Note: Before attempting the steps below, make sure to use an ethernet cable instead of wifi, even if your wifi is stable. Some users reported that using a wired connection immediately fixed the problem.
If you have reached your Data limit cap you might be prevented from downloading additional data. The data cap will reset at the date you have set up. By default, it should be on the first day of every month, unless you have selected a different day.
If you are experiencing slow download speed when downloading or updating Microsoft Flight Simulator, please do the following:
|DISABLE AUTOTUNING LEVEL|
- In the Windows search bar, 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
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.
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“.
6. In the Properties window, scroll down until you see Internet Protocol Version 6 (TCP/IPv6).
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.
|MAKE SURE YOU HAVEN'T SET UP A DATA BANDWIDTH USAGE LIMIT|
If you set up a Data bandwidth usage limit your download speed will be limited to the value you have set up (5Mbps, 20Mbps or 40Mbps.)
To set up your Data Bandwidth Usage Limit to unlimited, please do the following:
- Launch Microsoft Flight Simulator
- Go to Options > General > Data
- If the bandwidth is set to 5Mbps, 20Mbps or 40Mbps move the cursor to Unlimited
- Apply and Save
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.
- Make sure that your hard drive doesn't go into sleep mode
- Close the app and restart it rather than letting it hang. Note: the download will resume from where it left off (you will not have to download from the start again.
- Turn off any security software that may be interfering (UAC, Antivirus, Firewall).
- Change the installation repository (from C: to D: for instance) or try creating a new installation folder in the drive of your choice (for instance create "MSFS" in your C: drive)
