How to Set Upload and Download Speed on Qos
Let me guess. You're here because you've had an consequence with Voice over IP (VoIP) or video conference calls. Or perchance y'all've had some general issues with your Net speed. You lot're not alone!
This post will assist you configure your existing router to get the best possible feel in real-fourth dimension online communication, or Netflix streaming, or any other things you do online, for that matter.
It's all most QoS.
Dong'south note: I first published this post on March 23, 2020, and updated it on December xvi, 2021, with additional relevant data.
QoS explained: What is it?
QoS stands for Quality of Service — a routing characteristic that allows users to prioritize the bandwidth — most applicative to the Internet bandwidth — for specific programs, clients, or services.
In a nutshell, the way it works, QoS takes the existing broadband connection and designates a specific amount of requested bandwidth to your desired target, in existent-time, before the rest of the network.
For example, if yous prioritize VoIP, your Internet-based calls will get all the bandwidth it needs before any other applications. Or, if you lot prioritize your Xbox (or a particular game), then the game console will get the first dibs on the Internet earlier whatsoever other devices.
And you can do that with anything you desire, like Netflix streaming or online surfing. You can even exercise that with file downloading, besides — though, well, you shouldn't.
Downloading never requires prioritizing. Instead, it's the reason why you need QoS in the first identify. When left lone, a single file download task will hog all the bandwidth, no matter how fast the Cyberspace connexion is, until it'southward complete.
So, QoS is sometimes also nearly giving specific devices or services the lowest priority of the broadband to make sure they volition not interfere with the regular operation of the balance of the network.
When properly configured — non an piece of cake task — QoS can make everyone happy, even when you have a small-scale Internet connexion.
What QoS vs Net speed
It's of import to note that QoS is not nearly making your Internet speed fast(er) — you wish! It's almost giving y'all exactly what you (your device at hand) need when you need it and possibly not more than.
Consequently, when you plough on QoS, y'all tend to have slower speed test results — and that's the betoken because speed testing is not how we generally use the Internet. Keep that in mind.
Too, when you misconfigure QoS and set its download speed significantly lower than your broadband'south actual speed, then the fix QoS speed will exist the ceiling for the entire network.
That said, if y'all have turned QoS on in your router and now upgrade your Intenet to a faster speed grade, make sure you adjust your QoS settings. Else, y'all'll continue to get the quondam speed.
It'south about agreement how it works and paying attention.
What you need to utilize QoS
You mostly need two things to take reward of QoS.
First and foremost is a router that supports this characteristic. Most, if not all, home Wi-Fi routers accept QoS, but the fashion they do it varies from i vendor to some other. At that place are a lot of degrees and nuances when it comes to this feature.
In my experience, Asus routers support this feature well and allow for easy configuration. Those from Linksys, Netgear, and TP-Link are besides quite good.
Secondly, y'all need to know your Internet connection's actual speed and quality. It'south pretty easy to find out — I wrote a long piece on speed testing if yous need to know the exact numbers and what they mean.
Just more often than not, you can do a quick speed test right now to find out your ballpark figures.

Done? I hope you got good numbers.
Hint
Information technology's best to know your exact broadband speeds when setting up QoS, which can exist a tricky thing.
That said, keep in listen that it'due south OK to employ a slightly lower speed for your QoS. So if you have 500Mbps for download, you can enter 450Mbps.
Even so, it'southward never practiced to utilize a higher number. (Like 550Mbps). In this case, QoS might produce no meaningful outcome at all. Information technology can fifty-fifty brand things worse.
The rule is this: Set your QoS to use as close to the exact broadband bandwidth as possible, but never above that.
With that, let's fix the right expectations on what you can get out of your QoS-enabled Internet.
Setting the right expectations with QoS
For QoS to be effective, your Cyberspace has to be at least fast enough, or amend yet, faster than what's needed by the prioritized political party. So, say, if your application needs 25Mbps of download speed and your broadband caps at 20Mbps, well, no QoS tin help y'all in this case.
I picked 25Mbps for a reason. That's the download speed required for streaming 4K content on one device, from Netflix or any other service.
So if you're suffering from buffering and expect fourth dimension while streaming over a modest Internet connection, don't immediately arraign your Wi-Fi for it — they are 2 different things.
As well, QoS tin not meliorate the quality of your Internet connection. For example, if your broadband has high latency (lag), which is terrible for real-time communication, QoS won't amend that. All it can do is give a particular awarding, service, or customer within your network the best possible experience within what you have.
Lastly, QoS is more often than not non necessary when yous have a high-speed broadband connection that has enough bandwidth for all of your applications at once.
But even then, if you lot know that somebody in your abode regularly downloads stuff, like using a BitTorrent client, then it's still a good idea to turn this characteristic on.
That is a typical case where depression-priority QoS applies, as mentioned above.
Broadband requirements for VoiP and video conferencing
Generally, a broadband connection of 50Mbps download / 15Mbps upload or faster is plenty for almost any online application. That'due south one case of the app.
If yous have multiple applications, keep in mind that each requires similar bandwidth of its own. For example, most video conferencing apps crave at least 2Mbps per screen.
In reality, information technology likely uses more than if yous do that in Total HD or 4K. And then, to be sure, give each screen an resource allotment of 25Mbps for download.
The upload pipe varies. Just if yous want folk on the other end to see you in Hard disk, you lot'll need 25Mbps for upload, too. Unfortunately, most cable broadband can't deliver that since they cap at effectually 15Mbps. So likely, you can only broadcast yourself at lower resolutions.
Net-based vocalization/video communication'south requirement on latency is relatively lenient. Specifically, your connexion should have less than 150ms (millisecond) and 30 ms in Ping and Jitter values, respectively, for VoIP to work well. (Ideally, you desire those numbers to be 15ms and 10ms, respectively.)
A typical residential broadband connectedness generally has those at less than 20ms. Only the lower the values, the better the call quality you'll get. That is, of form, assuming that you don't plow on the (out-going) video quality to require more than that of the upload pipe.
It's important to notation that yous should remain relatively at ane spot (or one room) while doing a voice or video telephone call — improve yet, start your Wi-Fi connection at that location. If y'all have the habit of moving around your (large) house, no router or organization tin make that work well. So no QoS can help, either.
(Past the way, the quality of a real-time communication application depends on both ends. The point is don't immediately blame your Internet for a sub-par experience — information technology might be the fault of the remote party.)
How to configure your router's QoS
The style you work with QoS varies depending on the routers. Generally, routers from the aforementioned vendor share the aforementioned interface or mobile app, and therefore the same mode for users to customize their settings.
The web interface is e'er the best way to manage a router since information technology gives y'all in-depth access to all features and settings. And QoS is ane of those advanced features. But some vendors, like Linksys, likewise allow configuring this feature via the mobile app.
Just I always prefer the web interface, and here are the general steps on how to configure your QoS:
ane. Log into your router's interface
To do this, navigate your browser (Chrome, Firefox, or Edge) to the router's default IP address (or friendly URL).
If you don't know yours, check the table below or this mail on IP addresses. And log in with your router's admin business relationship.
| Vendor | Friendly URL | Default IP | Username | Password |
| Asus | router.asus.com | 192.168.i.1 192.168.fifty.1 | admin | admin |
| AT&T Gateway | n/a | 192.168.ane.254 | due north/a | Access code printed on the hardware unit |
| Comcast (Xfinity) Gateway | n/a | 10.0.0.i 10.1.10.i | admin cusadmin | password highspeed Access code printed on the hardware unit |
| D-Link | dlinkrouter.local | 192.168.0.1 192.168.1.1 | n/a | admin |
| Netgear | routerlogin.com | 192.168.1.1 | admin | password |
| Linksys | myrouter.local | 192.168.0.1 192.168.1.1 | n/a | admin |
| TP-Link | tplinkwifi.net | 192.168.0.1 | admin | admin |
| Most Cable Modems | Due north/A | 192.168.100.1 | n/a | admin password default |
2. Customize the router'southward QoS characteristic (for VoIP)
This feature is virtually always in the Advanced area of the interface. It more often than not has "QoS" or "Prioritization" in its name.
Traditionally, you'll need to enter your broadband connection's download and upload speeds. In this case, enter the verbal numbers or slightly lower ones.
Again, definitely don't enter higher numbers than your actual download and upload speeds. Some routers tin can effigy out these numbers by themselves.
Now, brand sure you lot prioritize the QoS according to your needs. For this commodity, pick VoIP and video calls as your top priorities.
If there's no option to prioritize a service or application, you tin cull to prioritize the particular client on which yous'll apply the service. So if you use your iPad for conference calls, make your iPad the 1 with the highest priority.
Note that if you choose to prioritize a particular device, it's a good idea to take that device's IP accost reserved within the router so that it will not change.
Here'south how you can reserve a local IP address, and here's everything you need to know near the MAC address. Yous need to understand both to make things work properly.
This setting applies when y'all demand your router to work well for Vocalism over IP, and fifty-fifty and then, only to specific situations. And so it's something to attempt when you accept Wi-Fi calling issues, like delays.
SIP ALG stands for Awarding Layer Gateway, a setting available in most home routers and is turned on by default. Initially, this setting intends to assist improve VoIP packages travel through the router'southward firewall. In reality, it rarely works out as expected and often causes issues.
So, y'all might need to turn SIP ALG (also known as SIP Passthrough or SIP) off (or disabled ) to have a better VoIP experience. The location of the SIP setting varies, merely generally, yous tin can detect it in the WAN (Cyberspace) or Firewall surface area of a router'southward interface.
3. Apply the changes
In one case you've changed the setting, make sure you utilize it. In some instances, the router might restart. Fifty-fifty if yours doesn't, it'south a proficient thought to manually repower it, then bank check again to ensure the new settings are correctly set up. Now, your QoS is in effect.
Extra: Steps to optimize Asus's QoS for voice and video communications
If you lot happen to take an Asus router, the post-obit are specific steps to customize its QoS for vocalism and video conferencing. While they are not the same as how you lot'll discover in a router from another vendor, they will give yous some ideas.
Update: In tardily March 2020, Asus released a firmware update — for most, if not all, of its routers — that adds boosted categories to the Adaptive QoS feature. I of these is Video Conferencing (or Work-From-Dwelling), which prioritizes the Net for real-time video communication apps, including Microsoft Teams, ZOOM, Skype, Google Hangouts, and BlueJeans.
1. Log in to your router'southward web interface.
From a connected estimator, signal your browser to router.asus.com, you'll reach the interface. Enter your username and password and click on Sign In.
two. Update to the router to the latest firmware
- Click on Assistants menu item
- Click on Firmware Upgrade tab
- Click on the Bank check push for new Firmware Verison. Alternatively, you can also download the firmware directly from Asus. In this case, use the Upload push button to upload the firmware to the router manually.
- Follow the balance of the process to upgrade the router to the latest firmware. Note: Don't turn the router off during the process which will accept no longer than 5 minutes. Afterwards, it'southward a good idea to manually restart the router.
iii. Turn on the AdaptiveQoS features
- Click on the Adaptive QoS menu item and then on the QoS tab.
- Slide the Enable QoS to On
- Click on the Video Conferencing button. Note: In certain router models, existent-time advice as part of the Work-From-Home category.
- Optional: Click on Customize and elevate the blocks of other categories according to your needs –you can hover the mouse on each block to see what blazon of applications/services that category includes. Then click on Save.
- Click on Apply.
The router will take a few seconds to utilize the changes.
four. Disable SIP Passthrough (when need be)
- Click on the WAN menu (under Advanced Settings), and then on the NAT Passthrough tab
- Change the value of SIP Passthrough to Disable
- Click on Apply, and wait for the router to apply changes.
Manually restart the router and check to brand certain all is good. And that's it! Your Asus router should work amend for your online communication application now.
Last thoughts
Internet traffic is somewhat like cash menstruum for a household (or a concern) — information technology'south all nigh managing its correct and staying on the upkeep. And that's where QoS comes into play.
Once more, this feature is about giving a device the bandwidth information technology needs (and no more than) when information technology needs it. It does not make your Internet faster.
QoS is about degrees and nuances. When yous configure it correctly, you'll exist surprised how lilliputian Internet bandwidth you actually need.
And vice versa, in a poorly configured network, even Gigabit broadband is not consistently fast enough for every device within the network.
