Odd your first hop is 10%. Something is not right off the bat working from your computer through your router. Could be the cable connection to your house.
I would suggest checking your signal quality to your cable modem. You do this by finding the brand of your cable modem, getting the default IP address from the net, then plugging directly into your cable modem. Restart your cable modem and hit the IP address. Jot down the signals you get and research to see what this translates to. Anything below par should be reported as line trouble. Be warned though that if it's inside your house they WILL charge you. So if you have a laptop, I would confirm your poor signals at the box outside where it comes into the house. BIG pain in the butt but you'll be able to find out what signal you get there too. If it's better outside then you will need a new line from outside to in. If it's still bad then you have a printout you can show them. They can use their meter to test and will probably find a weak signal too. If they don't...ask them to show you the results, if they refuse, call and ask to have a supervisor sent out.
The other hops are obviously bad too. but nowhere near as bad as mine. 2 hops with 50% packet loss on both. Horrible. Makes scoring hits very tough.
