Linksys and/or Netgear.

I just feel Aztech has no quality whatsoever. Software interface, hardware build, manual, support - they are all just horrid. My Netgear has been working for me since 2002, thank God.

The only problem with Netgear, and possibly Linksys, is that they seem to lack the tolerance for line quality. So if your wiring is sub-par these modems will drop the DSL signal. Aztech is able to suck it up and appear to receive the packets, but it's still slow.
