iPhone XR WiFi problem

[kagzer]

I have a weird problem with my XR.
Wifi connection is on, device is connected in theory, Fing app can search for other devices, but no any real connection.
If I turn WiFi off and on, problem solved, but it’s just on surface.
After a while it occurs again.
I am after resetting network setting, 13.4 was installed with iTunes in DFU mode (then I restored from iCloud backup).
Any other devices work well (2 more iPhones, 2 Watches, etc)
Router is TP-Link Archer C6. (I do it think the problem is there...)

Sorry for bad English 🙂

I have the same problem with the same phone and the same router. There are 2 other iPhones having this issue in my family and the router is the same, Archer C6.

So far I've not found any router setting to stop this. I've tried almost every possible wifi related setting combination on the router.

Sometimes it says it's connected with full bars, but from the router end, it doesn't even have an IP address and it won't switch to 4G either. Renewing the IP from the iPhone does not work, only toggling wifi off and back on again.


If you find the solution please message me or post here about it.
