You using the SAME SSID for both units, then if so,  on the iPad FORGET the network, should fix it.

 

Suspect some data from the old setup is saved and used for the new one if the SSID is the same?

Thanks for your reply but no SSID are different for both units.

I have zero problems with my iPad Pro 2018 model? Nor with my iPhone 12 Pro.

 

I've switched routers at least 3 times on them, an A20 X55 Mesh, and now an AX55 which is also an AX3000.

 

Only things I could be thinking might be a cause is:

 

• S S I D Channel is not one that the iPad can work with (DFS?)?
• iPad not close enough to the router?
• Too much interference?
• I've never found on the Apple Store a W i f i  S S I D channel display (name can't be used it seems) that showed me S S I  D's and the channels, but you could find one maybe and see if that sees it? Even using the phone?
• Possible Security problem, test with NONE on 5Ghz?

 

Works for me?

 

Do you see and other 5Ghz S S I D's?

 

Now that I think about it, you are connecting to the router/gateway.

 

I assume you ARE connected to the LAN though, if you have an IP Address of 169.254.64.175 I'd assume you do?

 

So, it is then that the iPad does CONNECT, but says no Internet Access? If so, I'd be looking at the router/F T T H that might not be allowing Internet access?

 

(had to use blanks to get past the 'censors' here)

SOLVED!

A friend of mine owner of a computer store sent me an Archer AX50 that he had on display. And you know what? IT WORKED OUT OF THE BOX! Of course I sent payment right away.
I can only figure out that something happened when I did a firmware update of the router. So, as soon as I have time I will see how to rollback to a previous firmware version.

Thanks @IrvSp for your responses.
