Just updated to 1.5.2 Build 20260113 rel.53105(5553) firmware version, and while laptops, tablets, other wifi devices appear to be back online following router reboot, my ecobee thermostat wifi is having issues. IP address is default range 169.254.255.x and it does not pick up Gateway or DNS addresses via DHCP.

What's up?? Please advise. Not a major problem, I just can't see weather info at a glance thanks to lack of internet. 

UPDATE: For whatever reason, after a few hours the issue appears to have fixed itself, and the thermostat is again able to phone home for weather information. No config or other changes made on ir or my wifi beyond the router firmware update. Problem "solved". ¯\_(ツ)_/¯
