well, i have a htc hero, and a zoom adsl x6, many people have been having problems getting them to communicate, i believe i have solved the problem, well for me atleast, go onto the zoom web interface (10.0.0.2) and click system status, my firmware version was 5.0.0, now if you go to Zoom Telephonics: Zoom ADSL X6 and follow the instructions, you will get to 5.0.8, that seems to have fixed my wifi issues, and i am working fine, i will report back after 1 week to see if it really has fixed my issues
