Configure the wireless gateway from three aspects

Recently, some friends have reported that they are not familiar with the configuration of wireless gateways, so I will explain in detail some questions about wireless gateways, including the selection of wireless gateways, wireless gateway settings and explanations of some related terms.

In a broad sense, a "Gateway" refers to the "interface" connecting a network to another network. For example, if an enterprise's intranet is connected to an external internet, a gateway needs to be managed and controlled. It is a complex network connection device that supports conversion between different protocols to achieve interconnection between different protocol networks. The so-called wireless gateway is a Wireless AP integrated with the simple routing function. In a sense, the wireless gateway solution is exactly the same as the Broadband Router solution, that is, the wireless gateway can complete the functions of the Wireless Bridge and the wireless router through different settings, or can directly connect to the external network, for example, WAN and AP functions.

1. product selection

Currently, there are many wireless gateway products available in the market. In general, all products in the market are small, portable, versatile, and practical. In addition, some products fully consider the needs of users in product design.

Some products have hanging holes on the back, which can be easily mounted on the wall. As a receiver device, you can connect devices such as laptops and network printers to an existing wireless network. Some products have interfaces to connect to the printer, which can be converted into a printer wireless server. Some products also support cameras and can become wireless monitoring devices. When purchasing a service, You must select the service based on your needs.

The following describes the wireless gateway in detail through a specific product.

Product Name: SMC7004VWBR wireless gateway

Product Introduction: it has three modes: Wireless AP, wireless client, and wireless bridging. It has one WAN port and four lanports, and supports 802.11b wireless network connection.

Ii. Product Configuration

According to the previous introduction, we should understand that the wireless gateway itself is an IP sharing device, with built-in PPPoE automatic dialing and DHCP functions, which can provide wireless and wired connection functions; therefore, its configuration is no different from that of a wireless router. The main configuration of a wireless gateway is to enable the automatic dialing function. Here we only use Intel WLGW2011BAK wireless gateway as an example to introduce the configuration and debugging process.

Step 1: After the computer and wireless gateway are connected, enter the default IP Address "192.168.2.1" in the address bar of the browser. (the default IP addresses of some wireless APS or wireless gateways are different, see the product manual). Press enter and then enter your account to enter the management interface.

Step 2: click the "Save/Next" button in the lower right corner twice, and then click the "Cable/DSL Settings" button to go To the configure wireless gateway automatic dialing page.

Step 3: Check "PPPoE Username/Password", enter the User Name for ADSL dialing after "User Name (PPPoE)" below, and then click "Password (PPPoE) "and" Retype Password "enter the Password twice, and then press" Apply "in the lower right corner of the page to save the settings.

After the configuration is complete, you are advised to check the connection status of the device and whether the wireless and wired functions are properly connected through the check options provided on the management interface. In addition, you may encounter some common problems. You can find a solution from the user manual and the simple troubleshooting manual attached to the CD, such as wired connection, however, wireless connection is not possible.

Step 4: Set advanced settings.

Generally, an "Hide AP Access setting (indicating hiding AP Access) is displayed on the Wireless AP or wireless gateway configuration interface. If this option is selected, the wireless terminal cannot scan and discover the AP even if it is within the signal coverage of the Wireless AP. You can connect to and access the AP normally only by knowing the SSID value set in the Wireless AP. This function protects AP security and blocks access from illegal users.

Of course, the setting interfaces of different products are certainly different, but the parameters set are similar. Any product can be easily started as long as you understand the parameters to be set and their meanings.

Iii. Common Terms in configuration

On the wireless gateway configuration page, we often see many configuration terms. Understanding the meanings of these terms makes the configuration process easier. In other products, it can also be easily configured.

A Channel is a Channel equivalent to a TV. In general, the configuration program attached to the wireless network adapter has a function that is used to scan which channel of the current connected AP has the best signal. In a general family environment, you can select the region.

AP name when multiple APS work in the network, each AP must have its own name for ease of management. You can enter any information as needed. Because there is only one AP in the family, it is used in the same way as the SSID recognition.

Mode AP can work in three modes. AP is connected to wired and wireless networks and serves as a transparent bridge. Repeater refers to the relay Mode, which can extend the coverage of wireless signals, connect two or more scattered networks. AP + Repeater allows the AP to work in both AP and Repeater modes. Obviously, for home users, the AP mode must be selected.

SNMP is a standard protocol for network device management and monitoring. You can Enable this protocol.
