Restoring your internet speed is not that complex. You can try the fixes listed below, and you might fix the issue yourself!
Being an Xfinity user since 2017, I know how to fix most of their issues. I went for Xfinity because of their flexible plans ranging from 25 Mbps connection to 1 Gbps connection.
However, I just discovered that I was not receiving the speed I had paid for while downloading something from the internet.
Though the speed was enough to download Gigabits of data in minutes, it is still frustrating.
So, the first thing I did was to call their helpline, and they took me down by saying network congestion (Which is understandable, as I am their shared network user.)
Now, Xfinity support is not helping, and I have to fix it myself, and so do you.
Here come hours of research and suffering to fix Xfinity Not Getting Full Speed issue.
Symptoms of Slow Xfinity Speed
There are several possible reasons your Xfinity connection is not getting full speed:
- Network Congestion: Network congestion occurs when traffic overloads the network. Typically, this issue slows down the network for the end users. (In many cases, latency, throughput, and bandwidth are connected to congestion.)
- Network Outage: A network outage is any unplanned time when the service is interrupted and unavailable for at least a 1-minute within a period of 15 minutes.
- WiFi Congestion: WiFi congestion occurs when there are too many devices connected to your home wireless connection.
So, from the symptoms, it is easy to guess that the issue can be from the Xfinity side, or it can be from your side too.
The solutions are simple and easy, but they might require effort from your side.
Xfinity Internet not getting Full Speed: The Root Cause
First and foremost, you must find the root cause of your low-speed internet. Is the issue from the Xfinity network congestion, or is it because of your home network connection?
If the Xfinity network is causing low speeds:
- Your internet speed is less than the speed that your plan guarantees. To find out the maximum speed you can get with your home network, check your Xfinity bill, or you can also check on Xfinity App.
- Your internet speed only falls at the peak time (After 6 PM, mainly because users are active after working hours.)
- You are not getting full speed even if the WiFi signal strength is maximum.
- Your internet speed is slow on all of the connected devices.
If your home network is causing low speeds:
- If you are getting slow internet on a particular device and other devices are getting full speed.
- If you are the only one getting low speed in your neighborhood.
How to Fix Slow Internet speed on your Xfinity connection?
Restoring your internet speed is not that complex.
You can try the fixes listed below, and you might fix the issue yourself!
1. Restart your Internet Router
Restarting your router will terminate all the processes it is doing and clear all the cache. Thus it improves the performance tremendously.
To restart your router follow the steps below:
- Login to the Xfinity app on your phone.
- Select your modem.
- Tap on “Restart this device.”
Or you can also visit Xfinity’s website and restart from there as shown below.
It’s that simple. You can do it manually if you don’t have the Xfinity app.
- Please turn off your router and unplug it from the outlet.
- Now, wait for 30 seconds.
- After 30 seconds, plug it back in and turn it on.
It’s that simple.
2. Update your Router Firmware
It depends on which brand router you are using. You can go to their website and find guides about updating the firmware of a specific router.
Most of the time, updating a router’s firmware is identical in almost all of the latest routers.
- Login to your Router using the Gateway IP Address. (Login credentials can be found on the back of the router.)
- Go to the Update section.
- Click on “Check for updates,” and your router will automatically find the latest firmware and will update itself.
If you are using Xfinity’rs xFi routers, you can also do it from the mobile app.
Login to your Xfinity mobile app, select your router, tap on “Update this device.” and you are done.
3. Upgrade your Modem
If updating your router/modem to the latest firmware is not solving the issue, then upgrading will.
Gone are the days when 10-25 Mbps connections were considered a luxury; Xfinity offers packages up to 1 Gbps.
Because the internet is so improved nowadays, and if you are still using those old network devices, you might have to take some money out of your pockets.
Likewise, if you have a modern router but a low-speed internet connection, that network will struggle too.
Because the hardware and latest networking tech are designed to complement each other, if the router is old and the internet is advanced, the router will not be able to handle the modern internet speed.
In layman’s language, If the router is modern and you have a 10mbps connection, then it will not be able to process such a low data frequency as it is not designed to do so.
Other than that, the old routers are also not designed to manage more than three network devices.
To fix it, you must study the Xfinity plan you are using. I suggest buying the router from Xfinity; as they provide you with the internet, they will help you choose the best router to go with their services.
I always suggest upgrading your routers and network devices every three years to prevent this issue from happening again.
4. Replace Old Devices
If you are facing slow internet on specific devices, and only when they are connected to a WiFi network.
That indicates that the WiFi chip on your devices is not advanced enough to support the high Internet speeds.
The technology prevents the device from using your internet to its full extent.
A 4G device with a 5G network would be an example. The 4G device won’t fully utilize the speed of the 5G network.
If that is the case, replacing your old devices is only the possible solution!
5. Get a better Internet Plan
So, your foe might be your internet plan if you are still struggling with your internet speed.
The best and probably the most expensive solution is to get a better Xfinity internet plan with higher internet speeds.
While getting a high-speed internet plan, make sure you buy the hardware to go along with that so you do not face network congestion again.
Xfinity not getting Full Speed: Conclusion
Concluding it all, the network congestion will cause slow internet speeds, either from the Xfinity side or your home network. To fix it, you might have to update your router or upgrade it for future-proofing.
You can set up a wired connection and extensions for applications that require a lot of bandwidth to get the fastest speed. (It is always recommended.)
