Cannot connect Iphone XR to RBR40

[JArcher]

Hi,

    I have an Iphone XR that cannot connect to an Orbi AC2200 - just tries to connect and it would not connect and would not give any errors.   I have multiple devices that I can sucessfully connect (other apple iphones).     I have the latest firmware for the orbi products (V2.2.1.210), plus the latest ios for the iphone (12.1.3)  Curious thing is that I am able to connect other wifi networks.  I have tried restoring from strach the iphone, resetting network settings, restoring from a backup and nothing helps - sometimes it connects but it does not give any errors but there is not internet conectivity.   Of course on the ORBI side I have restarted the routers , checked connections.  Any suggestions ?

Thanks for your help !

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
What WPA security modes are you using? Try WPA2 and AES only.

Try disabling the following and see:
IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).
Be sure the BeamForming and MIMO are enabled.

Sort of points at the Iphone XR as the source of the problem. Your router does not care about what you throw at it.

What happens when you try to connect? Any error messages?

Has the phone ever worked on Orbi? Was the iOS recently updated?

Hi F,

      Thanks for your response !

      Great suggestions , I tried them all and still the Iphone XR takes a long time to connect, and if it does if does not have internet (while other devices connected do)

 Regarding your questions :

1) What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz. ==> Tried all combinations.   It seems the problem is on the 5ghz band .. that is were the phone is trying to connect
2) Any Wifi Neighbors near by? If so, how many?  Not many and I had tried when other WIFI are not avalable , so that does not seem like the issue
3) What WPA security modes are you using? Try WPA2 and AES only.==> This is the one I normally use

4) Try disabling the following and see:
IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

Be sure the BeamForming and MIMO are enabled.

==> tried all those settings to ...

Thank you for your suggestions

Advanced Wireless Settings both 2.4GHz and 5GHz changed CTS/RTS Threshold to 2307. Changed preamble modes to long or short
