Owners of laptops of the series IdeaPad 310 often encounter a situation where the wireless connection stops working immediately after reinstalling the operating system or updating Windows. Model 15ISK Built on Intel Skylake processors, its network adapter requires a specific software approach to ensure proper operation. A missing wireless network icon or the "Connected, no internet access" status could indicate either a software glitch or simply disabling the module using the physical keys.
In this article, we'll look at all the possible reasons why you might not have internet. You'll learn how to activate it correctly. Wireless LAN Using keyboard shortcuts, check the status of services in the operating system and find the latest drivers for your laptop model. It is important to understand, that without a properly installed driver, even working hardware will not be able to function in the Windows 10 or 8.1 environment.
Before tackling complex settings, it's important to eliminate simple mechanical locks. Users often accidentally disable the module when trying to adjust the volume or screen brightness. Restoring communication In 80% of cases it takes no more than two minutes if you know exactly which button to press.
Physical activation and Fn key combination
On the laptop case Lenovo IdeaPad 310 15ISK A separate physical switch for wireless modules is rare. The primary control tool is the function key on the keyboard. You need to locate the F1-F12 key row and look for an icon resembling an antenna or airplane. On this model, this is most often the key F7 or F5, depending on the regional layout.
To activate airplane mode or turn on WiFi, use a combination. Press and hold the key Fn, located in the bottom row on the left, and without releasing it, press the corresponding function key. If the indicator on the screen does not respond, try pressing the key once without holding it down. Fn — in some BIOS versions, the priority of the function keys may be changed.
⚠️ Attention: If the airplane icon appears on the screen when you press the combination but it doesn't disappear, this could indicate an ACPI driver conflict or a frozen keyboard controller. In this case, simply restarting the laptop often solves the problem.
Sometimes the system requires time to initialize the hardware after waking up from sleep mode. If the WiFi indicator light (usually located near the power button or on the edge of the case) is orange or off, the module has been software-disabled. A green or white indicator light indicates radio module receives power and is ready to search for networks.
Checking adapter status in Windows
After confirming physical activation, you need to ensure that the operating system sees the network hardware. In Windows 10 and 8.1, network interfaces are managed through the Control Panel or the new system settings. Go to Settings → Network and Internet → Wi-Fi. A switch should be displayed here that switches the module to the "On" state.
A more in-depth check is performed through the classic network connections menu. Press the combination Win + R and enter the command ncpa.cplAll network adapters will be displayed in the window that opens. Find the device labeled "Wireless Network Connection." If the adapter's icon is gray and labeled "Disabled," right-click it and select "Enable."
The absence of a wireless adapter icon in the list of connections is a worrying sign. This indicates that Windows cannot identify the device. A malfunction may be the cause. Device Manager or a complete lack of a driver. In this case, the list will only show "Ethernet" (wired connection) and possibly an unknown device with a yellow exclamation mark.
It's also worth checking your power settings. The system may automatically disable the adapter to save power, after which it won't be able to use it correctly. In the adapter properties, on the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."
Installing and updating Wireless LAN drivers
The most common reason for WiFi not working on IdeaPad 310 15ISK - no driver. This model was equipped with various modules: from Realtek to Intel Dual Band WirelessThere is no universal driver, so you need to accurately determine the vendor of your hardware.
If you can connect your laptop to the internet via a LAN cable or your phone's USB modem, the easiest way is to use Device Manager. Right-click the "Start" button and select "Device Manager." Expand the "Network Adapters" tab. If you see a device with a yellow triangle or "Unknown Device," right-click it and select "Update Driver Software" → "Search Automatically."
However, automatic searches through Windows Update often fail to find Lenovo-specific drivers. In this case, you'll need a different computer with internet access. Visit Lenovo's official support page, enter your laptop's serial number (found on the sticker on the bottom of the case), and go to the "Drivers and Software" section. Find the "Networking: Wireless LAN" category and download the file corresponding to your version of Windows.
☑️ Driver installation algorithm
After installing the driver, be sure to reboot the system. Primary initialization The hardware error occurs at this point. If the problem persists after rebooting, try uninstalling the device from Device Manager (along with the software, if prompted) and rescanning the hardware configuration.
Diagnostics via Device Manager
Device Manager is the primary diagnostic tool. If there's no mention of Wireless or WLAN in the list of network adapters, check the "Video Adapters" and "Other Devices" sections. Sometimes a faulty driver can disguise itself as an unknown device. The error code in the device properties (Status tab) will point you in the right direction: code 10 or 43 indicates a hardware failure or resource conflict, while code 28 indicates a missing driver.
In some cases, resetting the BIOS settings helps. Enter the BIOS by pressing the key F2 or Fn+F2 when loading. Find the section Configuration or Security. Make sure that the item Wireless LAN or Onboard WLAN Device has status EnabledIf the device is disabled at the BIOS level, no actions in Windows will help.
| Error code | Description of the problem | Recommended action |
|---|---|---|
| Code 10 | The device cannot be started. | Reinstalling the driver, resetting the BIOS |
| Code 28 | Drivers not installed | Manual driver installation from the Lenovo website |
| Code 43 | Windows has stopped the device | Checking module contacts, replacing the WiFi card |
| Code 45 | The device is disabled | Connect the device (in the manager) |
If the Device Manager shows the device is working correctly, but no networks are found, the problem may lie in the WLAN AutoConfig service. Click Win + R, enter services.msc and find the service in the list WLAN AutoConfigMake sure the startup type is set to Automatic and the service is running.
⚠️ Attention: If the adapter keeps disappearing and reappearing in the Device Manager (making a USB connection sound), this may indicate a physical malfunction of the WiFi module or oxidation of the antenna contacts inside the case.
Resetting network settings and command line
If the driver is installed but the internet isn't working, it's possible that network protocol errors have accumulated in the system. Resetting the TCP/IP stack is an effective solution. Open the command prompt as administrator (search for "cmd" in the search bar, right-click → "Run as administrator").
Enter the following commands one by one, confirming each one by pressing Enter:
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
After running the last command, be sure to reboot your laptop. This process clears the DNS cache, resets Winsock socket settings, and refreshes IP addressing. For this model: IdeaPad 310 This is especially true after major Windows updates that may change system files.
What to do if resetting doesn't help?
If resetting the TCP/IP stack doesn't resolve the issue, try uninstalling any recently installed Windows updates. Microsoft patches sometimes conflict with Realtek drivers. It's also worth checking whether Airplane mode is enabled via the notification center (the message icon in the system tray).
There's also a built-in network troubleshooting tool. Right-click the network icon (even if it has an X) and select "Diagnose." The system will attempt to automatically find and fix any configuration or adapter reset errors.
Hardware problems and module replacement
If software methods are exhausted and WiFi is not working Lenovo 15ISK If it doesn't appear, it's likely a hardware issue. Laptops in this series have a removable WiFi module located under the bottom cover. Accessing it requires removing the back panel (usually just a few screws; sometimes, heat is required if the cover is latched).
The module is a small board connected to two thin wires (antennas): one black and one white. A common problem is loosening of the snap-on connectors. Gently press the antenna connectors until they click into place. You can also try removing the module itself (it's held in place at an angle by two screws), cleaning the contacts with an eraser, and reinserting it.
When purchasing a new module, pay attention to the form factor. IdeaPad 310 15ISK interface is used M.2 (NGFF) or, less commonly, Mini PCIe, depending on the motherboard revision. Popular compatible models include the Intel Dual Band Wireless-AC 3165 or similar Qualcomm Atheros cards. Make sure the card isn't blocked by the BIOS whitelist (although this is rare for Lenovo consumer laptops).
What driver is needed if the adapter model is unknown?
Download the HWInfo or AIDA64 utility. Launch it and find the "Network" section. The Vendor ID and Device ID will be listed there. Enter these codes into a search engine to accurately identify the chip manufacturer (Realtek, Intel, Broadcom) and download the correct driver.
Is it possible to use a USB WiFi adapter instead of the internal one?
Yes, this is a great temporary or permanent solution. Buy any USB WiFi adapter that supports your standard (preferably AC for speed). Windows 10 will often find a driver for it automatically. This will bypass the problem with a faulty built-in module.
Why is WiFi slow after turning it on?
Check your wireless frequency. The module may connect to the 2.4 GHz band instead of 5 GHz, which has more interference. Also, make sure that 802.11n/ac support is enabled in the adapter properties under "Advanced" in Device Manager and that roaming sensitivity is set to maximum speed.
The orange light is on, but it's not searching for a network. What should I do?
Orange usually indicates a software shutdown. In addition to the Fn keys, check that Airplane mode isn't enabled in the Windows Action Center. Also, check the BIOS and see if wireless devices are blocked there.
