This script is to automatically test whether a node in the wireless network with a long-hanging machine in case there is a drop condition:

The wireless router uses NETGEAR WGR614 (54M is 802.11g), and the NIC is also 54M (the configuration is very smooth, so I did not carefully look at the specific model). The reason why
controller maintains the authentication and encryption status of the client.
3. Independent controller roaming (only one wfs709tp in the environment)
1. l2 (Layer 2) Roaming
Note: AP1 (1.1.1) and AP2 (1.1.2) are on the same wfs709tp, And the broadcasted SSID is the same and on the same VLAN. When the client is roaming from 1.1.1 to 1.1.2, the IP address and encryption of the client are maintained in wfs709tp. During the roaming process, no IP address changes or re-Authentication occurs. Only
. Therefore, "One thing" depends on the status of abstraction.
The following method completes too many things. Let's look at the actual code:
Private uint status;Private uint unique ID;Private uint flags;Public string CheckDogAndGetKey (){Flags = SentinelKey. SP_STANDALONE_MODE;Status = oSentinelKey. SFNTGetLicense (Region ID, oSentinelKeysLicense. SOFTWARE_KEY, SentinelKeysLicense. LICENSEID, flags );If (status! = SentinelKey. SP_SUCCESS){Throw new FileNotFoundException ("A valid
to the code in the previous recommendation, where the Localinit method and the Remoteinit method are two things, but at the same level of abstraction, it is possible for the type to be merged into the "Initialize" thing. Therefore, the "same thing" depends on the position of abstraction.The following method has done too many things, so let's look at the actual code:
private UINT status;
private UINT Developerid;
private UINT Flags;
public string Checkdogandgetkey (){Flags = Sentinelk

Maybe many people are not very familiar with how to buy a wide M Wireless Broadband Router. Next we will mainly explain the purchasing skills of the wide M Wireless Broadband Router. The quality of vro products on the market is uneven and prices vary greatly. This is the case for products of the same grade, not to mention products of different grades. Therefore, it is really necessary for consumers to make more efforts when purchasing vrouters. Next we will introduce the two TP-LINK TL-WR642G an

Because of professional reasons, although I used to pay attention to the wireless router configuration in this respect, but because there is no actual operation and flow on the surface, the last few days can not resist the temptation to do a set of Net
During the test, the dongle intercepted the SQL query on the website where the dongle was used. However, the dongle was able to bypass the security and obtain the database information. For the protection device, if important information is obtained by the passer when it is enabled, I think it has been bypassed... the test procedure is as follows: bbs.siteserver.c
I haven't been back to my hometown for the new year for many years. I went back to my hometown with my wife and baby for a spring festival last year. When I came back and saw my blog for more than a month, I couldn't help but sigh that the time was so fast. Last year, I published a FastReport-based Web Printing control on the Internet, which attracted everyone's attention. Many friends leave a message to apply for free registration. I try to send the registration code to your email as quickly as

The main devices required for networking are one adsl moodem, one Broadband Router, and two switches. In consideration of security, we also need to install a hardware firewall.
The topology is as follows:

With the development of China's wireless routing industry, we have also promoted the upgrade of the wireless router technology. Here we mainly explain the wireless router's network security and ease of use. WPN824 has rich functions, it inherits the traditional advantages and features of NETGEAR and has a simple and easy-to-use WEB configuration interface.
In addition to the basic functions of WLAN gateway, it also provides advanced functions such as

Because of my career, although I used to pay attention to the wireless router configuration, I failed to follow the surface because I didn't have the actual operation.

"IT168 technology" with the increase in mobile terminals, the demand for wireless routers more and more high, I do not want to buy a wireless router, I searched the internet, and found that the wireless router can be brush "ddwrt" to increase the function, we are a very strong hands-on ability, but also not afraid of brush bad, I decided to brush my Netgear WNDR3400 wireless router to see the effect.
The first thing to say is that any manufacturer ha
