Is the adapter compatible with Mac OS or Linux?

No, according to the manual, the adapter is designed only for Windows. No official drivers are provided for Mac or Linux. Its use is limited to Windows XP/Vista/7/8/8.1 systems.

How to configure Wi-Fi using the WPS button?

Press the WPS button on your router, then within 2 minutes, press the WPS button on the adapter (or via software). The connection is made automatically without a password. Check that your router supports WPS.

What is the maximum range of the adapter?

Range depends on the environment (walls, interference). In open area, the 2.4 GHz signal can reach several tens of meters. Data rate decreases with distance. For best performance, stay in the same room as the router.

Why is my data rate lower than advertised?

Theoretical speeds (300 Mbit/s) are achieved under ideal conditions. In practice, actual speed is reduced by obstacles, interference, distance, and number of connected devices. Use the least crowded Wi-Fi channel.

Is it normal for the adapter to heat up?

Yes, slight warmth during use is normal. If the adapter becomes very hot to the touch, unplug it and check that it is not obstructed. Avoid leaving it in direct sunlight or near a heat source.

Can I use the adapter on a USB extension cable?

Yes, it is possible to use a USB extension cable to improve antenna positioning. Use a good quality cable (no more than 5 meters) to avoid signal loss.

How to fix intermittent connection issues?

Try the following solutions: 1) Unplug and replug the adapter. 2) Reinstall the driver. 3) Change the USB port (prefer a USB 2.0 port). 4) Update your motherboard driver. 5) Keep the adapter away from sources of interference (microwaves, cordless phones).
