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.

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
Well, keep an eye on it. This remote kick up the arts that VM claim they do often doesn't seem to fix problems for any length of time, and that's unsurprising if the fault is line noise or a manky connector. Your latest stats still show rather poor downstream power, plus far too many post-RS errors. Even in small numbers, post-RS errors are really bad for latency and speed.
I could be wrong and hopefully am, but I suspect you'll see speeds deteriorate again.

Cheers Andrew,
That's what I'm expecting as well in all honesty but willing to give them the benefit of the doubt.
On a plus note, the tech team actually listened to me, my setup and my efforts to correct it and didn't have me disconnect or reboot the hub3 etc which was what I was dreading when I rang up to complain.
Will leave the setup exactly as is and see what the crack is on Sunday night

Thanks for your post and updates, Goosh,
Let us know how it goes with your connection.
Cheers,

Hi Corey_C,
I've achieved some increases in speed, but not consistent at all - very hit and miss and not at all above the minimum guarantee. Unfortunately, my whole housing estate was offline this morning so I was unable to test further as I'm at work (saving grace).
I'll reboot the router when I get home and see what the state of play is but if theres no improvement, I may have to escalate it further.
Thanks,

Hi Goosh
Do try the reboot and let us know.
Best,

Hi John,
I'm still getting below par speeds and no consistant speeds. I did achieve 443 Mbps on VM wifi when I was stood next to the hub but this is below the guaranteed speed. The current stats are:
