I'm running WRT54Gv3 with Thibor's 15c in WDS+Access point mode (BTW it is Great firmware!:thumbup: ) This is my Device List Refresh IF MAC Address IP Address Name RSSI Lease Expires aa:aa:aa:aa:aa:47 xxx.xxx.x.133 Office 0 days, 23:57:29 wds0.49153 bb:bb:bb:bb:bb:62 -82 dBm br0 cc:cc:cc:cc:cc:20 xxx.xxx.x.100 aa:aa:aa:aa:aa:47 xxx.xxx.x.101 dd:dd:dd:dd:dd:B5 xxx.xxx.x.102 aa:aa:aa:aa:aa:47 xxx.xxx.x.134 0 days, 23:57:29 vlan1 ee:ee:ee:ee:ee::00 xx.xx.xxx.1 I know: ...bb:62 is my other WDS WRT54Gv2 ...cc:20 and ...dd:B5 are other LAN computers ...ee:00 is a mystery. It was explained at http://www.linksysinfo.org/portal/forums/showthread.php?t=47023&highlight=vlan1 but I still don't understand. It is a completely different IP scheme. I'm guessing it is either my Hub or my satellite mode connection. The Problem/Question: I searched and could not find why I have duplicate MAC addresses. The computer ...aa:47 is assigned a Static IP xxx.xxx.x.101 in the nic, however it shows up two more times with different IP addresses assigned by the DCPH server. It only has one nic, one connection to the router via a 20 port hub. As you can see it list the same computer ...aa:47 as an IP address of 101, 133, 134. The correct name only shows up on one of the ip addresses. I deleted the lease connections and they camp back in a few minutes. Why would one computer need three connections? Is it something to worry about? I there a fix for this?
