4G Hotspot poor performance/radio reception

[Tttait]

My 4G hotspot is barely pulling in a cell signal. Could be a problem with the cellular modem or the antenna.

I get 0.2 mbps from my hotspot while getting 100mbps from my ATT mobile phone .

I suspect there may be a bad shared antenna with the radio, as reception there had suffered there too.

Does anyone know if they use a common antenna assembly etc?

Anybody else had issues?

I’ve never been happy with my $20/month unlimited data WiFi.

I had OnStar update it once but the performance is spotty.

I keep it now because it might help in the hills for my Uber app connection.

How was it updated?

The OnStar rep did some update in real time while I was talking to her.

It's just gone from bad to dead.

The unit still broadcasts its SSID, but I can no longer logon. It appears to disconnect immediately and automatically.

I can still check vehicle status via the onstar app. I'll presume that onstar and the 4G/Wifi use the same data service. I'll ask.

Maybe the extended warranty was a good choice. More after the break.

My OnStar WiFi continues to be poor when I need it the most:

Delivering an Uber passenger to a location in the hills.

This time, I turned off my iPhone WiFi and my T-Mobile data was still working.

I received another “restart” from the OnStar rep but I cannot tell if it improved the service once I returned from the hills.

The 4G/wifi hotspot is part of the Onstar Module. The Dealer has confirmed its bad and has ordered a replacement.

I am told its a module behind the radio assembly under the dash...

Will report once its replaced.

Glad I purchased the extended warranty - cost to replace the 4g/Wifi/Onstar module was $1161.32 .

It's a pain in the butt to get the new one working, about half an hour on the phone with Onstar but we finally got it working.They had to provision it etc.
