Query: This is not for modem.

I've been using it for two weeks, and I really disappointed about the quality of this product. It never even close to 50kbps (most likely I've got around 20k), and somethime it's really hard to get the dial-tone.I really don't want to make a hole through the wall, and I was hoping that it could work for me. But I guess it's not. I am much better off with long line. Don't use it for your modem. This is not for your modem.
