Wifi

[FredL]

I have a 2020 RX 450h. I have the wifi on and a subscription with AT&T. Often, when I turn on the car, the wifi does not start and I have to go through the process of connecting to the provider. Is there a fix for this problem? So far, the dealer doesn't have any answers.

Let me guess... You are using an Iphone as the hotspot?

I have the same thing with my Android phone (not sure if it's the phone OR the operating system updates) with my older Pixel 5 this used to work seemlessly, however this has always been a problem with the Pixel 7.

I suspect that this due to the phone picking a random MAC[1] addresss for the wifi and the cars list of networks uses the MAC address rather than the network name to connect. I have found that sharing an internet hotspot over Bluetooth doesn't suffer from the same issue and always connects.

I believe iPhones also use random MAC addresses?

[1] MAC address stands for Medium Access Control address historically a six byte id for a network card burned in at production time. The first three bytes are the manufacturer code (OUI) issued by the IEEE, the other three bytes are a serial number. I still have the Sage Mainlan one burned into my memory 00 80 2c from when I worked on the network hardware over 30 years ago.
