Had Infinity 2 installed a week ago. Download speed on my (wired) PC a healthy 70-75Mbps. Upload remains stuck at under 1Mbps. BT tell me it's my problem. Hardware issue ?
Just to confuse things further, my partner's wireless laptop, 20 feet from the router, shows speeds of 12Mbps download and 14Mbps upload ! Where on earth do I go from here?
