Hi

I've got a TPLink M7650 I use for work. 

At regular times, I receive in the Chrome browser the message

"Your Connection was interrupted"

A network change was detected

I've then downloaded Ping for Life, a toy that allows continuous ping. 

Pinging www.google.com (bc.. why not ^_^ that's the side I know it's supposed to be up all the time, so I though would have been pretty reliable) I see that the host IP address sometimes changes. 

Now, this does not happen when I connect to my home WI-FI network, therefore since the computer is the same, the VPN is the same, all is the same except the network (and modem) I'm using, I though there might be some config setting I can tweak on the modem.

Does anybody have any suggestion? Something I could check?

Thanks!
