I am currently setting up a SOHO network with mixed wired and wireless clients using a consumer-grade 100Mbit/802.11g router. I've found that wireless clients are "invisible" (pings never returned, nmap finds nothing) from wired clients, but as soon as I establish a connection from the wireless client to the wired one, the wireless client becomes visible. To be a little more succinct:
[wired ~]$ ssh jill@wireless (no host available)
[wireless ~]$ ping wired (success)
[wired ~]$ ssh jill@wireless (success?!)
I've tried multiple wireless clients (Windows and Linux based) and they all exhibit this issue. Does anyone recognize this issue? What could be the possible causes of this?
