Cannot make WiFi connection with Linksys X2000

Question

Hey ,
I have been setting up my Cisco X2000 wireless router recently and I have it working fine for my wired connections, however for some reason when you try to use the wireless none of our smartphones,  can connect, unless using a wireless guest account.
 I tryed different security settings with different passwords, but none worked (WEP, WPA, WPA2...)
Can someone help me out on this problem? I can't imagine what would be causing this.
Firmware Version: v2.0.05
Thanks, 
Karel

Got  my solution from the Live chat:
Jermine P: Here are the steps to set up the router for cable connection:
Step 1 - Hard reset the router to ensure that all previous settings would be erased, please follow the instructions below.
1. Make sure that the device is turned on.
2. Press and hold the reset button at the back for 1 minute. Use a paper clip to do the reset.
3. Remove the power plug and wait for another a minute.
4. Turn on the device again.
Step 2 - Access the setup page.
1. Connect the main PC to port one of the router and restart it. Connect the modem to the Internet port.
2. Launch your browser (like Internet Explorer). In the address bar, type http://192.168.1.1 and hit GO.
3. A login prompt will come on, leave the User Name blank and type admin for the Password.
Step 3 - Setting up the router to work with your ISP.
1. Under Setup tab, click on MAC address clone sub-tab.
2. Enable MAC Address Clone and click on Clone My PC's MAC.
3. Click "Save Settings" button.
Step 4 - Personalizing the wireless settings of the router.
1. Click on the Wireless tab and set it to Manual.
2. Change the Wireless Network Name (SSID) from "linksys" to your preferred name (example: My Network).
3. Set Channel Width to 20Mhz and change the Wireless Channel from Auto to 11.
4. Set SSID Broadcast to Enabled.
5. Click "Save Settings" button.
Step 5 - Securing your wireless network.
1. Click on the Wireless Security sub-tab just beside Basic Wireless Settings.
2. Change the Security Mode from None to WPA2 Personal.
3. Type any word on the Passphrase field for and take note of it.
4. That will be the Password for you to connect to the wireless network.
5. Click "Save Settings" button.
Step 6 - Power Cycle.
a. Shut down the computer.
b. Unplug the power cord of the router followed by the modem.
c. After 3 minutes, plug the power cord of the modem back in and wait for the power light to get solid before plugging the router back in.
d. Turn the computer back on as soon as the power light on the router becomes solid.
e. Check your Internet connection.
strange thing is that I set the modem up this way in the first place, but without the power resets and it didn 't work. 
Thanks to Jermine P for the efforts taken.
