Da Net Booster is a free, open-source PdaNet alternative that shares your Android phone's mobile data (4G / 5G) with your Windows PC over a USB cable. It was built to fix the high ping, jitter and packet loss you get when gaming on a phone hotspot (tested with Valorant on Jio 5G). It also shows you, live, whether the lag comes from your connection or from the mobile tower.

No root. No USB debugging. No subscription. One installer for the PC, one app for the phone.

Why not just use the phone's hotspot?

	Phone Wi-Fi hotspot	Da Net Booster (USB)
Link to the PC	Wi-Fi radio: interference, power saving, scanning	USB cable: steady, no radio in between
Extra delay added	Varies, spikes are common	~2–3 ms (measured, see below)
Tells you why it lags	No	Yes: live ping, jitter, loss and signal, and whether the problem is the tower or your link

1. The PC app creates a virtual network adapter and routes all of the PC's traffic (TCP and UDP, so games and voice chat too) into it.
2. The tunnel carries that traffic over the USB cable. Android's USB tethering is used purely as the cable; nothing is shared through the phone's hotspot.
3. The phone app receives it and opens the real connections itself, over your mobile data. To the network, it is ordinary traffic from the phone.
4. Replies come back the same way. A small probe measures ping, jitter and loss every half second, so the dashboard shows exactly how your connection is doing.

Measured, not guessed

Logged during real Valorant sessions on one phone (vivo, Jio 5G SA, India). The PC measured through the tunnel while the phone measured directly, at the same moment:

Session	Through Da Net Booster	Phone alone (no PC)	Cost of the tunnel
Match, 8:15 pm	27 ms median · 43 ms p95 · 0% loss	25 ms · 37 ms · 0%	~2 ms
23 min, 10:04 pm	32 ms · 80 ms p95 · 0.4% loss	29 ms · 77 ms · 0%	~3 ms

The late-night spikes appeared on both sides at once. That is tower congestion, not the app, and the dashboard lets you tell the difference. Download speed over the USB link: ~2.8 MB/s, limited by the mobile network rather than by the cable.

Get started

1. PC: download and run DaNetBooster-win-Setup.exe. It installs the app, a desktop shortcut and .NET if needed. _{Windows may say "Windows protected your PC": click More info → Run anyway (the app isn't code-signed yet). The first time you press Connect, Windows asks once to install a small helper service that creates the network adapter; after that the app runs without admin rights.}
2. Phone: in the PC app click Get phone app and scan the QR code, or download the APK directly. Allow the install when Android asks.
3. Plug the phone in with USB and turn on USB tethering. The phone app has a Turn on button that takes you there.
4. Tap Start sharing on the phone, then Connect on the PC. Done.

  

Features

• 🎮 Gaming-first dashboard: steady ping (median of the last 5 s), jitter, packet loss, a 2-minute ping graph with lag zones, and a plain-language verdict ("Stable · good for competitive play").
• 🟢 Status you can read from across the room: on Windows 11 the window border and taskbar icon turn green, amber or red.
• 📶 Phone signal at a glance: 4G/5G, signal strength and quality, a warning if the phone is on Wi-Fi, and a peak-hours hint.
• 🔌 All traffic, not just the browser: TCP and UDP, so games, Discord voice and DNS go through too.
• 🛡️ Match-safe: disconnect asks first, and updates only install when you're disconnected or closing the app.
• 🔄 Automatic updates for both apps from GitHub Releases.
• 🛡️ No admin app: the window runs as a normal user. A tiny helper service in Program Files does only the admin work (network adapter and routes), and it will only ever tunnel to the phone it sees on USB tethering.
• 🔒 Private: the phone only accepts connections from the PC on the USB link, never from Wi-Fi or the mobile network. No accounts, no telemetry (the only outside request is the update check to GitHub).

FAQ

How do I share my phone's internet with my PC over USB without a hotspot? Install both apps, turn on USB tethering, tap Start sharing, then click Connect. The PC's traffic goes over the cable to the phone, and the phone sends it out over mobile data.

How can I reduce ping and packet loss on mobile data for Valorant (or CS2, Apex, Fortnite)? Use a cable instead of a hotspot: it removes the Wi-Fi hop, which is a common source of spikes. Then watch the graph. If spikes show up together with falling signal, move the phone (near a window, higher up). If the signal stays strong and ping still spikes in the evening, the tower is congested: try 4G-only vs 5G, or your other SIM.

Is this like PdaNet+, EasyTether or FoxFi? Same idea (PC internet through the phone over USB, no root), but free and open source, with a live latency dashboard built for games. It is not affiliated with PdaNet, June Fabrics, EasyTether or FoxFi.

Do I need USB debugging or root? No. USB debugging is only used by developers as a fallback link.

Does it work on Mac or Linux? Not yet: the PC app is Windows 10/11 only.

Will my carrier see this as tethering? The phone opens every connection itself, so the traffic looks like the phone's own. Your mobile plan's terms still apply, so check them.

Build from source

For developers

• Phone app: android/ (Kotlin, plain Android Views, no dependencies). cd android && ./gradlew assembleDebug
• PC app: desktop/DaNetBooster/ (.NET 8 WinForms). Run scripts/fetch-tools.ps1 once to download adb and hev-socks5-tunnel, then dotnet build.
• Releases: push a tag like v1.4.0. .github/workflows/release.yml tests and builds both apps, signs the APK and publishes the installer and APK to GitHub Releases, and installed apps pick up the update from there.
