Click start-run, type CMD, then enter.  At the prompt, type ipconfig /all. The SSID is in the setup for the router - access using a browser (in the ipconfig it'll be the gateway address).  That is, http:// 192.168.0.1 (or whatever your gateway address is).  
Hello.  I'm on a Studio 15/WIndows 7.  I am following the instructions for set up of MAC filtering in the Dell Technology Guide for this laptop that I downloaded from the Dell website. (Mind you, the guide is not updated for Windows 7 yet) So I click the start button and type "ipconfig" in the box.  I do get a possible program so I double click on that to open it and it flashes on the screen maybe on second  then  closes immediately and  I can't see any of the info on that page much less follow the rest of the directions in the guide.  Any ideas how I can make that stay open to read the MAC address and put in the filtering things?  Or, any other ways to get to that page? I'm also trying to figure out where I can find the SSID info so I can make sure I have the correct setting there. No luck with finding that yet.   Sorry to double dip on my question! Any thought are MUCH appreciated.
