Hello @netnewbie,

Unfortunately the EAP225 cannot join an existing Wifi network as a client (or STAtion).  But, if you buy a second one, you can create a wireless MESH between the one in the yard and one in the house which is connected to your router via Ethernet.

The EAP in the yard (connected via Wireless MESH) can also host Wifi and Ethernet clients simulatenously over the Wifi bridge.

Alternatively, you could buy an outdoor AP, and mount it to the side of your house and set it up with directional antennas pointing into your yard.  Backhaul for this could be Ethernet, MOCA bridge, or PowerLine bridge.

Or something like this Travel Router:

TP-Link AC750 Wireless Portable Nano Travel Router - WiFi Bridge/Range Extender/Access Point/Client Modes, Mobile in Pocket(TL-WR902AC)

@JSchnee21  Thats not correct.  EAP-225 Outdoor is able to connect as Meshing network. I have 3 EAP-225 Outdoor connected as meshing network. You need a recent firmware. The ethernet adapter on the remote Meshing AP can be used to bridge.

Hello @Ronald1965,

You are correct.  But, I believe the OP said that he has only ONE Outdoor 225 -- and no other MESH capable AP's.  He does have a TP Link Router (Tp-link c50), but I'm not sure (I don't think) it can be a root node for the MESH.

@JSchnee21 oh i misunderstood then. 

Dear @R1D2 ,

I want to set up wireless with eap devices in this building.  One flat is 20'x20' and including two rooms. Can be covered with eap mesh? I don't want to use wire. 

Hi @netnewbie,

Could you clarify?  You want to setup Wifi in ONE apartment/condo which consists of two rooms.  Or you want to setup Wifi in the entire building where each "unit" consists of two rooms?

If you are only doing one apartment, as single EAP225V3 should be more than enough.  But it will need to be wired to your router / ISP.

If you want to supply Wifi to the entire building, that is something different entirely, and wireless MESH isn't going to cut it.

@JSchnee21 

I want to gives wifi internet these rooms and opposide side rooms. These wall is about 6" thick.

My distance to that place is about 45 feet. If I will  use 2 eap225 outdoor devices, ok?  Thanks

Hi @netnewbie,

Maybe, but I think it would be a stretch.  Wireless MESH on the 225 only uses 5.8GHz which doesn't carry or penetrate well.  Perhaps if each of the EAPS are next to the window (or outside the window).  The signal is unlikely to go through the outer wall especially if that is block or plaster.  It barely goes through my drywall/studs/insulation/vinyl siding from inside of my house to outside.

Some other options you could consider:

EAP225-Outdoor configured (one per apartment) as a MESH with an EAP225 in the center.  I'm not sure if the 225-Outdoor can be a Master node or whether you need one regular EAP225 (non outdoor) to the master node.

You could mount one EAP225 outdoor for each apartment.  MESH with an EAP225 in the middle, and then run Ethernet from the 225 Outdoor into each apartment and connect the devices inside of the apartment or to another AP.

Alternatively, TP-Link makes long distance devices for point to point links (e.g. CPE510).  You would need 4 of these.  Two in the middle (one pointing to each apartment) and then a receiver on each side.  Then hardwire from these to an AP inside of each apartment.
