Now the embedded device networking, there are two main modes: Ethernet RJ-45 interface directly plugged into the Internet network; 3g/4g module dial-up Internet access. With the continuous popularization of wireless terminal equipment, mobile phone plate and other wireless devices to the network demand is increasing. This article mainly introduces the design of wireless router based on embedded Linux, and accesses the network in a
. This information is stored in the FLASH of the router, unless you delete this information yourself, otherwise, the route information remains in the static database.
Example 1: the router sends data packets sent to the 0800. cb00.45e9 address from the interface ethernet0.
Quidway (config) # bridge address 0800. cb00.45e9 forward ethernet 0
Example 2: delete the
When do I use WDS bridging?
It is generally used in a large area, a wireless router with limited signal coverage, making certain areas of the site without signal or weak signal; This can add a wireless router and configure the WDS bridge to allow wireless WiFi coverage throughout the site.
To set the method for Tp-link tl-wr742n
Cascade tl-wr845n Router WDS Bridge setup Step 1
To view the wireless parameters of the main router, enter the settings interface of the master router to view and record: Wireless signal name, wireless encryption mode, wireless password, wireless channel (channel please set
unsuccessful solution of wireless bridging in tp-wr842n router
The wireless router is set up WDS Bridge, not on the network, login to the management interface of the router, in the running state >> wireless status, WDS status continuously display scanning, initialization, association, etc., indicating that wireless WD
switch is often used to connect to an independent computer, rather than a LAN.
Therefore, when host a in Figure 1 wants to send a frame to host B, after the bridge gets the frame, it only discards it. On the contrary, in Figure 2, the switch must actively send frames from host a to host B, because there is no other way (PATH) to complete Frame Forwarding from host a to host B. Because each port of a switch is usually connected to a computer, the swi
Because Tengda customer service informed, Tengda router WDS will be compatible with this situation, then we can not solve the problem of WDS other router products.
1, first of all, we enter the router Settings page, is generally 192.168.0.1 in the homepage to change a wireless password, of course, you go to the advanced settings to change the wireless password i
Which layer does the repeater, Hub, switch, bridge, and router correspond?
First, we need to analyze the functions of each device in detail:
I. RepeaterRepeater works on the first layer (Physical Layer) of OSI. Repeater is the simplest network interconnection device that connects two or more network segments in the same network. It mainly implements physical layer functions, transmits information by bit on
Router tplink845 wireless Bridging method:
The main and the secondary routers through the wireless bridge, the wireless terminal may connect the main, the auxiliary router surfer, the movement process may automatically switch, realizes roams. The topology is as follows:
To confirm the wireless signal name, wireless password, and wireless
A repeater or hub cannot isolate a conflict domain and cannot isolate a broadcast domain, a bridge or a switch can only isolate a conflict domain from the broadcast domain, and the router can isolate the conflict domain and isolate the broadcast domain.ResolutionThe first thing to know is the conflict domain and broadcast domain, when a piece of network card send information, it is possible to conflict with
exist, the switch broadcasts all the ports. After receiving the port response, the switch "learns" the new address and adds it to the internal address table. The forwarding delay of a vswitch is very small, mainly because the hardware design mechanism is very efficient. To support the maximum data transmission rate of each port, the bandwidth of the forwarding packet inside the vswitch must be much larger than the port bandwidth, with a powerful overall throughput, each workstation can be provi

Tengda ww.r router settings-wireless encryption
The tengda ww.r router provides two interfaces for setting encryption, one for simple operation and the other for advanced settings.

Early domestic ADSL line access are bridge mode, by ADSL modem and computer, in the computer to allocate fixed IP address, boot can access to the local terminal equipment into the Internet. However, when the user does not boot on the Internet, IP is not to be exploited, will cause the current increasingly scarce public network IP resources waste, so there has been a PPPoE dial-up ADSL access.

CC bought a 300M wireless broadband router in the east of Beijing Mercury mw300r, do not know is due to the new model, or the router is too bad, or Acer notebook wireless card is too bad, engaged in an afternoon, including the Reload wireless network card driver, update the latest wireless network card Atheros_wifi_ 10.0.0.221 Drive, wireless network card model Atheros ar5b93, Wood has to solve the problem.
has been introduced to you before the problem of wireless relay, below I give in the vast numbers of netizens introduce Lei branch Router bridge concrete steps.
First, preparatory work
(1) Two lei ke nw715p wireless router, hereinafter referred to as P1,P2.
