  • Place computers close to WiFi router
  • Close other network-heavy applications
  • Use WiFi 6 router for maximum speed

Method 2: Ethernet Cable (Fastest Wired)

Direct ethernet connection between computers. Speed: up to 1 Gbps (125 MB/s).

Setup:

  1. Get an Ethernet crossover cable (or regular cable with modern NICs)
  2. Connect both computers directly
  3. Configure static IP addresses:
    • Computer 1: 192.168.1.1
    • Computer 2: 192.168.1.2
    • Subnet mask: 255.255.255.0
  4. Enable file sharing on both computers
  5. Access shared folders via network

Best For:

  • Transferring 10GB+ files regularly
  • Desktop-to-desktop transfers
  • Maximum speed requirement
  • Stable connection needed

Method 3: USB Drive/External SSD (Fastest for Huge Files)

For files larger than 50GB, physical transfer is often fastest.

Speed Comparison:
