If your uploading figure is below that level, your connection needs attention.

Good Upload Speed : 80-100% of Promised

Pre-Check For Any Errors & Speed

Before you start troubleshooting or came to any conclusion on the speed of upload, it is always better to check the speed.

You can use the following to check your “Upload Rate”

1. Check Other Website

First, check the upload rate on another website. Sometimes it may happen that a particular website may be slow. So, better check from other websites.

2. Use Speed-test Tools

You can use any tool of your choice to find the uploading rate of your Internet. But we suggest you use the Speed test tool to check your Internet.

3. Ethernet Cable

It is better to perform a speed test when the device is connected to the Ethernet Cable.

4. Check from Neighbours

It is always a good option to check with your neighbor (using Xfinity) to check for their upload rate. This way you can be sure that the problem exists not only for you but in the whole area.

If the rate is constantly 80% below the promised figure of your subscription, this means that your Internet is constantly slow.

Why is Xfinity Upload Speed so Slow?

A slow uploading speed is always painful. This can happen due to many reasons.

Let us discuss the main reasons for getting a slow uploading rate.

# Cap by Internet Provider 

Many times the Internet provider places a data cap on the uploading as well as downloading. This data cap varies from plan to plan.

# Firewall

Using a third-party firewall system can also lead to uploading errors. Use default firewall.

# Business Restrictions

If you are working for a Company, chances may be there that the Company may have put restrictions on uploading and downloading caps.

# Defective Modem or Router

Check the modem and router for any faults. This can also lead to Internet fluctuations.

How to Increase Xfinity Upload Speed 

When your uploading rate is lagging too much or below your desired level, it can be quite disappointing. 

To increase, try these proven techniques:

Step 1. Use Ethernet Cable

Sometimes there may be a problem with your router. If you have been using Wi-Fi, disable it and use an Ethernet cable to connect your PC to the modem.

Step 2.  Update your PC

Make sure you update your PC to the latest software, especially the network drivers.

The old and obsolete drives may create speed problems. Also, update the version of your computer’s operating system to the latest one.

Step 3. Scan your PC

Scan your PC for malware or Adwares. Adwares has become famous for making your PC slow. To solve this problem, you can scan your PC with some good antimalware software like Malwarebytes, etc.

Step 4. Check your Package

It may happen that the plan or package that you subscribed may provide a low upload rate. In that case, go for a good package with a better upload rate.

Step 5. Check your Modem

Check your Modem for any loose cable or nuts. Also, check for loose wirings. This also can lead to data loss. If your modem has errors, repair it or better replace it.

Step 6. Stop Sharing

If your Internet is shared by all your family members or your colleagues, surfing limits are bound to decrease. In that case, stop all the sharing when you need to do uploading work.

Step 7. Use Antivirus

Use a good antivirus and always update it. Antivirus can detect hidden issues and show you error notifications.

Step 8. Clean your PC

Due to prolonged use, PCs accumulate a huge amount of temporary files. Remove all these files. To make things easier, you can use PC cleaner software.

Step 9. Stop Background Data Use

Make sure you check whether your system or any software is using data in the background.

For example, Windows itself downloads data in the background for system updates. The same is in the case with ‘Torrent’ or similar websites.

These websites downloads and upload at the same time as they depend on peer-to-peer system of download. So, stop these processes.
