About 2 weeks ago I upgraded to 1Gbps. I was previously on M600 and getting consistently over 550mbps downloads. I installed the Hub4, and every since have been getting slower downloads. I read on here that the Hub4 can take time to settle, so I have waited (in vain). The previous SH3 had a 10 db inline attenuator, which I have kept. I run the Hub4 in modem mode, but if I run it as a hub and then run samknows with my PC directly connected to the Hub4 by Cat6 I get this:
It seems my speed to the hub 4 is fine, but the hub 4 then gives me a lower speed than I got from my SH3 on M600 (by about 20%). Other speed checkers confirm that I cannot get more than ~440 mbps to a wired connection. The upload speed is consistently at expected level.
thanks for the reply. I have tried rebooting, switching between modem and hub mode and different cables. I will try a rest at some point, but I don't hold out much hope that will make a difference. Everything is the same as when I had M600 with a SH3 in modem mode, but the download speed is slower.
Thanks for organising the technician. He duly arrived and tested things.
He confirmed 1Gig to the Hub 4 but then found, as I did, that the speed to my PC was half that in modem mode through my Asus router, but SLOWER if the PC was directly connected to the Hub4 in hub mode using his Cat6 cable.
He found that download speed discrepancy odd and agreed to try a new Hub4, but that had the same effect. He left bemoaning the fact that VM do not supply their tech staff with a device that can confirm the speed coming out of the Hub4 when directly connected to it. He had no further suggestions other than it must be my equipment on the basis two hubs gave the same result. However, he could not demonstrate that the Hub4 delivered 1 gig.
The delay in posting this response is because I have been busy. I have replaced two 10-year-old NetGear gigabit switches with new ones, and also replaced Cat5 cables with Cat6 - the last one from the ground floor room where the Hub4 is up to my 2nd floor office today. These upgrades have changed nothing as regards download speeds from the Hub 4. My office laptop (HP Elitebook 840G5) typically downloads at ~300 Mbps on a wired connection (it gets 97 MBps file transfer from my NAS drive on the ground floor indicating the Cat6 is working). My Pixel 4a phone just got 450mbps (!) through wifi (I have a Mesh Wi-Fi network with Ethernet wired backhaul).
Something is throttling download speeds, but I am at a loss to work out what.
