Speedwise there's not much difference to be honest - from the last tests I did with the THG, over Wi-Fi I got 43.48Mb/s download and 11.51 mb/s upload. Wired I got 49.61 Mb/s download and 12mb/s upload, but I don't really opt for the wired connection as the router is downstairs and about 25 meters away from my computer upstairs, and requires routing the cable up the stairs and across the landing so it doesn't look particularly great. When I can actually get a stable Wi-Fi connection upstairs the speed is fine, it's just the connection itself that is all over the place, going from full signal, to none at all, to 3 bars, etc etc. I've tried a few different antennae from the back of my PC to see if that improves the connection, and it has slightly but not enough to stop it from dropping out completely on a daily basis.
I actually wasn't aware that the THG was AC3000 - I remember trying to suss it out a couple of years ago but couldn't find any solid information, so assumed it was just your standard piece of rubbish broadband provider kit, but apparently I'm wrong!
