    TL-MR3420 - Aldi SIM in ZTE MF823 Dongle

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hi, I am using an Aldi SIM (which is the Telstra network) in a Telstra ZTE MF823 4G Dongle.

    I go through quick set up and all seems fine but I cannot connect to the internet via 3/4G. I have a green light on the dongle showing that it is connected to the mobile network.

    I have tried two APN settings :- 1. The standard Telstra settings provided by the router. 2. A manual setting where the APN is mdata.net.au (this information is provided by ALDI).

    Can you please let me know where I am going wrong?

    Here is an instruction for 3G/4G troubleshooting I find on TP-Link website:
    You can check whether the dongle is identified fine or not and whether this is a 3G/4G IP address.
    These two point are important .

    Thanks, that is a very comprehensive document and I will see if I can fix the problem. When I do, I will reply to this post.
