R9000 60GHZ Bridge mode

Hi, Friends in the community!

 

We are doing some practical measurement in university.

We recently bought two R9000 router to make a test on it!

 

Unfortunately, we were not able to bridge one of them in 60 GHZ!

 

We realized it can be configured in bridge mode just in 2.4GHz or 5 GHz, which is strange for us.

 

Now I was wondering if there a way to make changes and fix it on 60GHz  or should we return the products?

 

Best Regards
