What should I do if the Mercusys network adapter is not working properly in my computer?

Please note: If your laptop has built-in WiFi but you add a new adapter that connects through the PC Card adapter or a USB port, you will need to remove or disable Windows drivers for the original unit. Please refer here to disable the original adapter.

Case 1 Slow speed

Step 1. Check Wi-Fi signal strength. If signal is weak, move the computer closer to your router if possible.(About 10-15 feet)

Step 2. Check whether the problem happens on 2.4GHz or 5GHz if it’s a dual-band adapter.

Step 3. Contact the router support to change channel and channel width on your router to avoid possible interference.

Step 4. Update driver of the adapter (skip if you don’t know how to do that).

Step 5. Please check the link speed (FAQ767) of the wireless adapter is normal or not. If you can get the normal link speed. Normally, we can get 30-50% of the link speed.

Step 6. Please use your computer test speed again. Then use your phone/iPad to connect to your host Wi-Fi and test speed in the same location. If the result is higher than your computer’s speed, please contact Mercusys support with the results above and tell us the operating system of your computer.
