How to access Wi-Fi without the password?

Last year I received the ip address, subnet mask, router, dns and search domains all under DHCP, as well as the server and port number. After entering all the information into my iPod touch 4th gen. I could access the internet. I tried to do the same with my iPhone but it says I still need a password. I know for a fact that I did not enter a password the first time, so what exactly is different between the two occurrences? Was the first time some strange, impossible fluke?

You probably do not recall what you did. The wireless password is required unless the network was set up without one and was an insecure "open" one.

More information would be helpful. It is possible that the first time you connected you used a method known as "WPS." Via this method the device scans for the Wi-Fi information and it is provided by pushing a button on the router itself, which then sends out the info and connects the device to the network. To answer your question you can look for a button on your router usually marked "WPS." Press this button and then scan for Wi-Fi networks with your "I-device." If this does not work you can log on to your router admin page by typing the ip number of the default gateway in your web browser. Once you have access to the admin page of the router you should see options for setting up wireless networks, these vary by device. From the wireless network configuration page, tab, menu, etc… You can either see or reset the password to allow network or guest users access to the Wi-Fi network. Hope this helps, if not feel free to contact me directly.
