Wifi connectivity issues with NEW MCU

[Goofykiller]

I updated to 10.6 (new MCU) and no longer can reboot no matter how long I press the scroll wheel buttons.

same here

the service center just updated me that even the 2018.12 firmware didn't fix my wifi issue. damn it,

Update from service center. He tried all firmware, it didn't solve the WiFi issue. He said Tesla has updated it to highest priority, but maybe it's a hardware issue, then it will cause a recall on all cars.

FYI,
SC fixed the issue of not being able to reboot the New MCU with the scroll wheels by doing something they called a “12 volt pull”
(They said any SC would know what that means) It worked! Apparently the latest firmware.

Full details here:

Ok - Long Post Ahead.
Hopefully this is all new info that will help.
Picked up my new MS 100D today with new MCU and 7 miles on the odometer.
Car was close to perfect.
Zero issues until I attempted to drive away.
I had just paired my phone.
My foot touched the brake inadvertently. A message appeared on the IC indicating that service was required and something about Stearing Assistance being limited. I put it in drive. No power steering. Eventually the message cleared and the power steering worked again, however, oddly my phone was no longer paired, as if I never added it.
They pulled it out of the delivery area into the service drive.
Here’s what they did for me and a few things I learned.
First they fixed the issue of not being able to reboot the MCU with the scroll wheels by doing something they called a “12 volt pull”
(They said any SC would know what that means) It worked! Apparently the latest firmware does not resolve this issue.
There was an update waiting to be installed that they deleted from the car because a newer version was available. Then loaded 10.12 5eadc71.
They informed me that there is another bug (Drive Rail) that caused the loss of power steering and that latest firmware does not fix this either. So here’s what caused it. The door was opened when I pressed the brake. They said to be careful make certain that the door is closed and my seat belt is buckled before pressing the brake. Apparently, engineers are working on both issues.
I was unable to test AP as I only drove it 17 miles to the shop where it’s getting wrapped (SunTek Ultra + 2 coats of Gyeon Quartz G2 MOHS). It will take at least a week :-(
I do like the new navigation voice and IC views (see attached image)

My friend who traded in his previous Tesla warned me that having Tesla is like having Windows OS, one update breaks the other.
Oh, I forgot Tesla is Linux

I’m so glad to have joined, our first Tesla S 100D has the WiFi, sound and reboot issues. I thought it was just us. I feel better knowing I can track the resolution here.

Thanks for all the very helpful information. Love our new Tesla and this forum.

Any updates? I have the new MCU and had many of these issues on 2018.10.6, took to a service center where they did a hard reset and everything was resolved. I could even reboot with scroll wheels. Then I updated to 2018.10.12 and now I'm having all the same issues again and cannot reboot with the scroll wheels like before.

Welcome to the Tesla community. After a few drives in your new MS, you'll never want to drive an ICE car again! Congrats.
I also just got a new MS 100D and having all same issues. I had an 85D for the last 3 years on lease. This will get fixed... just requires some patience. The new AP and Maps are large improvements vs. the prior versions.

After posting that our new S100D would not connect to the internet nor identify any wi-fi, this morning it was asking for the wi-fi password, connected after entry of the password and reconnected on my return home. Interestingly its still on 2018.10.6.

I might try the reset but not sure I want to spoil a good thing. The only change here is the temperature has increased but no other changes.

I just tried the reset and it worked, very surprised since it did not work after numerous attempts previously. I know I'm new at this but holding two buttons is within my abilities, I wonder what changed given the software version is still unchanged?

New MCU?
March 2018 build?

March 2018 build but I have not been able to confirm it has the new MCU. Vin ends in 243649, does that help?

I'm trying to learn but still drinking from the Tesla fire hose, some of you have a 6 year head start!

Daniellane,

Thanks for the information. I’ll give that a try.

My Tesla said it will update software tonight, interested to see how it works. Estimated 1:40 minutes.

Now I’m hesitant to download the update offered, though driving a 2017 AP2 Model S

 

[Jfassino]

It only took about 40 minutes for the new update 2018 14 4d, I tried the reset and it work. Still connecting to our wi-fi after the update. Thanks to Daniellane I confirmed we have the new MCU.

Now our Tesla app lets us open the frunk and open and close the trunk. It also looks like the map shows the status of super chargers when they are displayed on the map. I don’t recall seeing the icon with the stalls occupied and in unused.

So 2018.4 fixes the resetting the MCU with the scroll wheels on the steering wheel?

 

[Jfassino]

Before the version update the connectivity and the reset started working. Still workin on both counts after the update.

I updated this morning to 2018.14 and can confirm that it resolved both issues

I got 2018.14 last night. I can now connect to my home WiFi. I was also able to hold the scroll wheel buttons to restart as my car was unresponsive earlier today.
