If there is no wireless router, a laptop with a wireless network card can also build a LAN.
Now, more and more users are using laptops. To make it easier for users to move their offices and access the Internet at any time, some families or organizations use wireless routers to build a
When there is no wired broadband access and no wireless network adapter, the wireless LAN cannot access the Internet. So how can I access the Internet through a wireless lan? That is, how does one achieve
line distance of about 60 meters. The connection cannot be established when the window is closed, however, you can move the network adapter and AP to the window and open the window to establish a connection, but the data transmission is not stable. How can this problem be solved.
Cause and solution:
To make the transmission distance longer or enhance the transmit power, you can purchase a separate antenna. Otherwise, the signal transmission speed and

Knowledge: point-to-point Wireless Networks
A wireless Interconnected Network, also known as point-to-point automatic networking. Such a network implements a Peer-to-Peer or Peer-to-Multi-Peer Ad-Hoc network through software, in this network, the wireless network adapter will au
although the 802.11g product can be regarded as an upgrade of the 802.11b product, the advantages in compatibility, stability, coverage, and price are not obvious. First, the 11 m transmission speed of 802.11b is higher than the access speed of Common Household broadband types such as DSL and LAN, which can fully meet the needs of domestic users for wireless broadband Internet sharing.
Second, the price of
network adapter along with the location when accessing public wireless access networks that support 802.11a and 802.11b, this brings great inconvenience to users, and the use of wireless LAN products that support 802.11a/B dual-band adaptive can solve this problem well. Dual-band products can automatically identify 80
A lot of work is inseparable from computers, so many friends are also equipped with laptops. This kind of mobile computer is very convenient, so if you want to share the connection between two laptops, wired components cannot be made anytime, anywhere. Let's take a look at the procedure of building a wireless LAN in a notebook.
First, let's take a look at the basics of interconnection before building a
monitor the traffic in the wireless network and check the network and troubleshoot.
Difference between promiscuous and monitor (rfmon)In a traditional finite network, we know that NICs can work in two modes: Common and hybrid. In promiscuous mode, we can directly listen on Intranet traffic over Ethernet. At this time, the network adapter will not distinguish whether the destination address of the data pack
It is not difficult for the applications of Wireless LAN, whether in the home or enterprise. This article describes how to set up a home wireless LAN. The content is very detailed. Basically, through this article, we generally set up a home wireless WLAN.

Distance, direction, or obstacle is also one of the root causes of the problem.
The distance between the wireless router and Wireless Access Point of the master machine and the sub-machine Wireless LAN signal LAN card and wireless
as upgrades to 802.11b products, the advantages of compatibility, stability, and coverage and price are not obvious. First of all, 802.11b products 11M transmission speed than DSL, LAN and other common broadband type of access speed, can fully meet the needs of home users wireless broadband sharing Internet. Second, 802.11b products in the price is easy to accept, from the current price, the same brand of

The US network provides a one-year warranty for the WGT624 sans M wireless router and wgw.t sans M wireless laptop card, ensuring the quality of after-sales service for users.
With the development of the 802.11 standard, the performance of wireless networks will be closer

Assume that host B wants to know what the FTP password for logging on to server C is, what it wants to do is to capture the data frame broadcast by host A and parse the data frame, extract the Ethernet frame header, IP packet header, and TCP packet header, and analyze the header and data to obtain useful information contained in the data frame.
When implementing sniffing, first set the computer used for the wireless
