They have the firmware files for MF833v

Yes. On linux you could just do :


And I stumbled upon this file while poking around on the AR2140 router :



I thought it would be helpful for whoever encounters issue whilst setting up the usb modem

will take a look on this first...thanks alot sifu

waiting for your good news.

Hi guys,

I'm do provide unlock service for Maxis USB stick and you will be able to use the backup SIM on your PC after the unlock process. If anyone interested you may PM me.

Thank you.

Thank you very much. Finally figured out thanks to your tip. Maxis is sneaky.

I’ve successfully gotten it working on my computer just like you to verify it. Then changed the setting on my ASUS AC86U stock firmware via web GUI.

And everything works as it should, simulated by turning off the modem.

What motivated me to do this was that Maxis fiber was really down and the dongle not working is irritating since I’ve got ASUS AiMesh setup for my home.

EDIT: don’t need to unlock one lah. But I think if you abuse this backup dongle Maxis will banhammer it.

Yes, no need mess with the Dongle Firmware, just DHCP Option 12:


I use 4G Backup as Internet Fail Over, I simply set Route Distance/Metic:
Fiber: Metric 3
LTE: Metric 5

when Fiber down, automatic to LTE

Has anyone successfully use their 4g backup dongle with car android device?

even if successful unlock it, now Maxis can still suspend your 4G backup dongle simcard if you use it other than its device

Do maxis still given the USB backup dongle?

installed 100Mbps fibre last month.
pre-installation, they gave wireless dongle + router.
upon installation of fibre + another router, i returned the pre-installation router; but they told me no need to return the dongle, to re-use the dongle as backup, but they just replaced the pre-installation SIM meant for 4G wireless with new SIM meant for fibre backup.

few days after, the fibre installer called me to give a backup dongle that was meant as my backup dongle. but i informed him maxis centre already set me up to just continue using pre-installation dongle as backup, so he said then he don't need to come since already completed if like that.


(even maxis centre don't know why their SOP is, fibre installer will install new same-model router, and the one supplied pre-installation is then supposed to be returned.)

Thnk for the info. For me, I already install the fiber few months before. Last week change my prepaid to maxis postpaid. I ask for backup sim, and they give me the sim but not the dongle.

Just to update, maxis call today and send the dongle.

Congratulations, can share the dongle photo here?? Tq

Anyone know if the backup SIM able to receive SMS ? I trying to register the number from the backup SIM, seems like the verification SMS from Whatapps/Telegram is not receiving.

Thanks.

it's fully, totally meant for data-only.

Back then it can be used to receive sms. But not anymore🤭

thanks it still works
now, I want to reuse this dongle for non Maxis SIM, and it seems like I need to manually click on "connect" every time for it
poking around, it seems like it makes the following request, putting here for reference



the important part seems to be sending "isTest=false&notCallback=true&goformId=CONNECT_NETWORK" to "http://192.168.0.1/goform/goform_set_cmd_process"

im testing it with a openwrt router

I just bought this dongle off Carousell.

It works with C5V and also my D-Link's DWR-118. LED turns blue with other nonMaxis sim and can get internet.

I tried other routers (TL-902WR, DIR-506), LED turns blue but no internet.

Coincidentally I also cannot pull up the dongle's web-based management page. Can anyone help? I'd like to see if when plugged onto TL-902WR and DIR506 I can try to connect to the Internet manually,

so, here's the deal

the dongle, is locked to c5v but not locked to maxis sim
the other maxis provided routers also say they're a c5v to the usb dongle to make it work

it may have worked with the dlink briefly as with my experience
it works briefly
then it automatically downloads a firmware update, which locks things out

if you are using an advanced router that lets you send a custom hostname to the device, such as using an OpenWRT router, send "Maxis_Archer_C5v" as the hostname to the dongle, then it works

not sure what the ip address as it auto opens ufi.ztedevice.com for me
but the connect button is greyed out and disabled, even if you use inspect element to press it, it will connect but refuse to talk with the host router if it doesnt say it is a "Maxis_Archer_C5v"
