I hope Optus is listening and get a better and more reliable router for their customers especially those that experienced such problems. Even their technician that came out to check it, acknowledged that the issue was with the router. I got 3 new routers and cables from them. Every one I tried had the same problems, worked initially but failed after a day or two. I even offered to buy my own better quality router but they refused to support that and give me the code to set up the landline. That's why I developed the work around which was accepted by them. Still waiting for them to come up with a better router than the Sagemcom offered.
