, change the default SSID settings
In the default state, the manufacturer of the wireless network node uses the SSID (initialization string) to verify connection requests that attempt to log on to the wireless network node, and may be successfully connected to the wireless network once the test is passed, but since the same SSID name is used by the same manufact
, operators provide the bandwidth is the bottleneck, and different levels of wireless routers in the wireless LAN to give users different transmission speed and the range of signal coverage.
So for the average home users, the current mainstream 54M wireless router can fully meet our demand for BT download.
3. Turn off the SSID
The SSID (Servicesetidentifier) is typically the local area network name that
based on this principle, has led to a lot of BT users in the download when the flow of stop and slow phenomenon. Of course, for the wireless router, we also need to make some additional settings to get the same download effect as the wired network.
Turn off SSID
The SSID (Servicesetidentifier) is typically the local area network name that is broadcast by the AP or wireless router, and is designed to allo
Major brand manufacturers in the wireless router configuration design has increased the key, prohibit the SSID broadcast and other means, but these security settings are really effective?
As more and more friends enter the "wireless" family, the safety of wireless networks has attracted much attention. In contrast, wireless is more difficult to protect than a wired network, because the number of fixed physical access points in the wired network is li
Are we free to use these wireless products when we buy them home? The answer is no, it's not casual in the process of using these wireless products, especially when there are no lines set up. The author of this article will introduce you to the use of wireless products in the process of security should pay attention to the misunderstanding, to help users create a more High-performance home wireless network.

some wireless routers (such as tp-link) products, not only provides the ability to modify the wireless router password, but also provides the ability to modify the user name of the wireless router.
Take Tp-link's tl-wr641g as an example, the user can modify the username and password at the same time as the login password (pictured below). After modification, the intruder will not easily enter the wireless router device, Wireless LAN Security is also protected. (Computer science)

First, if you want to prevent unauthorized users from quietly accessing the wireless ADSL cat, do not broadcast the SSID. SSIDServiceSetIdentifier) can also be written as ESSID, used to distinguish between different networks, can have a maximum of 32 characters, wireless network card configured with a different SSID can enter a different network,
users to be interrupted and slow during download. Of course, for wireless routers, we still need to make some additional settings to achieve the same download effect as the wired network.
Disable SSID
SSIDServiceSetIdentifier) is generally a LAN name broadcast by an AP or a wireless router. It aims to allow computers with the same name and SSID to communicate with each other.

Recently, wireless networks are gaining momentum, and the slogan of popularizing wireless networks further occupies the market. The price of wireless product packages also drops, but it cannot be left blank when many friends encounter various problems when installing and configuring wireless networks. This article describes how to operate the wireless network card installed on the computer to connect to the Wireless Broadband Router and build your own wireless LAN.

2.1 use wireless encryption protocol to prevent unauthorized users
The most basic method to protect wireless network security is encryption. You can enable WEP Encryption By simply setting AP, wireless network card, and other devices. The wireless encryption protocol (WEP) is a standard method for encrypting traffic on wireless networks. Many wireless device vendors disable the WEP feature when delivering devices to facilitate product installation. However, once this approach is adopted, hack
