So I've just upgraded from Virgins 350mbps to Gig1, I've installed my new hub following the instructions. On the old hub was a 6db for the coaxial cable I assume its a signal booster. Anyways I've kept that connected to the new hub. My speed all day have been around 300mbps to 400mpbs. I have called virgin who has said there is work going on in my area however I'm very skeptical and believe there may be a deeper issue as to why my speeds are so slow. Does anyone have any help or advice please? Thanks.
