Not achieving expected speeds with R1 using CC

[buddy love]

I just recieved my R1. I currently have 300Mbps internet with optimum online. I'm using an Arris TM1602 modem and the Netduma router. The Pc I am using to setup is Hardwired. When setting my bandwidth (300Mbps down/35Mbps up) I achieve these speeds no problem with the congestion bars at 100%. I am curretly on the 1.03.6h firmware. 

 

My issue seems to be with setting  Congestion Control bars. When they are moved my download speeds are only about 160-170mbps.  Doesnt matter what the settting is. I have tried 99% , 90%, and 70% of total bandwidth and I get the same speed results.  I have everything disabled in Miscellaneous except forTurbo mode and password enabled. I also Reset the distribution and Updated the distribution for all devices on my network . I also have Share excess enabled on both the Download and Upload. I am looking to control buffer bloat and get the maximum speeds I can doing so. 

 

I really do not understand why these percentages are not working properly . I have rebooted ,powered off the unit entirely and turned it back on. I even factory reset the R1 and reconfigured with the same results. 

 

Edit: I followed BIG__DOG suggestion but they did not work either. I successfully updated the firmware to the "j" version as well. I figured it couldn't hurt

 

Please Help.

Hi & welcome to the forum.

 

When I had this issue I set my sliders to 50% then I inputted my speeds I should be getting and when I clicked apply I did not allow the router to make changes for me when I was prompted. When you set your sliders back to 100% you will get full speeds and when you reduce them again they should be more accurate. Please maKe sure cookies are enabled also in misc settings or any changes you make may not be saved!

 

Please let us know if this fixed your issue.

Thank you for your suggestions but they did not produce correct results. I even went bit further than a normal speed test to test the issue im having. I wanted to see if the speeds would increase/decrease if i downloaded a large file, I logged into my battle.net account and reinstalled a game  about 10GB in size. I was clearly able to see that when I adjusted the CC bars to anything besides 100% my download speed was reduced in half while downloading.

Hi, welcome to the forum!

 

The reactive algorithm has a 30% buffer on it so even at 99% congestion control you'll lose about 30% bandwidth at times. That's why your speed test  are not giving you the bandwidth you would expect with only a 1% buffer. It is to ensure you do not experience any local congestion whenever your devices are downloading etc, and should still give you plenty of bandwidth for your home. I hope this makes helps

Hi Jack Thank you for your response.

 

A side note : I had my ISP increase my internet speeds recently, they were 200/35. Before they were increased, the CC % was spot on. I used to avg 170-180 with a 90% CC setting. Since the Increase, the speeds are cut nearly in half no matter how small an adjustment from 100%. In fact , they are nearly the same as they were before the I had them increased. 

 

I dont see why threes an issue since I increased speeds. Could it be issue or limitation of the device itself ? Its is what Im suspecting at this point.

Hi Buddy,

 

Have you adjusted the max bandwidth speeds on your router since the increase? Go to Device Manager and set a new bandwidth (and confirm you are happy for your setup to be auto-configured to your new speeds).

 

Are you getting full speeds at 100%? If yes, then it won't be a device limitation. Just a settings misconfiguration.

[buddy love]

I have adjusted these settings and 100% of my speeds.  I have followed the setup guide exactly as it states. 

[Netduma Admin]

I have adjusted these settings and 100% of my speeds.  I have followed the setup guide exactly as it states. 

 

So at 100% on both upload and download you are getting full speeds? What speeds are they exactly?

 

And then when you reduce to something like 90% you're actually seeing a much bigger drop than 10%?

[buddy love]

the speeds are about 315-320 Mbs down and 35-36 Mbs up at 100% CC.

When I set the CC at 90%, My speed are about 160Mbs Down and 31 Mbs Up. 

The upload seems to be correct but the download is way off .

 

I went one step further, I set the CC on both down and up  to 10%. I had correct readings for both . the were about 31 down and 3.6 up 

Looks like the download isnt accurate with any CC setting thats 60-99%. 

[Netduma Admin]

I think I might know what this is. Could click reset distribution on the Device Prioritization please. (Make sure you’re on the download) option. Also make sure share excess is checked. 

 

Then try again. Thanks. 

[buddy love]

tried that and no change . 

 

I also factory reset the modem and the netduma router all together and have only one PC connected to the network. 

The issue still remains .

Hmmm, ok. Strange one. Could you go do this please:

1. Go to >Settings >Miscellaneous and take a screenshot and post here (it's easier to upload to imgur)
2. Take a screenshot of your Congestion Control page and post here as well (set both sliders to 100%)

Thanks

I have the same problem as OP, I recently updated broadband from 200Mbps to 350Mbps and the Anti-flood down cap doesn't seem to work as expected.

 

I have 350/15 broadband and getting 380/16 with speedtest.net when up/down cap is 100% (Reactive). When I set down cap to 99% (Reactive) I get less than 170 down.

 

I have set 350/15 in Set Bandwidth

In Misc. Settings I only have Cookies and Turbo Mode checked

In CC I have reset distribution and updated distribution

I have one Hyper-traffic device configure for XBox Live

 

I tested with super turbo mode enabled on Misc. Settings and get the same results.

You may need to zoom in a bit in your browser. These did not come out as large as I thought they would.

I added the other devices back to my network. The ones that are labeled Livingroom and Bedroom are APs. I do not use the wireless aspect of the router. 

 

Desktop and x123 are pcs. x123 is a laptop.

the rest are cell phones, ShieldTv, Firesticks.

I too had this exact same issue with my R1 the two years I’ve owned it, but only when directly wired to my fiber optic line. If I threw my isp router in first then connected my r1 to it I would get full speeds. Not sure if you guys are both doing the same, but at least in my case my gaming was better off with the slower speeds and the R1 as my main router. I did however just upgrade to the XR500 a few days back and am now getting my full speeds, actually about 10 mb over with it ran the same way direct to my fiber box. Just thought I’d throw it out there as maybe it has to do with how some companies use fiber and the r1s ability to connect direct to it.

 

I also tried all the above and everything under the sun and never had any luck aside from how I mentioned above. Wasn5 a huge deal for me personally, just a bit annoying I was paying for a higher package so I didn’t work with the mods personally to attempt a fix.

Are you using PPPoE or IPv6 by any chance? As with the above advice, if you put a router in front of the R1 then try again does it work as expected?

I did the above as suggested. I'm assuming I'm waiting for a response about my settings.

Hi Buddy - this was the response to your test. Could you let us know the answers to Fraser's questions?

 

Thanks

[buddy love]

I am not using PPPOE or IPv6 . 

[Netduma Fraser]

Okay thanks, if you put a router in front of the R1 then try again does it work as expected?

How would I go about doing that ? I'm looking for solid instructions on settings but I don't see a topic relating to that, 

[david]

I'm using Virgin Business Broadband (VOOM 350), I have tested with the virgin broadband router in both modem and router mode with the same result. So I've tested with a router in front of the R1. I'm not using IPv6 or PPPoE - these are disabled on the R1. Test results are as follows. Results obviously vary with repeated tests but they are usually around these figures.

 

Down/Up Cap   Ping   Down Mbps    Up Mbps

100%          12     386          18

99%           12     133          15

50%           12     120          12

Im wondering why putting it behind another router would make a difference ? 

What I was thinking was that perhaps the R1 hardware could not handle accurate CC filtering at speeds above 250Mbs , and adding another 

router in front would offset some of the processing load off the R1 to the first router , and CC would accurately filter my speeds. 

 

Id like to get instructions from a netduma tech or guide to ensure that its setup properly. 

[Netduma Fraser]

All you need to do is do modem > router > R1, no need to change any settings on the router before the R1 and test using the same settings on the R1. I assume with super turbo mode that you also get your full speeds

[SleepyWeasel]

Was there a resolution to this. I also now have 250 down and 25 UP and at 100% I get about 300 down, but at 70-99 I get about 160 download.
