Okay, I already asked this question but some people are not answering them.
I have the Verizon 9100EM Router.
My Xbox is the new Xbox 360 Slim 4GB.
I had it for about 7 months and it was perfectly fine and working normal on LIVE.
Last night me and some other friends decided to play system link and did the AD-HOC option when you select a network and press Advance Search. We didn't know what we were doing so we just canceled it and deleted it on our networks.
Here is what the "more info" tab said,
"Can't optain an IP Address from your router or modem.
Your wireless network is secured with a WEP key or WPA passphrase. Your console may using the wrong one."
When I press the "Configure Network" tab, it said that the Wireless Security was using the 'WEP' which I entered when it asked me for the WEP key when selecting networks.
I tried EVERYTHING.
I tried turning the router off for 30 sec. and turn it back on. I tried to enter a manual IP Settings, Address, Subnet Mask and Gateway. I tried entering an alternate MAC address. I checked if my DHCP was turned on.
HELP ME! I JUST PURCHASED A 3 MONTH CARD!!!
The Xbox 360 in my living room has the same info on this Xbox 360 in my room. Same WEP and network. WTF.
