Lower Speeds on Netduma R3 Compared to Fritz!Box 7490 (Vodafone over Deutsche Glasfaser - PPPoE)

[Maqiic]

Hi everyone,

I'm experiencing an issue with my Netduma R3 setup and would appreciate any support or advice.

Setup details:

• ISP: Vodafone (via Deutsche Glasfaser infrastructure)

• Connection type: FTTH

• Authentication: PPPoE

• VLAN ID: 7 - Set correctly (as required by Deutsche Glasfaser/Vodafone)

• Device: Netduma R3 (latest Early firmware)

• Alternative device: Fritz!Box 7490

When I connect using the Fritz!Box 7490, I get the full contracted speed of 1 Gbit/s down and 500 Mbit/s up. However, when using the Netduma R3 with the exact same PPPoE credentials and VLAN configuration, I only reach about 770 Mbit/s download, although the upload remains close to expected.

This suggests the issue lies with the Netduma R3 itself, possibly in how it handles PPPoE or VLAN tagging under high throughput conditions.

What I’ve tried so far:

• Verified PPPoE credentials and VLAN settings

• Ensured R3 is directly connected to the ONT/modem (no double NAT)

• Tested with and without QoS/Geo-Filter enabled

• Firmware is up to date

• No devices heavily using bandwidth during the test

• Speed tests conducted via wired connection (Cat 6 cable)
  
   

  Any input would be greatly appreciated. I really like the features of the Netduma R3 and would prefer to keep using it—if I can get it to deliver the full bandwidth.

  Thanks in advance!

Hi!

These are very good speeds behind PPPoE/Vlan with the R3! Welcome back!

VLAN and PPPoE are recurring topics, but the team ND is working on a solution.

For now, the best thing to do is let the modem/router manage the PPPoE/VLAN internet access and set the R3 to DHCP.

I work like this and I don't have double NAT!

We are aware speeds are slightly slower using PPPoE and we'll improve that if we can. Otherwise you can put the R3 in the exposed host on the Fritz instead and have the fritz handle PPPoE as mentioned above and then you should get better speeds through the R3.

Hi @Netduma Fraser & @Krush,

thanks a lot for the quick feedback!

Good to hear that this is a known topic and that improvements are being worked on regarding PPPoE performance on the R3. I’m definitely looking forward to future firmware updates in this regard.

I’ll test this setup and monitor both speed and latency.

If there are any beta updates or settings that could improve PPPoE handling on the R3 directly, I’d be happy to try them and provide feedback!

Thanks again – I appreciate the support!
