If you are the one who is experiencing connectivity issues with the BrosTrend AC1200 driver like frequent disconnections, slow speeds or failure to connect. This guide provides some of the troubleshooting tips, highlights what typically works and outlines methods to restore stable performance.

Confirm Source of Issue

Before you start making changes into the AC1200 driver setup, make sure to check your internet on another device. The device can be phone or laptop whatever just something which is not using the adapter. If everything else is slow or dead then there is an ISP issue and not a driver problem.

If the other devices are working properly but your AC1200 connection is bad, keep reading.

Uninstall and Reinstall the Driver

A fresh install of driver can fix number of errors.

Here is how to do it:

1. Make sure to visit the Device Manager (hit Windows key, type “Device Manager”).
2. Open the list of Network Adapters and right click on the Brostrend device.
3. After that hit uninstall device.
4. You have to select the “Delete the driver software for this device” box and this is essential.  
5. Make sure to remove the plug of an adapter.
6. Restart your PC.
7. Plug the adapter back in and either allow the Windows to install the default driver or run the setup from BrosTrend’s official site.

Tip: Do not use any random driver from a third-party site. Always get the latest BrosTrend AC1200 driver from their official download page.

Switch USB Ports

The front-panel USB port on the desktop supplies insufficient power to the adapter. Relocate it to a USB 3.0 port which is directly connected to the motherboard for better stability. It is also suggested to avoid using USB hubs, as a direct connection ensures better performance for these adapters.

Reset Network Settings

Sometimes the driver itself is works properly but Windows’ network configuration creates issue.  Use of the Command Prompt (admin mode) can reset the network settings and clear unnecessary data.

ipconfig /flushdns

Restart after the use of these particular commands. The AC1200 driver works effectively after this.

Disable Power Saving Mode

Sometimes, windows may automatically turn off some of the devices to conserve power which can include the Wi-Fi adapter.
To avoid this, go to Device Manager, right-click the BrosTrend adapter, select Properties → Power Management and uncheck the option “Allow the computer to turn off this device to save power.”
This adjustment can help to reduce unexpected disconnections. 

Change the Wireless Mode

TheAC1200 adapter sometimes struggles when your router is set to certain modes. Make sure to

Go into Device Manager → BrosTrend adapter → Properties → Advanced tab.

Look for the settings like:

• Wireless Mode
• Preferred Band
• Channel Width

Reinstall from the BrosTrend CD

CD is used as sometimes the latest driver is not the most stable for your specific device. You have to reinstall from the CD, then update manually by the help of Device Manager instead of using the auto-installer. This will give your balance between speed and stability.

Disable Conflicting Network Devices

If you have other Wi-Fi adapters or even old VPN network drivers then they can mess with the BrosTrend AC1200 driver. You should disable any unused adapters. There will be less confusion for Windows.

Check Your Router’s Settings

The adapter is not always faulty. Log into your router and check:

• The firmware is updated or not.
• The channel should not be overcrowded.
• MAC filtering is not blocking your device.

Make sure that your “Smart Connect” is enabled, which keep switching between between bands. As disabling that can stop the constant reconnecting.

Clean Windows Install (The Last Resort)

If you have tried everything and still your wifi is creating an issue then the problem is that your window is just too messed up to fix easily. Reinstall, setup software fresh and the BrosTrend AC1200 driver works smoothly.

Final Thoughts

The AC1200 adapter is not bad when it is working in a right and it is powerful. USB Wi-Fi adapters can be a bit tricky and the BrosTrend AC1200 driver might have problems if you use a faulty USB port, have power-saving turned on or run into Windows network issues. Make sure:

·         Uninstall → reinstall from the official site.

• Use a USB 3.0 port directly on the motherboard.
