Use Dynamic QoS to Optimize Internet Traffic Management
Dynamic Quality of Service (QoS) helps improve your router’s Internet traffic management capabilities through better
application and device identification, bandwidth allocation, and traffic prioritization techniques. Dynamic QoS resolves
traffic congestion when the Internet bandwidth is limited and different demands compete for bandwidth.
If your Internet download and upload speed is 250 Mbps or less and you like gaming and streaming video, then you
can benefit from enabling Dynamic QoS.
If you use a Gigabit Internet connection, or your Internet download and upload speed is 300
Mbps or faster, then you don’t need to use Dynamic QoS.
Note
Figure 9. Dynamic QoS optimizes Internet traffic by prioritizing competing demands
Enable Dynamic QoS
Because not everyone uses Dynamic QoS, it is disabled by default.
To enable Dynamic QoS:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the modem router user name and password.
The user name is
admin
.The default password is
password
.The user name and password are case-sensitive.
