Thank you very muchy. I bought the rooter package in a shop (not online). One is never too old to learn. Yes, I'm watching and learning. I've talked to 4 technical staff online to get a solution for the problem. Today I've made a long distance call for one hour and finally made it work. Now it will never be disconnected every 3 minutes. The wireless connection can last as long as I like. Anyway many thanks.
