Hi,
I can see the speeds have been fluctuating, and the SNR (Signal to Noise Ratio) on your line has risen.
Can you check the home phone, see if there is a clear dial tone. Dial 0 and listen for any noise or crackling on the line and let me know if the line is clear.
Also, check if you have a Test Socket and if so, connect the router / filter to this and see if the speeds improve.
Thanks
Karl.
