I am currently on a M600 broadband package and everything has been working fine up until about two weeks ago when I started noticing lag during online games at the start intermittently but has gradually got worse. Any time I have done a speed test I am always receiving these speeds consistently. However, even with these speeds any online game is very laggy and borderline un-playable.
I am using a wired setup and this issue is happening on multiple devices.
Please see below - any help with this would be appreciated
