My Xfinity upload speed is really poor; what gives?

If your Xfinity connection is sluggish, it might be due to one of two things: You haven’t subscribed to a plan that provides a fast enough connection speed. Despite paying for a high-speed internet package, you aren’t experiencing the promised download and upload times.

The majority of services have faster download speeds, while upload rates are often in the 10 Mbps range.

Ideal upload times would be many hours for raw video files that are in the hundreds of gigabit range. However, at 300 Mbps, it would be finished in a few minutes.

Many employees must simultaneously upload and download files for business purposes. Here is when upload speed is most crucial. Additional faster upload rates are required for:

  • Taking lessons online and turning in homework
  • People who video conference
  • Playing games online
  • Backing up crucial information
  • Applications like Dropbox, Google Docs, etc.

Attending Online Classes

Online courses have gained popularity recently. A variety of online platforms are used for the classes that students must attend.

Log-in games caused by slow upload rates can impair your performance. Additionally, Twitch, where you can broadcast your games to a huge audience, requires a fast upload speed.

Keeping Important Data Safe

We never want to lose any of the significant photos, films, or files we have. They might be lost, though, if a bug in your device causes it to happen.

Therefore, a faster upload speed is needed to back up these data to your Google Drive or cloud storage.

Certain Apps

If you’ve used Google Documents, Dropbox, etc., you are aware that as soon as you enter data, it is immediately uploaded.

Working on these apps won’t be enjoyable if the pace is slow because of this.

The symmetrical speeds of the most recent connections, particularly fiber connections, are one of their advantages. Their download and upload speeds are therefore equal.


We are aware of how frustrating it is to wait hours for a straightforward video upload. The best place to start when diagnosing the issue is with the internet service provider.


Numerous other factors, such as your router, software, and the number of connected devices, may also be to blame. A slow upload rate might occur for a number of reasons. Which are:

  • Data Limits
  • external firewalls
  • Business Restrictions
  • faulty modem or router
  • A surplus of connected devices

Let’s investigate the specifics.

Data Limits

The issue can result from limitations and problems on the part of your service provider. For instance, they might impose data limitations, which would limit uploading and downloading.

The data limit will change depending on the plan you select. To remedy this problem, it would be better if you got in touch with them.

Third-Party firewalls

Your device’s third-party firewall or antivirus software may also cause problems and slow down your internet. When you utilize your own firewall in place of the PCs’, this typically occurs.

It makes the device slower by checking every file while it is being uploaded or downloaded.

Simply remove the current firewall to see if the speeds have increased. Find a better firewall for your device if the answer is yes.

Business Restrictions

Your access to data may occasionally be restricted by the company you work for. For instance, they might impose data limitations that limit your ability to upload and download.

Faulty Modem Or Router

A reduced speed may be caused by the modem’s physical condition and the firmware that has been placed inside. Your router may become outdated or pick up problems over time. Keeping it current could be a remedy to performance pro.

If you’re interested, we’ve put together a list of the top Xfinity mobile modems. To avoid this, keep updating your firmware.

Your devices may become sluggish as a result of spyware or viruses on your router or other devices. Viruses can slow down a computer’s performance by running programs in the background that consume data to extreme pro.

A Surplus Of Connected Devices

Your internet speed may also be impacted by the number of devices you have connected. The number of devices that are currently connected will also slow down the connection speed.

Monitor and restrict the number of devices using your Wi-Fi. You may accomplish this by utilizing a variety of apps in your 4k streaming device or any connected device.

Remark: If your internet speed is 80% slower than what your provider promised, that indicates that it needs to be improved.
