When setting up WPA you will see the option for either a radius server (Enterprise, and you see this in the corporate environment) or a place to enter a passphrase (Pre Shared Key, PSK).
As long as you use the same options for both, you should be fine. WPA-TKIP or WPA-PSK is typically the names for personal WPA. My problem was not actually answered by the TP-LINK technical support staff.
So what I did was just: 1) open network connections 2) click properties 3) in the GENERAL tab, click INTERNET PROTOCOL (TCP/IP) 4) click Properties 5) choose obtain DNS server automatically My internet worked afterwards. This wasn't my solution unfortunately as I was already using the option for obtaining DNS server automatically.I moved the selection tab to WPA2 only and keep the rest the same and no luck. Ok so I setup the router to only transmit wireless N and to use WPA2 only.I moved the selection tab to WPA2 only and keep the rest the same and no luck.

I had an unsecure network connection so I changed the security settings of my tp-link router from WEP to WAP-TKIP. after that, i changed my network settings to the same WAP-TPIK option. It just says "validating identity" and does not ask for a passkey at all. thanks You want to make sure you are using the same version of WPA on each side.
