Chapter 5: Operation Mode
Gateway mode – (router) under this mode, the rst Ethernet interface is used to connect
WAN as the WAN interface. Other Ethernet interfaces and wireless network interfaces are

www.jcgcom.com 14
connected together via a bridge as the LAN interface.
Network bridge mode – (access point) under this mode, all Ethernet interfaces and wireless
network interfaces are connected together via a bridge. They connect each other easily and
access the superior network via the Ethernet interface. The network bridge mode is also
called as AP mode.
Relay mode—(Client Repeater+AP) under this mode, the wireless network driver will
virtualize a wireless client interface to connect the remote AP. The basic wireless network
interface and all Ethernet interfaces will be connected via bridge as the LAN interface.
Under this mode, keep the working channel same as it of the upstream AP and set up
necessary

www.jcgcom.com 15
parameters for AP client.
Wireless ISP mode—(relay WISP) under this mode, all Ethernet interfaces act as the LAN
interface. The device connects the Internet via the wireless network interface. NAT is
enabled. All LAN hosts access the Internet with same WAN IP addresses via the wireless
network interface. You can select a wireless access point via scanning. Support multiple
network connection modes such as static IP address, DHCP and PPPoE dialing. Under
this mode, keep the working channel same as it of the upstream AP and set up necessary
parameters for AP client and WAN.
AP client mode—(Client) under this mode, the wireless network driver will virtualize a
wireless client interface to connect the remote AP. The basic wireless network interface and
all Ethernet interfaces will be connected via bridge as the LAN interface. Under this mode,
keep the working channel same as it of the upstream AP and set up necessary parameters
for AP client and WAN.

Chapter 6: Wireless Setup
To click the wireless setup main menu, the independent menu will display to set 5G and
2.4G wireless network parameters (WLAN1 represents 5G wireless network and WLAN2
represents 2.4G wireless network). The setup mode is basically same. Taking 2.4G wireless
setup as one example:
6.1 Basic setup
Basic setup: a user mainly sets up the basic parameters of the wireless network such as
wireless network mode, SSID, channel and frequency.
Name of wireless network (SSID)- wireless network identifier, which can distinguish
different wireless networks.
Hide SSID – hide the name of a wireless network, but the client can still manual input SSID
to connect the access point.
Connected client- to click the client, a user can know the information on the client
connected via the current 2.4G wireless network (shown as the following gure).

www.jcgcom.com 17
Generic relay – the wireless network interface is used as the wireless network access
point and wireless network client. The wireless network client interface can connect the
superior router as the WAN interface (switch to wireless ISP mode and select correct
WLAN wireless network interface).
Extend wireless client interface SSID – it is the network name of the superior wireless
network access point which the wireless network client should connect.
Conguration le
– wireless network conguration le, when the wireless network client
is enabled, the authentication information of the access point for client connection can be
stored to the conguration le. When the client connects the access point next time, it can
easily connect the specied access point by selecting a conguration le without the need
of inputting security information.
6.2 Advanced setup
A user can set the advanced parameters of a wireless network with advanced setup.
Packet threshold—the packet threshold decides the size of the data packet which will be
divided (one data block is sent several times). When the communication environment is
not good or the interference is severe, this threshold can be reduced. This threshold can
improve your network performance.
RTS threshold – RTS (Request to Send) threshold decides the size of a data packet.
When this size is reached, AP will send one RTS to clear the channel before sending data.
A smaller RTS threshold is useful when the connected clients are plentiful, or the clients are

www.jcgcom.com 18
remote, or the clients are limited, even reach one.
Beacon interval --- beacon is the small data packets which are used by AP to synchronize
wireless network. The beacon interval indicates the interval of two beacons sent by AP.
Short collision slot – it is used to shorten the communication time between AP and client.
BG protection – a self-adjustment mechanism, which acts as 802.11B standard and can
allow the clients meeting different standard can collaboratively work.
Data packet convergence – multiple smaller data packets are converged and transmitted
as one bigger data packet in order to reduce and control the occupied network bandwidth.
When the network environment is not good or the interference is severe, it can reduce the
network performance.
Transmission power – it can adjust the RF transmission power of the wireless network to
increase or decrease the valid coverage distance and scope of a wireless network.
6.3 Security setup
Here a user can set the security mode and encryption type of a wireless network to prevent
unauthorized clients from accessing your wireless network.
Tip: when the key length is 64 in WEP encryption, please input 10 hex characters or 5
ASCII characters. When the key length is 128, please input 26 hex characters or 13 ASCII
characters.
This router provides wireless network password in the factory default setting, please refer to
the label on the rear side of the shell.

www.jcgcom.com 19
6.4 Access control
Access control --- control connected client to forbid or allow them to connect and access
your 2.4G wireless network.
Allow access – only allow the clients in the list to access 2.4G wireless network.
Forbid access – forbid the clients in the list to access 2.4G wireless network.
Tip:
1. If you are setting up the router with a wireless network connection, when the access
strategy is changed as [Allow], please add the MAC address of the current computer
wireless network adaptor into the access list. Otherwise, you can not connect the wireless
router.
2. The input format of the MAC address is AABBCCDDEEFF without any symbol in this
address.
6.5 WDS setup
Wireless Distributed System (WDS) can extend a wireless network like Ethernet. With
WDS, all access points should work in same channel and MAC addresses (BSSID) of the
access points which should communicate with each other should be added to WDS list.

www.jcgcom.com 20
Tip
1. Before WDS setup, select wireless network type as WDS or AP+WDS (AP+WDS is
recommended) in wireless setup-basic setup, set the channel as it of the corresponding
access point, click Apply and restart and further setup WDS.
6.6 WPS setup
WPS (Wi-Fi protection setup) can allow your wireless network client to easily establish a
connection with the wireless network of the device within several seconds.
PBC mode – the client and access point can establish an connection by pressing
WPS button within specified time (generally it is 2 min). It is also the simplest and most
convenient mode.
PIN mode – the PIN code of the adder is inputted as a PIN of an added party. After
validated by the added party, a connection is established. Generally PIN code is a 8-digit
decimal number.
Tip: when the PBS mode is used for WPS encrypted connection, please notice WPS button
of the router and difference when 2.4G and 5G wireless WPS are enabled. The WPS
button of current JCG “Young” wireless router JYR-AC680 and JYR-AC580 are used as
follows: to click this button, 5G WPS function is enabled. To hold this button for over 5s, 2.4G
WPS function is enabled.
