I have three EAP615's, hooked up to a TL-SG2008P v1.0 and one (1) of them is all of a sudden stuck in adopting.

The config of all three is the same, but for the name and location, I don't understand the how and why, anyone?

Mainly because the other two are working without a hitch....

I have read about the EAP225 havin similar issues, but that is a diffferent system all together, also all the suggestions made in those threads are not applicable.
