Thanks for your post and welcome to the Forums. It's great having you on board with us in the Community.
I'd like to say a quick thank you to our VIP's for the helpful advice they provided while you were waiting for us to pick up the thread. 🙂
I've taken a look at the Hub itself and all is looking good from our end.
Can you please try testing the speed directly through w wired connection without the router connected.
Just turn the Hub off, disconnect the router and plug the ethernet cable directly in to the PC/Laptop instead. Pop a screenshot of the speed results here so we can check things further for you 🙂
Thanks all, finally got it sorted. To me an ethernet cable is an ethernet cable, but no you have 100MB and GB cables.
Once I bought some new ones hey presto, 210Mbps!
One issue I do have after changing Hub3 from router/modem to modem only mode is that I can't watch any catchup, recorded programmes anymore, I am getting an C130 error saying network cable unplugged. I guess this is because it is in model only mode?
