Adding 240AC to existing network without using ethernet cable

[dposmondsr7367]

I have nine 240AC in a network that are all on POE connections to a Cisco switch which is fiber attached to a Cisco Firepower 1120.  I need to add another 240AC where there is not an ethernet connection.  I have a power injector.  The question is how to I add the new 240AC wirelessly to the network?  I have read that this is possible, but I cannot find a set of steps unless this is not possible.

  - @dposmondsr7367                You can only connect it to the others using a mesh setup ; start with looking at

@dposmondsr7367 

u cant add a Cisco 240AC AP wirelessly as a mesh/repeater in this setup,this APs require a wired uplink (PoE or injector) to join WLC..

if u need wireless extension, u will need a mesh-capable model (e.g., Cisco Mesh APs) or run eth cable to new location

https://www.cisco.com/c/nl_nl/support/docs/smb/wireless/CB-Wireless-Mesh/1768-tzep-Cisco-Business-Introduces-Wireless-Mesh-Networking.html     (unfortunately Dutch version)

both mention 240AC as mesh capable.
prerequisite: you need a minimum ios version!
With firmware version 10.4.1.0 or earlier, your CBW 140AC, 145AC, and 240AC APs could only be used as Primary Capable, Root APs. Starting with firmware update 10.6.1.0 and moving forward, there is a new option to configure an Access Point as a Mesh Extender.

[dposmondsr7367]

I am running 10.10.1.0. Is there a link to steps to have the one 240AC connect wirelessly to the nearby 240AC that is wired?

[pieterh]

you need to connect the "remote" AP temporarily to the wired network, so it can join your existing primary AP

what other steps are you missing in the document ?
https://www.cisco.com/c/en/us/support/docs/smb/wireless/CB-Wireless-Mesh/kmgmt-3144-cbw-mesh-role-selection.html

Step 1
Make sure you have the latest version of firmware running on your CBW mesh network. Click the links above to download the latest firmware for your APs. Click if you would like step-by-step instructions on doing a firmware update.

Step 2
Log into the Web UI of your CBW Primary AP. Click on the light green arrows in the upper right-hand corner of the Web User Interface (UI) to enter Expert View.

Step 3
Navigate to Wireless Settings > Access Points.

Step 4
In this example, you will see the CBW240 AP and a CBW140 AP configured for mesh. Both APs have the role of Root. We will be changing the CBW140AC from Root to Mesh.

Step 5
Click the edit icon. A pop-up window opens. Click the drop-down menu under AP Role and select Mesh. Click Apply. At this point, the AP will reboot. This will take several minutes. Just a friendly reminder that you will need firmware version 10.6.1.0 or above and you will also need to be in Expert Mode instead of General for these options.

Step 6
After the reboot:

1. The AP joins the Primary AP
2. The change will be reflected in the Access Points table with the CBW140 AP Type labeled as Mesh Extender and the AP Role has changed to Mesh.
3. The AP is still connected to the local LAN where the AP was originally installed
4. Mesh Extenders use the 5Ghz band for the Mesh Backhaul by default, but you can use 2.4Ghz as well.

So, this means my entire network is now mesh even though the Master 240AC and other 240ACs are connected to the network via hardwire?

[dposmondsr7367]

The 10th 240AC is now hardwired (last one listed) The next steps you listed will change the Primary AP to mesh or only the last AP listed so it can be an extender?

[pieterh]

We will be changing the CBW140AC from Root to Mesh.

-> you are only changing a single AP to mesh, other existing AP's are unchanged!
    choose the AP you want to use as mesh AP.
    after configuring it needs to reboot ,
    that is the time to disconnect the wire and it will setup a wireless connection to the root AP

Here is what I see, confirming 10.10.1.0

[cid:d18c4c60-db7c-419d-8cbf-e00096beffd3]
When I edit the past 240AC listed
[cid:e7392cdb-e77a-4375-8286-cad762584262]
There is nothing in the dropdown for operating mode. Do not see an option to set this one AP in mesh.
There is this option
[cid:2ac65575-de56-4a2c-86d6-70630c10cd51]
I will try this option when the network can be cycled

your post seems garbled, I guess you tried to include some images, but they do not show.

dit you execute step 2 ?
Step 2
Log into the Web UI of your CBW Primary AP. Click on the light green arrows in the upper right-hand corner of the Web User Interface (UI) to enter Expert View.

[dposmondsr7367]

I did, attached is the screen shots in a word document.  

[pieterh]

the option you show in the word document needs to be set first, as described in prerequisite-2

Prerequisites

1. Only Primary Capable APs (CBW140AC, CBW145AC, CBW240AC) are allowed to change from a Primary Capable AP role to a Mesh Extender role.
2. Your CBW deployment needs to be in mesh mode.
