I had some issues connecting with a macbook and one of 2 nexus = 4s. after a reboot of the router both MacBooks connected fine on the = 5GHz radio but none of the nexi connected to either the 2.4GHz nor the = 5GHz radio, instead they produced endless repetitions of: Sat Apr 26 21:27:15 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Sat Apr 26 21:27:29 2014 daemon.info hostapd: sw00: STA = 10:68:3f:4b:0b:48 IEEE 802.11: disassociated Sat Apr 26 21:27:29 2014 daemon.info hostapd: sw00: STA = 10:68:3f:4b:0b:48 IEEE 802.11: authenticated Sat Apr 26 21:27:29 2014 daemon.info hostapd: sw00: STA = 10:68:3f:4b:0b:48 IEEE 802.11: associated (aid 1) Sat Apr 26 21:27:29 2014 daemon.info hostapd: sw00: STA = 10:68:3f:4b:0b:48 WPA: pairwise key handshake completed (RSN) Sat Apr 26 21:27:30 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Sat Apr 26 21:27:33 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Sat Apr 26 21:27:35 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Sat Apr 26 21:27:39 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Sat Apr 26 21:27:47 2014 daemon.warn dnsmasq-dhcp[2560]: no address = range available for DHCP request via sw00 Following Dave's recommendation of issuing a "/etc/init.d/dnsmasq = reload" allowed both phones to connect again, so we might still have a = race hidden somewhere=85 (This is on a system without working ipv6 = currently). 3.10.36-6 looks like it needs a bit more maturation time ;) = It would be interesting to learn whether the same approach might help = other people as well...
