I am using the M200 package and generally my experience has been positive, however recently I have been encountering a recurring issue when attempting to stream to Twitch resulting in repeated crashing of upload speeds from 6000kbps to almost zero, then spiking back up, etc. This results in dropped frames and at times this is averaging around 30% dropped frames, so I am unable to continue streaming. I have tried swapping cables, rebooting the router and other devices, etc. None of this helps while it is happening, and it's important to note that I was able to stream before perfectly on the same setup and no change has occurred on my end. I am in the NR2 postcode, if this helps. 

The automated help system wants to reset my router because I've disabled WiFi, however I have the WiFi disabled on the router for a reason (I use a separate mesh WiFi system for my WiFi) so I don't want to do that. I've worked in IT for 20+ years so I know it's not anything I'm doing wrong. Outside of the streaming issue, the connection is fine and I can accomplish all of my other use cases just fine. 

Thanks in advance for any help.

Just as an additional bit of info, this past issue looks very similar: https://community.virginmedia.com/t5/Gaming-Support/Twitch-Stream-Inconsistency/td-p/4892467

Have you tried a different DNS to Virgins default? Give Googles 8.8.8.8 a try or 1.1.1.1

Hi, do you mean on the router itself? I don't see that as an option anywhere on the web management UI. I'll try it on the streaming PC and report back.

Tried Cloudflare's DNS set on the streaming PC, seems to be better in a short trial, but I'll test a longer stream tomorrow and update with results.

Yeah unfortunately the superhubs don't have the option to change DNS which is a shame, but yeah as you have done you can set DNS on individual devices.
