Consider some of these ideas for improving the capability, performance and security of your wireless home network.
Location of your wireless router
Wireless signals work best when there’s no interference with metal or other dense objects. If you place your router up high, away from the other objects in the room, the signal will go farther.
Stay away from windows
Glass has a tendency to bounce wireless signals around, placing your router near a window may cause the signal to quickly degradet.
Use repeaters or extra routers to send signals throughout the home
Wireless signals can’t travel through metal and have a hard time going through dense objects or glass. Using repeaters (which take the signal and repeat it) can help bring connectivity to locations that otherwise might be lost.
Change the default channel
Your microwave oven, wireless telephone, or gaming console might be interfering with your router’s signal. Changing the frequency your router uses is a simple fix.
Use security and a good password
Without applying security to your wireless network, you’re making your computers and other connected devices open to attack from hackers (not to mention neighbors seeking “free” Internet access). Be sure to set your router’s security and don’t just use the default passwords.
Set Wi-Fi for the highest level of security your wireless router allows
Wi-Fi Protected Access 2 (WPA2) is the latest in network security technology. It controls who connects to the network and encrypts data for privacy. Whenever possible, enable WPA encryption instead of WEP. WEP keys can easily be cracked. WPA uses much stronger cryptographic techniques and is very difficult to break.If you find that some of your wireless devices only support WEP encryption, avoid the temptation to skip encryption entirely because in spite of its flaws, using WEP is still far superior to having no encryption at all.
