Administrators Netduma Fraser Posted January 28, 2023 Administrators Share Posted January 28, 2023 Have a run through this guide and see if it's able to help you get higher speeds: https://support.netduma.com/en/support/solutions/articles/16000076586-dumaos-optimal-settings-guide-maximum-bandwidth-speeds Link to comment Share on other sites More sharing options...

David marin Posted January 28, 2023 Author Share Posted January 28, 2023 Yes, I connected everything to the R2 Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted January 28, 2023 Administrators Share Posted January 28, 2023 Okay great, make sure the ISP router is in modem mode or has the R2 in its DMZ and you'll get the best speeds through the R2 that is possible. You can also disable the protection options in WAN Settings and that will boost the speed slightly as well. Link to comment Share on other sites More sharing options...
David marin Posted January 28, 2023 Author Share Posted January 28, 2023 Okay I will try tomorrow the isp modem is in a modem mode but I will try DMZ because I will like have QoS enable Link to comment Share on other sites More sharing options...

It is unlikely you will get max speeds with QoS also enabled. Link to comment Share on other sites More sharing options...
David marin Posted January 28, 2023 Author Share Posted January 28, 2023 Then it’s better have the QoS disabled? Link to comment Share on other sites More sharing options...

If you want to have full speeds then yes, given your speeds as well it will be harder for bufferbloat to affect you so as long as you don't have any downloads happening while gaming you should be okay!
