Assuming you've gone out then you can see how much better your connection is without your router involved, I'd try a new, decent router.

Just returned, it seems that most the problem was the router, must be very unable to keep up performance.

I have arranged for it to be returned and intend to purchase a TP-Link Archer C6 as I'm already using one elsewhere with better results.

I think some testing is required, going to look for a 10GB test download to see how latency is affected.

So just completed a 10GB test download, as soon as the download started I started get very varied latency and packet loss started to occur....

Is this because I'm directly connecting to the Modem and there is no QOS to prioritise other connections.

Exactly normal, if you max out your connection speed, the latency of the ICMP ECHO (a ping) will go up as the connection is saturated.

If you have a router attached to the ONT, then you have a device that can share the connection, however one user pulling down something huge (e.g. your 10GB) will case other users to experience delays.

If you have other users that need to use the network for small size items, but it is important they get through (e.g. VoIP) then enabling a QoS policy on your router may help.

Maxing out the upload is the usual way to annoy other users, which is why those on ADSL with under 1 Mbps upload, or those on FTTC with really slow upload, e.g. 4 Mbps, have problems when families are all trying to do video calls from home.

OK, well I'll look at purchasing another router with QOS I suppose and see how it goes but I'm not exactly over the moon about the idle performance of this connection I've had lower baseline pings with both Cable and DSL services.

Nearly all routers / modems will implement some basic level of traffic prioritisation, even if its not user configurable.

As a result, ping packets are nearly always assigned the lowest priority over TCP and UDP, therefore when a device is under load it is normal for ping times to increase as the packets are put to the back of the queue.

Until I get a replacement router I'm using the connection directly connected to my Desktop.

Well it is a lot better than my (4G) connection!

Well I'd hope so! :/

Depending which 4G network you are using, you may not be pinging your device, but a CGNAT gateway. Also variable ping latency over 4G doesn't surprise me, due to the way radio based systems work is completely different to fixed line.

So I've today connected a Netgear R6260 and seen an improvement already in My Broadband Ping

I'm about to go out again so will launch a 10GB download like last time and see if there's an improvement.
