    OK ..

    im sure this is something silly and simple.. at least I hope it is.

    I have a laptop with wireless. ... I can search for wifi networks.. like the airport and starbuck... find the list of networks available.. and hit connect.. and it says conected.

    Then when I open up my Web Browser.. nothing ! Page cannot be displayed. as tho i have no connection. I have tried it with a few different places .. like the public wifi places and still nothing.. and even on a private network in my friends house

    Im sure its a setting or something.. though I have the automatically detect settings selected in the internet options.

    Its like the computer is connecting to the network.. but yet its realising that OH I should be using this connection for the Internet !!!

    Im pretty good at sorting out problems with PCs / Windows thou I have no expierence of wireless networks so am totaly lost.

    Hope this makes sense !
    Thanks
    Paddy

    When you seem to be connected, open a Command window and type
    ipconfig /all

    Does your wireless show "Yes" for "Dhcp Enabled" and for Autoconfiguration Enabled ? If not, you need to go into your TCP/IP properties and set to 'obtain IP auto' and 'obtain DNS auto.'

    If your wireless is showing an IP of 169.254.x.y it did not successfully get an IP configuration from the router or server. Is there a chance that the wrong driver is installed--maybe one for the wrong region of the world (for example, US and Canada use channels 1-11 while most of Europe uses channels 1-13).

    If not the above, post the ipconfig here. One way to do so is to type
    ipconfig /all >C:\ipconfig.txt
    This will put the results in the ipconfig text file on your hard drive; you can open it with notepad to copy and paste here.

    "( ps what is the option though for connecting pc - pc via wireless ? )"

    Glad you got it working quickly. For pc - pc the keyword is ad-hoc. Set up an AD-HOC wireless network on each PC, clearly using the same SSID. Some utilities give you more options than others; if you have the options make sure all PCs are using the same band ('b' or 'g'), same channel (auto is probably better), same encryption and key(s). Best to go non-encrypted until you get it working; then enable WEP.

    If you keep 'obtain IP auto' (as I do) it will take up to a minute for all PCs to acquire network address. You will get an IP of 169.254.x.y and mask of 255.255.0.0 on each PC.

    Check your connection by opening a Command window and doing the ipconfig /all, and then type
    ping othercomputer
    where 'othercomputer' is the name or the IP address of the other computer.
    If you get responses back, you are truly connected.
