WiFi calling and VPN not available on Weak Security network

[DaveTheRave]

As I type this message I'm at a local indoor pool club that has no cellular connection indoors. However they have free WiFi. My iPhone 6s (iOS 14.5.1) tells me that it has "Weak Security" (WPA/WPA2 TKIP). When connected my phone does not fall back onto WiFi calling, like it does at other places with good wifi (home etc).

I also noticed that my VPN app will not connect, which means I cannot use the internet at all unless I disable the VPN (add the weak security network to my trusted Wifi networks).

Anyone know why this WiFi network doesn't let me use these features? The pool is at a country club, could their network be designed to prevent this kind of usage? Curious how this works. Thanks.

More likely a misconfiguration than a willful block.

For AT&T WiFi calling (and conceivably others) their router must have IPSEC passthrough enabled, as WiFi calling establishes a VPN.

Here's some info from the AT&T web site. Is there someone at the pool club you can pass this info to?

Thanks for the info. I'm only there once a week for a half-hour or so for a kid's swim lesson. There's no IT contact that I know of and I'm sure the swim teachers want nothing to do with the tech stuff.
