Slow Speeds after changing to Netduma Router

Hi,

I've been seeing half of speeds after changing to Netduma Router R2... I tried this KBs before posting: 

https://support.netduma.com/support/solutions/articles/16000076586-dumaos-optimal-settings-guide-maximum-bandwidth-speeds 

https://support.netduma.com/support/solutions/articles/16000123155-why-can-t-i-get-full-speeds-from-my-dumaos-router-

(Disabling QOS, disabling IPV6...)

I don't really want to re enable the ISP's router, it defeats the purpose of getting a 200 euros router... I tried with my old Asus and the speeds are not as slow as on Netduma. 

The speed tests are both by cable on a 3090 PC and on the own Router speed test tool.

Welcome to the forum!

What speeds do you get from your ISP? What speeds do you get from a third-party speed test such as speedtest.net when you're connected directly to the ISP? What speeds do you get through the same speed test when you're connected via the R2?

Thank you! 

So when on the ISP is 950 mbps for 1GBps. When on netduma i just get 450 to 500 mbps https://www.speedtest.net/es/result/14381177925

Do you know if your ISP requires you to use PPPoE, VLAN or DHCP identifiers in order for you to get connected to the internet? If they do, can you configure these on the ISP modem instead of the R2, so the R2 can then simply connect to the modem via DHCP?

 So it requires PPPoe Connection under VLAN 6, same configuration is made on Asus router with regular speeds there, but not on Netduma

OK, and do you have the option with your ISP equipment to configure PPPoE and VLAN there, then connect the R2 via DHCP? We have seen some issues with the R2 and PPPoE/VLAN in the past, so if doing this resolves the problem for you, it tells us that this is where the problem lies.

Sorry what do you mean, having the ISPs router as router and the Netduma router as Access Point / Switch?

The R2 would still be in router mode, you don't need to do anything on the R2, just remove the PPPoE/VLAN details on it and put them on the ISP router instead. If that works then great and we can give you steps to prevent a double NAT situation.

So I removed VLAN 6 PPOE, changed the port from the blue one to use one of the yellows (Switch) changed the IP address so it doesn't conflict with the router from the ISP and the speeds are back to what they should be https://www.speedtest.net/result/14392067751 950 download.

Okay brilliant but you should still have the R2 blue port connected to the ISP router LAN port so the R2 runs properly

Hmm not quite mate, I had to change the cable that comes from the ISP router to one switch otherwise i won't have internet, plus the Geofilter doesn't work at all with this WORKAROUND, it's far from running properly to me...

By switch are you referring to the ethernet ports? If so that's fine but it should be connected to the R2 blue/internet port not the yellow/LAN ports for the R2 to work correctly, once done if you don't have internet give the ISP router a reboot, then reboot the R2, wait 2 minutes then access and test.

so I wanted to chime in here. from what I can tell, the whole auto-detect bandwidth and connection benchmark are clearly affected by whatever servers the R2 is connecting to run these tests. the R2 comes no where close to being accurate on detecting bandwidth speeds. when these servers are corrected, it could change a lot of things for many users of DumaOS 3.
