Security: How to Protect Your Network from Hacking

Sharing Wi-Fi from a laptop is convenient, but it's fraught with risks. If you don't set up security, your network can be used by neighbors or even hackers to attack other devices.

Basic safety rules:

• 🔐 Use complex password (minimum 12 characters, with mixed-case letters, numbers, and special characters). Example: WiFi@Home_2026!K.
• 🔄 Change your password every 1–2 months (especially if strangers have connected to the network).
• 🛡️ Turn off the network when it is not needed (using the command netsh wlan stop hostednetwork).
• 📋 Keep a log of connected devices (in MyPublicWiFi or through arp -a (in the command line).

Additional measures:

• 🔒 Turn it off WPS (if your adapter supports it) - this protocol is vulnerable to brute force attacks.
• 🌐 Set up MAC address filtering (in programs like Connectify).
• 🔄 Regularly check for unknown devices on the network using the command:

arp -a

If you see unfamiliar IP-addresses - change password.

What to do if your network has already been hacked?

• 🚨 Disable Wi-Fi sharing immediately.
• 🔑 Change your password to a more complex one.
• 🛡️ Check your laptop for viruses (for example, Malwarebytes or Dr.Web CureIt!).
• 🔄 If you suspect an attacker has accessed your files, change the passwords for important services.

Optimizing connection speed and stability

If your network is working but your speed is slow, try these tips:

1. Selecting the optimal Wi-Fi channel

By default Windows Selects a channel automatically, but it may be congested by neighboring networks. How to find a free channel:

• 📡 Use utilities like WiFi Analyzer (For Android) or inSSIDer (For Windows).
• 🔄 Choose a channel with minimal load (usually 1, 6 or 11 For 2.4 GHz).
• 📶 For 5 GHz (if supported) select channels 36, 40, 44 or 48.

2. Configuring traffic priority (QoS)

If you share your internet connection with multiple devices, you can limit bandwidth-hungry apps (such as torrents or online games):

• 🖥️ Open Control Panel → System and Security → Administrative Tools → Local Security Policy.
• 🔄 Go to QoS policies and create a new rule to limit the speed.

3. Disable background traffic

Services Windows and programs can "eat up" bandwidth. To free up resources:

• 🔧 Disable automatic updates Windows (temporarily): Control Panel → Windows Update → Change settings → Important updates → Don't check for updates.
• 📥 Pause downloads in Torrent, Steam, Origin and other managers.
• 🔄 Close background processes via Task Manager (especially Svchost.exe, consuming the network).

4. Using an external antenna (for weak signal)

If devices only connect near the laptop, the problem may be a weak signal. Solutions:

• 📡 Buy USB Wi-Fi adapter with an external antenna (for example, TP-Link TL-WN722N).
• 🔋 Check if power saving mode is enabled for your Wi-Fi adapter.
• 📶 Change the location of your laptop—walls and metal objects weaken the signal.

Alternative ways to distribute Internet

If Wi-Fi sharing isn't working or you need to connect a device without wireless support (such as an old printer), consider these alternatives:

1. Sharing via Bluetooth

Suitable for connecting 1-2 devices over a short distance (up to 10 meters). How to set it up:

• 🔵 Turn on Bluetooth on the laptop and the target device.
• 🖱️ Go to Settings → Devices → Bluetooth.
• 🔄 Click Add a device and select Bluetooth.
• 📋 After pairing in Control Panel → Network → Change adapter settings find Bluetooth connection, right click and select Properties → Access.

Suitable for desktop PCs or devices without Wi-Fi. Required crossover cable or regular Ethernet-cable + hub.

• 🔌 Connect the cable to the second port on the laptop (if available).
• 🖥️ Go to Network and Sharing Center → Change adapter settings.
• 🔄 Right-click on the main connection (for example, Ethernet) → Properties → Access.
• ✅ Allow sharing and select Ethernet 2 (or Local Area Connection 2).

3. Using a laptop as a repeater

If you already have a Wi-Fi network, but the signal is weak in some areas, you can turn your laptop into a signal amplifier:

• 📡 Connect to the main Wi-Fi network.
• 🔄 Create a new network via command line (cm. Method 1).
• 🔗 In the shared network settings, specify the primary Wi-Fi connection as the internet source.

⚠️ Attention: When distributing through Bluetooth or Ethernet the speed will be limited by the interface bandwidth. For example, Bluetooth 4.0 gives the maximum 25 Mbps, A Ethernet 100 Mbps — to 100 Mbps (but the actual speed is lower due to overhead).
