Any idea what's going on here? I plug my modem into the router, and apparently to configure it I need to put my settings into the router, but PPPoA is not in the dropdown, only PPPoE and PPTP. What do I do?
It turns out that the ADSL modem is a PPPoA bridge device, the ADSL service itself is PPPoA, and the modem bridges it to PPPoE. So plugging them together works fine. The reason it didn't work is because their tech support people said that the modem is just a dumb device that has no configuration, it simple bridges the two.
After many hours of frustration, I contacted them again and a different rep said to just plug it in, force my IP to 192.168.1.2 and point my browser to 192.168.1.1. Then I could configure it. It literally had 3 settings that I set to those my ISP instructed, and instantly the whole thing worked.
Note: I installed DD-WRT onto the router before even buying the adsl modem (The reason for getting the N-12:), I don't know if it was a necessary step but I doubt it after configuring the modem fixed it.
