Re: laptop can't connect to the server/ why?
If the laptop can get internet when it's wire connected, that would suggest the browser and related surfing stuff is setup correctly. It's the wireless configuration of the laptop at fault, especially if other computers can connect OK wirelessly.
Have a look at the wireless card's network connection. Is everything ini there, especially the TCP/IP setup set to auto? In particular the IP should not be the same as any other computer on the network. but when it does get allocated it should be in the same range as the router i.e. if the router is 192.168.1.1 then the laptop should get something like 192.168.1.xxx.
Could a firewall, or antivirus be causing havoc on the laptop?
Can the laptop wired and wirelessly browse (internet explorer) to the router's admin pages?
