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.

Hmmm, thanks for checking. I might try to factory reset the Hub3 to see if that helps.

Just done a factory reset on the Hub3 and the speeds have jumped up - Not where they should be as guaranteed minimum is 258 Mbps:

Going to repost the stats since the reboot

I'm unimpressed by the downstream power levels. VM are cagey about what's permissible, and as low as -6 dBmV has been semi-formally muttered, but I often observe problems at the -5 level, added to which power levels run from -1.7 to -5.4 which is a bit on the rangey side for my liking.
Hang on and see what the forum staff advise - if they can't offer a solution then you'll need to read and invoke the VM minimum speed guarantee, which broadly speaking involves you running tests until you can show a minimum speed below the relevant threshold at least once on three consecutive days.

Cheers Andrew, I'll be running them quite often to check.
I've added more stats now (got timed out for forum spam :D)

Just spoke to the tech team and they've done a remote connection to the Hub3, pushed a software change and I've seen a speed increase to 348mbps on wifi direct through the VM wifi channel
Hub3 is in Modem & Router mode, R8000 is in Access Point mode and I'm leaving it like that for 3 days whilst they monitor the HUb3 box. If it doesn't improve/gets worse, there is the offer of a new box on the table.
I'll post the stats of the box for records now as well.
