Can't connect your scanner to your computer? Printer won't show up on the network? You're not alone. Network connection problems are frustrating, but they're usually easy to fix once you know what to look for.
What is Network Checker?
Network Checker is a simple tool that helps you understand why two devices can't connect. It checks if your devices are on the same network by comparing their IP addresses.
Quick Start
- 1. Enter device names (e.g., "Scanner", "My Computer")
- 2. Type IP addresses (find in Settings → Network)
- 3. Click "Check Connection"
- 4. Follow the fix steps
Common Problems & Solutions
Problem: Different Networks
This is the most common issue. Your devices are connected to different networks.
How to fix:
- • Find which device uses wired connection
- • Connect other devices to the same router
- • Use wired cable if possible (more stable)
Problem: Same Network But Can't Connect
Devices are on the same network but still can't connect? Check these:
- • Firewall settings (allow file sharing)
- • File sharing enabled on both devices
- • Correct folder permissions
- • Both devices turned on
Understanding IP Addresses
An IP address looks like this: 192.168.1.100
The first three numbers (192.168.1) identify the network. The last number (100) identifies the specific device. For devices to connect, the first three numbers must match.
✓ Same network:
Device A: 192.168.1.100
Device B: 192.168.1.200
✗ Different networks:
Device A: 192.168.1.100
Device B: 192.168.11.27
