TBB Single Speedtest slower than TBBx6

Since the beginning of this week my down TBB has dropped 15mbs yet the down TBBx6 has remained the same.

Any Ideas?

That can happen with issues on you LAN.

Often rather curious and difficult to pin down. It showed up for me when I had an incompatibility between HH3 gigabit port and my gigabit switch. Other people have had it as a result of MTU issues.

That almost looks like a cap on the single stream, plus the x6 one suggests to me you may be on wireless connection to the router?

I think I've found it.
I am using Linux Mint in Dual Boot format, I swapped back to slow W7 and ran a speed test - and it was ok, come back to linux and the low speed remains on TBBx1

Rwin value might need tweaking maybe
