Let us know how it goes, e.g. the downstream you get and how consistent.

Sure, will do.

So, a little underwhelmed at the download speeds i'm getting. Hub4 in modem mode and getting 264mbps max. Upload seems good at 52.87mpbs.

I'm hoping it improves as the results indicate i'm getting less than I was on the 500mb package.

I'd suggest running the Samknows test at www.samknows.com/realspeed when the Hub 4 is in router mode.

That will tell you what speed you're getting to the Hub itself rather than in between a internal network device and the Speedtest.

Ok, I'll give this a try this afternoon. Thanks

Great. That certainly seems to have done the trick and now getting upwards of 650mbps on download. This is with my desktop machine plugged directly into the Hub4.

Now need to try and figure out why I'm not getting similar speeds when connected via a gigabit switch from my own r8000 router.

Edit - just ran the speedtest again from your link and it's maxing at 1084mpbs on download and 680mbps on upload!

Thanks again!

680mbps on Upload?

You can't get 680Mbs on upstream. 53Mb is the very best you can get.

On Samknows you can get something like 1.17Gb downstream although 1.2Gb is technically possible.
With Hub4 in modem mode, your R8000 should get significantly over 900Mb, although I don't know exactly what its WAN to LAN throughput maxes at. Things that may stop you getting >900Mb include a faulty ethernet cable or a faulty switch or something else in the house using bandwidth. Another possibility is that you have QoS enabled in the R8000. This is of no benefit on a 1GB connection. It may peg back the maximum down speed on certain devices to as low as 400Mb.

Other possibilities include the processor capacity of your PC. Speed tests are processor hungry. A slow processor can result in an unstable test with wildly varying results. You can check this if you watch your processor usage during a speed test. If it goes up to 95% usage your speed test result might be affected.

Others here may think I am barking up the wrong tree and may have other suggestions.

Yeah, sorry I was getting away.

Speed to Virgin Media Hub 4 was 1072mbps
Speed to computer was 599mbps

Upload is 52mbps

I'll have a check over everything. Cheers

Yes, you have roughly a 340Mb shortfall there. Check some of my suggestions. Given that the R7000 had a WAN - LAN throughput of 931Mb . The R7800 managed 941Mb. Surely the R8000 has similar or better. I think we can discount your router as being the problem over wired connection. Good luck checking out the other options.

If you have an intervening switch between your router and PC, can you take that out of the system, just to see what difference it makes? Are the ends of your Ethernet cables properly secure? One of my long Ethernet cables, one that runs to the attic, developed a fault so was only providing about 500Mb to upstairs devices. Sometimes it only showed as a 100Mb connection on the router network data page. My mate, a network expert and installer, tested and fixed it for me by replacing the end connectors.

Throughput for consumer routers does vary with firmware and is also heavily dependant on what features you have on, if you want 1gb you probably need to turn off QoS, IDS/IPS, DPI, etc.

If you want something to do well over 1Gbps, you need something like the Ubiquiti UDM-Pro which can do 3.5Gbps (has SFP+ 10G WAN and LAN) with all the bells and whistles turned on, or 8Gbps with just DPI turned on.

Just remember that the hub4 only has gigabit ethernet, so at least for today there's no way of using another router at > ~950MBps.

rtho782 · 10-09-2020, 11:02

Yeah, I realise that, the Hub4.0 is an idiotic decision by VM, every other SH has been used across various speed tiers during it's service life, the Hub4.0 can't even keep up with the provisioning of the launch service, let alone whatever we see in future.

Eventually VM will need to wake up and replace it with something with either multigig copper ports or an SFP+ cage.

There are better DOCSIS modem options about, if only VM allowed 3rd party modems.

Kushan · 10-09-2020, 11:14

I think it's a classic example of VM being cheap. Plus it's only an issue if you don't use modem mode. Most of VM's customers just use the hub in hub mode.

Of course, I'd argue that the kinds of people taking the gig1 service are the kinds of people more likely to use their own router as well.

In my cynical mind, DOCSIS3.1 is less about providing faster speeds to the prosumer and more about Virgin being able to squeeze more out of their network. It's expensive to roll out, but once done and everyone's on it, they'll have a lot more bandwidth to play with. Most of VM's customers are on the lower tiers, they don't care so much about fast speeds, just ample rool in the pipes.

Virgin will eventually be pushing the Hub4 out to every single person, the cost over millions of customers probably offsets the cost of having to introduce a hub5 down the line for those afformentioned "prosumers".

rtho782 · 10-09-2020, 12:15

Even if I used the Hub4 in Hub mode, I still wouldn't use more than 1Gbps as most of my usage would be from a single device at a time, be it Steam on my main PC or whatever is downloading on my unraid server. I guess for some, there will be multiple devices connected over separate ethernet ports without a switch inbetween each using a load of bandwidth but I'd bet that's pretty uncommon at home.

I do agree they are being cheap, but they didn't have to do an NbaseT port, an SFP+ cage would have been very cheap to have and would allow people the option of NbaseT or MMF/SMF/DAC etc.

I'm not actually sure any of the OEMs make a modem with 10GbE yet though to be honest, so it might not be VM's fault. Perhaps VM Business will come out with something better, or maybe it will be a wait for SH5.0 thing.

Honestly, the sooner Cityfibre finish digging up my town the better!

At the time LG sourced the Hub 4 hardware from Arris, there will have been limited options available for DOCSIS 3.1 kit. The same Hub is installed in all LG D3.1 deployments, it's not unique hardware to Virgin Media even if the black version is.

Arris have only recently introduced Wi-Fi 6 and 2.5Gig Ethernet hardware to their gateways as far as I know.
