Onstar Wi-fi speed


Recommended Posts

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

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.

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
