Easy Ways to Fix Common WiFi Adapter Problems

If you’re wondering why your phone doesn’t have an internet connection but the other devices remain connected, then there might be a problem with your WiFi adapter that needs to be fixed. Common WiFi problems like dropping connection, slower speeds, or your device just won’t connect to the network at all can be caused by your WiFi adapter.

A WiFi adapter is a device used for connecting your computer to wireless networks. The common problem with WiFi adapters is detection failures. Fortunately, most problems are easy to fix.

This guide provides solutions to common Wi-Fi adapter problems so you can get back online quickly.

What Is A WiFi Adapter?

A WiFi adapter allows a computer or other device to connect to a wireless network for internet access. WiFi adapters can be incorporated inside laptops and smartphones or external, such as USB adapters or PCIe cards for desktops. Your device can stream content, connect to the internet, and communicate with other wireless network devices using these adapters.

Problem #1: Wi-Fi Adapter Not Detected

Your computer may not detect the WiFi adapter, which can occur due to driver issues, hardware problems, or incorrect settings.

Solution

If you're using an external USB Wi-Fi adapter, ensure it's securely connected to the USB port. Try unplugging and replugging the adapter into a different USB port. If you’re using an internal adapter, ensure it's correctly seated in its slot on the motherboard.
Press Win + X and select Device Manager. Look for your WiFi adapter under Network Adapters. If it’s not listed, or if it has a yellow exclamation mark, there’s likely a driver issue.
Right-click on the Wi-Fi adapter in Device Manager and select Update driver. Choose Search automatically for updated driver software. If no update is found, visit the adapter manufacturer's website to download and install the latest driver manually.
If updating the driver doesn’t work, uninstall the adapter by right-clicking on it in Device Manager and selecting Uninstall device. Restart your computer, and Windows should automatically reinstall the adapter.

Problem #2: Intermittent Connection Drops

Your Wi-Fi connection might drop intermittently and cause disruptions, especially when streaming or downloading.

Solution

Wi-Fi signals can be disrupted by other electronic devices like microwaves, cordless phones, or even neighboring Wi-Fi networks. Try moving your computer or router to reduce interference. Ideally, place the router in a central location, away from potential sources of interference.
If multiple Wi-Fi networks are operating on the same channel in your area, it can cause congestion. Log into your router’s settings and change the Wi-Fi channel to one with less interference. Use a Wi-Fi analyzer tool to find the least congested channel.
On Windows, go to Device Manager, right-click on your Wi-Fi adapter, and select Properties. Under the Power Management tab, uncheck Allow the computer to turn off this device to save power. This prevents your computer from automatically disabling the WiFi adapter to conserve energy, which can cause connection drops.
Ensure your router's firmware is up to date by visiting the manufacturer’s website. Firmware updates can improve stability and performance, potentially resolving connection drop issues.

Problem #3: Slow Wi-Fi Speeds

Slow Wi-Fi speeds can result from outdated drivers, poor signal strength, or incorrect settings.

Solution

Make sure that your computer is within range of the WiFi router. If possible, move closer to the router to improve signal strength. Avoid placing the router in corners, behind furniture, or near large metal objects, which can block the signal.
Outdated drivers can significantly impact your Wi-Fi speed. Follow the steps mentioned earlier to update your drivers.
Log into your router’s settings and switch to the 5 GHz band if supported. The 5 GHz band offers faster speeds and is less crowded than the 2.4 GHz band, though it has a shorter range. Eenable Quality of Service (QoS) settings to prioritize bandwidth for devices or applications that require more speed, such as video streaming or online gaming.
If your Wi-Fi signal is weak due to distance from the router, consider using a Wi-Fi extender or mesh network system to boost the signal. These devices can help eliminate dead zones in your home or office and provide more consistent speeds throughout the area.

Problem #4: Wi-Fi Adapter Keeps Disconnecting

If your Wi-Fi adapter keeps disconnecting from the network, it could be due to power settings, driver issues, or interference.

Solution

Go to Control Panel > Power Options and select High Performance. Click on Change Plan Settings and then Change Advanced Power Settings. Find Wireless Adapter Settings and set it to Maximum Performance.
In Device Manager, right-click your Wi-Fi adapter, choose Properties, and adjust settings like Roaming Aggressiveness or Preferred Band under the Advanced tab.
Check for interference from other devices and ensure there’s minimal disruption to the Wi-Fi signal.
Reset your router to refresh the connection and potentially solve the issue.

Problem #5: Wi-Fi Adapter Not Connecting to a Network

Your WiFi adapter may not connect to a network due to incorrect settings, driver issues, or network configuration problems.

Solution

Go to your network settings, find the problematic network, and select Forget. Then reconnect to the network by entering the password again.
Ensure the security settings on your router match those on your Wi-Fi adapter. For instance, if your router uses WPA3, but your adapter only supports WPA2, it won’t connect.
Update your Wi-Fi adapter drivers as mentioned earlier.
Log into your router and check the network settings. Ensure the SSID (network name) is broadcast and that the network mode (e.g., 802.11ac) is compatible with your Wi-Fi adapter.
Check if your computer is set to obtain an IP address automatically unless specific network settings are needed.

Problem #6: Wi-Fi Adapter Not Working After a Windows Update

After a Windows update, your WiFi adapter may stop working due to compatibility issues with the adapter’s driver.

Solution

Go to Device Manager, right-click your Wi-Fi adapter, and select Properties. Under the Driver tab, click Roll Back Driver to revert to the previous version.
Uninstall the adapter as described earlier, restart your computer, and let Windows reinstall the driver.
Visit the manufacturer’s website to check if there is a new driver compatible with the latest Windows update.
If all else fails, use System Restore to revert your system to a point before the problematic update.

Takeaway

Wi-Fi adapter problems can be frustrating, but most issues are easy to fix. Whether your adapter isn’t being detected, keeps disconnecting, or is experiencing slow speeds, these solutions should help you resolve the issues.

TP-Link offers a range of WiFi adapters designed to enhance your internet connectivity and prevent slow speeds. When you upgrade to a TP-Link WiFi adapter, you can improve your connection stability and speed and enjoy a smoother online experience. With these adapters, you can build a reliable internet system, reduce interruptions and get more consistent performance for your home or office.

FAQs on WiFi Adapter

1. Do I need a WiFi adapter if my device already has built-in WiFi?

If your device has built-in WiFi, you don't need a separate WiFi adapter, but if the built-in WiFi is outdated or not working properly, an external WiFi adapter helps improve your connection.

2. What should I look for when buying a WiFi adapter?

Consider compatibility with your device, support for the latest WiFi standards (WiFi 5 or WiFi 6), the speed ratings, and whether you need a USB or PCIe adapter.

3. Can I use a WiFi adapter on a gaming console?

Many gaming consoles support WiFi adapters, especially if their built-in WiFi is weak or outdated. But make sure to check the console’s specifications because not all WiFi adapters are compatible.

4. Can a WiFi adapter be used on multiple devices?

A USB WiFi adapter can be used on multiple devices, but only one at a time. PCIe adapters are installed inside a computer and are not easily transferable between devices.
