IPhone 3G Will Not Connect To Home Wi Fi Password Issue

Question

I discovered a solution to a password issue that I did not find a solution to here.  I am posting it for karmic equity.
I have a brand new CISCO N wireless router set for WEP.  I did not have security on my old router.
When I tried to join my secure wireless network, iPhone 3G would not accept/ recognize my new network password ("Unable to join the network ....").  Even I entered the correct "password" I could not get on the network.  I could join onto the network as "guest" using my password but only as guest, and I had to go through the Safari browser,  Wi-Fi Networks, Choose a Network.... would NOT work as guest
To connect iPhone to the password secured network (and it will automatically join in the future:
GOTO Settings
GOTO Wi-Fi Networks
GOTO Other Network
Enter name of your network
GOTO Security
Select your security (mine is WEP)
GOBACKTO  Other Network
PASSWORD:  !!!! Not my "network" password!!!!   Its actually my "wireless key" which is like 8476G29765.  CISCO refered to it as the "PASSPHRASE".  My password only gets me into the router, or connected as "Guest" but not connected to the network.
Note please that I could long onto the network as "guest" using my password, that was something like "password".  Again, to log onto the network I had to use the kryptic "8476G29765" passphrase that my router generated, but I entered it in SETTINGS / WiFi Networks/ Other Network....
Other methods may work as well, I dont know, but this worked like a charm.

Try restarting your WiFi routers by removing power for 30 seconds. Note that WiFi is not automatically fine just because some devices may be working with it.
On your iPad use Settings > General > Reset > Reset network settings
Try to connect.
