Hey,
Forget about these tiny things called modems, If you want serious internet, sign up for Zuku Broadband.
They r at least 96% reliable - you get fast net that you can work with. I used an orange stick once and
most of the time I was experiencing suicidal thoughts waiting for a page to load.
And for crying out, they r affordable.
BTW, am in L.A and zuku wako juu.
