Make sure you're entering the password correctly.

Also sometimes power cycling the router can work wonders (mines on a timer that turns it off and on at 3am). Try that and let us know.

Kind of off topic question, but how often should someone power cycle their router? My internet tends to drop off and on and really random times. Sometimes powercycling works, sometimes restarting the computer works. It drives me batty because it does it at the most inconvenient times.

We have a Lynksys router and I found mine to flake out about once or twice a week leaving even wired connections with problems. Being too cheap to just go buy another router I found that adding a timer worked for us . But rikkster's solution is great too.

Power cycling is a temporary fix. Making your phone a preferred device on your wireless router is the better and more permanent solution, albeit a little more in depth than power cycling the router.

Start by obtaining the the Wi-Fi MAC address from (I assume your S2x). Go to: Settings > tap Status and scroll down to Wi-Fi MAC address and write down the alphanumeric string of numbers that appear. (Example only: 01:15:36:C2:4D:95).

On any browser, enter the routers default IP address in the browsers' address bar to gain access to the routers' settings. You may need to enter a username and password to gain administrative access. The router's default IP address can usually be found on a label affixed to the underside of the router and in most cases begins with 192.168.x.x. as an example.

Once logged in, look for the wireless settings of your router. Look for a Wireless MAC Filtering tab or setting. By adding your devices' Wi-Fi MAC address to the routers' MAC address filtering list, you can specify which devices you want to block or allow onto your wireless network.

The end result is that you will rarely if ever receive an authentication error. I've had my router set up this way for over two years and it continues to work to this day without issue. I run quite a few wireless devices including an S2x using this method, so I know this method works.

Wi-Fi Protected Set-up or WPS.

Yes, in the most basic sense, WPS attempts to establish a secure connection between a WPS-equipped access point and a WPS-equipped device over Wi-Fi by using a PIN-based method for security.

No. WPS utilizes a PIN-based method for security and is not considered as secure as the preferred MAC address/filtering method. WPS can be easily exploited using brute force methods which could easily take advantage of the weaknesses apparent with WPS.
