Adding A5x to existing A5c-omni tower - how to migrate clinets


i have old A5c-omni tower and it is not doing well (just very slow). I want to add A5x (60deg) for some of A5c clients.

How do I migrate clients? 2.5 client will not connect to 2.9 new A5x sector and if I do A5x upgrade first it will not connect to A5c…

Will they connect to each other in interop mode? Do I need to setup both A5c and A5x on same SSID for the time of upgrading firmware?

So it is connecting in interop

Interop mode should work, FYI Mimosa warns about issues, but I have had a few occasions where my techs used the wrong firmware and stuff connected. (Note: we never left it running for very long that way, just a couple minutes and we did an immediate update)

What we have been doing is visiting the customer’s house and realigning their antennas then doing the update. That has worked out pretty well for us.

To do an upgrade like this, you can use Wifi interop mode on the A5x for the clients to connect. Upgrade each client and then you’ll be good to go.

I am now approaching this same issue - and I have to Say that the Wifi interop method works.

Kinda a pain as I have to: put up the gear(N5-45x2) / check my aiming / confirm what clients will be benefited by moving to it and see if I can hit new clients.

I do plan on using a different SSID

As I will be leaving my A5c up there as well; running in Wifi interop mode means that I have to pick a totally different channel as SRS will not be available.

When I have all my old clients moved / then I can move to SRS mode - and that requires a reboot.

Worth it? You bet - soaking an A5c with 45 clients is going to drag it down, so by migrating some off to an A5x I should be able to pick up some new clients and get under the 44 mark for the A5c.

This would be a really good job for an A6x! - But alas you can not get them yet! Soon I hope!

Now, I just have to confirm the number of subscribers (max) for the A5x (in SRS) - is it 44 still?

Let me know, if you know!

To add to this - my method that I tested is:

  1. Log into an existing client that is on old AP that I want to move.
    a. Select the new SSID
    b. Wait for it to connect to the new AP.
  2. Login to the (newly) moved client. (AP is in Wifi interop mode) - Client has no network access - but I can reach the radio ( tested with and
  3. Update the firmware on the client radio to 2.9.0.
    a. Once it reboots client should have network access again.
  4. Do steps 1 through 3 for all other clients that I want to migrate.
  5. Reboot into SRS mode.
  6. Sit by the phone and watch it “not” ring (fingers crossed).
