This makes their network unreliable and, even worse, requires frequent reconnection to get going again. If you are also troubled by this issue, we will show you how to fix it and restore normal service in this guide.

Why is my Netgear WiFi adapter not working?

Several factors can cause the Netgear WiFi adapter to stop working. Below are some of the notable ones:

Faulty or incompatible drivers: If your Netgear A6100 is not detecting networks, it might be due to incompatible or outdated drivers. You need to update your driver from the official source to fix this. Wrong power settings: Sometimes, your Netgear WiFi adapter disconnects because your PC needs to save power. The solution is to disable any power-saving feature that can cause your adapter to stop working.

What can I do if the Netgear WiFi adapter is not working?

1. Download and install the latest Netgear drivers

In most cases, the Netgear N300 wireless WiFi USB adapter WNA3100 stops working because of generic drivers installed by Windows update. You must install the latest drivers from the Netgear website to fix this. Alternatively, you can use the DriverFix tool to update your drivers to avoid permanently damaging your computer by manually downloading the wrong driver versions. This incredible program looks for new hardware drivers and automatically downloads updates. It scans your system and lists all existing and possibly missing drivers. The tool also detects if there is already a new version for current records. If necessary, these can be updated directly via DriverFix. ⇒ Get DriverFix

2. Change power settings

2.1. Disable USB selective suspend

One of the power management features of your PC is the ability to suspend your USB settings. Unfortunately, this can cause the Netgear WiFi adapter to stop working. Disabling the feature should help restore normalcy.

2.2. Disable USB root hub power preserving

Another power-saving option that can cause the Netgear WiFi adapter to stop working is the ability to turn off your USB hubs. Unfortunately, this can cause any device connected to the USB port to stop working temporarily.

2.3. Disable WLAN adapter suspend

Various power settings commonly hidden within the system are vital for the performance of the Netgear adapter. Some of these are related to USB power reduction, while others are there to tend to wireless adapters. Both of these are valuable if you want to preserve the battery life. The power-related settings are enabled by default, and what we need to do is to disable them.

3. Change channel settings

For the best overall WiFi performance, we advise you to stick to 20 MHz of channel width and channels 1, 6, or 11. This is because those are rarely crowded by non-Wi-Fi devices that use similar frequencies. After doing this, check if the Netgear WiFi adapter is now working.

4. Check the equipment

Make sure that everything is working as intended hardware-wise. For example, try multiple USB ports and use the Netgear adapter on a different computer. If everything works as it should, the problem lies in your PC rather than the Netgear adapter. That should point you toward the other solutions we provided in this article. Note that it’s essential to know that USB 3.0 works properly on the 5 GHz bands. For 2.4 GHz, make sure to stick with USB 2.0.

5. Uninstall network adapter drivers

If you still can’t get your Netgear WiFi adapter to work, you might need to uninstall and reinstall the driver. Aside from scanning for hardware changes, you can install the latest drivers from the official website.

6. Disable the Block Internet Connection Sharing option

Antivirus software comes with a Firewall, and sometimes it can cause problems, so you might want to turn it off. For example, Bitdefender has the Block Internet Connection Sharing option in its advanced settings, so to resolve this issue, it’s highly recommended that you turn it off. That’s about it. You should now be able to fix the Netgear WiFi adapter not working issue with the solutions in this guide. If no USB WiFi adapter works on your PC, check our detailed guide to fix it quickly.
