15 Ways to Improve Slow Comcast Xfinity Internet Speed

Have a glance at these little efforts to restore and refresh your Xfinity internet.

1. Check Your Xfinity Internet Speed
  • Check the number of devices and people connected to the network before conducting the speed test.
  • Perform the speed test using online tools like Ookla, uptrends, GTmetrix, etc. Then compare the results to your current internet package.
  • If the result matches your plan, then your only option is to upgrade your internet subscription for increasing the speed. 

[Note: For upgrading, you can check your “My Account” page in the Xfinity app to get more details on speed tiers and internet plans.]

2. Restart Your Equipment 
  • Restart/reboot is the first thing that comes to our mind when we encounter internet issues. This process clears all the faults and storage as well as improves the performance of your router and modem. 
  • You can quickly restart them either from the app (or) directly by pressing the “Restart” button located on the device.
  • Additionally, it is also suggested to restart the connected devices with the network. 
[Note: It is recommended to restart all the devices at least once in every month as a part of regular network maintenance.]
3. Check Your Connections
  • Ensure that your modem/router is securely connected to the power source.
  • If you are using an Ethernet cable instead of WiFi make sure that these wires are not broken (or) cut off to establish a stable connection.
  • And connect high-bandwidth devices like computers, gaming consoles, smart TVs, etc with an Ethernet cable to prevent constant buffering. 
4. Place Your Router in the Center
  • When it comes to router placement, we always dangle it at one corner of the house resulting in slow internet.
  • That’s why, move your router to a central location in your home to improve connectivity and signal strength.
5. Secure Your Network
  • Nowadays, one of the most pressing issues is security. So, always set strong and unique passwords to secure your network and critical data from malicious activities, unauthorized access, and cyber assaults. 
6. Update Your Router’s Firmware
  • Firmware upgrades are usually handled by Xfinity for you. If you do not have an Xfinity xFi Gateway, you must frequently upgrade the firmware of your router/modem. 
  • Updating the firmware on the router can improve network connection and performance. 
  • You can effortlessly update the firmware by downloading them from the app.

[Note: Along with the router update your system drivers also.]

7. Fix Your Device Issues
  • If you are having sluggish internet, always the problem may not with the internet but with your equipment.
  • Simply disconnect and reconnect the device to the network (or) try connecting the device to another network (or) restart the device and troubleshoot it.
8. Check Your Xfinity App
  • Visit the Xfinity app when the internet is very slow. Because usually, Xfinity posts all the alerts (or) messages in the app when there is a network outage. 
  • Wait for a while, if you don’t find any alert in the app. If the problem persists proceed further with the other options.
9. Minimize Interference
  • Avoid putting the router in a confined space (or) near thick surfaces, such as concrete walls.
  • Moreover, place the router away from electronic households like ovens, Bluetooth-connected devices, refrigerators, baby monitors, etc which can interfere with the signal. 
10. Implement a Mesh Network, WiFi Repeaters (or) Extenders
  • If you have a large house with poor Wi-Fi coverage, consider installing Wi-Fi repeaters, extenders (or) a mesh network system.
  • These gadgets fix a shaky connection and provide a full-coverage WiFi network across your house.
11. Upgrade Your Router 
  • Outdated routers can make internet use more difficult, leading things to operate infrequently (or) not at all. That’s why it is vital to update your router with new software versions. 
  • The routers with updated technology allow them to function better with today’s infrastructure. They have greater range and data speed, so an upgrade could be beneficial.
12. Upgrade Your Modem 
  • Connect your device directly to the modem using an Ethernet cable to test your modem. Perform an internet speed test and compare the results. 
  • However, if the test results in a lesser download speed then you must buy a new modem. 
13. Enable Quality of Service
  • Enable the QoS feature in your router’s settings. By activating these options on your router, you can prioritize specific programs (or) devices, resulting in a more seamless online experience.
14. Connect to the Right WiFi Network
  • In some cases, you may accidentally select the wrong network (or) your device may connect to the other network automatically. 
  • That’s why always double-check that you are connected to the right Wi-Fi network. If you connect to the wrong network, disconnect and find your own Wi-Fi network to join. 
15. Contact Comcast Xfinity Support
  • If the above steps don’t work (or) improve your internet speed, reach out to Comcast Xfinity’s customer support immediately.
  • They can give more support, remotely troubleshoot your connection (or) schedule a service visit if necessary.
