Since I 'upgraded' to a Hub 3 with my V6 box my internet speeds have been slowly getting worse. I am on the Vivid 100 but yesterday and today I am recording Steam download speeds of around 200 KB/s (peaking at 306.6 KB/s).
Fine my PC is running over wireless but I have never had it so bad. Those speeds are quite frankly appalling.
Welcome to the forums, I am sorry to see that you have been having trouble with your speeds.
I have taken a look at your connection and things look ok from this side.
Are you using a wired or a wireless connection for your main devices? If wireless try wired and let us know if it makes a difference. Pop the hub into Modem Only Mode with the computer in safe mode in networking.
It may also help to see a BQM. (Please be aware link is external and we're not responsible for its contents).
