No connectivity?

No connectivity?

Yesterday my Tesla Model 3 shows no connectivity for the cell signal to the car. The bars have a line through them. It is not a matter of being in a place where there is poor signal, I have tried it around town in various locations that I have had strong signal before. Any thoughts on how to fix?

First thought would be try rebooting.

M3BlueGeorgia | 4 January, 2019

Agree with M8B.

Good opportunity to learn how to do a simple reboot.

CharleyBC | 4 January, 2019

Had that in OR. It started in a remote area, so I didn't think anything of it, but it continued into a largish city, where we were stopping for a Supercharge. I rebooted, and cell signal was back.

jerrykham | 4 January, 2019

We get this all the time on our Model 3. Our Model S never has the problem. For us, we are at the very fringe of AT&T service (I don't know why; it is a suburb area). We actually had to leave AT&T for our cell phones as the signal in the house was basically non-existent although it was one bar outside. In our garage, where the Model 3 and Model S both park, we put in a Wi-Fi router just for them and they have great Wi-Fi. It seems like the Model 3 though turns off Wi-Fi when it goes into its sleep mode while the Model S does not. So if the Model 3 sits in the garage for more than a few hours it tries to wake and use LTE first (and can't). After a bit it hits some sort of re-try threshold and just gives up - and WILL NEVER RETRY until the MCU is rebooted. We've tried to do nothing to fix it and it will stay with no LTE connection for at least a week. But if we reboot it in a place with any signal at all it will start working again. And, if we go on a trip (last one was four nights) it works the entire time with no problem. But as soon as it stays overnight in our garage we have to reboot to get connected again. Every time. And again never with the Model S that sits right next to it.

I think I'm seeing something like this as well. Model 3, delivered just a month ago.
We have a sometimes-weak AT&T cellular signal at our house (somewhat rural).
It's been working fine for the Model 3, though, until I got the recent 2018.48.12.1 update around Christmas or so.
Since then, a couple of times (like right now), I try to use the Tesla app from in the house and the the icon just spins with the "Waking up..." state... It just can't wake up the car via the app.

Yesterday, when it happened, I went out to the car and there was something on the scrreen that implied it had no network connectivity. So I turned on my cell phone's hotspot, and connected the car to it by touching the LTE thing on the screen, and the car searched for and found my phone's hotspot. Then, when I turned off the hotspot, it found and used the LTE connection again. But it's done it again today. Obviously, I don't KNOW it's the 48.12.1 update that has adjusted the behavior, but it's only happened since that. I kinda suspect there may be an update to fix this at some point...

LTE in model X keeps flashing on and off. Did a restart multiple times

cholmes82000 | 18 May, 2019

My Model 3 has been doing that pretty routinely. When I start the car there is no connectivity but within a few minutes it will come on. I have no idea why. The only problem it causes is being forced to listen to the regular radio instead of chosen music.

gwang.unm | 4 June, 2019

I am having the same problem today. it is the first time.
bluetooth works but no cellular connection.

Kary993 | 4 June, 2019

Plenty of other threads outlining this issue, particularly for me with 2019.12.1.2. There does not seem to be a consistent remedy to this issue.

wcfalcon | 8 August, 2019

Just purchased my model 3 July 30 and the cellular has never worked and I have wait 2 weeks to get the local service department to look at it - AND they want to charge me $87 to run diagnostics!!!! I will not pay!

FISHEV | 8 August, 2019

Which Model 3 to you have? How did it get delivered without cellular working? Maps, music, Tesla's Virtual Technician, the iPhone remote controls...a lot depends on the cell connection. I thought they used to sell without "Connectivity" but even those had the cell connection it just was for car needs like Virtual Tech and iPhone controls uses did have satellite maps or music.

wcfalcon | 9 August, 2019

@FISHEV - I have the dual motor, LR AWD. We didn't notice the cell being out because on delivery the first thing i did was setup the wi-fi. Only when I was driving around that evening did I notice the maps weren't working while I was streaming music via my phone (I use plex)

JPinNC | 17 August, 2019

My M3 just started behaving like this this week (Dual Motor, LR AWD). Seems to have trouble transitioning from WiFi in the garage to cellular when leaving. Reboot while driving seems to work...after several minutes. I have had my M3 since mid-June. Other that 1 other time I can recall where it lost cellular connectivity while out and about, It's been rock solid.

kooldude123 | 28 August, 2019

i have the same problem but only when leave a basement parking area ... i get no signal for next half an hour and then it starts by itself

RICKSTOKES57 | 4 October, 2019

Massive issues with WiFi to cellular handoff from underground parking. Very frustrating. It usually takes at least 10 minutes to connect, rebooting seems to help at times. For many short trips I make, I am without connectivity for the whole time. I hope this gets resolved soon.

fried | 13 October, 2019

Same problem here in the UK. Got my M3 about a month ago and it worked fine the first couple of weeks. Just did the latest update but still no LTE connectivity. Most annoyingly, when searching for a new destination, you can't enter into the usual search field. A new window opens asking for Street, City, Country. This needs to be precise otherwise it won't find anything.

gami1996 | 11 December, 2019

Same issue in Houston. Car is parked outside where AT&T signal on a handset is 2-3 bars but every night my M3 loses its LTE connection and it takes about a mile and 5 minutes of driving (I’m in a dense residential area) until LTE kicks in. I think there’s a strong correlation to cold weather.

sbfuller | 22 December, 2019

I have the exact same issue. As soon as I leave wifi it shows the cross line through the LTE signal strength indicator. My subscription for maps etc recently renewed after the one year free period so I thought for some reason that was the problem. Also my voice command does not work. I tried downloading the app again. I’ve tried rebooting. The problem still persists. It also seems to have happened just when we got a deep freeze outside. I made a service appt but it won’t happen until Jan 7 2020 and I have to drive an hour to the service center. I’m bummed. Does anybody have a solution??

Pg3ibew | 22 December, 2019

I was just having issues with the web browser in the car I did a reboot All is fine nw

rdm227 | 8 January, 2020

I've had the issue of losing LTE connectivity once I go into my parking garage at work and when I come out will not reacquire it the entire 45 minute drive home. Soft reboot does nothing. Will usually have to wait a while after getting home before it will come back again if I go out. Extremely frustrating. Does anyone know a solution?

ReadyKW | 8 January, 2020

I had intermittent problems with LTE connectivity back in October then stopped working completely. I took the car in to SC and they installed a new "connectivity" board, no problem since.

adcock.dan | 8 January, 2020

Complaint on the Forum seems to have been the fix. The problem has not occurred again since my post. It was not the LTE signal. I had three or four bars every time and phone worked.
These mobile computers can really fray nerves sometimes!

g.donovan | 13 January, 2020

Has anyone had recurrence of the LTE issue? Ours stopped working after ~2 months (M3), was fixed at the SC (software fix only), and now has happened again after another ~2 months. Called in to service and the issue is under "technical review"...

billroger | 13 January, 2020

Is it possible to download Tesla updates from WiFi in Tesla Repair center to a 32BG flash drive and upload/install in vehicle later??

Tronguy | 13 January, 2020

@billroger: Never heard of anybody successfully pulling something like that off. Far as I guess, I get the impression that Tesla servers know perfectly well the name, MAC address, serial number, VIN, etc. of the car and won't download software to anything other than a proper target. Laptops with USB drives are likely not invited for all sorts of good reasons, the biggest being security.
I wouldn't be surprised that there's people at a Tesla SC that can put a jump drive with a load into a car, but there's a reasonable suspicion that that action has security stuff all over it.
Now, parking one's car near an SC: People do that all the time with reasonable success, I believe. Although there were some reports that an SC or two started disabling that feature.

lance | 15 January, 2020

It sounds like my issue is almost identical to @rdm227's, except a complete reboot usually does allow the car to reacquire the LTE signal within a few minutes for me, instead of having no streaming/satellite maps, etc. during my entire drive home, nearly an hour.
I've also posted it on DirtyTesla's YouTube collection of known bugs:

Txvo3030 | 20 January, 2020

Starting with update 10, we started losing connectivity and screen goes black. Can reset screen and connectivity but goes down again. Tech support says working on it over a week but no correction yet. They say they will notify when complete. The connections will come and go while you drive. Not a really safe situation. | 24 January, 2020

I started having issues close to my house where I park if I’m not parked inside. Weak WiFi there, decent cellular. It appears when it finds the weak WiFi, the cellular goes away. So with weak WiFi I can’t connect to the car anymore with my app. Does anyone know if both stay on, or if WiFi connection turns off cellular? (The cell signal definitely disappears)

EVRider | 25 January, 2020

@jamie: I’m not sure, but I believe once the car connects to WiFi, it won’t use LTE for internet access. However, I thought that the car would still remain connected to LTE because that’s the only way the Tesla servers can ping the car when they need to (for example, to notify them when an update is available).

The Model 3, unlike Model S/X, disconnects from WiFi when it’s idle, so if you’re trying to wake the car, it should be using LTE at that point.

g.donovan | 29 January, 2020

Is anyone else seeing permanent LTE failure to connect, rather than the intermittent and slow-to-connect problems?

wesleyr | 29 January, 2020

I’ve been experiencing this since yesterday, no connectivity even after several reboots

g.donovan | 30 January, 2020

Boo. Let me know if/when/how you get yours fixed! Still waiting for a call back from here.

brownh1976 | 1 February, 2020

5 days now without LTE tried hard and soft reboots. Phoned Tesla Manchester and they said mobile tech in three weeks will sort! I very much doubt it to be honest a need a full network diagnostic year down.

brownh1976 | 1 February, 2020

Also in conjunction with no LTE the app has show “connecting” for two days - shocking!

brownh1976 | 2 February, 2020

LTE back now after days without!! I think it was a problem at the mothership and not
My car.

KY | 3 February, 2020

Hi guys, I just solved the problem!!!

Reboot the car is also fail.

Success to connect:
- Uninstall the APP (android). Re-install the APP. Then OK right now. (I have try to connect sometimes, all success.)

Effopec | 3 February, 2020

I get this very briefly almost every time I get into my car to leave my office. Seems strange because I get 5 bars of LTE in the parking lot. When I get in my car it generally says no connectivity, along with no music and NAV calculating without traffic data. It all seems to reconnect within 30 seconds, but if I was listening to Spotify previously the connection is cut and I need to start up again. This doesn't seem to happen much when I am parked elsewhere, just my office - though that could be a time thing rather than location. I keep hoping this gets fixed every update, but so far no real improvement.

g.donovan | 4 February, 2020

New connectivity board ordered. Hopefully that does the trick.

imitating | 8 February, 2020

We park our model 3 two levels underground... so the connectivity issue is nearly a daily issue for us. Once we’ve left the garage, sometimes just opening the Tesla app works, usually it doesn’t. Half the time just waiting about an hour brings it back on its own. Most of the time a reboot works, occasionally it hasn’t. I certainly think having to reboot daily is not a desirable experience though.

wesleyr | 21 February, 2020

They ended up replacing the HW 3.0 computer to fix the issue for me

erling | 21 February, 2020

Model 3 suddenly showing no connectivity. Have tried reboot, did not help so far. I'll retry!

voersaa | 21 February, 2020

I also encountered this for the first time today. erling your user name makes me think that you're from Denmark? Perhaps it's a Danish network provider thing.

erling | 21 February, 2020

Voerså, you are right, I live in Cph area. Our computers , tablets and phones work fine. But then again, they are all connected via Oister. I wonder who is the network provider in our Teslas?

thomas.husfeldt | 21 February, 2020

Yes same here today, also in Denmark, not sure what provider tesla uses..

klindt.hillgren | 21 February, 2020

Also issues for me - in DK.

erling | 21 February, 2020

Interesting! Apparently the problem is outside our cars. Hope that Tesla read these comments and do something about it. Any of you know ways to report to Tesla?

larsdam | 21 February, 2020

Same problem for me on model S p85d with LTE, suddenly lost all connection after update extra reboots didn't fix. :-(. Also in Copenhagen area...

erling | 22 February, 2020

If any of you find or get the solution (maybe from Tesla Service) please post it.

erling | 22 February, 2020

Saturday 12.00 just installed Tesla app on my Samsung tablet, and can contact the car. Apparently we are now connected again, haven't been out in the, car though. Wonder what happened.......

erling | 22 February, 2020

Conclusion: my car is back on the internet. How? No idea. Wish to Tesla Service: could you give us info on daily basis as to problems, solutions etc.? That would be useful.
