I have been with you for several years. My download speed for my fibre was usually always around the 30-35 mpbs mark. However after noticing a major reduction I performance I have tested it and I am now getting around 7 mbps, which is rendering it near unusable at times. When I tested it prior to this back in Jan/Feb it was still around 30 mpbs. Can someone look into this please?
Is this the sync speed shown on the router, or a speedtest? If the latter is it wired, wireless, or both? Are you aware of any issues with your phoneline at all?
Subject to that I have flagged this up to the online support team for you, if you haven't done so already make sure that your personal details including TalkTalk landline number are complete on your community profile so that they can link your forum identity with your account and then give them a day or two to respond.
I've run a test on the line which hasn't detected a fault and the sync speed looks ok. Could you try switching the router off for a full 30 minutes and then retest the speed again to see how it compares.
