Here is my network connectivity:
cable modem | |(WAN) wrt54g (default gateway, 192.168.1.1) -- earth |(LAN) | Simple Switch1 | | | | | SimpleSwitch2- neptune | | | | mars mercury | |- venus | |- laptop | saturn (Windows AD DC)
simpleSwitch2 was hanging off the wrt54g. I moved it to SW1 during troubleshooting. Nothing described below was any different. To answer some questions:
The switches have NO configuration possible. I power cycled the entire network "stack."
earth is connected via wireless to the wrt54g.
I can ping from laptop to mars, neptune & mercury. I can ping from earth to venus, saturn & laptop.
However, pinging mars, mercury or neptune from earth gives the following result.
Pinging mars.XXX.XXX [192.168.1.105] with 32 bytes of data: Reply from 192.168.1.122: Destination host unreachable. Reply from 192.168.1.122: Destination host unreachable.

.122 is the address of the machine from which I am pinging.
Pinging earth from laptop gives this result:
Pinging earth [192.168.1.122] with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 192.168.1.122: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
earth is a Vista machine. Windows firewall is off.
saturn is my DNS & DHCP server.
This is the wrt54g routing table(running linksys firmware)

Can anyone give me any ideas what the h*ll is going on? Clearly the topology is a factor
And yes, I am a space geek.
