1: Buy another internet service, which provides you a newer and stronger WiFi router with new package.

This options will NOT be adopted by most of people since it is really a money wasting solution, and, it does not guarantee you can get extended WiFi range;

Since WiFi Extenders are cheaper than before, so this option might be easier for you. You can choose it but I will not talk about this option here;
