Hello, I just bought a second-hand huawei e1752 3g+ usb modem to use with my GL-iNet router.
I have never used a USB modem before and have just gone into a spiral of research that is probably completely unnecessary (hilink vs stick… flashing firmware).
So instead I thought I would just ask if anyone here has any advice to focalise my research on relevant information related to OpenWRT/GL-iNet and my particular modem.
Are there any quirks or issues to be aware of for instance?
The model I have is carrier branded, but perhaps not locked (should not be an issue I expect as it is for my carrier anyway). I have not yet received the sim card to use with it but the device shows in the GL-iNet firmware.
Am I supposed to update the modem’s firmware somehow?.. I see there is a SD card slot but all the information I can find is almost 10 years old, related to windows (I’m on linux) or related to specific carrier-branded models… Is the SD for some sort of mass storage option or do we need to flash firmware perhaps via SD?
Is it likely to just work as-is?.. Currently plugging it in does show that a modem is detected in the GL-iNet firmware.
Are there different options for running the device in different modes (hilink vs surfstick) and if so, which will be more efficient to use with GL-iNet firmware?
For this modem, can anyone point me to any ressources that will explain it’s features and how it works with OpenWRT/GL-iNet?
Any tips on using this modem - or even one with similar features will be most useful. Basically there is too much information and I’m not sure where to focus my attention to.
Thank you for your answer @alzhao - I had already read the help page but thank you.
Do you mean that setting the modem for tethering (via hilink) is preferable to using in modem mode?
When I plug in the modem it currently shows up as 3G/4G Modem - or the part “3) USB 3G/4G Modem” in the help page you linked.
I just looked for hilink firmware for the e1752 but I don’t think it exists for my new-to-me (but very old) device. I don’t even think that flashing firmware on this device is even possible under linux.
I will just see when I receive the SIM card if it works well or not. I am not worried about speed (the device is limited to 7.2mbps anyway) - more that there are so many different kind of modems that I had some advice on what to look out for with the model I have.
At least it is recognised so far which is positive.
Are there any drawbacks for using a device in 3g/4g modem mode with GL-iNet or openWRT?
Do not attempt to update the firmware.
Ignore the SD card slot - I am not even sure that will work when plugged into the GL.
Use the modem as is (do not attempt to convert to Hilink mode if that isn’t the default).
I used the gl-inet interface only to configure so I have no idea what is happening in the background… I could not really find any entries in the usual places one might look in openwrt so I did not look further. As far as configuration is concerned, I chose “manual” then selected the right APN and user name and password provided by my network operator. I used my laptop to remove the pin lock on the simcard.
If you have some “cat” commands to run I’ll happily post the outputs for you,
