I have 200mbps service, cat 6 cable directly to pc, all has been well until a fortnight ago. Now once or twice a day, usualy late evening, my download speed drops to single figures and spikes back up to around 150 constantly and upload speed drops below 1mbps. I have repeatedly rebooted hub and pc, reset hub, changed the cat 6 cable etc etc. Not surprisingly service status shows no problems in my area. Any ideas will be greatfully received.
