Gl-inet mudi modem e750v2

Installing and Using OpenWrt
1

modem directing me to go to 192.168.1.1 after resetting.

i can upload openwrt firmware there, but on OW's installation page for OEM, it gives me a .tar file and i need the .img file.

it is not in .tar extraction.

extraction yields:
CONTROL
kernel
root

none of OW's downloads work.

previously i used the .img file & it worked, but now i can't locate it...

NEED:
"openwrt-e750-4.0-release30319-0906-1725586285.img

It doesn't appear that the v2 is supported by the official OpenWrt project. The v1 most certainly is, but it's very likely that the v2 won't work with the files from the v1.

That said, the E750 (v1) files can be found here:
https://firmware-selector.openwrt.org/?version=23.05.5&target=ath79%2Fnand&id=glinet_gl-e750

And you can find the general info here (it clearly specifies v1, and doesn't have any mention of a v2.:
https://openwrt.org/toh/gl.inet/gl-e750?s[]=gl&s[]=inet&s[]=e750

thanks peter, but i have been uploading the files successfully, like yesterday.

the .img 4.0 worked fine; none of the other files do, and i've tried 3-5.

but i can not find the image today...

i took a screenshot of the file, i know it exists...

thanks!

4

can i upload an image here...?

5

Where are these files coming from? Sounds like the gl-inet site?

6

well, thats sort of the q...

where did i get it from...?

i think you are correct...

even though it is an openwrt file, i think i found it on the gl-inet site.

but now i can only find the 'upgrade' image "common upgrade", but that makes no sense, and its def not correct file...

7

Right. You’ll need to ask them for help since the files most certainly didn’t come from here.

Also, to be clear, gl-inet’s firmware is a highly customized fork of OpenWrt. It is not the same thing as official OpenWrt, so all support for their firmware needs to be handled by them.

8

thanks to you, i found it!

are you saying their customized OW is not as good as OW's...?

i tried using the sysupgrade from OW, but it didnt fully accept it. got to about 80%, then 'poof!'.

are you saying none of the images for E750(v2) on OW's site is for mudi modem v2, even though the gl-inet e750 v1 does show up there...?

thanks!

I’m saying it is materially different. They took a version of OpenWrt and then heavily modified it for their product. It is no longer consistent with or even from the OpenWrt project.

Probably for the best… it might brick your device.

Correct. Unless they are identical, you cannot just use the firmware for one version of a device on another version.

10

thanks peter.

but openwrt does have gl inet e750 v1 factory image & sysupgrade.

using that factory image on an e750 v1 device, assuming it installs, would be 100% OW without modification, yes?

so.....
v1 = openwrt
v2 = heavily modified openwrt

????

thanks again

11

...if openwrt made firmware for v1,, isnt it just a matter of time before they come out eith firmware for v2?

12

hi peter!

Could you briefly comment on this...?

Specifically, if it is ok to flash with OW's 'firmware selector' image for sysupgrade.

i remember what you already stated, but that might have been for the other upgrade OW page. thanks

I ASKED CHATGPT... (but maybe incorrect below)
https://firmware-selector.openwrt.org/?version=23.05.5&target=ath79%2Fnand&id=glinet_gl-e750 is this only for e750 version 1, or includes version 2?

The OpenWrt Firmware Selector page you provided is for the GL.iNet E750 router, specifically targeting the ath79/nand architecture, which is compatible with the GL-E750 series.

*********** Does this include both versions of the E750?

Yes, the firmware from the Firmware Selector typically supports both version 1 and version 2 of the GL.iNet E750, since both versions use the same architecture (ath79/nand). However, it's always important to check the device version and make sure that you're flashing the right firmware for your specific hardware version.

How to ensure compatibility:1. Verify the Hardware Version:

  • You can usually check the version of your GL-E750 either on the device itself (usually a sticker on the back) or in the device's web interface. The E750 V2 (the newer version) may have some minor hardware changes, but the firmware selector usually accommodates both versions under the same architecture.

  1. OpenWrt Support:

    • OpenWrt often uses target architectures (like ath79/nand for the E750) that are compatible with multiple hardware revisions of a router model. But to be extra sure, you can check the OpenWrt Device Page or the firmware release notes for specific mentions of version 2.

If you're flashing to version 2 of the E750, I recommend double-checking the compatibility of the firmware on the OpenWrt Wiki page or consulting GL.iNet’s documentation to be absolutely certain.

END GPT

thanks peter!

They == you, you own one, we don't.

Then I guess you're good to go, flash it, then come back and tell us how long it took you to unbrick it.

15

Yes, for the v1 hardware.

Yes, if it comes from openwrt.org, it is the official OpenWrt.

No. Don't conflate the hardware versions with the firmware. And, more importantly, understand that both of the devices ship from GL-Inet running the GL-Inet fork of OpenWrt (i.e. highly customized, with a bunch of proprietary stuff in it). Installing official OpenWrt (from openwrt.org) is optional.

To understand hardware versions, I'll point you to the Archer C7 which has many versions. All of them are generally rather similar to each other because they are using the same processor/chipset family, but you'll see differences primarily in RAM and flash storage when you look at the table.

To contrast that, see the WR902AC v1 vs the v3 which both have thesame amount of RAM and flash, but use entirely different chipsets. The firmware would not be compatible in any way from one to the other.

Now, we don't know what's different in the e750v1 vs v2 that you have, so we cannot guess if it would be compatible, or even supportable at all (it could use a chipset that is not supported by OpenWrt).

Don't use LLMs for this purpose. It's not authoritative and will likely lead you to brick your unit.

This is an important point, though... this part will be your homework:

thanks peter!

confused...

xyzant:

v1 = openwrt
v2 = heavily modified openwrt

PETER: No. Don't conflate the hardware versions with the firmware.

Installing official OpenWrt (from openwrt.org) is optional.

XYZANT: if 'no', then how can glinet state on its packaging, openwrt? sounds like they are taking openwrt's V1 & modifying it to create V2...?

CHIPSET: I will double check, but appears that for my mudi modem = V1 & V2 use same chipset.

So if chipset is same, but RAM & flash storage are different, firmware is compatible between 1 & 2, though wont necessarily install...

Yes, AI's make a lot of errors, especially in regards to computing...!

So glinet is not open-source (if it has proprietary stuff...)...?

thanks peter

First, they are not taking OpenWrt's implementation of e750v1 firmware... they took OpenWrt from some point in time, made a fork, and then used that fork as the platform upon which they developed their own GUI and applications and customizations. Their products (all of them) are supported by their own vendor firmware at launch (and they may or may not build new versions of their own firmware).

There is an opinion that it is misleading when gl-inet advertises that their devices are "openwrt," as it is a partial truth. You could say that "Shakespeare In Love" (the film from 1998) is Shakespeare in the same way that GL-inet's firmware is OpenWrt... yeah, there's a lot that is similar, but also a ton that has changed. They are most certainly not the same.

So, starting with their own firmware, maybe, maybe not. It all depends on the differences. Same chipset, different amount of flash or RAM -- sure, easy enough. Maybe a few minor changes to the circuitry, again, no problem. But chipset changes or other fundamental differences might mean that they start v2 as an entirely different firmware base.

If you're wondering how the official OpenWrt project comes to support various devices.... well, first it is a volunteer effort, and it is done after a product like the e750 is already on the market (in order to be on the market in the first place, the vendor would have made firmware as I described earlier, but that is not done as a partnership with or even contributed back to official project).

Some devices will gain support by the official OpenWrt project if they are supportable (i.e. chipsets are supported via upstream opensource linux and have been used in OpenWrt, etc.). Some devices will not be supported such as those that use chipsets that do not have the necessary open source support or when they are too resource constrained to run OpenWrt, etc..

The link I provided that talks about adding new devices will guide you through the discovery process.

The generic answer is "it depends" because there still could be other changes to the circuitry that are relevant. But the discovery process will uncover that and then the extent of the work required can become more clear.

Right.... don't use it. Or if you do, please don't ever post the LLM answers here (it may further promote AI hallucinations and cause user confusion). And, of course, if you do use AI for this, do so at your own risk.

A lot of the customizations they do are indeed not open source. Some of it may be closed-source as a function of the "software supply chain" -- for example, Broadcom doesn't opensource their drivers, so a vendor using Broadcom chips will have closed source 'blobs' that cannot be shared with the open source community. That's why Broadcom based routers are not well supported in OpenWrt.
