Chapter 13: FAQ
Why is the Wi-Fi signal weak and how can I improve it?
Weak Wi-Fi signal may come from the following reasons:
• The router is too far from the client devices.
• The router's Wi-Fi transmit power is not strong enough. Go to
Network Center
>
Wireless
>
Wi-Fi
>
Advanced options
, and change the
Transmit power
level (Low, Middle, High).
• There might be interfering barriers (e.g. concrete or metall walls) that can severely reduce Wi-Fi signals. 5GHz
Wi-Fi is more sensitive to barriers than 2.4GHz. Refer to "Set up Your Wi-Fi Connection" for more information.
• Nearby devices (e.g. microwaves/wireless phones, USB 3.0 devices, and other routers) may interfere with the
router's 2.4GHz Wi-Fi transmission.
To improve Wi-Fi signal strength, you may try the following solutions:
• For RT1900ac, adjust the antennas to make them 45 degrees apart from each other. If the Wi-Fi strength is not
boosted, you may try other angles to nd out the best antenna placement.
• Relocate your router to the center of the area where the client devices are placed, or to a position where the
router and the devices are within a visible distance without interfering barriers. Optimal placement depends
heavily on the actual environment and may be inuenced by interference sources.
• If there are radio transmitting devices near the router, to avoid channel overlapping, re-assign their operation
channels to channels 1, 6, or 11 (for devices using 2.4GHz Wi-Fi); to any non-overlapping channels (for
devices using 5GHz Wi-Fi).
• If set to "Auto", SRM will try to determine a less congested channel.
Why can't I boost a device's signal with beamforming?
• Only six devices can concurrently receive beamforming.
• Make sure your device supports beamforming too. This means the device must conform to the 802.11ac
standards.
• RT2600ac performs beamforming for all supported Wi-Fi connections by default.
Which Wi-Fi frequency (2.4GHz and 5GHz) should I choose?
Please see "Set up Your Wi-Fi Connection".
Why can't I nd the router's 5GHz Wi-Fi network?
Due to previous NCC (National Communications Commission) regulations, in Taiwan wireless devices
manufactured before 2009 cannot make use of the 5GHz Wi-Fi channels 36-48. To help such wireless devices
connect to the 5GHz Wi-Fi network, you should use alternative channels rather than channels 36-48 (at
