I have a Cisco linksys E-1000. It has four wired port and connected to internet. I was connecting one desktop pc using wired, and one laptop using wireless connection. All is managed using DHCP by the router. When I look at the connection information, they bound to the same configuration, the same gateway and the same DNS. All can access to internet.
The desktop IP is 192.168.1.125, connected using wired to router
The laptop IP is 192.168.1.126, connected using wireless to router
The router IP is 192.168.1.1
On the desktop I installing Linux Ubuntu desktop 11.10, and on laptop I installing Ubuntu 12.4, and I created a webserver in the desktop one, run at port 80.
My problem is: The laptop can ping the desktop, but the desktop cannot ping the laptop, it show destination host unreachable.
Even though the laptop can ping the desktop, it cannot open the webserver at the desktop. It show connection timeout. Please help. I don't know what caused the problem. Is there any difference a connection using cable and wireless? (router see them as different network) Or another thing caused I cannot connect to webserver, like false configuration or something?
My purpose is I want to make a network for developing django apps, and the desktop will be the server.
Sorry if my question is very basic for some people. I'm weak in networking thing, so I need help from you all. many thanks.
