The cable run is <100 ft, and I am using a power injector that I have moved while testing in my office and the other building to make sure it wasn't the issue.
The IAP is far enough away from the other APs that it can't mesh.
Excellent question about the AP being able to be reached by IP and getting info from the UI. Since the ENET light was green, I assumed all was good on the networking side. Apparenlty not. The AP does not show up in the management console. I have no idea why that would be. What next? Should I assign it a static IP when it is connected to the management console and then move it to the remote location again?
