i was trying to update my iphone 7 plus to latest ios 12 version but the download and install option in "software update" was greyed out . The error that kept popping up was "Try after connecting to WLAN", depsite being connected to WLAN successfully. I tried resrating device , reconnecting to Wifi, switching off "WLAN assist" but none of them worked.

As you can see, if you have a computer available updating via iTunes is an option.
Remove and download the iOS update again
If you still can't install the latest version of iOS, try downloading the update again:
- Go to Settings > General > iPhone Storage.
- Find the iOS update in the list of apps.
- Tap the iOS update, then tap Delete Update.
- Go to Settings > General > Software Update and download the latest iOS update.
If you don’t see the update in the list of apps or if the issue happens again, you need to update your device with iTunes.
