Huawei E5776 Mifi not connected properly

Harald · 2019-11-23T13:59:44.352Z

This appears to be problem since upgrade to 3.x firmware. Huawei E5776 MiFi when connected to USB port is not being properly recognized and connected. Device is trying to use modem mode, unsuccessfully.
It should be using tethering mode. It’s odd, because it was working just fine with 2.x firmware.
Moreover, it’s working just fine with Huawei E3372 USB modem in HiLink mode (Hilink is basically same mode as E5776, emulating USB network interface.

Tested on:
AR750S (firmware 3.025)
AR300M (firmware 3.024)
Same result on both: device is suggesting USB modem, trying to auto-configure but never finishes.
Let me stress this out: it was working before with AR300M on old firmware 2.x in tethering mode. Any chance to have it fixed?

PS.
Same problem exists with Huawei E5885L. Here I can connect using Ethernet cable, but USB is proven faster.

It’s visible it’s trying to establish modem connection while it’s a Mifi device, connecting and maintaining connection on it’s own. It should use usb network connection (tethering), just like with Huawei Hilink USB modem

It seems that you need to use the NCM protocol, which you can configure in the background.
Please refer to this link [OpenWrt Wiki] Use NCM USB Dongle for WAN connection

I dont’t think that’s the case.

it’s connecting OK to Huawei E3372 (hilink), this is same connection type, showing “tethering” properly
all modules are installed
editing MODEM_1_1 interface in Luci, changing protocol from default “static address” to “DHCP client” allows connection to be established, but still showing connection type as “3G/4G Modem” which is incorrect (should be “tethering”)

From the LOG, your E5576 does not work in HiIink mode
As far as I am concerned, there are two working modes for such devices in HUAWEI. You can ask the seller how to set E5576 to HILINK mode

E5776 doesn’t work in Hilink mode as it’s not an USB modem, it’s a Mifi.

While connectivity is similar, still bit different.
