '17'
	option country 'DE'
	option hwmode '11g'
	option distance '20'
	option channel '11'

config wifi-iface
	option device 'radio0'
	option mode 'ap'
	option encryption 'psk2+ccmp'
	option key '...'
	option ssid '...'
	option network 'lan'
