At Blue Frog, we use high-quality Cisco modems with the latest stable V.90 code on our end. Most of our customers report connect speeds in the 40K-50K range. If you're connecting at a lower speed, it's possible that you may have noise on your telephone line, or that you're using outdated modem drivers on your computer. From there, your modem drivers and telephone line conditions determine the rest. Unfortunately, this is NOT a guarantee that you're using new modem drivers.
Most manufacturers provide driver updates every few months.
The newer the drivers on your computer, the better your modem will communicate with ours. If you already have the latest drivers installed for your modem, you may have noise on your telephone line. A good preliminary test you can do on your own is to use a non-cordless phone and press the number 1 on your keypad. You will get only a few moments of silence before an operator message comes on, so listen carefully. You should hear absolute silence.
