Been having issues with getting 5G working on both EM9191 and EM9291 modules. I have a 5G Verizon SIM and a 5G AT&T SIM. I have tested 5G connection via a Cellphone in the same location with both carriers and do have 5G showing up with no issues. Please let me know what to try or any commands that I can run to help troubleshoot this issue. One thing I find odd is within Modem Manager, the “Supported Bands” don’t list any that are 5G bands. ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/3/31304c7a48cfd4299c29bc1b54e5d3eb22170dae.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/9/94ff0987da07aa13fe042118cb664475be73b324.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/0/07acb069382f577930457c9814e538ef2090bb7f.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/2/29db68f7f1bba3ba43f50eb5314662715ab1a2db.png) ---

What is the return of the following? ```auto ATi3 at!entercnd="A710" at!selrat? at!band? AT!sdpref? AT!GSTATUS? ``` BTW, I remember you need to generate some data traffic in order to work in ENDC mode in at!GSTATUS? ---

Thanks for the reply. I have generated traffic by sending/receiving large amounts of data as my Sierra Rep suggested, but no success yet. Running the commands you requested can be found below: ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/7/74f3d97b9f4ad791d68a218ab0993ea148692cd7.png) ---

Which carrier pri are you using? Generic? Vzw? ATT? Is it the same when connected to windows? Are you connecting 4 antennas? ---

Hello, I am using the Verizon PRI or ATT PRI based on the SIM card I have inserted. I have the modem directly soldered onto a custom designed embedded board that is Arm 64 bit. Yes, I have 4 antennas connected. My order of commands after the modem is successfully connected to the internet (Ping Success) with a 4G Connection is: ‘AT!ENTERCND=“A710”’ “AT+CFUN=5” “AT!DASUB6TECHACT=1” “AT+CFUN=1” The state status goes to a “registered” state after trying to get 5G working and I no longer have a good connection to the internet (Ping Fails). Before entering the above commands, it is in a “connected” state. Possibly there are other commands needed that I am not aware of? ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/5/565bad1c63b7607f030b072f278b2ee996fc0690.jpeg) ---

Why do you need to enter those AT command? I remember sometimes ping is not enough to go to ENDC mode, you might need to download a big file or browse internet ---

Hello, I am not sure I need to enter those AT Commands, if I don’t enter them, I only see 4G connection, never been able to get 5G. Those commands come from the EM9 Series AT Command Reference Manual. When I test for 5G, I send multiple MBs worth of data. I was just saying in my previous post that I was testing a ping to make sure I had any connection to the internet. After entering those commands, I lost my connection to the internet in general, regardless of 4G/5G connection. ---

i don’t think those AT command are needed to input ---

Regardless of whether those AT commands are needed or not. I have tried with and without them with no success yet. Looking for an example of how someone gets 5G working with an EM9291 module. ---

I remember there is no problem to connect 5G in VZW network: > [@EM9191 does not connect to 5G on Verizon](https://forum.sierrawireless.com/t/em9191-does-not-connect-to-5g-on-verizon/28087/4): > > I remember I used IPERF to generate traffic.
