wireless network? To eliminate all interference from wireless Internet access, I intend to temporarily cancel these security settings. However, when I try to disable all firewall and MAC address filtering functions of the wireless router, it is found that the old IBM T30 la
network has no signal
Fault analysis
There are several possible causes for this failure:
(1) wireless network card distance from the wireless AP or wireless router is too far, more than the coverage of wireless networks, wireless signal to reach the
selection, we can see that all the Broadcast SSID and the wireless networks that disable the broadcast can be clearly displayed in the window on the right of netstumbler, the recorded information includes the currently working wireless network and the previously scanned wireless network information.
(2) scanning by DD
WLAN (Wireless Local Area Network) is a combination of computer networks and wireless communication technologies. Specifically, traditional cables are no longer used to establish a LAN, and infrared and radio waves are used as transmission media to connect to the LAN in a wireless manner, providing all functions of the

In a small office, you can activate China Telecom ADSL Broadband and use a NETGEAR wireless router to share the Internet. In the corner of the meeting room, the signal is weak. How can we effectively improve the coverage of wireless networks?
Solution
Confirm that the original model supports the wireless relay (WDS) function, purchase a new Netgear
the hidden SSID wireless network. First, install netstumbler and then select the NIC for scanning. From the scan results, we can see that some network SSID information is empty, these networks are wireless networks that hide SSID broadcasts. For example, in this example, the MAC address is 001122334457, however, even if the SSID information is hidden, we can use netstumbler to learn about its basic paramet
, which allows you to buy a wireless network card separately ".
The built-in MiniPCI wireless Nic does not integrate a signal antenna. Therefore, to install the MiniPCI Nic, in addition to requiring the laptop to reserve a MiniPCI slot, you must also have a preset antenna or a preset antenna. Not all brands of MiniPCI interface
My old friend xiaohou successfully ranked among the "white-collar" after graduation. This public network is like life, and soon I bought a kind. Whether at home, at work, or at Starbucks, he always takes the time to open his laptop and find wireless hotspots. Today, we are connected to the wireless route of the next-door neighbor, and tomorrow we will find another coffee house with no money to access the In
, the first thing to do is placement problems. The function of a wireless router is to convert the signal of a wired network into a wireless signal, which is the core of the entire a wireless network. Therefore, its position determines the signal strength and transmission rate of the entire Wireless LAN. Therefore, we
generation of network information equipment Exchange technology and Interface specification, in the communication and content security mechanism guarantee, support all kinds of 3C equipment intelligent interconnection, resource sharing and collaborative services. At present, all wireless cards support the "flash" standard, with "flash-free" software, equipped wi
administrators and security officials. Any computer can connect to the network without authorization through the AP purchased by itself. Many departments build their own wireless LAN without authorization from the company's IT center. Illegal AP access brings great security risks to the network.

More than half of users only make few changes based on the default configuration when using the AP. Almost
The development of WLAN technology is already making our lives more convenient. How can we set up WLAN Access Points controlled by wireless LAN switches? This article introduces you.
Do you want to achieve a signal without interference and a stable wireless network connection? WLAN wireless LAN switches can be configured to fully control
)Many students have already set up a wireless network at home, but because of obstacles such as wall blocks, so that the wireless signal attenuation is very strong, in order to solve this problem, I believe many students have begun to try to use Wireless bridge routers at home to expand the scope of wireless networkBut

A Wireless AP is equivalent to a wireless switch that is connected to a wired switch or vro and gets an IP address from the vro for the wireless Nic connected to it.Then distinguish from the application

At present, many laptops have their own 802.11b/g wireless network adapters, and there is no need to install a wireless network card to connect to the wireless networks. Often, however, the problem is that laptops that have not been used wirelessly or have connected to a wireless network will not be able to connect to

after that, how to switch frequency band?
Some dual-band wireless network cards are supported in the Windows XP operating system to toggle the working band. In the Win7, WIN8, Win10 operating system, can not switch the working band, the default work in the 2.4G band.

network speeds will naturally slow down. In this case, you can use software (such as WirelessMon) to check which channels are used by nearby hotspots, remember the channels that are least occupied, and enter the Web Settings interface of the wireless router, manually adjust the channel of the wireless router to improve the wireless experience.
