I just picked up a MR814v2 wireless router ($20 after rebate!) to hook up to my SBC Yahoo DSL Efficient Networks 5100 Speedstream modem. After connecting everything together, my Mac iBook AirPort card (8011.b) could not connect to the internet. The iBook could see the network, but it could not connect even though no security encriptions were set to the Netgear router.
After calling Netgear Support in India several times, I finally got connected to a support tech over there that actually knew a lot about the router! We tried several times and different configurations (including manually entering an IP address and tried spoofing the MAC). We got very close to solving the problem. However, the connections were very unstable. The Netgear technician figured the DSL Modem and the Netgear Router were both trying to access the PPOE (?) and thus were in conflict. The solution was to reconfigure the DSL modem to be passive so there wouldn't be any conflicts.
I did not have the software to reconfigure the DSL modem, therefore SBC Yahoo was sent out to reconfigure the modem. After the modem was reconfigured to be passive, the system worked fine! I am not sure what software SBC used to reconfigure the DSL modem. I hope this helps everyone out there!
