@Sunshine 

Thanks for the kind reply "Sunshine".

My main problem is that the company WindTre is missing from the ISP list I tried to add it manually but it doesn't work correctly, the connection is unstable and slow compared to the speed test done with the mobile phone, certainly the fault of the incorrect configuration.

I created ISP configuration using parameters registered on the mobile phone keeping many settings automatically (the band and the serach network), maybe you have to select them manually to get better performance.

I tried with the single Wind or Tre configurations but the speed is much reduced compared to the one tested with the mobile using the same sim in the same place.

I don't think the speed difference is the fault of the router, it makes it strange to me that the mobile phone has a faster connection than a dedicated 4g router.

If you can suggest any solution or provide me a file to update ISP I would be grateful, thanks.

Sincerely.

Ok, thanks for the tip, I will try to do some tests by setting the band manually for better performance.
I am waiting for an ISP settings update or new FW.
Thank you.

Hi @Sunshine, I wanted to ask for information;

Do you know if it exists or can you recommend a router model with similar characteristics to the "TL-MR6500v" but with the 4.5G LTE Plus modem?

I tried to do a search but I found only the model "Archer MR600" but it is not compatible " VoLTE / CSFB / VoIP " it has no rj11 telephone output.

If it does not exist, do you know if a new model like the "Archer MR600" but with an additional rj11 telephone output is being designed or built?

Thank you.

Greetings.
