Yes, contacted VM to upgrade to Vivid 350 yesterday as I was missing the 20Mbps upload I had previously (all computers in the house backup offsite to Backblaze, and I also have a VPN server running here so I can remote back into my home network), and when the new config file was pushed it upgraded me at the same time - as can be seen from the following network log entries:

2018-04-19 23:32:37.00	notice	SW Download INIT - Via Config file
2018-04-19 23:41:14.00	notice	SW download Successful - Via Config file

I'm still on 20 bonded channels though, as I'm pretty sure I'm the only house in the street connected, and uptake of VM isn't massive, as we also have full whack 80/20 FTTC available throughout the estate. It was a project lightning infill as the top end of the estate, and most estates around us already had VM, so could just be I'm on a super empty segment!

Having a decent router, with decent firmware, behind also helps a little I believe.


Possibly for the internal connection to the outside world and maybe to reduce the loading on the hub but I don't think it makes a huge difference to the BQM. I've had 3 different routers behind my hub at various times, one of which was a business grade multiwan router, and there's very little difference in them. 

The biggest difference I get on mine is when I go from modem mode to router mode on the hub.. I get less yellow, the same top end for the blue but a higher base ping. So where the green area is pretty flat in modem mode, it follows the blue in router mode. I've got a hunch that my current problem is a dodgy hub (more dodgy than the usual) but so far they've never tried changing it out. The last engineer saying it was all "within spec"....

My results look much more like your BT line.

I am verging on believeing they have actually improved matters above ICMP only.

Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

I certainly think there are improvements beyond ICMP, whether there are still performance issues that are less obvious remains to be seen.

There are so many knobs and levers that can be tweaked on Linux running on a modern SoC - for instance, the R7800 that I use has had some issues with odd latency spikes on the stock firmware AND OpenWRT - however - the latest development version (which I'm running) has had some patches applied that have stopped them altogether.

Still, should never have been an issue in the first place, but happy I'm on the new firmware and it seems to alleviate my issues. I'll be doing a lot of video conferencing next week (I went into the office today, of all days!) so I'll have a better idea then.

Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

Just wanted to chime in on my experiences more recently.

I've always said that I haven't noticed any latency drops, but I did perform tests before and I was getting the odd large spike between myself and the modem, via my R7800. Also my BQM used to be massive spikes, same as everyone, I just wasn't seeing the effect in games. Now I have the new firmware (well, have had for about a month or more) and my BQM shows like this:

Also worth mentioning I'm a single user, with 2 devices at most at any one time, on 350/20, with a brand new line installed. Not sure how many of the people at my neighbourhood are on Virgin either.

Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

So after 17.5 years with Ntl/Virgin, I finally called it a day.

I have 25 days days left comparing my 38mb Sky (Now Tv) Fibre service to my 100mb Virgin Cable.

So far its a solid 37mb and great latency from Sky Fibre. Noting that we high high Virgin utilisation on our estate, which definitely affects Virgins performance.

Anyway...for this thread I've adding my data point (SH3 on old firmware):

These recent graphs are making me optimistic - just need the new firmware myself now. Queue multiple fruitless factory resets and power re-cycles this weekend....Smiley Sad


I kept doing this, but looking at the network log on my hub, the upgrade was triggered by the switch to Vivid 350 - what tier are you on? It could be that they're only trying it out with 350 customers as they will usually be on more bonded channels, and hence highlight the problem more.


Tried a re-cycle and factory reset earlier  - still on 116V.  200 is highest VM package in my area/postcode

Oh and I'm on 24 channels - so if one of the VM mods can get me prioritised for the new firmware I'd be extremely grateful !

^^^ Good luck with that I have been on 24 downstream channels for months and also have possibly one of the worst connections to the Virgin Network and they STILL have not given me ANY test firmware just look at the state of my BQM.

My area is no longer taking on new customers and max speeds are capped at 200/20 even though I can cross over the road and get 350/20 due to me being on the fringe of two CMTS areas.

My BQM is not as bad as yours....e.g. last night 2 PS4s were being used and watched films on Now TV & Netflix with only a slight bump in the blue as you can see.  Used to be worse but luckily there were some network improvements earlier this year
