Wifi issues

[robl45]

I've been having major wifi connection issues since getting this car where it will tell me to check dhcp settings. Sometimes it will connect after turning the wifi back off and on again, most of the time it requires rebooting the touch screen to get it to connect. I see this most when going into reverse or drive and connecting my wifi hotspot. Anyone have a solution for this?

Tesla is essentially washing their hands of this saying that wifi is not supposed to be connected while driving.

Yes they are correct. The car is not configured to use wifi when driving. For a long time wifi would not work when you put the car in gear. It was just a short time ago that you are able to reconnect. But like it or not, that's normal.

Same issues here, wifi router right near the front door with the car parked on the driveway.

My wifi connects and I get the little green tick but after about 20 seconds I get the 'check DCHP server settings' prompt. I will happily go into my router/internet settings but what am I actually 'checking'? Does anyone know what this needs to be? I have a BT Smart Hub.

Mine does that most times but it is connected for me.

What's the BT Smart Hub have to do with the WiFi connection?

Here's some troubleshooting help:

It should just ask for the password and connect, I do get the random messages but usually it seems to be connected.

No, you don't need to do that. The settings are proper if it works with your phone.

What that means is that the messages are getting dropped due to weak signal / weak antenna on the Tesla. How far from the door is your car?

I'm not saying this is incorrect, but I get this message when connecting to my phone hotspot that is in the car with me.

If you have a dual band router and the 5ghz signal is weak where you park your car, the car seems to stick to the unusable 5ghz signal, I had that problem, in the router settings if you have the option for band steering set your model 3 as 2.4ghz only, see if that helps

 

[robl45]

On my router at least there are two different networks for 5ghz and the lower one

Router DCHP settings are fine by default otherwise the internet would not work for anyone. Every device printer, phone, computer, laptop, etc uses it and it is only the Tesla that ever says this.

I have been facing an issue in our MY where the wifi name does not show up list.any pointers on this ?

I have the same issue- my Tesla S can list my neighbours wifi but not my bthub. Frustrating - it used to work. I had the charger upgrade…

If you have WPA3 enabled, try disabling it to see if it helps. Both my Tesla and Wall Connector have problems with WPA3.

As others have indicated, if you can configure your WiFi so your car will only connect to the 2.4 your issues will likely go away.
I turned the 5g off on my WiFi extender I setup for our cars and have not had an issue since.

The 3:s must have a sucky WiFi antenna! I can walk around my whole backyard with great reception on my iPhone but need to park my car right up to my house to make it work. And even then it’s barely one bar.. Strange.
