WARNING: If you have set up a Data bandwidth usage limit prior to the update, your download speed will be limited to the value selected—5Mbps, 20Mbps, or 40Mbps. To change your Data Bandwidth Usage Limit back to Unlimited, you will need to wait for the new update to install. Once the update is installed, please do the following:
If you haven't set up a Data bandwidth usage limit prior to the update or are downloading the packages for the first time, make sure to use an ethernet cable instead of wifi, even if your wifi is stable. A wired connection greatly reduces the risk of packet losses.
NOTE: If the download does not progress, see Download stuck on packages / Install loop instead.
If you are experiencing slow download speed when downloading or updating Microsoft Flight Simulator, please do the following:
|RESTART THE DOWNLOAD|
If the download slowed down, close the app to restart the download—the download will resume from where it left off.
|REBOOT YOUR ROUTER OR MODEM|
- Unplug your router or modem from its power outlet.
- Wait at least 60 seconds.
- Plug your router or modem into the power outlet.
- Your router or modem will take a few minutes to reinitialize.
|DISABLE AUTOTUNING LEVEL|
- In the "type here to search" bar, next to the Windows Start menu icon, type Command and look for Command Prompt
- In the menu select “Run as administrator”
- Enter: netsh int tcp set global autotuninglevel=disable
- Press enter
- Reboot your computer
- In the "type here to search" bar, next to the Windows Start menu icon, type Delivery optimization
- Select Open
- Click on Advanced Options
- Check the box "Limit how much bandwidth is used for downloading updates in the background" and move the slider to 100%.
1. Right-click on the “Network / Wi-Fi ” icon on the bottom right corner of your screen to open up the menu shown below.
2. Click on Open Network and Sharing Center.
3. In the Network and Sharing Center window, click on Change adapter options.
4. You will then see a list of network adapters available on your computer.
5. Right-click on your active network adapter (Ethernet or Wi-Fi) and select Properties.
6. In the Properties window, scroll down until you see Internet Protocol Version 6 (TCP/IPv6).
Note: If you’re connected to the internet wirelessly, the corresponding adapter should be “Wi-Fi“. However, if you’re connected to the internet via a LAN cable instead, the corresponding adapter should be “Ethernet“.
7. Uncheck the Internet Protocol Version 6 (TCP/IPv6) checkbox and click on OK to save the changes.
Now that IPv6 has been disabled on your computer, reboot your computer for the setting to take effect.
Some users reported that using Netlimiter and setting the download speed between 5 and 20 Mbps helped them bypass the looping issue.
Internet throttling is when your Internet Service Provider (ISP) limits your internet bandwidth or speed.
Reasons why your ISP might throttle your internet speed:
An ISP can reduce the internet speed of everyone located in a specific area during times of heavy internet use. If your download speed is fine from 10 a.m. to 6 p.m. but sluggish between 6 p.m. and 11 p.m. your ISP likely throttles your internet speed during peak hours.
Some ISPs will limit how much high-speed data you can use in a billing cycle. Going over that cap will result in some bandwidth throttling. Double-check your contract or contact your ISP support line to know what your data cap is.
This is when your ISP throttles certain types of data because it takes up a lot of bandwidth.
Typically, if your internet speed is fast when downloading a small amount of data but becomes very slow when downloading a large amount of data, your ISP is likely penalizing you for using up a lot of bandwidth.
How to test if your internet is being throttled.
To test if your internet is being throttled you can try using a VPN to prevent your ISP from seeing what kind of traffic is coming and going on your line.
Run a speed test without VPN then run the speed test again using a VPN.
If your connection is significantly faster with the VPN, your ISP is likely throttling your service. If that's the case, contact your ISP to discuss the issue.
