I have a new Hub 4 on the 1gig contract. Connected in Modem mode to Netgear Orbi. Over the last year have had consistent results on Orbi speed test of 600Mpbs down, 30Mbps up, which was ok for M600. Now I have upgraded to 1gig, the upload speed has increased to 50Mbps, but the download has stayed at 600-700mbps, below the minimum and far below the average quoted.
Virginmedia support has directed me here. Any ideas?
