Since yesterday evening I've noticed a rather severe drop in speed, from around 150-180Mbps to between 30-50. Upload seems to be affected similarly.
Channel acquisition seems normal, though there seems to be a number of pre and post rs errors.
I've restarted the equipment, reseated all cables, run the online check and even reset the router to factory (the backup config option appears to have gone, so thanks for making that much harder).
Nothing appears to be noted as a current issue, is anyone else affected? Is there anything else I can try?
