I just bought my new Cisco Linksys E1000 WirelessN Broadband router, set up the brand new cat 5 wires and hooked it to my modem. My old lap top is able to see the wireless network but my alienware lap top is having difficulty connected to it wirelessly and because of that the cd will no complete setup. Is there anything I can do?

You can find the user manual here: http://homesupport.cisco.com/?pagename=HS%2FCommon%2FDynamicWrapper&site=HSus&application=HS&locale=en_US&ppath=supportsearch&c=Page&support_keyword=Cisco+Linksys+E1000&lang=en&keywords=Cisco+Linksys+E1000

getting ip starting 169.x.x.x ... cannot access router config page. Even reset don't work

go to the linksys.com (it will reroute you to the cisco page) webpage and enter the number 21461 in the search box. It is an article number associated with setting up the "guest feature" it also shows how to disable it. hope this helps!

Have you installed Cisco connect software while setting up Your E1000 router?
If you have installed the Cisco connect then you will find all the settings there. If not then you can open the setup page of the router and check the wireless settings. Read Linksys E1000 Cisco connect

If you have Cox Cable, or Comcast, restart the cable modem.

The modem will plug into the router, it should come with a cable for this, there will be 5 ports on the router, one will be labeled as internet most likely , this is the one you use, the other 4 will be numbered and you can use any of these to connect your tower. the wireless should work automaticly for your laptop, but if you want to make it a secure network, please contact me directly and ill walk you through it.
hope this was helpful

Most likely this is not a problem with the router, but with the modem or the connection that at&t is providing to you.

I would suggest calling at&t and have them check your connection.

You should check the filters on each of your phones jacks to make sure that they are in place and properly connected. Additionally, you should check the wiring for any damage or poor connections in your phone lines.

you may want to make sure that your IPS supports DHCP or you connect using a dynamic IP address. If not supporting DHCP, you want want to login into router to reconfigure it. Here is link for more info. http://www.linksysbycisco.com/EU/en/products/E1000 I have seen similar issues many time. Good luck and let me know.
Thanks

under the wireless tab there is a setting called ssid thats the name of your wireless router just change its name

Reset your router to factory, and install software from scratch... I need more details to help you more then this?
