Speed drop following first day

[#1]

Confirmed this morning. 
Full network now re-attached (inc gig switch and NAS) and all computers seem to be getting a stable 73mb download 18mb upload with an occasional blip down to 68down, 18up.
All traffic types working nicely, perhaps I wont need a new router afterall

That looks better! Not to sure what happened there but everything seems fine on you line.
Let me know if anything changes.
