Step 2: Download the driver

If the adapter is detected, download the driver from the official website. Lenovo or chip manufacturer:

• 🔗 Lenovo official website (enter your laptop model) G580)
• 🔗 Intel website (if the adapter is from Intel)
• 🔗 Broadcom website (for Broadcom adapters)

⚠️ Attention: If in Device Manager the adapter is marked with a yellow exclamation mark or is missing altogether, try delete it (right click → Remove device), then press Update hardware configuration (magnifying glass icon at the top). Sometimes this helps the system automatically find the driver.

Critical Information: On Laptops Lenovo G580 with adapters Broadcom 4313 Compatibility issues with Windows 10/11 often occur. In this case, it is recommended to manually install the driver version 6.30.223.271 (available on the Broadcom website in archive).

Updating the BIOS is a risky procedure. If you're unsure about what you're doing, it's best to contact a service center.

5. Diagnosing problems connecting to the router

If Wi-Fi is on, the drivers are installed, but Lenovo G580 doesn't see the network or does not connect to the router, the problem may be in the network settings itself. Check the following:

• 📶 The router is turned on and distributing Wi-Fi: Make sure the wireless indicator on your router is lit. Try connecting to the network from another device (phone, tablet).
• 🔒 Correct password: Please enter your Wi-Fi password carefully, paying attention to case and special characters. If you have forgotten your password, reset it through your router settings (usually at 192.168.1.1 or 192.168.0.1).
• 📡 Router operating mode: Make sure your router is in wireless mode. 802.11n or 802.11ac (and not only 802.11b/g). Old adapters Lenovo G580 may not support modern standards Wi-Fi 6.
• 🔄 Channel and frequency: If the router operates at a frequency 5 GHz, try switching to 2.4 GHz (in the router settings). Many adapters G580 support only 2.4 GHz.

Also check IP settings:

1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Right click on Wi-Fi and select Properties.
3. Find Internet Protocol version 4 (TCP/IPv4) and click Properties.
4. Make sure it is selected Obtain an IP address automatically And Obtain DNS server address automatically.

6. Hardware malfunctions: when to take it to a service center

If all the above methods do not help, the problem may be in hardwareHere are the signs that repairs are needed:

• 🔌 The adapter is not detected in Device Manager: even after installing the drivers.
• 💥 The laptop does not respond to the Wi-Fi enable keys: no indicator, no notifications.
• 🔥 Damage to the housing or connectors: for example, after a fall or liquid spill.
• 📉 Wi-Fi is unstable: It keeps breaking down, even if the router is fine.

The most common hardware problems Lenovo G580:

1. Detached antennas: The wireless adapter is connected to the motherboard by two thin wires (antennas). If these are loose or damaged, the signal will be weak or absent.
2. Adapter failure: Most often, this occurs due to overheating or power surges. The solution is to replace it with a new one (for example, Intel 7260 or TP-Link TL-WN725N).
3. Motherboard problems: If other devices (USB, sound) do not work, this may indicate a faulty south bridge.

⚠️ Attention: If you're inexperienced in disassembling laptops, don't attempt to check the antennas or adapter yourself. Contact a service center—repairs will be cheaper than replacing damaged parts.

7. Alternative ways to connect to the Internet

If Wi-Fi is on Lenovo G580 If it still doesn't work, you can use alternative methods to connect to the Internet:

• 🌐 Ethernet cable: Connect your laptop to the router via LAN port (RJ-45 connector). This is the most stable method, but requires a wire.
• 📱 USB modem: Buy a 4G/5G modem (for example, Huawei E3372) and connect it to a USB port. Many operators (MTS, Beeline, Tele2) sell modems with unlimited data plans.
• 📲 Distribution from a phone: Turn it on on your smartphone modem mode and connect the laptop via USB or Wi-Fi (if the adapter works at all).
• 🖥️ External Wi-Fi adapter: Purchase a USB adapter (eg. TP-Link TL-WN725N (for ~500 rubles). It plugs into a USB port and replaces the built-in Wi-Fi.

If you are temporarily using an alternative method, but want to restore the functionality of the built-in Wi-Fi, we recommend that you perform full diagnostics:

1. Test the laptop on a different operating system (for example, with a Linux LiveCD).
2. Check your Wi-Fi connection Safe mode (press when loading F8).
3. Update BIOS to the latest version (careful!).
