I have AT&T DSL with a Motorola modem. I have been using an Asus 520gu router with the manufacturer's firmware. It worked, but at certain times, I would lose connection with the internet over and over. The only remedy that worked was restarting the modem. I never had the disconnect problems using just the modem. Others say that the manufacturer firmware is buggy and tomato will solve all problems. So I installed tomato 1.25 ND with USB. The installation worked fine. The router shows that it is connected and lists the gateway as 192.168.1.254, which is the modem's ip address. The modem provides the PPOE negotiation. I think this is required because AT&T looks for the modem access code. Tomato is setup, I hope properly, as the DHCP server to receive the dynamic ip from the modem. However, I have no internet access with the router connected. If anyone knows the solution, I would certainly appreciate the help. Here is what the Overview page looks like.
