Just out of curiosity what is everyone getting on their data speed for the "4G" Wi-Fi Onstar boasts about. After 3 consecutive tests back to back I got 2.45 mbps download speed (highest). That explains why I've always had slow wifi speed. I'm starting to question if the added monthly cost is worth it. If you Google wifi speed test you'll see the first option with a button to test. Make sure you're using your trucks wifi for this. Feel free to post your results. I'm sure it'll help those who are considering either buying the service or cancel their current service. e15bc85d772124fab324f9d85627c5db.jpg

Try speedtest.net to see who the provider is and compare to those speeds.

Same issue here. I’ve about decided to shut it off.

The speed just depends how busy the network is. The onstar data package is considered prepaid service so your not going to get the same service as post paid att customers. Onstar data gets de prioritized based on network traffic.

If you setup the hotspot through AT&T directly instead of OnStar you will get full speed. Run my laptop around 20-40mbps.

Great info. Never knew that could be done.

I had my wifi through att for a while.  My checked my speeds when I was in a good cell signal range.  My speeds over wifi were similar to what was posted by the OP.  My speeds on my cell without the wifi were around 112mbs down and around 10mbs up.  I contacted Onstar about rebooting my wifi.  They sent some signal to my vehicle that "supposedly" rebooted the wifi router.  No real improvement.  I cancelled my att service for the truck.  I did get the free Onstar data plan they were just offering.  Checked my speeds again and still the same slow throughput.  

 

Does anyone know which fuse the router is on?  I think a full reboot of the system may help.

In theory, your vehicle should get better reception than your cell phone would.

I have a 2019 Chevy Silverado 1500 6.2L Ltz and had unlimited data plan through wireless carrier AT&T and got around the same speeds as the original poster, 2.5-3 Mbps. Did the reset and everything through OnStar and no improvement. Phone hotspot is obvious way to go at that point. $20 a month for unlimited seemed very fair if data speeds were similar to cellular speeds considering we are getting 80-120 Mbps through cellular

How would I set up with AT&T? (I assume that means OnStar uses the AT&T network, I didn't know that.)

I let our service lapse after the initial trial because it didn't seem to be worth the $25 or per month, when everyone in the fam has cell data. (My T-Mobile cellphone hotspot is very slow, however (<1M) so not good enough to run a laptop. Very frustrating. Technology, my A$$!)

This may be a little off topic so I'm not trying to hijack the thread but I am curious about the wifi speed. 

 

I had the 3 month trial with the onstar wifi but I never had it cancelled after 3 months because I never used it. Now I am travelling a good bit for work and sometimes need to pull over at an exit off the interstate to respond to an email or do something from my laptop. Sometimes the hotspot on my phone is very weak and makes it nearly impossible to send an email. Is the wifi strong enough to do some work on a laptop or use the wifi for carplay to use google maps or Waze? I use Waze almost everytime I'm on the interstate and its using a ton of my data. Would it be worth it to me to get the onstar wifi back?

The Onstar wifi in your truck uses a cellular modem to connect to a ATT LTE.  Your truck also has a router to send the internet signal over wifi to whatever you connect to it.  After the 3 months trial, your ATT data plan was discontinued.  If you connect your laptop to your truck wifi now, you will get nothing.  

 

In THEORY, your truck will get a better cellular signal than your phone will.  If you get a data plan with ATT, then you MAY have a signal in the truck when your phone has a weak signal.  There are different data plans, I think, so you could use up all of your data plan using Waze.  Waze is data intensive because it is sending your location to the cloud in real time.  Do you need to use Waze?  Are you using it for navigation, or are you always letting others know where you are when you are driving?

If your cell phone is AT&T, just call OnStar (blue button) and the will set it up for you. Saves you $5 a month. You will need your AT&T PIN.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
