My Wi-Fi is not working! Details?

My Wi-Fi was working fine. I run with century link with a modem with a router packed with it. (So its only one box). I was on my android tablet and i was messing around with my Wi-Fi settings, and what i did was i changed my Wi-Fi to static, then put in some random numbers for the DNS1.

After that, my Wi-Fi does not work on ANY of my mobile devices. (android tablet, iPad mini, iPhone) It works fine on my computer, and i haven't checked my ps3.

I have unplugged my Wi-Fi and plugged it back in, still no results

Do any of you have any suggestions of what this might be? Thank you.

Added (1). Now on my ipad, the ip address keeps changing, and all of them are different than the one that is on my computer which i think is the right one.

Also, instead of my subnet maask being 255.255.255.0 its 255.255.0.0

Added (2). It also may be that my pc and ps3 still work because they have a wired connection.

How do i enter the proper information? WHat i did to fix it was go to static, enter all the correct information, then back to DHCP. I still can't connect. And my iPad is displaying the wrong information still.

Added (3). How do i go to automatic? The only automatic i see is HTTP Proxy, then it tells me to enter a URL. How do i switch it to automatic? And my Wi-Fi is now working on my phone, and i did not even bother to touch it.

Added (4). I know nothing about this stuff, I don't want to change anything, I just want my Wi-Fi to be the same.

You have disabled the DNS for your Wi-Fi connection by entering a bogus static IP. That is why all devices using the settings provided by your router fail to look up addresses.

The reason your PS3 / PC still work may be be that they either have static IP for a working DNS or did not yet refresh settings from your router ( at which point they may also fail ).

I recommend you restore proper DNS settings. ( Usually set it to Automatic )

You have incorrect Subnet and DNS settings -- You need both to be real and accurate addresses for your internet to work.

Your subnet mask is almost ALWAYS going to be 255.255.255.0 --

Your DNS servers should be set to Automatic and not manual. This will use your ISP's dns servers.

If you want to keep the static IP, and put in alternative DNS servers that work -- Put in these numbers for your two DNS servers in windows:

DNS 1 - 4.2.2.2
DNS 2 - 4.2.2.4

Make sure your Subnet mask is 255.255.255.0

Again, or just go to automatic.

This guide should help you with the process (AND you can use the OPENdns servers the guide lists if you want to, they will work).
