WiFi not working in OpenWrt. What to do?

Question

WiFi

After about 3-4 minutes, if you try to connect via waffle, then there are messages in the log

daemon.info dnsmasq-dhcp[17214]: DHCPDISCOVER(br-lan) f0:f6:1c:xx:xx:xx
daemon.info dnsmasq-dhcp[17214]: DHCPOFFER(br-lan) 192.168.1.3 f0:f6:1c:xx:xx:xx
