Upload latency

Hello,

I'm experiencing problems on video/audio calls and online gaming. Was running speed tests to possible see a reason, one thing catched my eye is upload latency? Could this be an issue? I've checked at work and asked friends to check their and all of them has it below 50, mine is over 1000? I tried runing tests on my PC connected by wire and on a phone wifi - results are pretty much same with over a 1000 in upload latency.

    Hmm you have a hub 5x... but as expected your latency looks to spike when you max the bandwidth out due to rate limiting by VM. To fix latency spike at load you will need your own router with BWM or QoS to rate limit under VM rate limit for low latency.

    You will also have to double NAT and NOT connect ANYTHING to the hub 5x other then your router.

    I wouldn't put it past VM to have a bigger buffer for rate limiting on a low package speed for latency to spike high at load....

      It's highly unlikely gaming and video/audio calls are saturating 27 - 28Mbps upload.

        Having OneDrive syncing, Teams open and a video call running easily consumes this speed, so I call it defect from VM side, as upload ping shouldn't be nowhere near I'm getting.

      And is there any other options? Or adding another router and having double NAT is the only option?

        Really is the only option I mean besides more upload speed where the buffer VM rate limit is closer to the right size.

        Double NAT will mostly fine for your use case DDNS support on a 3rd party may not work but likely you don't use that and other things which VM have caused by there router mode anyway so you can't really fix what VM have broken but doing your own rate limiting under VM poor rate limit is something you can do.

      That sound a bit ridiculous what either i get high latency or I have to buy and use my own router... Could you please drop me any example of router i would need? Would i still be able to use wifi from VM router? And another ridiculous thing is that users on forum knows more than VM "technicians"

        Be wary of adding another Router to a Hub 5x.

        The resulting Double NAT brings an array of well documented problems.

    Post a screen shot of the Full Test from Realspeed so we can see if the high Latency and Jitter are a service problem to the VM Hub, or if the issue is between the VM Hub and your kit.

  • On top of this, I had an technician visit couple days ago, he replaced hub and a wire from "socket" to a hub, it didn't helped. He booked other person to come to change a wire from outside to a socket inside. Just wondering if this will help or i should cancel this and sort this issue somehow differently?
