A non-functional internal WiFi adapter in your laptop can disrupt your work, gaming, or online activities. However, there are multiple ways to restore internet connectivity, ranging from replacing the adapter to using external network devices. Here’s a detailed guide on the best solutions.
1. Replace with an Equivalent Internal WiFi Adapter
If you prefer keeping your laptop’s built-in WiFi functionality, replacing the faulty WiFi card with an equivalent one is a good option. Most laptops use M.2 or mini PCIe (mPCIe) WiFi cards, which can be replaced with some basic technical knowledge.
How to Check Your Laptop’s WiFi Adapter Type
For this you have to first identify your existing (dead) WiFi adapter card model. You can do this by opening the Device Manager on Windows or use System Information (Mac/Linux) to check your current WiFi adapter model. Then you can search this model online to determine if it is an M.2 or mPCIe card.
Alternatively, you can also physically examine your wireless network card. For this, you have to power off your laptop and remove its battery (if removable). Then unscrew the backpanel to find out the WiFi card slot.
- M.2 WiFi cards are small and have only 1 screw securing it. You should also notice the M.2 key design which can be of many types: A, E, A+E, M etc.
- mPCIe cards are a little bit larger and have 2 screws securing it.
Choosing the Right Replacement WiFi Adapter
If your laptop supports M.2, get an equivalent WiFi 6 or WiFi 7 adapter for better performance. If your laptop uses mPCIe, options are limited, but you can still find compatible WiFi 5/6 cards.
Pros:
✔ Restores built-in WiFi functionality.
✔ No need for external USB devices.
Cons:
✖ Requires opening the laptop (may void warranty).
✖ Some laptops have non-replaceable WiFi modules (e.g., soldered cards).
2. Upgrade to a WiFi 7 Adapter (with Bluetooth 5.4)
If your laptop supports M.2 WiFi cards, upgrading to a WiFi 7 adapter can significantly improve performance.
Benefits of Upgrading to WiFi 7
- Faster Speeds : WiFi 7 can exceed 30 Gbps, far surpassing WiFi 6.
- Lower Latency : Great for gaming and real-time applications.
- Improved Bluetooth : Get Bluetooth 5.4 for better wireless peripheral connectivity.
Recommended WiFi 7 Adapters:
- Intel BE200 : Supports WiFi 7 + Bluetooth 5.4 (See details)
- Killer AX1690 : Designed for high-speed gaming and networking.
Pros:
✔ Future-proof solution with WiFi 7 + Bluetooth 5.4.
✔ Better speeds and connectivity.
Cons:
✖ Requires a WiFi 7-compatible router for full benefits.
✖ Not all laptops support M.2 WiFi 7 cards.
3. Use a Nano USB WiFi Adapter (TP-Link, ASUS, etc.)
If replacing the internal adapter is not an option, a USB WiFi adapter is a simple and effective solution. These devices plug into your laptop’s USB port and provide wireless internet instantly.
Best Nano USB WiFi Adapters:
- TP-Link Archer T3U : Dual-band WiFi 5 adapter. (TP-Link Archer T3U)
- ASUS USB-AX56 : USB WiFi 6 adapter with better range.
- Edimax EW-7811Un : Budget-friendly option.
Pros:
✔ Quick plug-and-play solution.
✔ No need to open the laptop.
✔ Portable and compact.
Cons:
✖ May not be as fast as an internal adapter.
✖ Takes up a USB port.
4. Use a USB-C to Ethernet Adapter for Wired Connectivity
If you want a more stable and high-speed internet connection, a USB-C to Ethernet adapter is a great alternative. This method is ideal if your laptop lacks an Ethernet port.
Recommended USB-C to Ethernet Adapters:
- Anker USB-C to Ethernet Adapter (Supports 1 Gbps speeds).
- UGREEN USB-C to Ethernet Adapter – Reliable and widely compatible.
Pros:
✔ More reliable than WiFi (no interference issues).
✔ Faster 1 Gbps+ speeds (great for gaming and streaming).
✔ Works on most modern laptops with USB-C ports.
Cons:
✖ Requires a wired network connection.
✖ Less portable than a wireless solution.
5. Connect Directly via Ethernet Cable (if available)
If your laptop has a built-in Ethernet port, simply connect an Ethernet cable to your router or modem for uninterrupted, high-speed internet access.
How to Connect via Ethernet:
- Plug one end of the Ethernet cable into your laptop’s LAN port.
- Connect the other end to your router or modem.
- Your laptop should automatically recognize the wired connection.
Pros:
✔ Best speed and reliability.
✔ No additional devices required.
Cons:
✖ Not portable : you are tethered to a wired connection.
Conclusion
If your laptop’s internal WiFi adapter stops working, you have multiple solutions based on your needs. Choosing the right solution depends on whether you prioritize portability, speed, or ease of installation. If WiFi is essential, a WiFi 7 adapter or USB WiFi dongle is a great fix. If you need ultra-reliable internet, a wired connection is the best choice.
