In addition, WPS should be disabled as itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s very easy to hack and capture the router PIN, which can then be used to connect to the router. So if you need to remember something from all this, itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s this: WPA2 is the most secure protocol and AES with CCMP is the most secure encryption. WPA2-PSK and WPA2-Personal are interchangeable terms. WPA uses either a 64-bit or 128-bit key, the most common being 64-bit for home routers. There have been some issues found in WPA2, but they are only problems in corporate environments and donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t apply to home users.

In terms of security, AES is much more secure than TKIP. In WPA, AES was optional, but in WPA2, AES is mandatory and TKIP is optional. The biggest change between WPA and WPA2 was the use of the AES encryption algorithm with CCMP instead of TKIP. WPA2 became available as early as 2004 and was officially required by 2006.

However, it ended up having vulnerabilities that allowed security researchers to crack a WPA key within a short period of time also. WPA included a new feature called WPS (WiFi Protected Setup), which was supposed to make it easier for users to connect devices to the wireless router. Unfortunately, to keep things compatible, the WiFi Alliance borrowed some aspects from WEP, which ended up making WPA with TKIP insecure also. This was different from WEP, which used CRC or Cyclic Redundancy Check. WPA used TKIP or Temporal Key Integrity Protocol as a way to ensure message integrity. WPA was actually meant to just an intermediate remedy until they could finalize WPA2, which was introduced in 2004 and is now the standard used presently.

In response to these problems, the WiFi Alliance introduced WPA or WiFi Protected Access, which was adopted in 2003. Unfortunately, very soon after the introduction of WEP, security researchers found several vulnerabilities that allowed them to crack a WEP key within a few minutes.Р В РІР‚СњР вЂ™Р’В®ven with upgrades and fixes, the WEP protocol remained vulnerable and easy to penetrate. WEP started off with 64-bit encryption and eventually went all the way up to 256-bit encryption, but the most popular implementation in routers was 128-bit encryption. It was supposed to provide confidentiality that was equivalent to that of wired networks (hence the name). WEP or Wired Equivalent Privacy was released back in 1997 along with the 802.11 standard for wireless networks. Thankfully, only a handful of protocols were accepted and therefore itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s much easier to understand. Basically, wireless security protocols came about starting in the late 90Р В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s and have been evolving since then. IР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›m not going to go into too much technical detail about each of these protocols because you could easily Google them for lots of more information. Practically, you will only be able to choose from options 2 thru 6, though most routers now donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t even have an option for WEP or WPA TKIP anymore because they are insecure. WPA2 Enterprise is way more complex to setup and is usually only done in corporate environments or in homes very technically-savvy owners. The PSK that you see with WPA2 and WPA is basically the wireless network key that you have to enter when connecting to a wireless network for the first time. ItР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s worth noting that WPA2 Enterprise doesnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t use pre-shared keys (PSK), but instead uses the EAP protocol and requires a backend RADIUS server for authentication using a username and password. I thought several devices would not support the highest encryption, but was surprised to find out they connected just fine. If youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re not sure if some of your devices will be able to connect using the most secure method, I suggest you enable it and then check to see if there are any issues. The more secure option you can choose, the better. ItР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s ranked from most secure to least secure. If you donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t care about all the technical details behind each one of these protocols and just want to know which one to select for your wireless router, then check out the list below.
