GL-AR750S firmware dilemma


With GL-AR750S and its release firmware (3.001) and WireGuard client (gl-wg version 3.0.0-1) I can’t get the WireGuard client to work with a manual configuration. After configuring the settings, I click on Connect. It says Success. And shows so bits exchanged but devices connected to the router no longer have internet access.

I did a firmware upgrade with factory defaults using testing firmware 3.002 (gl-ar750s-0817-3.0). It brings WireGuard client gl-wg to version 3.0.3-1 and now with the same settings, connection is functional.

But for some reason, the testing firmware no longer the special character _ I am using in my WPA2 key which wasn’t a problem for the release firmware.

So: 1) can GL.inet maintain the ability to use the same special characters in the upcoming firmware release and 2) does anyone know how to keep the router on the release firmware while using the updated gl-wg client (which cannot be found in 404 Page not found - GL.iNet)?

Thank you

#1 It should support special characters for input, could you show me your password?.
#2 For snapshot ipk, you can find it in here GitHub - gl-inet/glinet: All ipks for GL.iNet's official firmware.. For release ipk, you can upgrade it on ui. The repo is located in

#1 Just type 8 characters until password box goes white, then type a single _ and you’ll see the field changing color again, indicating it doesn’t like it.

#2 The URL http : // www . gl-inet . com /lede/3.0/ar71xx/nand was the one configured in LEDE: system > software > configuration. Should it be replaced by ? Can I just add as an additional source?

Am I doing something wrong here? After downloading the snapshot .ipk from github, I try to install it but it fails:

root@GL-AR750S:/tmp/tmp# opkg install gl-wg_3.0.3-1_mips_24kc.ipk
Collected errors:

  • pkg_init_from_file: Malformed package file gl-wg_3.0.3-1_mips_24kc.ipk.

Which firmware do you use? stuck or testing? If you use the latest testing firmware, you don’t need to do anything, just upgrade the ipk on ui.

How do you download?

I’m back to the release version because of the wpa2 key issue.


my bad, i didn’t realize wget retrieved an html text file instead for some reason

I’ll try again after downloading it from my browser

Okay, I see. The repo url is different between previous release and next release. So you should download the ipk from github, and install it.

So I downloaded the ipk from github with my browser and transfered it to the router using scp - that went ok.

Then went on with opkg install… Always worried about the error messages in the output:

root@GL-AR750S:/tmp/tmp# opkg install gl-wg_3.0.3-1_mips_24kc.ipk
Upgrading gl-wg on root from 3.0.0-1 to 3.0.3-1...

Tried again the WireGuard client (through the UI)… Still saying success and this time my lan traffic was forwarded to the internet… except it was not inside the tunnel (IP showed in didn’t change).

There are probably other dependencies to be installed but at this point I should probably wait until the new firmware or packages are released hoping the password issue will be fixed by then.

I’m sorry for it. I confirm that it is a bug. It can’t work with underline.

Thanks a lot for confirming. It’s weird to me that there would be a regression bug there.
