Chnaged to unlimited and need some help

[#1]

I have had unlimited for 14 days and it is running really poor, i have noticed that my game has started laggin (Guild wars 2) and streaming anything above 420p resolution lags and constantly is buffering. I am directly connected to the router with only myself connected but still i have these problems. I have noticed if i do a speedtest in a row they is a 7mb drop.
I have no idea what to do now.

What are your router stats when you look under "Broadband Connection"? http://dsldevice.lan/cgi/b/dsl/dt/?be=0&l0=2&l1=0

Your problem is the appallingly high number of errors
One thing you could try as a short term fix is to resync the router in the late evening which should drop the speeds and hence reduce the errors
If you check the stats before and after you will probably find that the downstream noise margin increases fron 1dB to 3dB
A few questions - can you try the test socket and see if that fixes the problem. If it does your problem is likely to be your internal wiring

Hi there,
I've run some diagnostics but can't see any obvious issues, I'd give Oldjim's suggestions a try anyway, let us know how you get on.
