I have a mesh network using 3 Omada 245's and one Omada 225 in my home all on ethernet backbone.

I would like to extend wifi coverage to my garage as the signal from the nearest Omada 245 starts to drop off and the smart device connected to it keeps dioconnecting.  I have been offered by a friend a single CPE-210. I appreciate these are primarily used as a pair for line of sight connection but I belive they can also be used in other modes?? Can one CPE-210 be used as a wifi repeaterand will it connect to my existing mesh network?

As a last resort I could an ethernet connection to the garage but it would have to be in exterior grade ethernet cable and if I can get away with a wifi link this would be easier to install.

Also if set up as a wfi repeater can you connect a device such as a PC to the ethernet port as well?
