Very slow upload speed.

[fmac]

Yes Frazer. DMZ is pointing to WAN IP of R2. Also QoS is disabled in Movistar and also tested disabling QoS in R2. 

[Netduma Liam]

Are any devices using IPv6? If not can you please try disabling it from the WAN and LAN settings? 

[fmac]

Sorry Liam but I disable IPv6 always, so it is disabled since the very beginning. 

Just FYI, I work in Cybersecurity, installing perimetral firewalls. So that’s the reason why I’ve done most of the tests you’re proposing. 

[Netduma Fraser]

On the Windows PC in question, in network settings is it set to use random MAC addresses? If so can you disable that please and try again?

[fmac]

If I'm not wrong, this option is only available for WiFi devices, and I'm using ethernet.

[Netduma Fraser]

You're right, apologies! 

Could you try in the Windows 10 Network Adapter properties disabling QoS packet scheduler, in theory having the PC do QoS and the router (even if not enabled specifically) could reduce speeds

[fmac]

Changed and same result Fraser...

[Netduma Fraser]

Go to Update and Security on the PC, Advanced Options, Delivery Optimization, disable Allow downloads from other PCs. Try a speed test, if that is still slow then open Task Manager, then at the bottom click Open Resource Monitor, then in the Window that appears go to Network, sort by total, can you identify something up a lot of bandwidth? If so go back to Task Manager, Processes and end the process or quit the application manually then see if the speeds return.

[fmac]

"Allow downloads from other PCs" was already disable, so all the test I have done were with this setting off.

There is no process consuming my network bandwith. Remember that when I do the test with the Movistar router, there is no problem at all. The problem is only with the R2.

Honestly, I don't see that we are making any progress.

[Netduma Fraser]

With QoS disabled and other devices working well there doesn't seem to be any logical explanation as to why this device in particular can't get higher speeds. Have you done any manual port forwarding or anything like that towards other devices? 

[fmac]

The only port forwarding is the DMZ, configured to redirect all trafic to the R2.

In the R2 there is one NAT port, 3074 TCP&UDP pointing to my PC. And as you know this can't affect upload speeds.

[Netduma Fraser]

Could you disconnect all your other devices except that one PC and see if the speeds are improved? Might be with QoS disabled that other devices are taking bandwidth away from it, that's the only reasonable explanation I can see at the moment.

[fmac]

The scenario you're describes is one of the first things we tested.

Also remember that when I have several endpoints behind the R2, only this PC has the problem. Other ones have acceptable upload speeds.

[Netduma Fraser]

I don't think there is anything else I can advise. We can organize a replacement if you would like, that could help potentially if its a fault. If you want to do that email [email protected] with a link to this topic and your order number please.

[fmac]

Is there any place where I can check the conditions for this replacement? I wouldn't like to wait again more than 2 months for the new R2 and in the meantime be empty-handed.

[Netduma Fraser]

You can find the details at netduma.com/terms, you wouldn't be waiting that long
