Why doesn't iPhone switch to cellular when network down at home or office?
I have no problem using cellular when I leave either but if in location where normally connect via Wifi to LAN an on to internet if either the internet goes down or the LAN goes down I need to turn off Wifi to start using Cellular.
Make sense?
Maybe I've goofed in the Settings.
Thanks for any suggestions.
iPhone XS
When you say you phone doesn't switch over to cellular when the Internet goes down, is your router still broadcasting a signal but no Internet?
If that's the case, then no, it won't switch over when the router can't get Internet but it still broadcasting. It will switch when it it losses the WiFi signal.

Clear the Caches:
Clear "Other":
Clear the storage named "Other". It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time: How to Clear "Other" in your iPhone's Storage - Use Backup - User Tips. Caches would be being used for remembrance of application use.

More on Clearing the Caches:
I'm not so certain of the ultimate solution. However, when it comes to an application, a cache is the latest-created snapshot of preferences that were caught (pre se) So, that's what resetting the caches does -- it rids of accidental settings in applications, and sets them to how they are in fact set in the application's preferences. So, give it a go.
Thank you. When I turned off the Network Router (but not the Switch), then it switched to cellular.
Hmmmm..... So, I gather that the iPhone isn't smart enough to know when the internet is down if the LAN is up. Correct?
I appreciate the answer and the education.
No, the phone just looks for the WiFi signal. It's not a matter of being smart, it would have to do a lot of extra work to constantly monitor if their was Internet on an active WiFi signal. That could burn up bandwidth and battery.
Understand. Thanks very much.
And I followed your instructions without a) incurring the wrath of my wife if she lost internet on her computer or b) failing to find the correct black box in our network rack. I'll let you guess which was more important. ;) LOL
She would have just rolled her eyes..... Again. ;) LOL
Since the start of this post, I've found the problem. I should say our network guy remotely figured out that our power conditioning unit was not supplying consistent electricity. When I took that device out of the chain and replaced with just a power strip all was back to working 24/7. Now I have a new WattBox incoming.
Thanks again for your help. I appreciate.

Are you sure this is the problem and the easiest solution.
Thanks very much.
Thank you.
I'll try again with LAN down but I believe it still tried to connect via network/wift and did not switch to cellular unless I turned off Wifi in Settings.
Try this, while you have a good working Internet connection on WiFi, unplug your router and see if it automatically switches to cell.
Your welcome. Glad you didn't upset the Mrs!
So the next step would be to contact the company that supplies your WiFi and have them troubleshoot why it's going down so often.
You're welcome. Glad to hear you got it figured out.
