5. Кыйынчылыктарды
5.1 Adapter Not Detected / No Wi-Fi Connection
- USB портун текшерүү: Ensure the adapter is firmly plugged into a functioning USB port. Try a different USB port, preferably a USB 3.0 port if available.
- Драйверди орнотуу: For Windows, allow a few minutes for the built-in driver to install automatically. For Mac/Linux, ensure you have downloaded and installed the correct drivers from the COMFAST webсайт.
- Компьютерди кайра иштетүү: Жөнөкөй кайра күйгүзүү көбүнчө аныктоо маселелерин чечет.
- Аппарат менеджери: In Windows Device Manager, check if the adapter is listed under 'Network adapters' without any error symbols. If there are errors, try updating or reinstalling the driver.
5.2 Байланыш ылдамдыгынын жайлашы
- Антеннаны тууралоо: Adjust the position of the dual antennas to optimize signal reception.
- Жыштык тилкеси: If you are close to your router, try connecting to the 5.8GHz band for faster speeds. If you are further away or have many obstacles, the 2.4GHz band might offer a more stable connection, albeit slower.
- USB 3.0 порт: Ensure the adapter is connected to a USB 3.0 port for maximum speed. USB 2.0 ports will limit the adapter's potential speed.
- Интерференция: Адаптерди тоскоолдук жаратышы мүмкүн болгон башка электрондук түзүлүштөрдөн (мисалы, микротолкундуу мештер, зымсыз телефондор) алыс жылдырыңыз.
5.3 Linux Driver Availability
As noted in the specifications, Linux systems require a separate driver installation package. If you are having trouble finding or installing the Linux drivers, please refer to the COMFAST official support website or community forums for guidance.
