As a key device in the Internet, routers and L3 switches have been widely used. As people have high requirements on the quality of network services, the functions and performance indicators of routers and L3 switches become more and more important. Route tests include consistency tests, interoperability tests, functional tests, and performance tests. The routing protocol simulation is the basis of the routing protocol. Among the many routing protocols, OSPF is the most complex, and the simulatio

earlier than WRT54GS v4.0 have 8 Mb flash capacity, some routers (including the v5.0 models of WRT54G and WRT54GS) have only 2 MB flash. The full version of the DD-WRT ("full vision") and the mini version ("mini vision") both require 4 MB of flash, while the micro version ("micro vision") requires 2 MB of installation. These support device refresh DD-WRT after the effect is also very poor, I recommend that you have Buffalo WHR G54s, Ausu WL 500G Deluxe and Motorola WR850G these products user re
I would like to introduce you to the method of the wireless router relay function. Many people may not understand the function of the wireless router relay function. It does not matter. After reading this article, you will certainly have a lot of GAINS to make your signal stronger.

, many users have misunderstandings about the compatibility of wireless products when purchasing and using wireless products.
Currently, there are three types of productized wireless network standards: ieee802.11b, ieee802.11g, and ieee 802.11a. The ieee802.11g provides a transmission rate of 54mbps and is compatible with the previous 11mbpsieee802. 11b standard. Therefore, it can not only provide high network bandwidth, but also protect the original investment, thus becoming a choice for wirele
The rapid development of wireless networks has also promoted the wide application of wireless routers. At present, the market demand is also very high. Here we recommend a Cisco wireless router, cisco's Linksys wireless products have always maintained Cisco's high quality. As a result, this WRT54GC Cisco Wireless Router not only has stronger signal and larger signal coverage, but also has a very small size, it's probably as big as a palm. You can even
called, it can contain some parameters. The first parameter is to define the sending method. Here is POST. Then, define the URL for sending the payload. Note: we check the local IP address of the client and then convert it to the default gateway address through the method described above. Then, we add the default certificate of the router.
Wireless users often keep their routers with default access settings. When the requestCSRF function ends, we declare the actual payload to be sent. This is t
SSID of a linksys device is usually "linksys ". If a network does not specify a SSID for it or only uses the default SSID, any wireless client can access the network. Undoubtedly, this opens the door for hackers to intrude into the network.
2. Disable SSID Broadcast
In a wireless network, each routing device has a very important function, that is, the service area identifier broadcast, that is, the SSID br
The US network has been in the Chinese market for several years and won the trust of users with excellent quality, wireless network devices, firewalls, and other security devices, routers, and switches of the network have a large market share in China.

For printers without Ethernet ports, you can purchase a wireless printer server from companies such as Belkin, D-Link, and Linksys. Be sure to select a printer with a USB port and/or parallel port to match your printer. However, you must note that when using this method to connect, the multi-functional device usually loses all functions except the printing function.

At present, China's wireless router industry is developing very rapidly, and its market demand is also very high. Here we mainly introduce Cisco's first dual-band wireless router launched in China, this section describes the features and performance of the vro. In May 19, Cisco launched the Linksys by Cisco dual-band wireless router (WRT320N) in China ). As Cisco's first dual-band wireless router in China, WRT320N aims to help consumers create multime
At present, enterprise-level wireless routers are widely used, especially for small enterprises. Here we mainly introduce the considerations for enterprise-level wireless routers. For small-sized enterprise users, selecting a wireless router saves a lot of trouble. Setting up a wireless LAN saves the trouble of planning and wiring.
Of course, there are many users who need to share Internet access in the enterprise, so the performance requirements for enterprise-level wireless routers are also re
To understand the performance of a Wireless Broadband Router, You need to test its application performance. In the application performance test, there are two items) PRO/Wireless 2200BG. The first objective is to test the single-host access capability at different distance and obstacle intervals. The second item focuses on evaluating the service level and overall throughput of each client under multi-point access conditions.
In the first test, performance data for Cisco
