How to configure Quality of Service (QoS) on your modem
Quality of Service (QoS) allows you to prioritize certain devices or certain types of internet traffic (such as VoIP or video). This can improve performance for certain applications when bandwidth is tight, and prevent your network from becoming overloaded.
1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.
2. Open a web browser and type http://192.168.0.1 into the web address field.
3. Log in to the modem's settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security key).
You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.
CAUTION! Do not remove or lose your modem sticker, which includes your default admin username and password. These preset credentials cannot be retrieved, and your modem could become unusable without them.
The modem sticker shows you TWO important sets of login credentials. How do you use each one?
SSID and key/wireless password: Used to access and connect to your WiFi network
- SSID is the name that will show up on your devices in the list of wireless networks (may have two for dual-band modem/routers)
- Key/Wireless Password is the password you will enter on your devices to connect securely to your network
- These default settings can also be customized in the modem settings or through the app
Admin username and admin password: Used to log in to your modem settings portal
- Access secure settings such as firmware updates, WiFi security, schedules, and more
- When connected to your home network, go to http://192.168.0.1 to access the portal (also called the GUI)
- These default settings can also be customized in the modem settings
4. Select the Advanced Setup icon in the main menu.
5. Select "QoS" in the left sidebar.
6. Follow the steps to edit the QoS settings. Depending on your modem, you may see slight differences in how the options appear. Users of the C4000 series modems, follow the instructions at the bottom of this page.
- Step 1: Enable QoS.
- Step 2: Set the QoS traffic direction to upstream or downstream (or both, in newer models).
- Step 3: Select the QoS type, or "Create Custom QoS" to define your own priority rule by IP address (recommended for advanced users only). You can create multiple rules for different QoS types and/or devices. You can also remove previously created rules from the QoS Rule List at the bottom of the screen.
- Step 4: When you're finished adding or removing items, click "Apply" to save your changes.
6. If you have a Greenwave or a Zyxel C4000 series modem, QoS will be enabled automatically when you create and apply at least one priority rule. To set QoS, follow the steps below.
- Step 1: Choose or manually enter the IP address of the device you want to manage.
- Step 2: Select the traffic direction you want to control (upstream, downstream, or both.
- Step 3: Select high, medium or low priority. This will determine whether the chosen device is prioritized when bandwidth is limited.
- Step 4: You can also remove previously created rules from the QoS Rule List at the bottom of the screen. When you're finished adding or removing items, click "Apply" to save your changes.
