Hi all,
I upgraded to the M500 package from the M200 and the speeds have gotten worse! I've been reading a lot of the forum posts and I don't appear to be alone.
Background
My setup is a Hub3 in modem mode, plugged into a Netgear R8000 Nighthawk with firmware V1.0.4.76_10.1.82. This has been running perfectly for just over 2 years and is configured correctly - running in QoS mode with 1x 2.5ghz and 2x 5ghz channels, evenly split out and managed by device (I'm a gamer and streamer so this is highly important to me).
I upgraded to the M500 on the 15th September, the router was remotely rebooted by VM and I thought that was all that was needed. Having checked speedtest.net, there was no real change to my speeds (if anything it looked lower than before) so decided to wait a day or two.
On Sunday (19th September), I rebooted both the modem and router with a power cycle (10 minutes unplugged, cuppa, come back style :D) Still no improvement but an increase in my upload speed to 30Mbps (the 10% I've seen in other threads).
Test and Checks
So far I have done the following:
My SpeedTest results show the Upload increase instantly from the date of the upgrade too, but worse download speeds:
I've also setup a ThinkBroadband Monitor last night and I don't like the sea of red on the Packet Loss that the graph has given me:
Live graph here: https://www.thinkbroadband.com/broadband/monitoring/quality/share/a739504fa032a95f06bd986f9407a64886...
So far, I cannot get anywhere near the speeds I upgraded to and it's infuriating. I'm ready to call up and envoke my 14 day reverse on the contract upgrade.
Here are my Modem stats (of which I will admit I am clueless about):
Any help or advice would be appreciated as I am one-step away from factory resetting the modem and router which I don't want to do incase I lose all internet for a longer period of time than I can afford.

100% packet loss means one of two things: No internet connection on the IP address the BQM is configured for, or your router is not setup to respond to ICMP requests. I suspect the latter, although when swapping between modem and router mode the IP address changes (and may do also if you're doing protracted router or hub fiddling).
As for the rest of the post, I can't comment until the images are approved (always better to post as text), and even then any with IP or MAC addresses won;t get approved, and anything that is a screenshot is at risk of being illegible if the resolution of the image is low.
Not 100% of the time, but usually VM will say they can't check connection status in modem mode and then won't book a technician (if that's needed), so only until the problem is fixed I suggest hub back in router mode, put your own router in access point mode, and you shouldn't then need to change any device connections or wifi settings.
Or, just phone up to cancel in the cooling off period, that threat is often enough to get a technician assigned.

Thanks for the response @Andrew-G. You're right, ICMP was disabled on the R8000, I've set that up now to get clearer information from ThinkBroadband monitoring. I've setup the R8000 as an AP now as well just in case.
I'll post the details as individual replies now in the format @lotharmat asked too.
