Wi-Fi
What can I do if I forgot the Wi-Fi SSID and its password?
• As the administrator, log in to SRM via wired connection and go to
Network Center
>
Wireless
>
Wi-Fi
to nd
out the Wi-Fi SSID and password.
• If you forgot the administrator's login credentials, you may perform Soft Reset to reset the Wi-Fi SSID and its
password. For more information, please see "Reset Synology Router".
Why did my Wi-Fi SSID disappear?
• Check if the Wi-Fi network is enabled (at
Network Center
>
Wireless
>
Wi-Fi
) and if the Wi-Fi switch is set
"ON" on the Synology Router.
• Check if the SSID status is "Show" (at
Network Center
>
Wireless
>
Wi-Fi
). Then disable the Wi-Fi network
and enable it again.
Why can't my device connect to the Synology Router wirelessly?
• Check if the Wi-Fi button on your router is set "ON", the Wi-Fi feature is enabled in SRM, and the antennas are
well-installed.
• Check if the device is too far away from the router or if there is any obstacle/electrical signal source that may
interrupt the Wi-Fi connection.
• Check if your wireless device is connected to the Wi-Fi network hosted by the router. If the device is not in the
router's local network, you cannot access SRM via router.synology.com or its local IP address.
• Move your wireless device closer to the router and reconnect again.
Why can't my wireless devices communicate with each other though they are
in the same Wi-Fi network?
AP isolation may have been enabled (at
Network Center
>
Wireless
>
Wi-Fi
>
Advanced options
). AP isolation
prevents wireless client devices that join the same Wi-Fi network (2.4GHz or 5GHz) from communicating with
each other.
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 distant 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 intervening barriers (e.g. a large expanse of metal) that can block Wi-Fi signals. 5GHz Wi-Fi is
more sensitive to such barriers than 2.4GHz, as mentioned in "Set up Your Wi-Fi Connection".
• Nearby devices (e.g. microwaves/wireless phones) using the same frequency band may interfere with the
router's 2.4GHz Wi-Fi transmission.
To improve Wi-Fi signal strength, you may try the following solutions:
• Adjust the antennas to make them 45 degrees apart from each other as recommended in "Install Antennas". 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. However, the two locations may
not always work, and you may try other locations to nd out the best router placement.
• 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).
