Hi everyone,
I have an iPhone 13 that I got about a week ago, transferred from an iPhone 11 (using the temporary iCloud backup). Since then, I have a recurring Wi-Fi problem at home only.
Device details
- iPhone 13, iOS 27.2, but the problem was also there on the previous version.
- Model number: MLDU3CH/A
The Wi-Fi menu is labelled “WLAN” instead of “Wi-Fi”, and the “Known Networks” list is labelled “Réseau connu” in French. The phone also asks me, for each app, “Allow [app] to use wireless data?” (WLAN and data / WLAN only / Don’t allow), which I understand is normal behavior on China-region iPhones. My Region is set to France in Language & Region.
Symptoms
- When I get home, the iPhone either asks for the password again and says “incorrect password” (even though it’s correct), or it seems to connect for about one second, then fails (“no internet” / no blue check mark).
- It happens on both my home Wi-Fi networks : the main box network and the repeater network.
- My PC and other devices connect to the same network with no problem. The iPhone also connects fine to my school’s Wi-Fi (a captive portal), every morning.
- Resetting network settings fixes it immediately, and everything works perfectly. Then the problem comes back after I leave home and return.
Home network
- SFR Box 8 (fiber) with a Wi-Fi repeater
- Security protocol: Mixed WPA2/WPA-PSK, AES encryption (the only other option offered is Mixed WPA3-SAE/WPA2-PSK)
- Wi-Fi 6, 5 GHz at 80 MHz
- MAC filtering is disabled; the iPhone appears in the connected-devices list on the box when it works
What I’ve already tried
- Forget the network, restart the iPhone, re-enter the password
- Reset Network Settings (this is what works, temporarily)
- Private Wi-Fi Address: changed from “Rotating” to “Fixed”
- Turned off “Wi-Fi Assist” / Use Connectivity Assist
- Restarted the box and the repeater
- Turned Wi-Fi off when leaving school and back on at home, to rule out the school’s captive portal. The problem still happened.
- Airplane mode on and off
- Checked for configuration profiles: there was a Proton VPN configuration (never connected successfully), I disconnected and deleted the app.
- Contacted Apple Support by phone: they couldn’t solve it and suggested erasing the iPhone and restoring it.
Questions
- Has anyone seen Wi-Fi settings getting corrupted or reset after a transfer from another iPhone?
- Could this be related to the regional/”WLAN” firmware, for example unsupported Wi-Fi channels with this box?
- Is there anything other than a full erase that I could try?
