Hi, After the DNS issues yesterday I was restarting the router to attempt to fix my connection but ever since that I've been getting the "connection could not be established: concentrator not reachable" error. I've rang the call centre a few times, the problem has been isolated to the previous session that was not ended: session kills have been attempted but have appeared unsuccessful. Since then I've raised a fault, but I've not had any response since yesterday afternoon. I was hoping I could get more help as to solving the problem, I really could do with having the connection back up ASAP as I've already missed out on some significant work time. Any help would be appreciated. Thanks.
