I recently upgraded to 20mb VDSL and have the Billion NXL 8800. My connection keeps dropping after a few hours. Telkom tech has been out to my place and says line is fine. SNR values 25 down and 35 up. Attenuation is 7.8 and 14.1 respectively. Any suggestions will be appreciated. Also does anyone know whether there is an updated firmware for the router as I searched and cannot find anything. Thanks for help.
