Hello
I am trying to create Wi-Fi with combination of TP-LINK router(Model: TL-MR3020) and D-Link USB dongle(Model: DWP-157). The dongle works fine with original TP-Link firmware. But when I flash the OpenWrt firmware (Firmware Version: OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530) ), the router is unable to mount the dongle.
I followed the steps mentioned in openwrt wiki:
How To use LTE modem in QMI mode for WAN connection
.But the problem is that /dev/cdc-wdm0 is not created due to which I can't run any uqmi command after ssh into router.
Following are the dmesg logs when using D-Link dongle:
