FirstEverTech/Universal-Intel-WiFi-BT-Updater v2026.04.0005

v2026.04.0005 - Release Notes

on GitHub

🚀 Release: v2026.04.0005

🐛 Bug Fix

• Critical: Versioned Release Asset Download Failure

  • Versioned .txt files (intel-wifi-<version>.txt, intel-bt-<version>\_pid<PID>.txt) were being downloaded using Invoke-WebRequest with a cache-busting query parameter (?t=<timestamp>).
  • GitHub release asset URLs do not support query parameters — the appended cache buster caused the request to fail silently or return an HTML error page instead of the raw file content.
  • As a result, the parser found no SHA256 or Link fields and the driver was never installed, even though all versioned files were correctly present in the release assets.
  • This explains the previously observed symptom: updater correctly detects a new driver version and downloads the .cab, but does not install it.

🆕 What's New

• Dedicated Release Asset Download Function

  • New Get-ReleaseAssetContent function handles all versioned file downloads using System.Net.WebClient.DownloadString() — the same mechanism used for .md database files.
  • WebClient follows GitHub's redirects transparently (release assets redirect to objects.githubusercontent.com) and always returns raw text content.
  • A User-Agent: Mozilla/5.0 header is added to ensure consistent handling by GitHub's CDN.
  • No cache buster is appended — versioned release asset filenames already embed the version number, making them immutable by design.

• Removed Monolithic Fallback

  • intel-wifi-drivers-download.txt and intel-bt-drivers-download.txt are no longer read, parsed, or required.
  • The variables $wifiDownloadUrl and $btDownloadUrl have been removed from the configuration block.
  • Both files have been removed from the repository data/ folder. The updater's auto-update mechanism ensures all users run a version that does not depend on them.

• Removed Unused Parsers

  • The following functions have been removed as they were only used by the now-removed monolithic fallback:

    • Parse-WiFiDownloadList
    • Parse-BTDownloadList
    • Get-WiFiBlockForDevice
    • Get-BTBlockForDevice

• Updated Error Messages

  • Error output no longer references the removed monolithic files.

  • When a versioned file cannot be found, the message now directs users to check the versioned release assets directly:

    • Wi‑Fi: intel-wifi-<version>.txt in the archive-wifi release
    • Bluetooth: intel-bt-<version>\_pid<PID>.txt in the archive-bt release
