Namless Wlan Network in „known Networks“ on iPhone 13

You may try some of these steps, please check after each step...

It seems like there might be an issue with your device's network settings or the way it's handling previously connected networks. Here are some steps you can try to resolve the problem:

1. First, try to forget the "nameless wlan Network" that keeps appearing. Go to your device's Wi-Fi settings, locate the network in question, and select "Forget" or "Remove" to remove it from the list of known networks.
2. Since the mysterious network appeared after connecting to Seat Cupra infotainment via Bluetooth, there might be some residual data causing the issue. Clear your device's Bluetooth connection history by going to the Bluetooth settings and removing any previously paired devices. Be connected with CUPRA CONNECT or SEAT car connectivity with the wireless full link
3. If the issue persists despite trying the above steps, it's possible that there is a more specific problem with your device. Reach out to the manufacturer's support or visit an authorized service center for further assistance. CUPRA owners | Bluetooth compatibility manual
4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
5. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
6. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
