Hi all,

         I have a 4G LTE Dongle with me and i want my device to connect to internet using LTE. But whenever i try to connect my device , it connects through 3G. Can any one help me on this.

I also want to connect my pc to the openwrt device and use the internet connection using the dongle connected to the device. Where can i find the procedure for this process.

Regards
Sheriff Manzoor

Do you have LTE zone in your area?
Did your operator enabled your SIM to use LTE internet?
What LTE Dongle do you have?

You need to look at the Rooter Project

LTE uses a diferent protocol than the UMTS/GPRS/EV-DO from openwrt.
Openwrt uses ppp protocol to connect the 3g modems, but for LTE is different. It uses CDC or NDIS connections, that have no support in openwrt yet. But the drivers exists and is possible to connect using scripts that can be started automatically.
This guy was trying to modify the protocol, but no success yet.
I succeed to connect my Huawei e3276 in NDIS mode using LTE via script, but there is no web control tool for it. the e3276 uses the usb-serial port (listed as "/dev/ttyUSB1") to send commands to the modem, the protocol used was DHCP (but the IP address was provided via the serial port, weird thing), and the adapter was "wwan0".
Further details are in this topic: https://forum.openwrt.org/viewtopic.php?id=45779

check out the link, please.

The further details link opens same post, It will appreciate if can you update link or provide more information about LTE script

I've been using LTE modem for a while now.
The first approach with e398 failed, then I bought an e3276 in hilink version. The latter is important, because hilink modems don't require ANY driver to work with. They just appear in the system as another eth interface.
To be precise: I use openwrt-BB. The CC apparently supports modems much better.

I also bought the e3276 but now I am not sure if it's hilink version?  I had already compiled openwrt-BB and  e3276 works great with 3G UMTS on ttyUSB0.

But no LTE protocol. Also there was no extra eth interface on system. I am using TP-link WDR4300  v1.7 router.

I had tried other internet script but no success.

If you can see ttyUSB0, then this is not hilink modem. You could try to replace it's firmware... To be honest I don't like the hilink idea, but it solves most problems with installigk in  OpenWrt.

Thanks for reply.

I will try to replace it's firmware or directly buy hilink version.

Will let you know after trying out
