Running on BT Infinity, get about 29Mbps download with 9.5/10Mbps upload via a wired connection (we get upto 60Mbps download and 20Mbps upload, so that's not too bad). Downstairs next to the router, the speeds increase by 5Mbps on both upload and download. Had to invest in a new router/modem to achieve said speeds, on BT's own routers we were lucky to get 15Mbps on a wired connection, wireless dropped out all the time.
Used to be on 6-8Mbps with 1Mbps upload, which was fine for online gaming. Couldn't go on YouTube or stream any video content whilst gaming. That was before BT offered an upgrade to Infinity for free, so that wasn't too bad.
