Netduma r3 jitter sorunu

[kaan006]

I use a Netduma R3 and my jitter is very high during online Warzone matches. When I disable the bypass mode, the jitter drops, but that doesn't give the true jitter value. Since my router is connected to the main modem, could my high jitter be caused by a double NAT issue? If I enable Bridge mode or DMZ, will my jitter value drop? My jitter is around 15 ms, and I want to reduce it down to about 2 ms. I am experiencing a lot of lag—will DMZ or Bridge mode solve this issue? I'm looking for information.

Disable what bypass mode exactly? Well you should definitely put the R3 in the modem DMZ or put the modem in modem mode, it will likely help but:

• Are ALL devices connected to the R3?
• What are the speeds you pay for/receive?
• Have you entered those speeds into the router?
• How have you setup Congestion Control?
• How have you setup SmartBOOST?
• What platform are you playing on and how is it connected, via ethernet or WiFi?
• How have you setup the Geo-Filter?

Depending on the inherent stability of your connection it may not be possible to get to 2ms jitter.

None of the other devices in the house are connected to the router; only the PS5 is connected because I only game on it. I have a 1000/50 Mbps internet connection, but when I run a speed test on the PS5, it shows 45/9 Mbps. I am testing from Turkey, and the closest server is Frankfurt. I logged into the router, enabled Smart Boost with Warzone prioritized, and set up traffic control for the PS5, allocating 80/70 Mbps, which changes the values slightly. I am playing via a wired connection, but since the geo-filter is set to Europe and the jitter doesn't drop, opponents always appear ahead of me, which I can see very clearly. Would using bridge mode or DMZ improve this? I would appreciate your help.

You should definitely put the R3 in the modem DMZ or put the modem in modem mode, it will likely help but:

• Are other devices connected to your modem then?
• Have you entered 1000/50 into into the router?
• How have you setup Congestion Control? I can't see from your screenshot how it has been set.
• You mean you reserved bandwidth for the PS5? You don't need to do that, gaming barely uses any speed and it won't use that.
• What is your ping as shown on the Geo-Filter?

I set up DMZ, but I am the only one connected to the router; the other users are connected to the main ISP modem. My ISP speed is 1000/50, but the test shows 50/44, and traffic congestion is 80/70. In Geo-Filter, my ping fluctuates between 52 and 65. When Speed Test Bypass is enabled, my jitter is high (around 15); when disabled, jitter drops to 3. However, if Speed Test Bypass is disabled and the jitter drops, it doesn't seem to help. How can I lower the jitter while Speed Test Bypass is enabled during online games? Do I need to configure a setting on the main modem? Because of the jitter, I constantly experience delay. I never experience stuttering, but I can visually see that the opponent reacts before me. I want you to help me.

When the Speed Test Bypass setting is enabled, no matter what I adjust in the Congestion Control, it doesn't work and doesn't lower my values; if I turn it off, I get an A+, but if it's on, I get a B.

[Netduma Fraser]

ALL devices need to connect to the R3 otherwise the R3 can't effectively control your network, this will be a big reason for your issues. You also need to enter the speeds you pay for in Speed Test > Advanced. Once you do those things you should notice a difference and that Congestion Control does a better job at reducing jitter/bufferbloat.

[kaan006]

I connected all devices to the Netduma, entered the speed settings I receive, and my DMZ setting is also done, but my jitter went up to the 30s when it was between 12 and 16, it's not working at all.

[Netduma Fraser]

You'll need to fine tune Congestion Control to find what percentages work best for you and I can still see that you've not set the speeds you pay for into the router i.e. 1000/50.

I am entering through the server ID code written here, but when another game starts, it says 'This server is mostly stable, but your gaming device is no longer connected to it,' yet when the game starts, my ping values are the same and I play stably. Am I being put into the server ID written as QJXRAX or other server IDs? I don't understand this section. There are other countries on the custom map as well, but I marked the lobby I liked, it turned green, and it started to become very stable. Previously it was Frankfurt, but the server code kept changing. Could you help me? Is it constantly putting me into the game with the same code, and why does it find it immediately, whereas this had never happened before?

[Netduma Fraser]

Whatever the server code it is showing you is the one you're in - unless you're pinging it manually instead, if you're letting it automatically ping then it will be the one it shows

[kaan006]

Does pinging it manually keep us constantly on that server, or does staying on automatic keep us locked to that server? I clicked on the console icon, and a green message appeared saying, 'You have allowed this server, which means we can always connect to it.' But when I enter the server, it says, 'This server is quite stable, but your gaming device is no longer connected to it.' For example, how can we make it constantly join a specific server? If I like a server, I want to keep joining the same one consistently, as some servers can be quite challenging.

[Netduma Fraser]

No it's just to do with pinging, it doesn't continually force you on that server. That means you always have the potential to connect to it i.e. that your Geo-Filter settings will never block the connection even if they would do ordinarily but it doesn't guarantee a connection to the server. You can't force a specific ID server over and over but you can force the same location. 

To force servers you need to do the following:

It's essential the Geo-Filter is enabled before the game client (e.g. Steam etc) if on PC or platform (e.g. Xbox, PlayStation) or the game have been launched. If you change Geo-Filter settings when you're on the game then you will need to restart the game for those changes to take effect, otherwise it will use the previous Geo-Filter settings and appear not to be working.

For settings ensure Ping Assist and Geo-Latency are disabled in the Geo-Filter menu that can be found by clicking ⋮ in the top right hand corner of the page and go to Settings.

Strict Mode should also be enabled, it is enabled by default so if you haven't disabled it you can ignore it. If you have disabled it or want to check it can be found in the same Settings menu as above or in Settings > Troubleshooting > Advanced > Developer Options depending on your firmware version. Fast Search should also be disabled which it is by default so can be ignored if you haven't changed it, otherwise this can be found in the same place.

Behaviour I noticed from warzone on ps5 and Xbox. When you get that alert noise and it’s searching for 115 more players/match start in 5 seconds’ etc so basically the lobby you’re connecting to one server. When you enter the match, you are on a different server. So there’s a divide between match and lobby server although if the lobby server is in Frankfurt the match server will be as well. I would only look at Geo filter once match has started, so when it shows you on plane.

Not sure if you’re aware in season 3 (April if my memory recall is well) there were performance issues on ps5. Symptoms were visual lag (like someone smeared cement on your screen), sluggish movement like you are running through cement, hitching, plus game speeding up and slowing down. They did fix it the following season but sometimes it can show up. 

For PS5 I fully recommend going into graphic settings and turning texture streaming to minimal as optimised texture streaming from my own testing makes the performance issues reappear.

Size gösterilen sunucu kodu neyse, o sunucuda bulunuyorsunuz demektir - manuel olarak ping atmıyorsanız. Eğer otomatik ping atmasına izin veriyorsanız, gösterilen sunucu o olacaktır.

Isn't it better when I manually find a stable server and enter it myself? Even with 99% stability, it puts me in sweaty lobbies, and it has nothing to do with SBBM (SBMM).
