After finally getting connected in december after a 4 month wait I have had a very stable system. Today though the router has been reading error 300 and LCP down. After reading the posts i have managed to connect by disconnecting on the connection status page and then connecting again, but it dropped out again later. Any ideas, I have raised a ticket with tier 3. Normally stats are 12,500 upstream 640 downstream, attenuation 30 and noise margin around 7. It was 9 when problem first arose.
