Thats a much better connection! The speed and test result won't go up immediately as the system needs a length of stability before it increases the profile.

There's one more step to this. You need to leave it there for sometime and regulary check what the livebox shows for the downstream rate.

If it stays the same then thats the ideal result, it means it's your phone wiring causing the problem. A little bit of variation is ok but the longer it stays the same the more stable it should be. If it drops down to 160 again in this setup it means the problem is likely external and would need a line fault raising.
