  • Right-click your Wi-Fi adapter (Killer or Intel) → Update Driver
  • Choose Search automatically for updated driver software

Alternatively, download drivers from Dell’s official support page.

2.2 Update BIOS

  • Outdated BIOS can cause hardware miscommunication.
  • Visit Dell’s support site → enter your laptop’s Service Tag → download the latest BIOS update.

2.3 Update Router Firmware

  • Log in to your router’s admin page (usually 192.168.1.1)
  • Check for firmware updates → install if available.

Section 3: Optimize Windows Settings

3.1 Disable Power Saving for Wi-Fi

  • Open Device Manager → Network Adapters
  • Right-click Wi-Fi adapter → Properties → Power Management
  • Uncheck “Allow the computer to turn off this device to save power”

3.2 Change DNS for Faster Browsing

  • Go to Control Panel → Network and Sharing Center → Wi-Fi → Properties → Internet Protocol Version 4 (TCP/IPv4)
  • Set DNS manually:
    • Google DNS: 8.8.8.8 and 8.8.4.4
    • Cloudflare DNS: 1.1.1.1 and 1.0.0.1

3.3 Adjust Band Preference

  • Many early XPS 15 models struggle with 2.4 GHz networks due to congestion.
  • Force connection to 5 GHz by:
    • Device Manager → Network Adapter Properties → Advanced → Preferred Band → Select “5 GHz”

Section 4: Router & Network Optimization

4.1 Change Router Channel

  • Many routers automatically assign channels, but manual selection can reduce interference.
  • For 2.4 GHz, use channels 1, 6, or 11.
  • For 5 GHz, try 36, 40, 44, or 48.

4.2 Enable QoS (Quality of Service)

  • In your router settings, prioritize your Dell XPS 15’s MAC address for stable performance.

4.3 Position Router Correctly

  • Place router in a central, elevated location.
  • Keep away from thick walls and other electronics.

4.4 Use a Mesh Wi-Fi System

  • If your home has dead zones, a mesh Wi-Fi system can ensure stable coverage.

Section 5: Hardware Tweaks for Early XPS 15

5.1 Replace Wi-Fi Card

  • Some early XPS 15 models used Killer Wireless cards, which had reliability issues.
  • Replacing them with Intel AX200 or AX210 Wi-Fi cards drastically improves stability and speed.

5.2 Use USB Wi-Fi Adapter

  • If upgrading the internal card isn’t an option, a high-quality USB Wi-Fi adapter is a quick fix.
