      The Sky router attempts to sync at a minimum of 6.9 so anything above that is good.

      The margin will change through the day (especially in the evening when it drops). If it drops below ~5.5 you'll see problems with the connection. Below 5 and you're likely to lose connection altogether.

      If you reboot when it is below 6.9 then the router will resync at 6.9 by dropping the connection speed.

      EDIT: Just noticed you're on Connect. The above refers to non Connect packages - Connect works differently as it is really BT ADSL Max (not LLU ADSL2+).

      ADSL2 will sync with a target SNR of around 7db

      So if you sync at 10mbit @ 7db at night time, during the day the SNR will increase a bit as there is less crosstalk etc, so if you reboot again it will sync at a higher rate as there is more 'SNR db' to play with
