I properly installed my WRT54G wireless router and have my internet working fine on my computer. All the proper lights are working on the router as well. I am having difficulty connecting to xbox live. I am using the xbox wireless adapter also. My xbox recognizes the network and has 4 green bars so the connection is good. It is set up to infrastructure, and the security and SSID are correct. When i try to test my connection, it says "Wireless Network Not Connected". Apparently my xbox notices the network but I cant get them connected. Someone please help, I greatly appreciate it. Merry Christmas!
I just did the exact same thing and got the same message. When I did the test the first time, under the WPA key, I typed in Personal. When I ran the test, I got the same message as you. then I typed in the Encryption Key letters and numbers instead(it's a 22 digit code) of Personal, and the test ran fine until I got down to X Box Live-it said FAILED. This is now where I am stuck.
check whether any other wireless device / computer can connect to the wireless network..if yes, i think that the issue is with teh x-box..if you do not have any wireless computer to check the connection .. verify whether the x-box can connect to the router without any wireless security enabled..
