Vehicle hotspot won't appear on laptop

I can connect three other devices to the vehicle hotspot without issue. I can also connect the same laptop to my home network without issue. Laptop will not find vehicle hotspot.

Not sure how this relates to AT&T as there's not enough information to go by... so just a few questions.

What vehicle?  What are the other devices that do connect by type, like are they phones, tablets, whatever?

Can you determine how those other devices do connect? Does it tell you if it's on the 2.4GHz or 5Ghz band (if it's a dual band hotspot)?

I assume that the hotspot is just not showing up as an available network when the laptop is scanning for networks.  Maybe you have to reset the network settings on the laptop. 

Have you tired manually connecting?  That is, typing in the network name and password directly as a new connection even if you can't see it. It's what you do when connecting to a hidden network.  The hotspot usually isn't hidden but some setups do allow it to be on but hidden so it doesn't show up by random people as you are driving down the street.  Once you have the network info in a device, whether it's hidden or not wouldn't matter, the device will connect.  Maybe your other devices were manually connected, or connected while the hotspot was visible, but has since gone hidden.

Those are just a few things I can think of to check.

This is an AT&T hotspot, hence I am posting here.

The vehicle is a 2022 Ram 3500.

I have connected two different Android cell phones as well as an Apple iPad to the hotspot without issue, one of which was connected for the first time today to rule out the already connected devices issue.

The display in the vehicle says it is a 4G hotspot. I don't know what the successful devices are using to connect. The laptop is able to locate many other WiFi options in my area, just not the vehicle. I have tried manually connecting with no luck. 

I am assuming that since my laptop is several years old it's wireless card is simply not compatible with the 4G band.

Hello @nyfireman22, we would like to help shine some light on why you are not able to connect some devices to your built in-car Wi-Fi.

 

To bring you faster speeds and new features, we're excited to upgrade America’s Best Network. One change we’re making is shutting down our 3G network in February 2022.  Effective February 2022, AT&T is discontinuing support for 3G devices, including some vehicles with Built In In-car Wi-Fi.

 

  • For your impacted, automotive manufacturers are working on solutions and will be communicating directly to our customers. AT&T has been working closely with automotive manufactures to provide support during the transition.

 

  • If you have specific questions about the 3G shutdown to your vehicle, it should directed  to your automobile manufacturer for more information.

 

Please let us know if the information provided is helpful.

@ATTHelp I'm not sure how this applies to my situation, as my vehicle indicates that it is a 4G wireless hotspot, not 3G.

We do understand how important it is to be able to connect all your devices to your built in-car Wi-Fi @nyfireman22.

 

The 3G shutdown may not apply to your car, but to the devices you are trying to connect to your vehicle. Devices in this list are tested and approved for the AT&T network. You may have an out of date device that is not able to connect to our networks. Can you please share the device make and model that you would like to connect to your vehicle? The device you are trying to connect might be the issue if it is not supported on our new 5G networks.

 

Thank you for reaching back out to the Community.

@ATTHelp So it sounds like my suspicious are likely correct, the laptop I'm trying to use is simply not compatible with the newer network. Since it is likely a decade or more old, that doesn't surprise me. It is an HP G60-549DX. I've sent for a wireless USB device to try to connect without using the laptops built in wireless in an attempt to connect that way. Thank you for your help.

A few things need to be cleared up.

The truck display may say "4G Wi-Fi Hotspot", but that is only how the the signal is getting to the truck.  It's basically a mobile data connection from whatever carrier Dodge is contracted with at this time to provide that mobile data service to the UConnect head in the truck.  In this case, it is AT&T.

From there, the data is converted by an internal router to a wi-fi signal for other wi-fi devices to connect to.  Mobile data (4G or otherwise) is no longer part of that signal.

The devices that connect to the wi-fi are NOT using a mobile connection - so whether it's 3G, 4G, LTE, whatever, does not matter at that point.  It's using the wi-fi connection like a wi-fi router in your house or business.  That's why I was asking about which band the wi-fi is sending.  For wi-fi, the connection is either on a 2.4GHz or 5GHz band ("GHz" as in "Gigahertz").  Just remember, that's not the same as 4G or 5G (where the "G" is for "Generation"), which is just the mobile network data connection type.  2.4GHz is the original wi-fi band used for many years. The 5GHz band was introduced in 2009, but didn't really become common for a few more years.

I tried to look up how the UConnect system used by Dodge provides the hotspot wi-fi, but can't seem to find much information about it.  But it would be similar to how I turn on Hotspot on my Samsung phone. 

The purpose of the hotspot is to provide a wi-fi connection to the internet for devices that don't have their own mobile data capability - like a laptop, or even a PC.  I can turn my phone into a wi-fi router and my home PC can see it as a wi-fi connection.  All I have to do is type in the password I set to access the wi-fi, and my PC has internet access. The phone is connected to AT&T via LTE, but the PC just sees the standard wi-fi and knows nothing about the mobile connection beyond the phone.

That's how devices connected to your truck wi-fi sees it.  The device only needs to be compatible with the standard 802.11 wi-fi standards and whatever security types the wi-fi is set for.  There may be some settings for the wi-fi that determine those things.  It very well could be that the security setting defaults to WPA2, and your old laptop may be too old to recognize that.

Now, I looked up the HP laptop, and the wi-fi built-in is compatible with 802.11b/g, which any current wi-fi system should support.

So, my next question goes back to your first post.  Why are the android phones connected to the truck's wi-fi?  They should have their own mobile connection for their own data, shouldn't they?  The iPad, maybe, since some have mobile capabilities (include a SIM card slot), and some don't, and some may be cellular capable but just don't have an active SIM card installed.  All that means is those devices are using up the allotted monthly data amount used by the hotspot.  As I understand it, the hotspot use is free for the first 1GB of use, or 3 months after buying the vehicle.  After that, you have to contact AT&T to continue service.  There's usually a data limit per month.

Edit - actually never mind about the smartphone question - I forgot about actually pairing smartphones for calls and such.  I was only thinking of the data use only.

So, back to the laptop, forget the 4G part because that doesn't matter.  The laptop only has capabilities of a hard-line network connection jack (ethernet cable), a 56k modem phone jack, and regular ol' wi-fi.  Somehow the wi-fi setup in the truck is not allowing the laptop to see it.  As I said earlier, my best guess is the security setting for the wi-fi itself.  There are currently 4 security protocols that can be set for wi-fi routers (and, as I said earlier, what's in your truck is basically a router):

  • WEP - Wired Equivalent Privacy
  • WPA - Wi-Fi Protected Access
  • WPA 2 - Wi-Fi Protected Access 2
  • WPA 3 - Wi-Fi Protected Access 3

I'm just guessing here, but it could be that the laptop only recognizes WEP and WPA.  If the truck wi-fi is set for WPA2, then the laptop just may not see it.

There's also the encryption method - AES, TKIP and PSK. 

There's got to be a way to check/modify the wi-fi settings in the truck's UConnect screen.

Thinking about it more, another question is - did you have to input a password to connect the other devices to the wi-fi - at least the first time they connected?  If so, then one of those protocols was in place.  It not, then I'm at a loss as to what to think of next.
