200M : Dramatic drop in speed since 200mps upgrade

[General Maximus]

nope, your upload speed is at its maximum of 12mbits, it is your downstream at 3.8mbits which is extremely peculiar and definitely needs looking at.

Did they do any speed tests at all? They're still supposed to help diagnose slow speeds, even if there's no issues in the area.

They did do a test yes. They found nothing wrong. I logged into my work machine remotely and we use 150Mb Virgin at work (my works is approx 10 miles from me) and the same issue happens there! Speeds were around 8 - 20Mbps it changes in that range a lot.

I think that confirms that it is indeed just congestion. I will phone Virgin again tonight when the Internet slows down again because they may not be aware of congestion somewhere along the network.

Sorry I'm confused. If they ran a speed test and got 20mbps, that's a problem. But if they ran a speed test and got 200Mbps, then yes everything is fine - which did they do?

And just to be clear, I mean they ran a speed test FROM YOUR MACHINE, not some (non-existent) speed test they can run from their own side.

Forget about your work machine, that is not in scope and "logging into it" (Assuming a VPN) is a different can of variables.

I did the speed tests multiple times on wired and wireless. Wireless makes no difference for me. I am connected at 600Mbps Wirelessly. They did some "tests" there end which reset the modem into router mode and found no issues...

For reference I use this equipment:
https://www.ubnt.com/edgemax/edgerouter-lite/

https://www.ubnt.com/unifi/unifi-ap-ac-pro/

and a Cisco sg300 gigabit switch.

So my home setup is perfectly capable of 200Mbps wired and wirelessly (to re-clarify I have speed tested in both scenarios).

and no I didn't use VPN at work. I logged into the machine remotely and ran the speed test physically on the machine taking into account that I am actually using Teamviewer could possibly slow the connection down but not from 152 to 10 - 15 in download.

Anyhow last night I got 130 - 140Mbps which is acceptable to me during peak times.

Also on another note, why does YouTube load from a Virgin Media server? I assume its a "cache"? Any videos that load from there servers buffer constantly.. I found this by doing trace routes on certain YouTube videos.

you are getting your nickers in a twist dude and you need to understand what you are talking otherwise VM aren't going to take you seriously if they think you don't understand what is happening.
Firstly, a single device may be able to connect to your access point at 600mbits but you by no means have a 600mbit lan connection between all devices and definitely do not have a 600mbit wan connection. Any wireless speed test you do (e.g. if you download the speedtest.net app on your phone) will run the test from one point to another. In this case it will be from your phone, through the wireless access point, through the router, through the shub to your CMTS, all the way through VM's network and finally to the speed test server. The only part of that path which is 600mbits is the first hop to the wireless access point. If you are getting speed test results in excess of 200mbits then you are running some sort of test locally to test the connection to the access point and not your wan connection.
Secondly, teamviewer isn't going to impact any speed test result at all. The test isn't testing the quality of your connection between 3 devices; the device you are establishing the remote connection on, your home pc and the speed test server. When you instruct your pc to run a speed test the pc will run the test between itself and a remote server and you will see the result fed back to you. The quality of your team viewer connection is irrelevant and defo will in no way impact the result. The worse that can happen will be a slight delay in it starting the test and you seeing the result when it finished due to the slow connection.

its 600Mbps connected wireless and everything else from there is gigabit up the point of the WAN connection at 200Mbps. Everything is wired locally as gigabit even the AP.

So surely that singles out any LAN issue?

[General Maximus]

yes it does but you give the impression that you believe your wireless connection is 600mbits full stop and independent of wan restrictions and I wanted to make sure you understood where that 600mbit connection lies in your network, how the speed test operates and the limitations of hardware or routers on any given path.

As an example, you ran a speed test from your phone and the connection from your phone to the access point is 600mbits, the connection from the access point to the router is 1gbit, the wan connection running across VM's network is 200mbits and the link going from VM to the external hosted server is 10mbits, then that entire connection runs at the speed of the slowest link and the speed test result will come back at 10mbits.

Yes I understand that hence why I did use multiple speed test websites and different scenarios to cover everything.

Teamviewer will use a little bandwidth itself to deliver the screen, that's what the guy was referring to when he mentioned a small impact.

It will defo impact the result unless the packets are getting to his home from the remote office via another connection.

Yes, Google Global Cache.

Google Global Cache (GGC) enables your company to optimize network infrastructure costs associated with delivering Google and YouTube content to your users by serving this content from inside your network.

GGC is implemented as a set of servers deployed in your datacenter, remotely managed by Google. The number of servers deployed will depend on the bandwidth demands of your users and the number of locations at which you chose to install GGC nodes.

Interesting. There is no way your work is going to be sharing any access network with your home at that distance, so the problem is either in a router chassis or a backhaul link, or there's coincidentally congestion on both optical nodes.

http://www.thinkbroadband.com/ping might be useful. As I'm sure you're aware congestion will tend to show up as increased ping and jitter, especially if it's on the backhaul.

Forget all about your home networking equipment (Which is good stuff!) and forget about anything to do with wireless. It's not Virgin's responsibility to check out your home network and anything after the hub is not their concern. You need to do a wired speed test from the hub - nothing else in the way and nothing wireless.

If I had a pound for every time someone was absolutely completely sure it wasn't their equipment and it was absolutely definitely Virgin's fault, I could retire early.

Note that I'm not saying your equipment is at fault, just that Virgin gets that a lot and if you refuse to budge on it, they (quite rightfully in my opinion) will refuse to help you as it's not their responsibility. They need to see a speed test from your end, wired into the superhub, to diagnose a fault.
