Yes, the 5GHz radio on the ENH700EXT does have the option to set the
operation mode to Client Bridge.

However, only 1 radio at a time can be set to Client Bridge/Client Router
mode. For example the 2.4GHz radio on the ENH700EXT is set to Client

the 5GHz radio to Client Bridge will not be available and vice versa.
