Maybe you would have to take it apart and see how the antenna are connected. Many times these devices have antenna connected with the same connectors a laptop card uses. Then again you may have to unsolder the antenna.
This unit appears to have low power output around 25db, the legal maximum is 30db and many devices run at 29db. You may be better off getting a unit that has more output power from the factory.
You could just build your own repeater. Get a directional client-bridge from say ubiquiti and hook it to a quality ap or router running as a AP. This would greatly reduce the penalty you pay for using repeaters because you would be using different radios to talk to the main router as you use to talk to the end machines.
I would also consider powerline devices with a remote AP before a repeater. A repeater should only be used as a last option when any type of connection is better than no connection.
Let me preface this my saying I am not a network guy. I have a basic understanding of some of it.The cable router is in the basement in one end of the house and everything else is on the ground level in the middle or far end of the house except the printer. We are going to have a ring doorbell and some ring floodlights over the garage. If I put an access point up stairs I would need a radial antenna to cover the whole upper level of the house, wouldn't I?
Would the access point wirelessly connect to the cable router?
Do I need a Client-bridge, an antenna, and an access point?
I hope I am not asking too many questions. I am just not familiar with this hardware.
