Thanks for your post! I am sorry to hear about your issues with packet loss and high ping, I apologise for any inconvenience caused.
I have tested things from here and I can see that everything looks great, no errors or time outs inside the Hubs logs, and all of your power levels are within the preferred ranges.
Are you still having these issues? If so, how are you connected wired or wireless?
When do you notice these issues, all times of day or just specific ones?
Would you please include a recent copy of your Hubs logs in your response. You can find these by opening your internet browser, typing 192.168.0.1 into the address bar, before logging in it will say 'Router Status' in the top right hand corner, click there and all of the information needed is inside.
