Unfinished Posted November 23, 2020 Share Posted November 23, 2020 I have been running benchmark test for the last two days and had what I thought was a good ping under load, with all three figures being around 20ms. Download speed was stable at around 17mbps and upload just above 2mbps (yes, laughable really, but that's the best I can get), and the results were consistent. QoS download slider at 30%, upload at 20%. Last night at around midnight, I thought I'd test again, with everyone now in bed and off the network I thought I'd get better results, but things went the other way, with erratic ping, spikes and an odd ping graph best described as a saw tooth with a rising trend. I checked again this morning and have much the same. What would cause this change? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted November 23, 2020 Administrators Share Posted November 23, 2020 It is odd it would suddenly change like that. It is possible that it's because the upload percentage is too low for it at that time, if you raise that does the ping decrease? Link to comment Share on other sites More sharing options...
Unfinished Posted November 23, 2020 Author Share Posted November 23, 2020 No significant change. It's odd because yesterday, early evening my ping results were in the low 20s across the board. It could be the phantom line fault, but no-one seems to be able to track it down. Would a different DNS server make any difference? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted November 23, 2020 Administrators Share Posted November 23, 2020 I wouldn't have thought so no, we do use the Google server though so put 8.8.8.8 in for DNS and see if that affects it. Link to comment Share on other sites More sharing options...
Unfinished Posted November 23, 2020 Author Share Posted November 23, 2020 ...and for no apparent reason, with no changes made, I have just got this. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted November 23, 2020 Administrators Share Posted November 23, 2020 It must have been that the Google server itself was under load at the time, most likely if you did a different test to another server it would have been fine.

Unfinished Posted November 23, 2020 Author Share Posted November 23, 2020 I was on Cloudflare at the time and those reading were going on for more than an hour last night and the same again this morning. If it happens again, I'll try swapping to the Google DNS instead. Netduma Fraser 1 Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 I've looked at this a bit closer and have monitored the ping testing over a couple of hours last night. Some of the following behaviour must be down to the QoS features. At some point whilst the XBOX was on, the R2 stopped all internet traffic to and from every other device in the house. The XBOX continued to work, I could access the R2 web interface and run tests, but nothing else. Ping testing during this time gave fairly consistent results of 24ms or so. When the XBOX was shutdown the ping jumped up considerably and remained so, but the XBOX wouldn't reconnect to the network. I rebooted the R2 to get the network back up and tested the ping under load again, same results, XBOX on - low ping, XBOX off - high ping. A swap to the Google DNS didn't make any difference for what it's worth, but was just something to try. I know very little about networking, but thought this might be of use.

Administrators Netduma Fraser Posted November 24, 2020 Administrators Share Posted November 24, 2020 That is very very strange, it's more likely to be better if a device is off than on so it's backwards. When the xbox is off is it in rest/standby mode or is it completely shutdown? Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 Completely off and I agree, it seems like a reverse situation. Link to comment Share on other sites More sharing options...

Administrators Netduma Fraser Posted November 24, 2020 Administrators Share Posted November 24, 2020 That is so peculiar. Could you do a test please so we can see if it's reporting correctly or not? Follow this guide while saturating your network with downloads streams etc using your Congestion Control settings, use 8.8.8.8 as the target address. Do one with the Xbox on and one with the Xbox off please. I suspect the results will mimic the bottom picture in both tests. Then we can be sure it is a weird bug we need to look into. http://support.netduma.com/en/support/solutions/articles/16000074717-how-to-test-your-internet-ping Link to comment Share on other sites More sharing options...

Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 It does look like the ping figures are slightly higher without the XBOX switched on. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted November 24, 2020 Administrators Share Posted November 24, 2020 Brilliant, that is great, thanks for doing that. At what Congestion Control percentage was that on? When the Xbox is on you're actually getting some packet loss there so that's not good at all. Definitely something weird going on. When the Xbox is on, could you have a look in the Network Monitor please and see if it's using any significant traffic? Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 30% down and 20% up. These gave me the best figures, but the auto setup gave me 1%, which was unworkable. Network monitor shows some use over the two xboxes, but other devices have disconnected, as is often the case when the xboxes are on. I have always seen packet loss when playing Apex Legends, but that might not be indicative of a network problem. There are a few possibilities. I have Cat 5e cables, which should be sufficient for my lack lustre connection speed, but I have a pair of new Cat 6's coming this week to swap out the older cables. Bit by bit, I'm eliminating possible problems, but I'd say the R2 isn't entirely responsible for the packet loss. Who knows? In a short while I'll be stopping for some food, so I'll run another check with the Xboxes off. Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 Some pretty heavy packet loss, but I'll need to test the other Xbox separately when the network is quiet again later. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted November 24, 2020 Administrators Share Posted November 24, 2020 I realize it's frustrating but would you be able to do some more tests please? Same as above but adjusting the Congestion Control sliders as it's pinging and you're saturating the network - one with XB off, one on If possible same 4 tests but direct to ISP modem Also just in case, make sure you're doing these all wired please. We are definitely getting there! Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 To clarify my network setup. BT OpenReach Modem (HG612 3B) > Netduma R2 > LAN 3 > Ethernet Switch > Xbox One LAN 4 > Xbox One X Link to comment Share on other sites More sharing options...

We are definitely getting there! What do you mean by this? Do you mean ping the modem and not 8.8.8.8.? Also, The Xboxes are wired, I'm not sure what could be wireless in this test, so presume it's all wired. As for the frustration, well it is a bit, but first world problems really.

Administrators Netduma Fraser Posted November 24, 2020 Administrators Share Posted November 24, 2020 Sorry I'll clarify. When I say direct to the modem I meant have the PC and console connected to the modem instead of the R2 but I can see that isn't possible now. Just making sure the PC doing the testing is also wired. The switch is it managed or unmanaged? Link to comment Share on other sites More sharing options...
Unfinished Posted November 24, 2020 Author Share Posted November 24, 2020 Ping test with network under load and to 8.8.8.8. XBOXes On. Both sliders moved to 60%. Link to comment Share on other sites More sharing options...

The switch is it managed or unmanaged? My Mac doesn't have a LAN port, so no dice there. The switch is an unmanaged one. Netgear GS305. Presumably you want to cut out the R2 and check downstream?
