Just before Xmas I was getting c480 mbps via speed test however since Xmas it’s been c100 mbps.
I’ve restated and reset box but no improvement.
Any ideas welcome.
Is this on both wired and wireless devices?
Could you access your router using http://192.168.0.1/ or http://192.168.100.1 for modem mode. Log in, select the 'Advanced settings / Tools / Network status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs? Please copy/paste this data as text, split between multiple posts (Sometimes you have to click 'Post' twice due to an error message).
