Getting the most out of RAN Community starts before you even log in. Windows ships with network settings designed for everyday browsing — not for persistent online game connections. Running our one-click setup tool takes less than a minute and gives your PC the best possible foundation for stable, low-ping gameplay.
This guide walks you through everything, step by step.
What You’ll Need
- A Windows 10 or Windows 11 PC
- The RAN Community game client installed
- About 2 minutes of your time
No technical knowledge required. The script handles everything automatically.
Step 1: Download the Setup Tool
The connection optimizer is included in your game client. You can find it in two places:
Option A — Already in your game folder:
Navigate to your RAN Community installation folder and open the vcredist folder. You’ll see:
RanCommunity_Connection_Fix.bat— runs the optimizationRanCommunity_Connection_Fix_Revert.bat— undoes everything if needed
Option B — Download the ZIP:
If you prefer a clean standalone copy, download it directly from our website:
🔗 Download Connection Fix Tools
Extract the ZIP anywhere, then follow the steps below.
Step 2: Run as Administrator
- Right-click
RanCommunity_Connection_Fix.bat - Select “Run as administrator”
- Read the intro screen — it lists everything the script will do
- Press any key to begin
- Wait about 30 seconds for all 13 steps to finish
- Restart your PC
That’s it. Your PC’s network is now tuned for online gaming.
Heads up if you use a VPN: After rebooting, reconnect your VPN once. It will work normally from that point — the script doesn’t remove VPN software.
What the Script Actually Does
The tool makes 13 targeted adjustments to your Windows network settings. Here’s what each one does in plain language:
| # | What it changes | Why it matters |
|---|---|---|
| 1 | Disables Nagle’s Algorithm | Sends your game packets instantly instead of bundling them |
| 2 | Extends TCP Keep-Alive to 60 seconds | Keeps your connection alive during loading screens and AFK moments |
| 3 | Increases TCP port range | Supports multiple game clients without running out of ports |
| 4 | Disables TCP Auto-Tuning | Stops Windows from resizing your connection buffer mid-session |
| 5 | Disables Receive Segment Coalescing | Packets arrive one at a time instead of being batched |
| 6 | Disables NIC Power Management | Prevents Windows from sleeping your network card to save power |
| 7 | Removes Network Throttling | Gives RAN Community full access to your available bandwidth |
| 8 | Disables Delivery Optimization | Stops Windows from uploading updates to nearby PCs using your connection |
| 9 | Extends DNS Cache | Speeds up reconnects after any brief drop |
| 10 | Disables Large Send Offload | Bypasses NIC firmware that sometimes corrupts packets |
| 11 | Disables WiFi Auto-Connect | Prevents Windows from switching you to a different network mid-game |
| 12 | Adds Firewall Exceptions | Makes sure Windows Firewall never silently blocks Game.exe |
| 13 | Flushes DNS + Resets Winsock | Clears any stale network state as a one-time clean baseline |
None of these changes affect your game files. Only Windows network settings are modified.
Before making any changes, the script automatically saves a snapshot of your current settings to a _ConnectionFix_Logs folder inside your game directory. This is useful if you ever need to report a network issue to our support team.
Is It Safe?
Yes. Here’s why:
- Every setting is a standard, documented Windows configuration key
- Nothing is permanently deleted — all changes are values added or updated in the Windows registry
- The revert script (
RanCommunity_Connection_Fix_Revert.bat) restores every single setting to Windows defaults with one click - Settings that don’t apply to your hardware are silently skipped
- Works on Windows 10 and Windows 11
Step 3: Switch to Ethernet if You Can
WiFi is convenient, but a wired Ethernet connection is significantly more stable for online gaming. Even a basic cable makes a difference:
- More consistent ping with fewer spikes
- No interference from microwave ovens, Bluetooth devices, or neighboring WiFi networks
- No risk of Windows quietly switching you to a different network
If your gaming PC is far from your router, a powerline adapter is a great middle ground — it sends your internet connection through your home’s electrical wiring.
Step 4: Reduce Background Bandwidth Usage
Even after the script runs, background applications can compete for your bandwidth:
- Pause Windows Update during sessions: Settings → Windows Update → Pause for 1 week
- Close torrent and P2P clients before launching the game
- Pause cloud sync (OneDrive, Google Drive, Dropbox) while playing
- If your router has QoS (Quality of Service), enable it and prioritize your gaming PC
How to Undo Everything
Changed your mind? No problem.
- Open your
vcredistfolder (or wherever you extracted the ZIP) - Right-click
RanCommunity_Connection_Fix_Revert.bat - Select “Run as administrator”
- Wait for all 13 steps to complete
- Restart your PC
Every setting returns to its original Windows default.
Antivirus Exclusions
Some antivirus programs (Avast, AVG, Kaspersky, and others) inspect every network packet in real time, adding latency to your game. Add your entire RAN Community game folder to your antivirus exclusion list to avoid this overhead.
Router Restart
Routers accumulate connection state over weeks of uptime. A quick restart — unplug for 30 seconds, plug back in — every couple of weeks keeps your home network healthy.
Quick Ping Test
To check your general connection quality, open Command Prompt and run:
ping rancommunity.com -n 20A healthy result shows under 100ms average and 0% packet loss. If you see packet loss or unusually high ping consistently, that’s an ISP-level issue worth reporting to your internet provider.
For Advanced Players: Verify the Changes
After running the script and rebooting, you can confirm the key settings are active using Command Prompt.
TCP Auto-Tuning (should read “disabled”)
netsh int tcp show globalNagle’s Algorithm (should show 0x1 on your active adapter)
reg query "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces" /s /v TCPNoDelayTCP Keep-Alive (should show 0xea60 = 60 seconds)
reg query "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" /v KeepAliveTimeNetwork Throttling (should show 0xffffffff = disabled)
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile" /v NetworkThrottlingIndexDownload
| File | What it does |
|---|---|
RanCommunity_Connection_Fix.bat | Applies all 13 network optimizations |
RanCommunity_Connection_Fix_Revert.bat | Restores all settings to Windows defaults |
Both files are included in the vcredist folder of your game client, or available as a standalone ZIP download above.
See you in-game, Legends!
