Project 16 - Wireless Security: Encryptions

What is WEP, WPA, WPA2, TKIP, AES?

WEP: The old wireless standard, which is easy to crack.

WPA: Its the improvement to the WEP, and it is the current wireless standard.

WPA2: Is two generations after the WEP

TKIP: It replaced the WEP encryption system; it added more security features to the WEP

AES: Today's preferred encryption system; replaced TKIP

What is the newest wireless encryption standard?

AES used in WPA2

Which is a better encryption standard to use? Why?

AES is better to use than TKIP because AES is government-grade encryption capabilities.

Project 14: Installing Wireless Routers

I placed my wireless router where it can provide the most coverage, the center corner.

I made sure the my wireless router is as far away as possible from the microwave, which is located in the right hand corner of the house.

Project 13: How to choose a wireless router

Speed Ratings: Some routers provide high speeds but won't necessarily increase the speed of your network, so get a router that provides sufficient speed.

Popular Models: Buy a router that has good ratings from buyers and critics.

Warranties: Always buy a router with a warranty just in case you're not entirely pleased with the router.

Cost: Don't assume that the latest models will provide the fastest speeds. Even the some of the older models can provide sufficient speed, so keep in mind that last years model can be just as good as this years model. Take the chance to buy something a good price.
