Iphone 17 failed to connect Guest Wi-FI

[jaseemtt]

iPhone 17 fails to connect to the guest Wi-Fi (PSK)when it comes within range of an AP250, but it connects without any issues when it is within range of an AP410C. what could be the problem if anyone know this. I have manually set similar working AP (AP410C)channel and channel width to non working but no luck. only iPhone 17 fails and iPhone 15, 16 works.

Sounds like an AP250-specific compatibility or firmware issue rather than the PSK itself, especially since the same iPhone 17 works on the AP410C. I’d compare the AP250’s firmware, radio/security settings, and client logs against the working AP410C; updating the AP250 firmware would be my first step.

That sounds like it could be a compatibility issue rather than a configuration problem, especially since only the iPhone 17 is affected and other devices connect normally. Besides checking the channel settings, I'd also compare the firmware version running on the AP250 with the AP410C and verify whether there are any differences in WPA settings, PMF (Protected Management Frames), 802.11r/k/v, or Wi-Fi 6-related features. It would also be helpful to capture the association logs on the AP250 to see exactly where the authentication process is failing. That should provide a much clearer indication of whether it's a client compatibility issue or an access point configuration problem.

I’m facing a strange issue. An iPhone 17 fails to connect to the guest Wi-Fi (PSK) when it comes within range of an AP250, but it connects without any issues when it is within range of an AP410C.

What could be the problem if anyone knows this? I have manually set a similar working AP (AP410C) channel and channel width to the non-working one, but no luck. Only the iPhone 17 fails, while iPhone 15 and 16 work perfectly fine.

This is getting frustrating because I was trying to access some study resources on csssyllabus.com.pk through the guest network, and it just won't load on this specific access point. Any technical insights on what might be causing this specific device-AP mismatch?

This sounds like a device-specific compatibility issue. Have you checked for firmware differences between the AP250 and AP410C, or tried changing the security mode (WPA2/WPA3) on the AP250? It may also be worth disabling band steering or 5GHz temporarily to see if the iPhone 17 connects more reliably. Futbol Libre
