1.4 What Can I Do If I Fail to Log In to the Eweb Management System?
(1) Check that the network cable is properly connected to the LAN port of the device and the corresponding
LED indicator blinks or is steady on.
(2) Before accessing the configuration GUI, configure automatic IP address assignment (recommended), so
that the server with DHCP enabled can automatically assign an IP address to the PC. To allocate a static IP
address to the PC, set the IP address of the PC on the same network segment as the IP address of the
management interface.
(3) Run the ping command to test the connectivity between the PC and AP.
(4) If the fault persists, restore the AP to factory settings.

Note
Reyee devices on a network use the same login password.
2.3 What Can I Do If I Forget the Password?
If you manage your ReyeeAPs on Ruijie Cloud, you can modify the password through Ruijie Cloud.
If the Reyee AP is not deployed on Ruijie Cloud, you can press the reset button on the AP for more than 5s
to restore factory settings.
Caution
Restoring factory settings will delete the existing configuration, and you are required to configure the AP again
at your next login. Therefore, exercise caution when performing this operation.

3 FAQs About PPPoE Failures
3.1 What Should I Do If a PPPoE Connection Fails to Be Set Up?
(1) In Local Device mode, choose Network > WAN and click View PPPoE Records to obtain connection logs.
(2) Check whether the PPPoE account and password are correct.
(3) Check whether the IP address assigned by the ISP conflicts with the IP address on the AP in router mode.
(4) Expand Advanced Settings and check whether the MTU setting of the AP meets requirements of the ISP. If the
MTU is incorrect, change it.
(5) Check whether the VLAN tag needs to be configured for PPPoE.
There is no VLAN tag for PPPoE by default. If the VLAN tag is required, you can enable 802.1Q Tag and set
VALN ID.

5 FAQs About Slow Internet Access Through Reyee
APs
5.1 What Should I Do If Internet Access Is Slow?
Compare test speed results of a PC connected directly to the ISP router or modem and a PC connected to a
Reyee device. If the results are the same, the ISP router or modem may fail. If the results are different, perform
the following steps.
(1) In Local Device mode, choose Advanced > Port Settings and check whether Flow Control is enabled.
(2) Replace the network cable for testing.
If the wireless speed is still slow, continue with the following steps to Change Wireless Channel, Transmit
Power, and Channel Width for the ReyeeAP. You may change the 2.4 GHz channel width to 40 MHz and 5
GHz channel width to 80 MHz.

7 FAQs About SON
7.1 What Is SON?
Self-Organizing Networking (SON) eliminates product limitations and realizes auto-discovery, auto-networking,
and auto-configuration between routers, switches, and wireless APs without the need for controllers or Internet
access. You can quickly complete device deployment and configuration, remote management, and operation
and maintenance of the entire network with Ruijie Cloud App, which greatly reduces the investment of device,
labor, and time cost during wireless network construction.
7.2 Which Devices Can Act as the Master Device on the SON?
The EG, NBS switch, and Reyee AP can act as master devices.
Note
Ruijie EG3230/3250 and Reyee ES switches cannot act as master devices.
7.3 What Is the Priority of Devices During Master Device Election of the
SON?
For different types of devices, the EG in AC mode, EG in router mode, AP in router mode, AP in AP mode,
and NBS switch are in descending order of priority.
For devices of the same type and different models, the priority is related to the CPU, memory, and other
parameters (for example, AP radio number) of the device. Alarger parameter value indicates a higher priority.
For devices of the same type and model, a larger MAC address indicates a higher priority.
7.4 How Is SON Enabled on Reyee APs?
(1) In Local Device mode, choose Overview > Device Details.
(2) Click the current working mode to change the working mode.
