only

kmod-usb-net-rndis

added the output of dmesg to OP

thanks

sorry for the confusion,

the cross link (old post) of the device was showing that usb0 in dmesg

with the current firmware 24.10.1 and following https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_rndis#setting_up_rndis-based_dongles

dmesg shows the following

just for good measure

no joy

shouldn't there be a device or ifname here ?

thanks, it ideally should, problem is the device(usb dongle) is not showing up in interfaces
:frowning:

13

is it one of UF896 - Qualcomm MSM8916 LTE router ~384MiB RAM/2.4GiB flash, Android: OpenWrt? ?

are you able to get it to work using some other Linux dist ?

it is Muvit 4G LTE Wireless Dongle

it is working fine with Debian latest, just plug it in usb and it just works. nothing else required

15

Please follow instructions more precisely and only post information that has been requested.

Technically you don't have RNDIS dongle now.

this is most likely your QMI interface.

So you need to figure out why the operating mode has changed or just follow https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

Plug into the Debian PC then read that machine's log to see what driver is in use.

followed the instructions on https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

did not work :frowning:

Exactly like with Debian initially, where ModemManager sees the QMI interface, tries to use it, gives up and does some magic with reprobing. It looks like QMI is broken or not fully implemented in this modem.
This reprobing switches the modem to RNDIS mode (and another idProduct - 90b4).

yup, noticed that!

is it that 24.10.1 needs a specific driver as opposed to 23.05.3 in the sense that wrt 23.05.3 will do what debian does

in short, how can i get it to work like it was in wrt 23.05.3

thanks

edit:

will usb-modeswitch help to switch the modem to RNDIS mode
