Telephone Calls and Internet BLOCKED by WiFi

[mc5w]

A female friend at the 100 unit apartment building where we live is frustrated
because her Android telephone will NOT work here. When I call her her Android
rings and when she answers I can hear her voice over my Sprint phone for about 2 seconds and then the call cuts off and her phone then reads, "Blocked by WiFi," or "No WiFi." She thinks that because our apartment if filled with WiFi access nodes that she should get WiFi. She does not understand why her telephone says, "No WiFi."

I have tried to explain to her that ALL of the WiFi here is PRIVATE and that her telephone is NOT allowed to use it. She does not understand the difference between public and private WiFi. The Android DOES NOT KNOW THIS either which is why when I was at Carnegie-Mellon University we liked to say that a Feature was a euphemism for a designed-in-BUG! She will not let me tell that she needs to turn off the WiFi transceiver.

If your telephone does not work in an area that has WiFi nodes either all the nodes are private or the telephone is locking onto a private WiFi node. Just turn off the WiFi and try again. That will force the phone to use the telephone and Internet channels on a PUBLIC cellular tower.

This why I have stuck with the Sanyo SCP-2400. Also, the touchscreen keys on an Android are too small for my fingers what I need for a smartphone is on the 8.5x11 inches.

It does not help that my female friend has a very low frustration tolerance i.e. she has GROUCH Syndrome.

Simple issue is to turn off calls by wifi and use the phones own antenna.

That was what I wrote.

I also forgot that digital cellular telephones are inherently Internet Protocol Version 6 devices and almost all if not all WiFi only understands IPv4. For smart phone telephony over WiFi the telephone needs to use a protocol for sending IPv6 over IPv4 such as Isatap. Most of the public WiFi here in Columbus, Ohio such as at the library or SC Wash & Tan operates through NAT/PT ( Network Address Translator / Port Translation ) which means that a protocol for operating over NAT/PT such as 6a44 or Teredo needs to be used. The reason why you can make outgoing telephone calls over WiFi but not receive calls is because NAT/PT and firewalls act as 1-way street.

No. That is not what you wrote. You wrote to turn off WiFi. I wrote turn off the setting for WiFi calling. You go into the advanced calling settings and turn off calls over wifi. What that does is make the phone ignore wifi when available. It won't matter if wifi is active, the phone will ignore it.
