Fibre speed slowed down.

[#1]

Over the last week,  I have been doing speed tests, and last week Ive been getting 57mbits via wifi.  This week my connection has not been able to get 50mbits. (wifi)
My BT profile is 66mbits.  and The ATCUAL data transfer on BT hub pages is 58mbits.  It was previously 160mbits.
Please can someone prom PN change it back?
I have previously disconnected the Modem and Router due to decorating the hall.  I have done the usual change WIFI channels as well.

The speedtest result

Issue sorted .
BT engineer went to install someone elses fibre,  and I asked him if he could chck whats wrong.  He fiddled around the master socket and apparently a cable came loose and he said he will look at the exchange to see the speed status of my line. 
The biscuits worked 
The line is running even FASTER.  and I am achieving 61 mbits via WIFI and 65mbit via Ethernet!!
So internet is faster than before!
