Hmm....
I can't ping from either desktop on my network, I think it is my retarded Verizon router.
what is it the actiontec mi424wr
okay, I am trying to decifer this..........
So, you have a desktop that is directly connected to a laptop via cross over cable? Both have the same IP scheme and are on the same sub net? Then you have another laptop that is connected wirelessly?
Do you mean you have this all running through a router?
okay if everything is connecting through one router, then every client machine should be on the same IP scheme and the same subnet, via the router's DHCP.
Then your problems could be
-faulty nic
-some kind of non standard router config
-OS corruption of some sort, like bad TCP/IP stack or whatever
Can each machine reach the internet when its all hooked up together?
Listen do these steps.
PIng your loopback address 127.0.0.1,
ping you Nic ( your Ip address)
Ping you defualt Gateway ( your router)
let me know if you can do these setps.. if one fails let me know and, ill tell you whats wrong.
Also make sure you ip address are valid.. do you know how to subnet.. what subnetmask are you ip addresses on, make sure your assigend ip address is not the subnet or broadcast address..
tell us what the IP address of each of your host is.
and tell us what is the subnetmask u assigned.
also remeber. Windows xp firewall automatically drops ICMP request ( ping, and traceroute) so make sure you change the settings of the firewalls
by going to the advance tab then ICMP. or just turn off the firewall.
but asnwer those question and ill can see what the problem is
