I've been in FibreX for about 6 months. I'm on a plan with 200 Mbps down and 20 Mbps up.
Using my own routers (Linksys EA8500 and Netgear Orbi) the best download speed that I can get over Ethernet (plugged directly into the routers) is only 75 Mbps down. I do get the full 20 Mbps up. This happens all the time (independent of time of the day) and seems to consistently peak out around the 75 mark (sometimes only 37 Mbps, which is suspiciously half of 75).
When using the Vodafone supplied HG659 speed tests get the full 200Mbps down and 20Mbps up. This suggests that there's a setting somewhere in the after-market routers that needs tweaking to unleash the full speed. The only setting that I've changed in the routers is VLAN taging to '10'.
Any ideas gratefully received. Thanks
