Windows 11 Network Settings — The Complete Guide for Small Offices

Overview

Windows 11 has distributed network settings across multiple locations: the Settings app, Control Panel (still present but less prominent), Device Manager, and the Network Profile system. For a small office maintaining reliable file sharing, knowing where each setting lives — and what it does — saves significant troubleshooting time.

This guide covers every relevant setting for small office file sharing in one reference.

1 — Network Profile Type

Where: Settings → Network and Internet → click your active connection (Ethernet or WiFi) → Network Profile Type

Options:

• Private network: Enables network discovery and file sharing. This is what you want for your office connection.
• Public network: Disables discovery and sharing. Windows defaults to this when connecting to a new network.
• Domain network: Set automatically when joined to an Active Domain Controller. Not relevant for most small offices.

What it affects: Everything. Setting this incorrectly is the single most common cause of file sharing failures.

Set to: Private for your office connection.

2 — Advanced Network Sharing Settings

Where: Settings → Network and Internet → Advanced Network Settings → Advanced Sharing Settings

Private Networks section — what to set:

• Network Discovery: On
• File and Printer Sharing: On

All Networks section:

• Public Folder Sharing: On or Off depending on whether you use the Public folder
• Password Protected Sharing: On (recommended) — requires credentials for share access

What it affects: Whether other machines can see your machine and access your shared folders.

3 — Windows Firewall Allowed Apps

Where: Control Panel → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall

Ensure these are checked for Private network:

• File and Printer Sharing
• Network Discovery
• (If using Remote Desktop) Remote Desktop

What it affects: The firewall blocking legitimate LAN traffic. Third-party antivirus products install their own firewall rules that may need separate configuration.

4 — Services (The Core Four)

Where: Win+R → services.msc

These four services must be set to Automatic startup and be Running:

Service name	What it does
Function Discovery Resource Publication (FDResPub)	Publishes your machine to others on the network
SSDP Discovery (SSDPSRV)	Handles SSDP multicast announcements
UPnP Device Host (upnphost)	Hosts UPnP device services
DNS Client (Dnscache)	Required for mDNS/LLMNR name resolution

Check startup type: Right-click each → Properties → Startup type must be Automatic (not Manual or Disabled).

5 — Network Adapter Advanced Settings

Where: Device Manager → Network Adapters → right-click adapter → Properties → Advanced tab

Settings to check:

Speed and Duplex: Should be "Auto Negotiation" or explicitly "1.0 Gbps Full Duplex" for a gigabit connection. If set to 100 Mbps, transfer speeds are capped at ~11 MB/s.

Energy Efficient Ethernet (EEE): Can occasionally cause link flapping on some routers. If you experience intermittent disconnections, try disabling this.

Jumbo packet / Jumbo Frames: If your switch supports jumbo frames (MTU 9014) and all devices on the segment support it, enabling this can improve large file transfer throughput. If only some devices support it, leave it off.

Power Management: Device Manager → Network Adapter → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power." This prevents the adapter from going to sleep during inactive periods.

6 — WiFi Adapter Settings

Where: Device Manager → Network Adapters → WiFi adapter → Properties → Advanced

Transmit Power: Ensure set to Highest or 100% — some laptops reduce WiFi transmit power to save battery, reducing range and throughput.

Preferred Band: For 802.11ac/WiFi 5 and WiFi 6 adapters, prefer 5 GHz when available. 5 GHz offers more throughput and less interference than 2.4 GHz.

Roaming Aggressiveness: On laptops that move around the office, Medium or High roaming aggressiveness improves handoff between access points when walking through the space.

7 — SMB Configuration (PowerShell)

For advanced users who want to verify or adjust SMB settings.

Check which SMB versions are enabled:

Get-SmbServerConfiguration | Select-Object EnableSMB1Protocol, EnableSMB2Protocol

SMB1 should be False. SMB2 should be True.

Check active SMB connections and their version:

Get-SmbConnection

View current SMB server settings:

Get-SmbServerConfiguration

8 — IP Address Configuration

Where: Settings → Network and Internet → your connection → scroll to IP assignment

DHCP (recommended for most offices): Your router assigns IP addresses automatically. Machine IP addresses may change if the machine is off for a long time or the router is reset. To avoid this: log into your router and reserve a specific IP address for each machine (DHCP reservation based on MAC address).

Static IP (alternative): Manually set a fixed IP, subnet mask, gateway, and DNS on each machine. More stable than DHCP without reservations but requires manual management.

For reliable UNC paths (e.g., \\HOSTNAME\Projects): either DHCP reservations or static IPs prevent the scenario where a machine's IP changes and connections break.

9 — Hosts File (Name Resolution Override)

Where: C:\Windows\System32\drivers\etc\hosts (edit with Notepad run as Administrator)

If machine name resolution via DNS/LLMNR is unreliable, you can add static entries to the hosts file:

192.168.1.45    DESKTOP-OFFICE1
192.168.1.46    DESKTOP-OFFICE2

This bypasses the name resolution service entirely for those machine names, making \\DESKTOP-OFFICE1\Projects resolve reliably regardless of whether mDNS/LLMNR is working.

10 — Network Reset (Last Resort)

Where: Settings → Network and Internet → Advanced Network Settings → Network Reset

This resets all network adapters, removes manually added network adapters, and returns network settings to defaults. Use as a last resort for a machine that has persistent networking issues that other fixes have not resolved.

Effect: You will need to reconnect to WiFi networks, re-enter credentials for network shares, and reconfigure any static IP settings.

Mac Reference

For Mac users in mixed environments, the equivalent key settings:

Windows setting	Mac equivalent
Network Profile (Private/Public)	System Settings → Network → Firewall → (no profile concept — sharing is per-service)
File Sharing	System Settings → General → Sharing → File Sharing
Connect to Windows share	Finder → Go → Connect to Server → smb://IP/ShareName
Network link speed	System Settings → Network → Details → Hardware → Speed
IP address	System Settings → Network → Details → TCP/IP → IP Address

Get Oxolan for Windows — works without any of the above configuration

Frequently Asked Questions

Where did the old Network and Sharing Centre go in Windows 11? It is still accessible via Control Panel → Network and Internet → Network and Sharing Centre. Microsoft moved most settings to the Settings app but kept the Control Panel path functional.

Can I access these settings remotely on another machine? For machines you manage: Windows Remote Management (WinRM) allows PowerShell commands including service and network configuration remotely. Requires prior setup and network access.

Why do my settings reset after a Windows Update? Some cumulative updates include configuration baseline changes that reset service startup types and occasionally other settings. The post-update checklist in our Windows Networking Checklist article covers the most common resets.

Is there a single command to fix all the common file sharing issues? Not officially. The four services restart command (PowerShell) handles the most common services issue. For a more comprehensive reset of sharing services, running netsh winsock reset, netsh int ip reset, and rebooting clears many network configuration issues at the cost of resetting custom TCP/IP settings.
