But I doubt that would work: It seems that this adapter was deliberately set up to prevent changing the service provider.

But I'm pretty sure that MP202 doesn't need authentication when downloads fresh configuration file from Netvision's provisioning server... You’re right.

I wish it was that simple. The configuration is stored in the adapter's file system, and I couldn't change it without logging in. Ah, no. I wish it was that simple.

A trick may be to publish a configuration file precisely where your device is searching for. To do this, you need to discover the search string claimed by MP202 (by sniffing with Wireshark or looking into device's console). Best wishes Hi Eli

The main point is that it wasn't fun anymore, so I just bought new hardware for this purpose. Hi,

In other words, have you tried to publish a provisioning file (with the configuration you need) at the URL address that searches your device? Hope this helps Hello Eli
