Query: Has problems with dynamic connections

I bought this router to use with my dynamic PPPOE DSL connection. The setup and interface were easy enough to use, but no matter how I configured it, it would not connect to my DSL connection. The router would get PDAT messages and disconnect immediately. I found out that other people have had this same problem with this router.Also, I couldn't get the router to update its firmware. It would repeatedly give me a message saying that the firmware version is incompatible.
