I am currently on "Plus" broadband and it says that i have a dynamic IP. Now when plusnet refresh this IP address would this cause my modem to lose sync? If so would this be cured if i upgraded to "Premier".
All dynamic means is that every time you login the plus server gives you an ip address from the pool of address. If you have a static address then this is your address when ever you logon. To you sync questio no this will not effect it.
