QoS on Synology Routers: Practical Guide
How to Improve Quality of Service (QoS) on Synology Routers
Network congestion is a daily problem now that remote work, video conferencing, cloud backups, and streaming are all fighting for bandwidth. Increasing the speed of the internet doesn’t always fix performance problems. Smart traffic management is often the last piece that is needed.
Quality of Service (QoS) on Synology routers with SRM helps keep important applications stable even when there is a lot of traffic. When set up correctly, QoS turns your router from a simple gateway into a smart traffic controller.
Why QoS Will Be More Important in the Future
Networks today can handle a lot more traffic at the same time than they could a few years ago. Some common activities that use a lot of bandwidth are:
- Backups and file sync in the cloud
- Streaming video in 4K
- Platforms for video conferencing
- Big updates for software
- VPN connections from afar
A single large download can stop video calls or remote work sessions if you don’t set priorities.
QoS makes sure that traffic that is important to the business gets priority over activities that aren’t.
How Synology QoS Works
The RT2600ac and MR2200ac are examples of Synology routers that use SRM’s Traffic Control feature to manage bandwidth.
QoS lets you:
- Set limits on the amount of bandwidth you can use
- Put devices in order
- Put applications in order of importance
- Make sure there is a minimum amount of bandwidth
- Limit how guests can use the network
SRM looks at traffic patterns and uses shaping rules to keep key services from getting too busy.
Step 1: Find out how fast your internet really is
Find out your real upload and download speeds before turning on QoS. Use a speed test that you can trust and keep track of the results.
When setting up QoS in SRM:
- Enter values that are a little lower than the highest you measured.
- This lets the router manage traffic well.
- Traffic shaping becomes less accurate if you set speeds too high.
Step 2: Put the most important business apps at the top of the list
In the office or when working from home, make sure to:
- Traffic on a VPN
- Platforms for video calls
- VoIP services
- Tools for working together in the cloud
In SRM, prioritizing applications is better than just prioritizing whole devices.
Step 3: Control the bandwidth on the guest network
Guest networks are often the cause of traffic jams. Downloading or streaming a lot of data on guest Wi-Fi can slow down the network for internal users.
Use QoS to:
- Set limits on how much bandwidth guest networks can use
- Stop guest traffic from using too much upload bandwidth
- Keep the quality of service high for internal systems
This is very helpful in small offices and places where people work together.
Step 4: Be careful when balancing upload bandwidth
The upload bandwidth is often the problem. Uploading large files, backing up files to the cloud, and streaming security cameras can all use up all of your upload space.
If the upload bandwidth is used up:
- Video calls stop working
- VPN sessions end
- Remote desktop stops working properly
Set upload prioritization for services that are important to the business first.
Step 5: Keep an eye on traffic all the time
SRM has dashboards for monitoring traffic that show:
- Bandwidth use in real time
- Consumption per device
- Traffic at the application level
You can’t just set up QoS once. It should be able to change with the network.
Benefits of SRM for Synology Users
Synology SRM combines QoS with:
- Rules for the firewall
- Integration of VPN servers
- Preventing threats
- Filtering DNS
This unified approach makes it easier to manage a network than having to deal with separate devices for routing and monitoring.
The desktop-style interface of SRM also gives you more control than many consumer routers that use mobile apps.
About Epis Technology
About Using Synology routers, Epis Technology helps businesses set up structured network environments. The team looks at how much bandwidth is being used, sets up QoS policies that work with remote work and cloud backup needs, and combines router security with firewall, VPN, and hybrid backup plans. Companies can avoid congestion while keeping security and performance stable by making sure that QoS is in line with their overall infrastructure planning.
