Pre-Build Checklist

  • Confirm router capability before buying latest Wi-Fi hardware.
  • Use external antennas with good placement for desktop towers.
  • Install latest stable networking drivers.
  • Prefer Ethernet for latency-sensitive competitive workloads.

Build Steps

Expandable runbook sections

  1. 1

    Assess current wireless bottleneck

    Info
    v

    Check whether bottleneck is adapter generation, router capability, channel congestion, or poor antenna placement.

  2. 2

    Install and position hardware correctly

    Info
    v

    Place antennas away from metal obstructions and tune adapter settings after driver installation.

  3. 3

    Set realistic expectations

    Warning
    v

    Wireless upgrades improve convenience, but wired Ethernet remains preferred for lowest-latency and highest-stability scenarios.

Commands & Validation

Use these commands for post-build validation and troubleshooting.

Check Wi-Fi adapter and signal info (Windows)

CMD

netsh wlan show interfaces
netsh wlan show drivers

Safety Notes

  • Validate compatibility in manufacturer QVL and support pages before purchase.
  • Do not disable Secure Boot, TPM, or endpoint protections to work around instability.
  • Use official BIOS/firmware sources only and avoid beta firmware on production systems.
  • If a component arrives damaged or fails burn-in testing, process an RMA instead of forcing deployment.
