Why won't my laptop connect to my wireless?

Ok I have a ps3, iPhone and a iPad all three are connected to the Internet. However my laptop won't it say's I have Limited access. I don't understand why my laptop won't connect but the other devices do?

Is the Wi-Fi capability turned on?
And do you need all the other devices on? You know you could just turn a few off maybe…

Limited or no connectivity usually means your ip address is ng.
Check your wirelesss adapter to make sure the radio button is checked to obtain ip address at startup. If you have a hard-coded address, your connection will probably fail.

  • Wireless Intetnet Won't Connect? The router and modem appear to be working well. The Xbox is hooked up to the router by Ethernet cable and the Internet works fine but all the laptops and IPhones which usually connect wireless won't connect. Our network pops up and connects once in awhile for a few seconds but other than that it won't show up at all. Any suggestions? Or do we just need to invest in a new router?

PS: i know its not a faulty cord, because i tried 3 different ones, and every time i plug it in or unplug it makes that background noise.
  • Why won't my iphone 4 connect by usb on my laptop? I have a toshiba satellite laptop on windows 8, I've tried to connect my iphone up to my laptop so that I can connect it to iTunes but every time I try to connect it up it connects for a second gets to the charging screen for a second and disconnects again and does that over and over again. So it basically just will not connect properly to my laptop at all. Does anyone know what this could be? Or know how to fix this problem?
