If you're having trouble connecting to (or staying connected to Core), these basic troubleshooting steps are a good way to check for simple things that may be impacting your connection. 

Switch to a Wired Connection

For many connection issues, the main culprit could be a weak wireless signal from your router.  The best way to determine if this is causing your connection issue is to try to plug your PC directly into your router with an ethernet cable. 

This is especially important if you are playing from a significant distance away from your router, as the signal will be weaker the further you are.  If you can't switch to a wired connection, try moving closer (ideally within the same room) to your router.

Disable Non-essential Programs/Processes

A lot of us like to multi-task while gaming, however, having multiple programs open (as well as Core) could result in degraded network performance.  Commonly used programs such as Twitch, Youtube, Chrome/Firefox, and Discord can take significant bandwidth to run simultaneously, so shutting these programs off may help your connection strength (especially on a wireless connection). 

To review your open processes and disable them:

1. Hit the Windows key
2. Type "Task Manager", and click the app that shows up
3. You'll see a list of all running programs and the amount of system resources they are using:
   ​
4. Depending on the resource you are trying to free up, you can sort each column (CPU, Memory, Network, etc.) by clicking the top of the column.  Sort in descending order to find the most resource-intensive programs.
5. Select a program that you aren't currently using, and hit End Task in the bottom right to close the program and free up the system resources it's consuming. 

Shut off VPN Services

If you're using a VPN service, it's possible that it is interfering with the communications to our patching/network servers.  Try temporarily turning your VPN off to see if it helps with connecting to Core.

Update Network Drivers

It's possible that you may have outdated Network Drivers which could be causing trouble in trying to play Core. 

To update your Network Drivers:

1. Press the Windows Key
2. Type "Device Manager" and click the app that shows up
3. Find the "Network Adapters" category and expand it by clicking the ">" next to it
4. Right click the Network Adapter that you're using and click "Check for Updates" (in most cases, this will be the "Ethernet" or "Wifi" adapters)
5. If asked, select "Search for Updates Automatically"
6. On the next screen, select "Search for updated drivers on Windows Update"

Generally, it's a good idea to update your Windows from time to time to ensure that you have the latest security updates.  Some times, these may block network functionality due to security purposes.

Run as Administrator

Sometimes Core may be blocked from running properly if your PC does not think you have permissions to run the program.  This can by bypassed by running the game as administrator.  To do this:

1. Find the shortcut to Core and right-click it
2. Select "More" from the options
3. Click "Run as Administrator"

This should launch the game as Administrator, which may stop the game from blocking access to playing properly.

Sending NetworkInfo Logs

If these basic troubleshooting steps fail, our support team may ask you to provide a Network Info log so we can take a deeper look at what's going on with your connection.  To get a NetworkInfo log:

• Press the [Windows Key]
• Type cmd in the search bar and click "Ok". You should now see a black window with white letters.
• Highlight and copy (or Ctrl+C) the following text (all of it, including quotes and parenthesis):

(ipconfig /all & ping www.google.com & netsh firewall show config & netsh interface ipv4 show subinterfaces & netsh interface ipv4 show ipstats) > "%USERPROFILE%\desktop\NetworkInfo.txt"

• Paste this into the cmd window by right clicking.
• Press Enter.
• After a few seconds, it should generate a NetworkInfo.txt file on your desktop.
• Attach the NetworkInfo.txt to your support ticket.
