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 to your network over WiFi or using an Ethernet cable connected to your modem. This works best on a tablet or computer.
2. Open a web browser and type http://192.168.0.1 into the web address field.
3. Sign in to the modem settings (GUI) using your Admin Username and Admin Password, printed on the sticker.
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 your modem sticker. It includes your default Admin Username and Admin Password, which cannot be retrieved if lost. Your modem could become unusable without them.
4. Select Advanced Setup 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.
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.
If you have a 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.
