Hi,
I will report this to our RnD department and see if it's possible to test the issue.
In the meantime, could you give me more detail how did you try to connect them? Was there any specific encryption used, what is the hashing, and so on, just basic connection details.
Also, you could include troubleshoot file, which can be exported through System > Adminsitration > Troubleshoot page. Just keep in mind to download it after you've tried connecting and after the router rejects the connection, so it would be possible to see the issue in the logs. Send the file to me via private message.
