I am trying to set up a point-to-point wireless bridge using CPE510.

Everything works fine except for one thing. The issue is that when encryption is enabled, the devices fail to connect.

Even when the two devices are directly facing each other, they still do not connect, so it seems like it's not a distance or interference problem. Of course, when encryption is disabled(It means "Security Mode" is set as None), the connection is established immediately.

An interesting point is that when I repeatedly power cycle the devices, they sometimes connect, but this is very rare.

I have tried various methods like disabling DFS channels, turning off MAXtream, and so on, but the issue persists.

I found a forum thread with a similar problem.

What should I do?
Thank you.
