WIFI up, device connected but no internet

wow, I have been having the same issue for a week
l was frustrated about not knowing why my wifi wasn´t connecting to the internet. wired devices had no issue to connect to the net.

this one line "option igmp_snooping ‘1’" on network.config solved all the problem
i don´t know what it does, it works! .....THX!

My Vlan config:

config interface 'lan0'
	option force_link '1'
	option proto 'static'
	option netmask '255.255.255.0'
	option type 'bridge'
	option ipaddr '10.10.11.1'
	option _orig_ifname 'eth1.2'
	option _orig_bridge 'true'
	option ifname 'eth1.2'
	option delegate '0'

config interface 'lan10'
	option proto 'static'
	option ifname 'eth1.3'
	option ipaddr '192.168.10.1'
	option netmask '255.255.255.0'
	option delegate '0'
	option type 'bridge'
	**option igmp_snooping ‘1’**

config interface 'DMZ'
	option proto 'static'
	option ifname 'eth1.4'
	option ipaddr '11.11.11.1'
	option netmask '255.255.255.0'
	option delegate '0'
