I just set up my new EAP225-Outdoor AP last night.  Got through the initial setup items using the web interface, went outside to check connection and could connect, but a note under connection status said "no internet available".

It was given an IP address by the router and I was able to configure it with a laptop on the network so it would seem everything is working other than the lack of internet connection.  I was also able to log into the AP's web interface as well as devices within my home network using my phone (wifi connected to the AP) outside.

Upon further investigation (checking my connection status on my main router) I noticed it was blocked, so allowed it (I have MAC filtering set up to allow only recognized devices) and saved.  Now I have internet access.  Oddly it showed up as a wired device - apparently the router sees the phone as wired because it is connecting through the AP which is wired.

Anyway, I saw several others who had similar issues so thought I would post this as it might help them to gain internet access, if they have things in their router set up similar to mine.
