Does the netduma throttle your speeds.....


Recommended Posts

I have  a Virgin super hub in router mode. When I test the speeds its usually around 50 down 7.5 up. When I hook up the Netduma it goes doen to 4 down and 1.8 up! Is this right? I have it wired with a Cat 6 cable.


Also when I'm in game it keeps connecting me with a server/host which I have repeatedly tried to deny, but to no avail. Even when I take the geo filter down to the lowest level it still puts me in the same server.  I have left a multitude of games because the ping was fluctuating between 40-120ms. 


I have only had the Netduma a few days and am now thinking I have wasted my money and time with it trying to get it right.


Anyone any ideas as to how to correct the connections.

Ok, so first of all, if your not already, upgrade to the latest stable version (1.03.2). As the Wiki is down I will explain here hoe to do it, please follow instructions carefully so you don't brick your router :)


 - Download this file.

 - Go to upgrade section of router then to the advanced section

 - Browse for the file and select the file you just downloaded.

 - Keep check version and preserve settings ticked.

 - Press upgrade and wait until router beeps

 - You are not upgraded to latest version!


Ok, so back to your original question about does the Netduma cap your connection. The answer is yes, if you want it to. When your doing the tests, first of all make sure it is done on a wired connection; not wireless. Secondly make sure that under congestion control, share excess is ticked and the sliders are on 100% (these are what cap your connection).


For people above 60Mbps, there are additional settings that need to be changed. As your speeds are below this threshold, it should not be necessary for you to change these - please see if the above recommendations increase the speed test :)


Onto your second question. To be able to block a host, you have to have the "update" button in the dialogue. Some hosts do not have this button because it is a dedicated server and the Netduma does not allow you to block dedicated servers. Do avoid the dedicated servers, you must either decrease the size of your GeoFilter or move your home location so that you avoid the dedicated server.


I hope that this has answered your questions! If you have anymore just as away :) By the way, once you get it working, I'm sure you will change your mind about wasting your money, believe me :)


Let us know how you get on with this :)

for the geofilter: use strickt mode "ticked", PA set to "0" + you have to wait 2min before the Allow&Deny Feature does it.


Anti-Flood: 1st > reset distribution, share excess ticked, all set to 100%, use Preemptive mode and then do the speedtest again.


maybe this helps a bit.

Hi Crossy, thanks for that advice. I have the latest firmware, so the router tells me, I have had the sliders set at 70% during the time I am gaming, and return them back to 100% after, so I will try leaving them at 100%.


I will persevere with it and see how I get on with it, but there does seem to be a lot of conflicting advice on the forums, so I suppose it's what works for your set up

Just to check, at the moment the one-click upgrade doesn't work as it is being more thoroughly tested. To check if you have the latest version, scroll to the bottom of the page and see what the version number is. If it isn't 1.03.2 then it isn't the latest and you will need to follow the steps in my original post :) I want sure if it was the one-click upgrade that was telling you that you were on the latest version or it was when you were actually pressing upgrade on advanced upgrade :) You might have been one of the first people to have the new version pre-installed :)


Also, I'm in chat (as usual) so if you want any help setting up or any advice pop in and I'll be happy to lend you a hand getting sorted e.g sorting out your speeds, getting open NAT or whatever else you need :) You can get in chat from here or the button in top right of all the pages!

I would not say its conflicting advice, you have maybe picked it up wrong.


100% is so you have full bandwidth thats why jaycee suggested you do this , have the sliders at 70% if others are using the network while you game :)

Hi Crossy, my router says I am on version 1.03.3 so I think it's up to date. I will try and tweek the settings a bit when I am gaming again, but again thanks for your assistance, and to others that have helped as well.

I see when you have your congestion control on you have 4 down and 1.8 up , this would suggest you may not have not put your true download and upload speeds in to the congestion control


Click set bandwidth and fill on your true download speeds , not the isps up to if you have not already.

Also if you are getting ping spikes do a internet diagnostic test from the duma and show us the results , cheers :)

How do I do a internet diagnostic test? As far as the speeds go I do a speed test by Okla on the laptop, and then check the speeds on the games console before I put the bandwith in.  To be perfectly honest I was having better games before i connected the duma to my syestem.  Its possibly/probably me that hasn't found the optimum settings yet

the test stated I had exceptional jitter and ping but no packet loss! at least something was ok.  I mean it just could be COD AW that is awful, but I usually get a couple of decent games, they have all been bad the last few days..

Hi Macca,


Sorry support will be slower this week because we're at the gadget show.


Firstly its almost impossible to have a worst experience with the duma even if its misconfigured because there is no additional latency. But we are here to help.


There are two separate things you're discussing that are often confused: bandwidth and latency. Bandwidth almost has nothing to do with the game quality its all about latency. Can you do a speedtest on a wired connection please. You're paying for 50mbits so you can easily achieve that.


You have to go to "Congestion Control". Then click "Set Bandwidth" and put in your speeds which are: 50 down and 7.5 up. Then click update. Go back to "Congestion Control" page and make sure anti-flood is set to 100%. You should now get full speed.


To help with latency there are quite a few steps. The first we suggest is set your anti-flood to 70% each way(only when gaming) this stops other devices/people at your home making you lag.


The next step is to setup your geo-filter, have you managed to do that? Can you take a screenshot please and we can assist.

Hi Iain,

Everytime I do a speed test it has changed, so I do it just before I am about to start gaming, and I test it on a wired connection, I then check when I am online with through the network on my games consul. I then put in the readings which have fluctuated from the high numbers to as low as 1mbps to 335 kbps depending on the time of day


I usually have my congestion control set to 100% as there is only me using the network, as no one else is home.  I have set my geo filter to around 100 kms and set my home location in Scotland although I live in the North West.

Hey Macca, please do not pay any attention to the network tests on the consoles. They are not very accurate at all. If you notice the ping is quite high, this is because they use their own server to test. A wired PC test to speedtest.net or some other reputable site should be what you pay attention to. Do a speedtest from the PC and input these into the bandwidth settings on the R1.


Your congestion control is fine at 100% but do you mean 1000km for the Geo filter or 100km? Setting it to 100 especially in Scotland is way too low to really get any good games at all. I'd recommend setting your location to the middle of the UK and putting the distance to about 1000km and have ping assist at around 30-50ms.

Hi, Fraser

Sorry, I meant a 1000kms, my ping assist is set at 30, I will do a wired test again and in put the numbers, and ignore the console readings, and see how it goes


Thanks for all the help from eveyone

Upload of 0.85 seems low considering you would expect it to be nearer 7.5 as stated in your op?


You could try going back to Congestion Control, drag the Upload cap slider up and down a few times and leave it at 100%. This may unstick your upload, if it is indeed stuck, and get you nearer what you'd expect.


Underneath the sliders is Device Prioritisation. Make sure Share excess is ticked, hit Reset Distribution button, then Update Distribution and try another speed test.


Hope it helps :)
