How to find my signal attenuation, SNR and sync speed ?
Most DSL modems/routers have admin interface that allows for viewing the actual attenuation, SNR (signal-to-noise ratio) and sync speed (or ATU-x) values.
1. Find your router's IP - type ipconfig in command prompt and note the IP address value listed as the "Default Gateway". This is your router's IP address.
2. Connect to your router's admin interface - type your router's IP address into the address field of your web browser. You may have to use the default password to login to your router, we have an extensive list in our routers database.
3. Locate the status page - once you login look through the menus for something named "WAN", "Status", or "Connection". It should contain the values you're looking for:
* Signal Attenuation (Measured in dB) - may indicate the maximum sync speed you can get
* SNR (Signal to Noise Ratio) (Measured in dB) - higher is better
* TX Power Level (Measured in dBm) - current/available transmission power levels, max 20dBm
* Sync Speeds (or ATU-x) (Measured in kbps or bps) - bitrate from the exchange to the modem
