While browsing the internet, you may see a browser prompt that says “This website wants to look for and connect to devices on your local network”. This message can appear suddenly and often confuses users, especially because it sounds like a privacy or security risk.
This prompt is shown by modern web browsers when a website tries to discover or communicate with devices on your local network, such as printers, smart TVs, media servers, routers, or other connected devices. The request itself does not mean your system is infected, but it should always be handled carefully.
What Does This Message Mean
This message appears when a website uses browser technologies that allow local network access.
- The website is requesting permission to scan your local network
- It may be trying to find devices like printers, Chromecast, or smart TVs
- The browser blocks this by default and asks for your consent
- Permission is granted per website, not system-wide
The browser shows this warning to protect your privacy and network security.
Why Websites Ask to Access Your Local Network
Some websites genuinely need this access to function properly.
- Online printer configuration pages
- Media streaming and casting websites
- Router or NAS web dashboards
- Smart home device setup pages
- Local web apps running on your own PC
In these cases, allowing access is expected and safe if you trust the website.
How to Decide Whether to Allow or Block the Request
You should decide based on trust and purpose.
- Allow only if you recognize and trust the website
- Allow if you are intentionally setting up or controlling a local device
- Block if the website is random, unknown, or unrelated to devices
- Block if you are simply browsing content
Blocking the request usually does not break normal websites.
How to Allow Local Network Access (If You Trust the Website)
If the website needs access to local devices.
- Read the permission prompt carefully
- Click Allow only if you initiated the action
- Continue using the site as intended
The browser will remember this permission for that website.
How to Block Local Network Access (Recommended for Most Sites)
Blocking is the safest option for unknown websites.
- Click Block when the prompt appears
- Continue browsing normally
- The website will not be able to scan or connect to local devices
Blocking does not affect your PC or internet connection.
How to Change Local Network Permissions Later (Chrome / Edge)
You can review or revoke permissions anytime.
- Open the website in your browser
- Click the lock icon next to the address bar
- Open Site settings
- Find Local network access or similar permission
- Change it to Block or Ask
Changes take effect immediately.
How to Disable This Prompt Completely (Advanced)
If you never want websites to request this access.
- Open browser Settings
- Go to Privacy and security
- Open Site settings
- Review experimental or advanced permissions
- Disable local network discovery options if available
Note that not all browsers allow full disabling.
Is This a Security Risk
In most cases, the prompt itself is not a threat.
- Browsers sandbox websites for safety
- Websites cannot access devices without permission
- Blocking prevents any network scanning
- Trusted sites use this only for specific features
The risk comes only from allowing access to untrusted websites.
When You Should Be Concerned
Take extra caution if:
- The prompt appears on a suspicious or unknown website
- You did not initiate any device-related action
- The site content does not justify local access
- Multiple prompts appear repeatedly
In such cases, block the request and close the site.
Final Thoughts
The message “Website wants to look for and connect to any device on your local network” is a standard browser security prompt designed to protect you. It does not mean your computer is compromised. It simply asks for permission before a website can interact with devices on your network.
As a rule of thumb, only allow this permission for trusted websites and only when you need device-related features. For everyday browsing, blocking the request is the safest and recommended choice.
