my thomson TG784n with 8.4.3.U software also has intermittent disconnection.
i am using public IP. need to reconnect eInternet everytime Internet not working.

another issue i have is time to time my browser goto mylaunchpad.com.my unexpectedly. i tried to create fake mylaunchpad.com.my at 127.0.0.1 in order to redirect back using Referrer but Referrer info is not available. this forced marketing by Maxis is annoying and i donno what i have missed when i open so many links at once.
