NVR and wifi module - struggling to connect camera over multibridge

Hi everyone.

Short version here - I have an NVR S4 max running in my shed - I have the POE cameras attached, all working perfectly.
I am trying to bring in E330 pro wired solo cams into the NVR via the wifi module plugin but so far the range is limited to mere metres.

From my understanding, I should be able to place the camera anywhere in the mesh wifi network I have across the property and it will pull the stream into it. It doesn’t seem to work via multi-bridge.

Details of network below.

Ive got a fairly expansive property and I’m trying to get coverage across as much as I can.

My setup looks like this.

4G modem

Oc200 hardware controller

Outdoor range extender to another outdoor range extender that then runs to an indoor range extender

I run a cable down to a poe switch which the nvr then plugs into.

All works very well. Good signal coverage from wifi and my series of e330 professional cams work fine across the mesh network when connected to HB3

I want to put the e330 cams on the monitor with my POE cams so I bought the eufy wifi module but it’s not giving me any usable range and even though it says connected via multi bridge, it doesn’t seem to be working.

Any help would be amazing!
