🔍 Overview: Why Windows Network Throttles Your Connection

Out of the box, Windows 10 and 11 prioritize battery preservation and legacy compatibility over maximum network throughput:

1. Sticky 2.4 GHz Band: Laptops frequently stay trapped on slow, congested 2.4 GHz Wi-Fi channels (18–30 Mbps) even when clean 5 GHz Wi-Fi 6 (400–1000+ Mbps) is broadcast from the exact same access point.
2. Antenna Sleep Modes (Auto SMPS): Wireless cards constantly put spatial antennas to sleep to save milliwatts of power, causing packet micro-stutters and jitter.
3. Slow ISP DNS Lookups: Default router/ISP DNS servers often take 200–1200 ms per domain resolution, causing web pages and applications to feel sluggish.
4. Windows Network Throttling Index: Windows limits non-multimedia network processing to 10 packets per millisecond by default.
5. Background P2P Upload Leeching: Windows Delivery Optimization uploads update packages to external internet peers, saturating upload bandwidth.

NetMan solves all of these issues in one lightweight, transparent, open-source tool.

📊 Why NetMan Works: The Engineering Behind the Speedup

When testing NetMan on an Intel Wi-Fi 6E AX211 card connected to an enterprise campus network (KPR Institutions):

BEFORE OPTIMIZATION:
- Band: 2.4 GHz (Channel 11) | Channel Load: 55%
- Physical Link Speed: 18 – 26 Mbps
- DNS Resolution Latency: 1,173 ms
- Ping Latency: 227 ms

AFTER NETMAN TURBO BOOST:
- Band: 5 GHz Wi-Fi 6 (Channel 120) | Channel Load: 10%
- Physical Link Speed: 516 Mbps (20x Faster!)
- DNS Resolution Latency: 17.8 ms (65x Faster!)
- Ping Latency: 12 – 15 ms (15x Lower Latency!)

❓ Frequently Asked Questions (FAQ)

Does NetMan affect the internet speed of people around me?

No. In fact, it helps them! By moving your high-bandwidth laptop from the congested 2.4 GHz band to the spacious 5 GHz band, you free up airtime and wireless spectrum for other nearby devices.

Is NetMan safe and reversible?

Yes. NetMan creates a complete JSON snapshot of your original adapter properties and network configuration before applying changes. You can revert everything back to Windows defaults with 1 click in the "Backup & Restore" tab.

Do I need to run NetMan every time I boot my PC?

No. The Wi-Fi adapter hardware properties and TCP/IP stack configurations are saved in the Windows hardware registry and persist across reboots, sleep cycles, and network reconnects.

Does NetMan work on all Wi-Fi cards?

Yes. Wi-Fi band locking, Throughput Booster, and MIMO controls work across Intel (Wi-Fi 5, 6, 6E, 7), Realtek, MediaTek, and Qualcomm wireless adapters. DNS benchmarking and TCP stack tuning work on all Windows 10 and 11 network adapters (both Wi-Fi and Ethernet).
