Connection problem

Hi I can no longer connect to the wireless internet through my laptop,
its a Toshiba Portege running Windows XP with Intel Wireless 2200 BG.
It was working fine but now it says: 'limited or no connectivity' and
when I type ipconfig/renew it says: 'no operation can be performed on
Local Area Connection while it has its media disconnected. An error
occurred while renewing Interface Wireless Network Connection: unable
to contact your DHCP server. Request timed out.' The IP address is

I tried unchecking the 'let windows obtain IP address' box & manually
entering an address beginning with 192, that looked as though it might
work as I no longer got the 'limited or no connectivity' message & the
wireless said it was connected, but when I opened a browser the page
wouldn't load.

I've done a virus scan & none were found, & I haven't installed any
new software or hardware since before it stopped working.

Any advice would be really appreciated, thanks

  1. Before worrying about anything else, restore the settings to how they were and try connecting the computer to router by ethernet cable.

    If it works the problem is probably wireless. Most likely reception or interference.
  2. Hi thanks for your reply, I haven't got a router unfortunately so can't test that. I can only connect via wireless.

    Might it be that it's not communicating with the DHCP server so isn't being assigned a proper address? I get messages including 'The network did not assign a network address to the computer' and 'following action cannot be completed- renewing IP address'
  3. Check TCP/IP Properties.

    Start, Connect To, Connection, Properties, Scroll Down TCP/IP and highlight, click Properties and check that Obtain DNS and IP address automatically are enabled.
