then you can try rmnet0 mode in AT!USBCOMP you might also need to install the correct USB driver " MBPL\_DRIVERS\_R44\_ENG5-bin.tar": > **[Mobile Broadband Package for Linux (SDK, Drivers, Documentation)](https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest/#sthash.ZXRwiiKx.dpbs)** ---

Did you install the correct USB driver?

Hi @jyijyi we are connecting it with OpenWrt Router, not a ubuntu PC. that support only uqmi. so when we check **uqmi -d /dev/cdc-wdm0 - -get-data-status** it did not give any status or error. 1. can you please confirm if this uqmi working at your side? 2. can you let us know how we can switch modem to only QMI mode?

Hi @jyijyi , did you have real ubuntu PC or VMWare Ubuntu? Ans:-- No its not real PC or VMWare, its a customized Openwrt router run on Ubuntu. You can try that first to make sure your module works with the PC? ANs:- Yes its work with , real Ubuntu as well windows PC. You can also try to install uqmi in your Ubuntu PC, but I don’t quite see I can install it in my Ubuntu 18. Ans:- Will try this. As said before, both MBIM and RMNET mode support QMI protocol Ans:-- is there anything do we need to disable which causing conflict? as we i told , when we trying to connect with modem with UQMI there is no response from Modem.
