I have problem with this module using it in a Openwrt VM running on Proxmox. The module works at first boot, but if I turn off VM and restart, the module doesn't work. I get failed to power up MHI controller error -110, and I can't see the wwan0 port in /dev. If I turn off and restart again the VM ...

Thanks for that thought! There was an issue were the 16meg images would not work and hang up the 32meg ver. Would need to cross check what the fixes were for that bofore would be ok with applying it

(yes have the 32 ver)

What changes did you make to it and how?

oh yes :) thanks for that reminder! Most interesting!

eskaryo think had Lenovo

hmm, yea for my HP ver it was just part of the driver install but try as might the lenovo one is not interested and nothing in the logs to show it is even trying or doing any check. Some items made it sound like would happen after a reboot but still nada. And yes was on windows and the same system ...

Hello All, finaly back and got my 2nd modem.. Had a quesion, the lenovo modem, is there somthing that has to be done to get its firmware to update?

First of all, thanks for your answer. I would like to ask a couple of questions:
1) I've found a cheaper DELL DW5930e Foxconn T99W175 X55. Is this working with OpenWRT or Linux?
2) Is your HP branded T99 not working with OpenWRT?
3) I would prefer to run the module in PCIe mode in order to get ...

Hi, I’m interested in building a custom router with this cheap 5G module. I’ve found that right now this module cost about 60/70€. I read some posts, but I think things have changed through the years. How is the support in Linux right now? Do I need to patch the kernel and recompile it or is it ...

Hiya, I did manage to get it into mbim mode but found it to be unstable so have to wonder if they moved it to avoid having to fix it..

While the old command used to be AT+GTUSBMODE? and this workes on 850.
The 860 thay moves it into at@nvm:

Many thanks, got it and will be investingating it

Hello, I'm trying to build a router too with this module. Can I ask you which version of the module you have chosen? In which type of router you put the module and how is connected(pci, usb...)?

It's PCIe. But the USB hack was just publicized.

Ohh prey tell, were can i find info on the ...

Oh thanks will check out the dns items!!

RE Firmware, for sure, the latest versions have finaly brough the much needed stability! Well worth trying to update to latest!

To many anoying hangups in the modem world. have had more than my fair share!

Futher install everything usng the following searches:

I would offer one item, there was a stability issue mentioned on lenovo site about if had two of the protocols at the same time, they both try talk to the modem and it hangs it up.. if recall it was if both MHI ...

@eskaryo no problem :) good to see you still arround and keeping busy

@geraigerai For a couple of reasons would aim for lenovo! I got an HP as was better price and took ages to get needed fixed firmware and still have to hack the files for linux! While Lenovo has been far ahead on the firmware and ...

Did you ever manage to make any progress with this?

I have tried a couple of times since and still not managed to get anything to pickup in the onboard m.2 slot.
One odd item I came across was unless the sim was pressent then the modem would not start or do anything so other thought was if there ...

You got a point there. lol. Found out what my issues were. The com port was wrong , Had to use Putty to correct it. and then use some at commands on the at command. At least my 1608 router has been communicating with the modem correctly. Some reason my 3526 router has a issue with putty connecting ...

Hello eskaryo

Attaching the file as requested. it is based on 6.1.7 kernel and have seen a number of changes as the versions go up..

Now that have the system back will see about moving to the latest and test /check again as they have already got upto 6.6. rc5 so has been while since was last able ...

Hello eskaryo, sorry for the delay, things have been crazy and trying to find my power supply after a massive tidy up :(
RE: could post your mhi_pci_generic.ko file
When managed to get it up will try to get this for you. Note the version I will have is based on linux os and not openwrt..
Still have ...

Not seen any update from him :(

On the good side I had another issue were they didnt support my main router hardware at alll and can see now in the latest future test builds it got added! So have to hope that the change was made in one of those latest builds.

Have been trying to find some time to ...

Hello Xristos

Interesting to hear "I have a T99W175 HP variant working perfectly on OPENWRT."
What is the version of openwrt?
What is the router hardware?
-Quick lookup: or is it working in the Mikrotik Router OS?
Was it an openwrt from microtec or came with the router?

RE: "In order for a modem ...

am in the same boat.
If recall there was some doc saying it could run pci but the other feedback was the m.2 only runs of the USB controller and have not been able to get USB supporting one to working either.

I got a 1 gig 4 g modem Fibocom L860 LTE Module and it was not seen.. with a m.2 with sim ...

Hmm, I'm thinking it's some issue with firmware maybe?
......
Edit:
I have done literally everything possible with the help of someone to get it working (got it into some special modes, changed firmware, tried doing some other hardware etc) and it appears to have a bootloop issue that cannot be ...

Hello and the fray continues 😊
If recall -22 is EINVAL (invalid argument). Also errors before are likely the better areas to check..
Of what I can see “mhi mhi0: BHI offset: 0xffffffff is out of range: 0x1000” seems to be the most ???
In trying to check around, just for info even:
https://lore ...

Ableconn was way too much to ship to my place and also way too expensive. I probably got this for less than half the cost. If your 5G module also supports dual sim, this can do it.
IMHO if you can order from taobao, this one is the best. I also got an M.2 A+E to Mini PCIe so I can use the adapter ...

What other ports does my x86 machine have? The motherboard is an Atermiter DDR4 Turbo D4 Motherboard. But I would prefer an x1 or x2 PCIe adapter.
What about the SIM card part, do you know any adapter that adds one? My carrier doesn't support eSIM...

Took a look and looks like it may have ...

Ableconn is the best! the option to jumper pci only mode only is what makes it great! I tried another and was no go so waist of money. and the problem is many don't tell you if they are usb only or what protocols are available!

Also forgot to mention with PCIe to Mini PCIe you still have to get the ...

That would likely work as it is PCI. For the modems mentioned they are usually PCI mode only..
The other item to mention is what other ports does it have as there are other m.2 ports that can be converted over..
I have verified if the adapter is good can go from:
m.2 m key (usualy for storage)
m.2 ...

Well good news my side. With the last few updates of the kernel and the async fix things have been stable so will be ordering a new areal and when it arrives will see about moving over to it as my primary.

Thanks for the mention of the HP modem being in the MHI files already in newer kernels! I ...

First click of the download button results in a box that pops up and wants a serial number. LOL, I clicked the "download" button a second time and it started the download.

oh my :) lol didnt think to do that!
So 1st pass on looking through the file.. could not see it easily.
There is a log ...

Ahh tried to grab the lenovo driver and had the same challenge as before.. it wants a lenovo serial number.. how do you get past that or do you use the one on the modem?

Uh ya, ATT 5G is pretty much a joke. Even in areas that have actual "5G" bands it usually is nothing more than 5Mhz wide (at least everywhere I've seen). Just enough to light up the 5G icon on your phone.

What about Tmo? Their coverage is absolutely terrible in my area but luckily they do have 1 ...

/edit: @PaddyX I see you did this patch once, any chance you've got a simple guide to accomplish the same on OpenWRT or perhaps a built module I can download and just place

/edit: oh hey yes I'm certain I have usable 5g bands here, I can get 5g on my Pixel 6/7 here

Good to hear! And an advantage of having a 5g phone handy! Does mean there is deff extra fun with 5g modems!!

Interesting one on my side.. Still working on next round of 5g testing but..

AHHH Git! realy need to master using it for building! Thanks will look into it! Have another reason to look into it in that my other router is not supported but the work has been dont to get it working but months and months later it has not made it into the wild!

Couple weeks ago I had mentioned I was going to upgrade my current setup of Openwrt to the newest 6.1 kernel. After realizing that Openwrt isn't quite there yet and is beyond my ability to get it going I settled on just building the latest master branch. The really good news is that 5G seems to be ...

Fe%^$^s
So other modem arrived. is a 4g 1k.. Fired it up on the same system and after some fiddling..
a) OS did its DNS bs so have to reconfigure the dns yet again..
b) for troubleshooting moved it to a usb connector (well is nice to have that option for sure!)
c) FCC lock! oh yea now now exactly ...

oh wow thanks for pointing out your link! That is an amazing price for sure! close to a 3rd of what had been looking at!

I have a WG1608 with a T77W968 in use currently. I'm using rooter instead of OpenWRT so I don't have modem manager.

Think it is not that there is a lack of USB support it is that they do all have a 'full' version that has USB but you will pay a lot more for it!

Well dont recomend upgrading to that firmware! sp138337 = T99W175.F0.1.0.0.9.GC.004 071 IS a no no!
