Thank you very much for your help. I have studied the option of remote access but I have not achieved it and I think the problem is because I have a dynamic IP from my Interner provider.

Hi. Do you know if it is possible to upgrade to any of these newer versions? Or will I have to buy a new one?

I have problem my router does not appear in the Tether app the only way to see it is when I am at home and connected to the Wi-Fi network. Can someone tell me how I can control my router from the app...
