Best way to use a network expander?

I had a very slow connection to one of my WCO units.
I bought the TP-Link AX1500 WiFi Extender Internet Booster, WiFi 6 Range Extender Covers up to 1500 sq.ft.

I first connected my base station directly to the ethernet port and there was no real improvement.
I then switched the connection on the base unit from ethernet to the wireless connection from the TPLink. It was even worse.

Is there a way I should do this that will solve my connection issues?

Everything is on 2.4ghz

Thank you!

The WCO will connect directly to the base station, not your network. I would suggest getting a base station as close to the camera as possible. You may need multiple bases to cover your entire area. You can check the signal strength of the base to camera connection in the Wyze app by selecting your base station on the homepage.
