TL-MR6400 v5 LTE modem not working

Mas · May 5, 2022, 12:50am

Hy there, very similar problem here with a TL-MR6400 v5 after

firstboot

and replacing the qmi with https://github.com/mrhaav/openwrt with

wget https://github.com/mrhaav/openwrt/raw/master/21.02.1/uqmi_2021-12-22-0.4_mipsel_24kc.ipk

and

opkg install uqmi_2021-12-22-0.4_mipsel_24kc.ipk

i was not able to initiate a connection. The simcard is working fine in a cell phone. i tried several different and even empty apn settings but it is not working.

# uqmi -d /dev/cdc-wdm0 --get-serving-system
{
	"registration": "registering_denied",
	"plmn_description": "",
	"plmn_mcc": 344,
	"plmn_mnc": 3,
	"mnc_length": 2,
	"roaming": true
}

i am on roaming, is it necessary to change the setting?

# uqmi -d /dev/cdc-wdm0 --set-network-roaming off
"Invalid arguments given"

thanks for your help!

Hi
Can you provide your config,

uci show network.<your interface name>

modem setup from systmelog

logread -e netifd

and print the result of a network scan

uqmi -d /dev/cdc-wdm0 --network-scan

Mas · May 6, 2022, 12:26am

hy mr haav,

and thanks for your reply!
Of course:

# uci show network.LTE

network.LTE.proto='qmi'
network.LTE.device='/dev/cdc-wdm0'
network.LTE.pdptype='ipv4'
network.LTE.apn='digicel'
network.LTE.auth='none'

logread | grep LTE

Can you run this?

uqmi -d /dev/cdc-wdm0 --get-device-operating-mode

Mas · May 6, 2022, 3:25am

# uqmi -d /dev/cdc-wdm0 --get-device-operating-mode
"offline"

don't know if this is useful:

# uqmi -d /dev/cdc-wdm0 --set-device-operating-mode online
"Invalid transition"

mrhaav · May 6, 2022, 6:20am

Will this work?

uqmi -d /dev/cdc-wdm0 --set-device-operating-mode low_power

Try to power reset our router as well.

Mas · May 6, 2022, 11:44am

Unfortunatly not. After reboot i got "invalid transition"

# uqmi -d /dev/cdc-wdm0 --set-device-operating-mode low_power
"Invalid transition"

After i power reset it seems to accept the command but no output on screen.

mrhaav · May 6, 2022, 12:09pm

What is the result of after the power reset:

uqmi -d /dev/cdc-wdm0 --get-device-operating-mode

Hi
uqmi -d /dev/cdc-wdm0 --get-device-operating-mode should be in "online". Sorry if I was unclear.
After uqmi -d /dev/cdc-wdm0 --set-device-operating-mode online run
uqmi -d /dev/cdc-wdm0 --network-scan

Mas · May 7, 2022, 8:18pm

Thanks for your patience!

mrhaav · May 7, 2022, 8:37pm

Do you have a SIMcard in your router and is it correct inserted? Sorry, for asking.

Mas · May 7, 2022, 9:35pm

no problem. i double checked that and i am able to get the sim state.

# uqmi -d /dev/cdc-wdm0 --uim-get-sim-state
{
	"pin1_status": "disabled",
	"pin1_verify_tries": 1,
	"pin1_unlock_tries": 10,
	"pin2_status": "not_verified",
	"pin2_verify_tries": 3,
	"pin2_unlock_tries": 10
}

mrhaav · May 7, 2022, 9:55pm

In what country are you now? Do you know which operators that are available?
Does the MR6400 v5 support the available freqensies?

Mas · May 8, 2022, 12:23am

That's indeed perhaps special. It is a french digicel simcard operating right now in antigua.

Thats what i found in the tech specs vor MR6400 v5:

4G: FDD-LTE Cat4 (800/900/1800/2100/2600 MHz),
TDD-LTE (2300/2500/2600 MHz)
3G: DC-HSPA+/HSPA+/HSPA/UMTS (900/2100 MHz)

Thats what i found for the frequencies of digicel antigua according to :

GSM bands	

    900 (E-GSM)

UMTS bands	

    B1 (2100)

UMTS protocols	

    HSPA+
    UTMS

LTE bands	

    B17 (700 bc)

LTE protocols	

    LTE

Other Operators according to my cellphone are:

Digicel-StaySafe
APUA inet
FLOW

mrhaav · May 8, 2022, 8:38am

Hi
It looks like non of the supported LTE bands in MR6400 v5 are available in Antigua.
You can try to use UMTS.

uqmi -d /dev/cdc-wdm0 --set-network-modes umts

wait a few seconds

uqmi -d /dev/cdc-wdm0 --get-signal-info
uqmi -d /dev/cdc-wdm0 --get-serving-system

mekemekex · May 9, 2022, 10:14am

Hi guys,

Sorry for the delay, I have been playing this weekend with the router and I have successfully working.

I'm not sure if it's a coincidence but what I did was:

    1. Reset the router with factory defaults (I flashed again)
    2. opkg update
    3. opkg install usb-modeswitch kmod-mii kmod-usb-net kmod-usb-wdm kmod-usb-net-qmi-wwan luci-proto-qmi
    4. This is the step that I did different, I've installed 2022-03-15-0.4 instead of the latest one:
        wget https://github.com/mrhaav/openwrt/raw/master/21.02.2/uqmi_2022-03-15-0.4_mipsel_24kc.ipk
        opkg install uqmi_2022-03-15-0.4_mipsel_24kc.ipk        
        rm uqmi_2022-03-15-0.4_mipsel_24kc.ipk 
        reboot
    5. Setup the interface through luci

And the wwan works now correctly.

network.wwan=interface
network.wwan.proto='qmi'
network.wwan.device='/dev/cdc-wdm0'
network.wwan.apn='orangeworld'
network.wwan.auth='both'
network.wwan.username='orange'
network.wwan.password='orange'
network.wwan.pdptype='ipv4v6'
network.wwan.peerdns='0'
network.wwan.dns='8.8.8.8' '1.1.1.1'

And ping now resolves correctly!

Thanks all for your help!

mrhaav · May 9, 2022, 10:44am

Hi
Great to hear

Could you just print

uqmi -d /dev/cdc-wdm0 --get-serving-system

I´m trying to find out why the operator name is incorrect in: Sat Apr 30 01:22:09 2022 daemon.notice netifd: wwan (14177): Registered to ?t;? on LTE

What name is shown in your ordinary cell phone for the same operator? Orange?

Mas · May 10, 2022, 12:48am

Thanks again. That exactly was the problem! I tried to get a signal on umts but it didn*t worked.
