Extending your WiFi
Well, more precisely, extending your wifi signal.
Not too long ago, I bought an antenna for my wifi router, in an attempt to broaden the range of my laptop in my own house. I could barely get a signal in my bedroom. Outside, on the back porch, I could only get a signal if I sat with my back to the yard! Well, unfortunately, before I could even test the antenna, my router fried and I had to get a new one. Luckily, the new LinkSys wifi router had better signal coverage, so I didn’t need the extra help.
But, if you still do, or just want to get a little bit more out of your wireless router, this article on ZDNet titled Expert tips on extending your home WiFi range has some good suggestions.
