iPhone Can you prevent connecting to a specific wifi network

If you look at the network settings under WiFi it says that it will automatically join a known network. I don't think it's possible, not even on Android.

You could remove that network from your list, don't know if that's a good solution for you.

 

I think you'll need to "Forget This Network" after each time you legitimately join it, and are finished.

 

I could be off on this, but once you are on a WiFi network and go to WiFi settings on your iOS device, there should be a little blue "i" in a circle icon next to a WiFi network you joined, if you tap that you should get settings related to that particular WiFi network, and there are often things like auto-join and/or auto-login there--perhaps if you disable those it would do what you want?

 

I read this a little different I think.

WiFi network info is shared between devices. Once you connect on one, the rest of your iCloud logged in devices are aware of the association and make use of it. Looks to me like he wants this feature normally but in this one spot with just his phone he wants the phone to be unaware of the network and not try to join.

I can't think of a way to do this other than to tell you to turn your wifi off on your phone at the office or join the network. The wifi login credential sharing is a global setting between your devices.

I think even if there were an app for this, the GPS fencing would be more taxing on the battery than the wifi trying to join. (GPS fencing because you could in theory use an app to know you're at the office but iOS does not allow this) My bigger issue would be no data on the phone so no updates while in the office. right?
