My new Linksys WRT54GSv2.1 (latest Linksys firmware) doesn't work on the WAN with my iMac G4 (flatpanel, running OS X 10.4.5). Has anyone else had problems with an iMac G4? I've tried replacing the WRT54GS to verify that this isn't a hardware issue at that end. The G4 works fine on the LAN, but any attempt to access the WAN fails. Other machines on the LAN (including an iMac G5 running 10.4.5) can get to the WAN fine. The problem is the same whether I use the wired or wireless interface on the iMac, which suggests this isn't a hardware issue on the iMac. The problem goes away if I switch back to my old Netgear router. I configured the Linksys using a PC in the most standard manner, and the iMac is using DHCP with no manual setttings or firewall, etc. As an example of the problem, "ping" on the LAN works fine, but ping of an IP address on the WAN or a host lookup on the WAN both get error messages involving the phrase "memory allocation error". Has anyone else seen anything like this? Any ideas what to try to make this work? Thanks for any help!!!
