transmission power from the drop-down menu to reduce the output power of the router. Your options include 100%, 50%, 25%, and 12.5%. A Beacon Interval beacon is a data packet sent by an access point for synchronizing data to a wireless network. Specifies a beacon value between 20 and 1000. The default value is 100 milliseconds. The default value of this paramete

first. First, let's take a rough look at the resources and advantages of the other party. Is there anything we want. Then, let's take a preliminary look at whether the other party is interested in our resources. What can we give to the other party! If you can find a reliable cooperation model, it is best. AStep 3: Find the combination points of both partiesWhen we confirm that we have the possibility of cooperation with the other party, the two sides will formally contact and negotiate. This st

to high current. Within 10 minutes between screen disconnection and disconnection, if it is normal, when the cpu Of the tablet is sleeping, the average current should be only 1ma higher than that of the wifi chip (this value is the sleep current of the wifi chip); however, in this case, the average current measured will be higher than 1ma, this requires us to analyze the cause. Some points related to current may not be completely recorded here. If you find them again later, supplement them. 1.

interconnected, non-infrastructure sites that are designed for point-to-point connectivity. IBSS mode does not have a wireless infrastructure backbone, but requires at least 2 sta.3.1 Binding identifiersBased on the description of the Capwap header in section 4.3 of RFC5415, the Wbid field identifies the wireless technology being bound. For 802.11, the field is evaluated to 1.3.2 Functional DivisionsSince Capwap is protocol-independent, when binding 802.11, it is necessary to divide the functio

-ds.png) Looking at this feature carefully, it is not difficult to find a lot of articles to do-this is not a natural preparation for us to fish! Let's start another pseudo-hot spot with the Same Name authentication. As long as the signal is overwhelming, it is appropriate to catch nearby fish. At present, there are almost no clients to defend against this problem. No matter whether it is a mall, a coffee shop, or even some large companies, this is also helpless. The reason is very simple. The

. Beacon logCurrently, the most popular method on the Internet is to request beacon server when the user's browser accesses the target Webpage through a small piece of code embedded in the webpage. Generally, a configuration server can easily support log records with tens of millions of PVS. Google Analytics is a common statistical tool for small websites.

file. However, an EXE file (also known as a portable executable, that is, PE, because it contains all the information that is required by Windows to run) is a problem in that it usually has to be written to disk, but in this way it is easily discovered by AV software. We know that the various Red team tools (from Metasploit to cobalt Strike) are able to generate an EXE file that connects the attacker's machine via the C2 channel. Although each of these files is not the same (which ensures that

What's ibeacon? 1.iBeacon is based on the latest Bluetooth Low-power 4.0 technology, which can be used to build a signal base station, when the user holds the IOS device into the area, you will get the push information of the base station. ibeacon How to use 1. First of all, it is important to note that, to experience this new technology, a number of conditions are required. The first is the iOS7 system, and the other is the iphone4s or iPad2 and later devices. Here for you to recommend a sof

why? The cause of this failure is many, different reasons need to adopt different methods to deal with, which hardware failure causes more common, such as network cable break or short-circuit, network connection connector appeared loose phenomenon, wireless router itself has hardware failure. For hardware failure reasons, we usually can determine if there is a problem with the hardware by looking at the status of the beacon in the control panel of t
