A note on changing Wi-Fi (WiFi) on Gen 3 charger

This site may earn commission on affiliate links.
Changing the Wi-Fi (#1) network on a Tesla Gen 3 charger is not as simple as it should be.

It *appears* you can do it from a web browser connected to the charger...
but when you select the new Wi-Fi SSID, you get a red "Forbidden" message,
and are left with no clue as to what to do.

The installation manual didn't help much, but did provide a clue, so
here's what worked for me ...

Let's say you're changing from network 'mywifi' to 'fred'. (I.e., the new SSID is "fred".)

Have your cellphone (#2) ready, preferably in the Wi-Fi setup page
(for Android, tap 'Settings', then (depending upon model/version,
'Network', then 'Wi-Fi').

Take the handle of the charger cable, press and hold the white button (#3)
for at least 5 seconds.
That tells the charger to open a Wi-Fi hotspot called something like:

TeslaWallConnector-######### (some number)

On your phone, you may need to hit 'rescan' (might be a semi-closed circle
with an arrow) to trigger a re-scan of available Wi-Fi access points.

When you see TeslaWallConnector-#########, connect to it.
(You might be told it isn't connected to the Internet... that's ok.)

On my Android, that connected and then opened a browser window connected
to 192.168.92.1, and should show you the charger's setup screen.
(If a browser doesn't open for you, start one up, and go to 192.168.92.1,
or scan the QR code on the side of the charger for the IP address.)

In the browser...
Tap on 'Wizard' or "Wi-Fi setup" (can't recall which, and the manual is
*conspicuously* missing any mention of the web interface!), and pick
your desired network.

Note: due to (IMHO) a software bug / design flaw, when I entered my new
network's password and clicked on the blue right-arrow (on the right of
the password field), it *seemed* to work, but the top of the
page still said it was connected to the old network, and the check mark
was still on the old network.

I couldn't be sure which network it was on (without some tedious work),
so I clicked on the old network, and changed the password to a wrong value.
While it was trying to connect, I clicked 'back' (?), and then clicked on my
new network, re-entered the password, clicked on the blue arrow ... and it worked.

Being able to change the SSID (and password) from the web interface is an
obvious needed feature, and it's probably the 30th entry on my "Tesla software
enhancement list" ... only 30, because I've only had the car 4 months :)

Good luck!

is easily searchable!

2. you can use a laptop, or other computer that has Wi-Fi ... doesn't
have to be a cellphone.

Wow, good documentation and thanks for going through that before we had to! Not exactly a user-friendly experience, was it? I've noted this post for when my Wi-Fi (WiFi ;)) network name changes.

What happened is that I had 2 WAPs, with 2 SSIDs each ... and wanted to replace everything with a mesh (Google WiFi in this case) so I could seamlessly move around the house and so each device could talk to potentially any device in the house (not easy with separate SSIDs unless I did a lot more work).

After reconfiguring 18 WiFi devices (doorbell, water sensor, Alexa, Google home, google nest, phones, laptops, and more) to use the new Google mesh, it suddenly occurred to me:

I should have turned off one of my WAPs (with the main SSID of "privnet"), and
setup the new Google mesh to have the same SSID (privnet) and password that it had!

That way, *none* of the devices setup to access 'privnet' would have to be reconfigured! (and they were the majority)

But, no...by the time I thought of that, there were only 2 devices left. (Worse yet, I have *no idea* what they are, or where they're located in the house ... but the status page on the old WAP says they're still connected :)

Had I done that, I'd not have had to change the Wi-Fi on my Tesla charger, or for the car itself.

So, in the future ... good luck!

Hello, I came across this as I was trying to switch from a Bell HomeHub 2000 (SageCOM Model Fast 5250) DSL modem to a Rogers Ignite WiFi Gateway (Gen 3) which is the XB8.

The Tesla Wall Connector (TWC) was stubbornly holding onto the old Wi-FI SSID (call it Name1) instead of switching to the new Wi-Fi SSID (call it Name 2, note the space).

I tried changing it through the app, which seemed to disconnect halfway through and then stop working. Then I tried connecting through the host page on the TWC and adjusting it through the Wi-Fi setup. That seemed to do the same thing.

A couple of things we tried:
1) Separated the 2.4 GHz and 5 GHz bands into two separate SSID's. We needed to do that for a couple of other IOT devices in the house.
2) Moved the new modem closer to the garage, as suggested.
3) Reserved an IP address for the TWC on the 2.4 GHz SSID
4) Tried to add it as a new TWC at the same address, it wouldn't let me do that, telling me that it was already registered to this address.
5) Changed the network authentication on the Rogers modem from WPA3-Personal Transition to WPA2 PSK (AES).

I still had service with the old Bell modem so I hooked it back up. The TWC showed up on that modem and was then accessible through the Tesla app so I knew it wasn't changing the SSID.

Not sure what actually fixed the issue but after trying a few more times, with the old modem still connected, it allowed me to change to the new SSID.

I suspect it was either:
1) It couldn't communicate the change to the Tesla servers.
2) Couldn't work with the new WPA3 Transition security.

I could try a few iterations but at this time I'm just happy its working. :>

Something else I could have tried:
Manually add the TWC to the Wi-Fi list using the Manually Added Wi-Fi Devices setting.

Details:
Tesla Gen3 Wall Connector FW: 23.24.4-11ab530

Hope this helps,

Maybe not the right place for it, but you could say what the wifi connection actually does? I'm going forth between getting Gen 3 or a faster Gen 2 80A since the P100D I'm looking at supports 72A.

Had my electrical redone last y ear with a 200A panel though my electrician says will need to be a direct line off the main since the garage subpanel can't even do the 60A needed for the Gen 3. Only alternative would be a NEMA plug at 50A.

Gives you a basic charging log in the app that you can export as spreadsheet.
I've found that without an internet connection mine regularly gives a "charging stopped" notification but it immediately resumes. It's annoying and Tesla know about it.
It also allows firmware updates that might do clever behind the scenes updates for the charging, don't know.
 
The log does not give vehicle info so you're better off with car app data anyway, the graphs and data is broken down and displayed well.
Hot tip, you can swipe on the graphs for it to display by month. Also press some numbers to change the stat eg % of total to KW.

The only reason I have mine connected is to stop those stupid error messages.
