Im sure there used to be a function on the website where i could see my predicted speeds if i was to upgrade to a faster connection speed. Cant find anything about upgrading from medium to large on the site and when i use the speed checker i get this message -
Sorry, we can't run a speed test from your location
The TalkTalk speed checker helps you find the upload and download speed on your computer or laptop. Please make sure you're at home when you run this test.
