Cannot connect 3rd "EAP-225 Outdoor" to my Mesh Network
I'm setting up my 3 EAP-225 Outdoor APs for a Mesh network. I ordered the same time and got one Canadian version and two US versions. The firmware one all three is some what the same but different build number (see attached photo). I downloaded the Omada controller sofware and started configure them. I only had one US version connected to a switch (as per manual) and adopted it as the root AP. I powered up a 2nd unit (not plugged into the switch but wireless only) and the software found it. I adopted it and it connected (this was the 2nd US version). BTW, both US versions are hardware Version 1.8 . The 3rd (Canadian hardware version: 1.1) I tried doing the same way but could not find it in 'pending' or in 'isolated'. Finally just connected it to a switch and then after about 5 minutes, I found it in 'pending'. I adopted it and it connected. But it's connected only by wire. If I try unplugging the CAT5 from the switch, it's no longer connected. So I can't seem to get it to connect to my Mesh network.
I tried downlloading the latest US firmware (1.7.XXXX) but it failed as it said it's the wrong file. I then tried the exact same version (1.5.0) with same build number as the other two US versions and again, it failed as it said it was the wrong file.
Is it because I have Cnadaian firmeware on it that I can't connect to the Mesh network (where I have two US versions)? If so, why can't I update the firmware to US versions? What can I do to make this work? Pleasee be detailed as this stuff does not come easy to me. Thanks very much.
