Wifi Tip 1
You can improve your range and coverage with better placement. There are multiple hardware hacks and qquite a few programs you can use to strengthen and broaden your wireless signal. There is also some easy to do tunings you can perform to a standard wifi router to get even better range and strength.
bearing in mind that radio waves travel out and down you wil want to put the router or access point up high. On top of a shelf or an upper floor would be best
If the angles that the signal needs to traverse are not steep and the signal doesnt need to pass through dense and thinck substance, this is obviously better. Things like fish tanks mirrors and metal work to distort your signal.
Keeping network devices far from other electronics that would cause interference would be ideal. Things like cordless phones, and monitors for infants, some microwaves, and even those bright halogen lamps can cause signal distortion.
Altering your default broadcast channel will avoid signal collision with nearby networks.
