After the 5.1.7 upgrade, the portal option with facebook check in liberates an option "FACEBOOK WIFI V2" that allow user to configure the instagram log in for wifi connection. I've already set the sugested parameters on my facebook and Instagram pages, but i'm still receiveing the same screen with only facebook check-in option. I've even disabled the option Facebook Wifi V1, but when i try to connect, gave me the message tha my EAP is not compatible with "face Wifi V2" or its firmware is out of date. I've checked both options, the EAPs are updated and their versions are on the compatibility list on TP-Link's web site. Please help.
