What is the difference between WEP and WPA? Which one should I use?

Simple answer is always use WPA. WEP or Wireless Encryption Protocol is a way to encrypt your data as it traverses airways between your WIFI router/access point and end-points such as computers and printers etc., We need to encrypt data because otherwise it can be eavesdropped by anyone within wireless signal range, such as just outside your home or office. These protocols were developed to encrypt data so only the intended recipient can decrypt it. This is how the initial implementations of wireless standard IEEE 802.11 was done. The major problem with this implementation is that anyone within range can capture these encrypted packets over a period of time and can decrypt the “encryption key”. Since all the devices on a WIFI network use the same key for WEP, then can then look at all the data over the air. To overcome this limitation, IEEE came up with WPA (WIFI Protected Access). In this standard, safeguards are put in place such as TKIP (Temporal Key Integrity Protocol) based key scrambling and EAP (Extensible Authentication Protocol) ensure that it is much more difficult to hack the system. We suggest using WPA Personal, also referred to as WPA Pre-Shared Key (PSK). A number of older systems may not be able to do WEP, due to hardware limitations, and for those clients sometimes the routers downshift to WEP, which can compromise certain sessions. You can view most of these setting on WIFI router provided by your Internet Service Provider. If you need help with it, We at Q Computers can do a survey of your setup and can suggest changes to be made. We also do WIFI setup for businesses, so don’t hesitate to reach out to us with any questions.
