Hello, My di-624 and SBC modem both have the same IP address, 192.168.0.1, and I believe this is causing some problems (the router log keeps mentioning "Smurf attack detected") and the router keeps freezing up. I tried to change the router LAN IP address, but then it won't let me connect to the internet. I'm not very knowledgeable when it comes to networking, so I'd appreciate any insight. If it makes any difference, I'm using a g5 pm with airport 4.2, but it does this even with ethernet. Thanks. Update: Nevermind, for now. I tried changing the IP address again, and this time it worked. I'll see if it improves my prognosis.
