After use this patch Wifi6 connection working? Becouse I switch modem.img from the original to this (fw_garnet_miui_GARNETGlobal_OS1.0.6.0.UNRMIXM_047bdb5ebf_14.0) and my wifi6 connection not working... Only Wifi icon on the bar I check it wifi5 the connection.
If I have LTE connection, icon is LTE and LTE+ is this have 5G and 4G connection icons?
 
At the moment I use modem.img from garnetglobal1.0.6.0unrmixm, I'm connected at home wifi, and on my device says wifi technology 5, but on other device it's says it is wifi6, I'll try the fix now and will write in several minutes...

It's same, wifi 5, just flashed the modem from this fix

Back to the previous version. Wifi 6 not working, and Sim card signal lost after sim connected to the provider after few second after connected.
 
I think it is the same img. file modem.img from version OS1.0.12.0.UNREUXM = modem.img from GARNETGlobal_OS1.0.6.0.UNRMIXM (both 342,413,312 bytes)
Or maybe not, I also reverted back to modem.img from GARNETGlobal_OS1.0.6.0.UNRMIXM, but using script from this fix.

Hi. I flashed this modem version on latest stable Miui 14 (14.0.15.0) and mobile reception disconnects pretty often. Do I have to flash another version?
 
My package is after HyperOS / android 14.
Not intended for MIUI 14 / android 13.

Can you please tell me how to extract modem from miui 14 rom? I have downloaded 2 roms, first one was recovery and the other fastboot version. I extracted both and could not find modem image
 

XM Firmware Updater

The ultimate script that provides firmware packages for Xiaomi devices.
xmfirmwareupdater.com xmfirmwareupdater.com
If you downloaded the fastboot ROM the name of the modem is "NON-HLOS.bin".
 
Tested many version of modem.img from different rom, but this 2 working good (V14.0.6.0.TNRMIXM and OS1.0.6.0.UNRMIXM). Only Wifi6 not working. All wifi connection is Wifi5.

I have similar experience, but is garnet capable for wifi6 at all?
With both moderns I experienced some network disconnection when going from LTE to 5G, when reception is low. It takes some time for reconnection.
But all in all it's ok
 
The proposed modem doesn't work for me. Everytime I receive a call, the connection to the network is lost.

For the moment, the only modem that works is the global version OS 1.0.6.0.UNRMIXM. But it's not perfect, because there's no wifi 6 as mentionned in previous posts above, and the data connection goes from 4G+ to H+ when receiving a call.
 
I just installed OS1.0.1.0.UNRCNXM Xiaomi.eu version on my Poco X6 5G (Garnet) and the module that partially worked for me is from OS1.0.6.0.UNRMIXM firmware. The issue is that it is not so estable and eventually losses connection. I appreciate all the xiaomieu work and understand why it has not been included in the main stable build but not sure why someone would use a rom that has problems with cellular connectivity, which is a core functionality.

No matter which modem I choose, I always have connection problems, when changing from edge to 5g or from 4g to 5g. Sometimes, in between, there is no connection for quite some time. And sometimes connections stays at 5G although it should change because reception is too low

I also use the modem.img tool OS1.0.12.0.UNREUXM and everything works fine and there are no bugs. I don't know, maybe I was just lucky, but I did everything strictly according to the instructions above and everything worked as I wanted it to.

Also had the same problem before, and this modem.img from gogocar62 also works fine on my Poco X6.

656Mps with Wifi5, I don't have acess to a Wifi6 router to test.

807Mps with 5G sim card in Portugal.

Regards

I think that our phone don't have a Wifi6 modem!

On Gsmarena website it's says Wi-Fi 802.11 A/B/G/N/AC and for WIFI6 it's the AX protocol.

The POCO X6 Pro with Mediatek Dimensity 8300 have Wifi6.

Thanks for that! How long does it take to finish the first step? It's waiting for device quite a few minutes so far but nothing happens. SHould I just wait? or Am I missing something?

The zip file is in the phone's storage, you reboot the device in recovery and install the zip.
