Xp computer connected to wireless internet but cant access?

the first thing I would do is verify the computer can browse through your ISP, connect the computer directly to the ethernet cord and verify your ability to browse, if you can browse with this connection, you have a setting messed up on your wireless adapter, it looks like you have the computer configured for hard coding an IP address, check with your ISP to verify your ip address is valid for connecting to the network, if so, check your router to verify DHCP enabled, for most broadband connections you will be able to connect better with the DHCP options enabled, also a common setting is to allow DNS address acquisition from ISP there are not very many times I can think of then hard coding is necessary for connectivity. the easiest thing I can think of is to call your isp and get the settings you need from them. you seem to be connecting wirelessly to your router just fine (your wireless icon shows connection, but no internet access) if the before mentioned is what you see, hard coding may be the issue, this is why I suggest calling your ISP
