Problem with my wireless network?

So, I recently installed the Linksys WRT54G2.It was easy, so I grabbed my iPhone and checked if the Wi-Fi was been detected. Yes, the network name Linksys appeared and it was working already. I didn't want to leave my network open for all my neighbors to have access, so I created a name and a password. After that, it seemed ok still. Again I grabbed my phone and saw the network with the name I created along with the little lock to the side. So it was definitely locked now, I clicked on it to use it and asked me for my password. I entered my password, but it wasn't working, it says "unable to join network" on my phone. I know is the right password and my phone has nothing to do with it, because the network is been detected but I just can't access it as if it was the wrong password. I tries creating new name and passwords and resetting the router but the same thing happens. It seems that it only works if I leave the network unlocked. I don't wanna do that. Cause then everyone is going t

Just Make The Pass Name And Numbers Man And When You Do Delete The Network From Your Phone Then Search Again

I would reset the router. That should do it.

Reset agin all settings of our router and make password only numeric.

Be sure the iPhone and the Linksys are both using the same encryption protocol. For example if the iPhone uses WPA2 then the Linksys should be set to use WPA2 also. Also if the "Wireless MAC Filter" (a security feature) of the Linksys is on, then try turning it off.

If none of the suggestions here or at http://support.linksys.com/en-us/support/routers/WRT54G2 work then you can also try posting your question on Linksys' forums, http://community.linksys.com.
