    Can't ping one computer in my local network

    Hi,
    I have two computers in my network, a dell and a eeepc. Recently I reinstalled my dell. Now, I can use it to connect to the Internet, but I can't connect the two PCs via ssh anymore. I use autoscan-network from the eeepc that can't find my dell ; and autoscan from my dell can't find eeepc... The two PCs are be able to ping the router and to the Internet, but not between them. Router seems right, and firewalls are down. It seems that it's my dell that has a problem, here are the results of the commands below:

    Code:
    iwconfig
