Hi - So I have a wirless connection that won't connect.  It USED to work just fine, then another laptop came into my house and is connected, and now mine won't SEEM to work at all.  A message always pops up that says I have "Limited or no connectivity".
      There are 4 other laptops connected to the same wireless connection that work just fine.  
      When I click on "repair this connection" it says it can't renue my IP address...?
     I WOULD very much appreciate any advice.  If you have any suggestions let me know, thank you so much!
-KimmFirst suspect is the firewall you have installed (you do, right?). Is it limiting the IP ADDRESSES that can PASS thru? This can be the hardware firewall (router) or any software firewalls you may have installed.

Check the parameters of your home network.

Hope this helps. Unplug the power cord going to your router and or modem, and also turn off your computer. Leave them off for at least 15 seconds... Then, restore power ONLY to the modem and or router... Leave it alone for about 30-45 seconds, and then turn on your computer. This usually helps...
