I have 3 WAG54G for my office. I need to use them only as Wireless Gateway and use the switch ports on the back to connect some PC (so no ADSL connection- disabled routing, nat, firewall). All the linksys are connected to the main 3Com stack switch, where we have 3 switch. All our internal network is 10.0.0.0 masj 255.0.0.0). All the HW device (switch, print server and so on) are on the 10.0.1.0 mask 255.0.0.0. The 3com switch (5 device are 10.0.1.x-5). I cannot set in the WAG54G the right subnet since the combo do no permit to enter 10.0.1.10 mask 255.0.0.0 If I leave the default 255.255.255.0 something really weird happen. during the day, when a PC is hutdown, the linksys capture some packet and start "replayng" this packet to all the network that is saturated with this traffic. As soon I unplug one of this wireless all work. More weird is that this happen if more than one Linksys is connected, if only 1 is connected all the day we work ok.
