Antenna extension for WI-FI

There are a couple of things you can do to boost your WiFi signal using stuff that you just build at home:

1. Upgrade the antenna
   Some WiFi access points and routers that have WiFi built in support replacing an antenna. You can replace the antenna with one that have a higher gain and some extra coverage.
   There are a couple of ways to do that:
2. 1. If your WiFi  access point/router supprots replacing an  antenna you can simply buy a better one (but it will cost you).
      
      
   2. You can build your  own homebrew cantenna or a monopole antenna. It all depends on your needs.
      
      
3. If you can't upgrade the antenna you can wrap a copper wire around it and hook the copper wire to another antenna, it sometimes helps.
   
   
4. Buy a reapter - repeaters will receive whatever your WiFi access point/router sends and resend it, thus, increasing the range of your WiFi.

These antena extentions are widely available from most of the manufacturers (Netgear, Dlink etc.). Try at  Amazon
