Networking Problem

I’ve got a weird (at least to me, I’m hoping that it will be obvious to someone else) problem with my network.

I’m running an 802.11(g) router. I’ve got my server and my desktop ethernetted to it, and I’m using my laptop in wireless mode. All machines are seeing the router fine (and getting Internet access), but the laptop is not able to see the other two machines and vice versa on the network. The laptop can ping everyone, but the laptop cannot be pinged. I’m running in encrypted mode on the wireless connection, and wondering if that might be the problem. It doesn’t seem like it should be, because I would think that the signal is being decrypted by the router and available through ethernet.

Does anyone have any ideas?

[Update]

D’oh!

I’d changed my network from 192.168.1.* to 192.168.2.* and forgot to tell Zone Alarm on the laptop.

Problem solved.
