EDUP USB WiFi Adapter 1300Mbps, USB 3.0 Wi-Fi Dongle 802.11 ac Wireless Network Adapter with Dual Band 2.4GHz/ 5.8GHz 5dBi Antenna for Desktop Windows XP/Vista / 7/8.1/10 / Mac 10. Wi-Fi 6 also sends and receives multiple streams of data simultaneously and reduces latency, providing up to 4x more capacity compared to Wi-Fi 5 technology. So, it can handle the demands of up to 50 devices, from laptops and gaming consoles to smart home devices and 4K TVs, all competing for the same bandwidth. We apologize for any inconvenience you may encounter while using Wi-Fi Transfer. We improved a connection logic in the latest Wi-Fi Transfer 2.0. If you update Wi-Fi Transfer to the latest version, you will use the new Wi-Fi Transfer that upgrades usability and tutorial. We will continue to provide better functions in the future.’
Starting in Android 8.0, Android devices use randomized MAC addresses when probingfor new networks while not currently associated with a network. In Android9, you can enable a developer option (it’sdisabled by default) to cause the device to use a randomized MAC addresswhen connecting to a Wi-Fi network.
*Wifi direct free download - WiFi Scanner, Easy WiFi, Hotspot Shield, and many more programs.
*Tap Wi-Fi Direct to set up your Wi-Fi Direct connection settings. Checkmark the Wi-Fi Direct checkbox to turn it on. A pop-up screen with instructions on how to connect with Wi-Fi Direct and Wi-Fi devices appears after checking the Wi-Fi Direct checkbox.
In Android 10, MAC randomization is enabled by defaultfor client mode, SoftAp, and Wi-Fi Direct.
MAC randomization prevents listeners from using MAC addresses to build a historyof device activity, thus increasing user privacy.
Additionally, MAC addresses are randomized as part ofWi-Fi Aware andWi-Fi RTT operations.Implementation
To implement MAC randomization on your device:
*
Work with a Wi-Fi chip vendor to implement the following HAL methods:
*IWifiStaIface#setMacAddress: Configures the MAC address of theinterface. The default implementation brings the interface down, changesthe MAC address, and brings the interface back up.
*IWifiStaIface#getFactoryMacAddress: Gets the factory MAC of wlan0using an ioctl call.
*ISupplicantP2pIface#setMacRandomization: Sets P2P MAC randomizationon/off in the supplicant.
*
Setconfig_wifi_connected_mac_randomization_supported to true in the Settings config.xml (this can be done in a devicecustom overlay).
*This flag is used to control whether client-mode MAC randomization isenabled.
*
Setconfig_wifi_p2p_mac_randomization_supported to true in the Settings config.xml (this can be done in a devicecustom overlay).
*This flag is used to control whether Wi-Fi direct MAC randomization isenabled.
*
Test your implementation using the methods described inValidation.
The System UI must:
*Have an option to enable or disable randomization for each SSID.
*Have MAC randomization enabled by default for all newly added networks.
Use thereference implementation of Settings UI to implement new prompts.
Devices running Android 9 or lower might not havesupport for Wi-Fi MAC randomization. When upgrading such devices to Android10, the Wi-Fi MAC randomization feature can be disabledby setting the WIFI_HIDL_FEATURE_DISABLE_AP_MAC_RANDOMIZATION flag to true inthe Wi-Fi vendor HAL make file.Validation
To validate that the feature is working as intended, run both an integrationtest (ACTS) and a manual test.
To run an integration test, use the ACTS file,WifiMacRandomizationTest.py, located intools/test/connectivity/acts/tests/google/wifi, to verify that the device usesthe randomized MAC address and correctly stores the randomized MAC address foreach network.
To run a manual test:
*Verify that MAC randomization is enabled on the device by checking thatconfig_wifi_connected_mac_randomization_supported is set to true in thedevice overlay.
*Connect to a Wi-Fi network.
*Tap the network to go to the Network details page. Verify that MACrandomization is turned on. Verify that the MAC address displayed is arandomized MAC, which has the locally generated bit set to 1 and themulticast bit set to 0.
*Turn MAC randomization off. Connect to the same network and verifythat the factory MAC is being used.
*Delete the network by tapping Forget on the Network details page.
*
Connect to the same network and verify that the same randomized MACaddress is being used.Note: Randomized MAC addresses are generated per SSID and are persistent.
To test MAC randomization on a pre-Android 10 device(capable of supporting MAC randomization) upgrading to Android10 or higher:
*Have at least one saved network on a device runningAndroid 9 or lower.
*Flash the Android 10 system image.
*In the Wi-Fi picker, verify that MAC randomization is turned off for allsaved networks.
*Turn MAC randomization on. Connect to the same network and verifythat the randomized MAC is being used.Note: You may experience up to a three-second delay when connecting to anetwork due to the driver flushing saved scan results when theinterface goes down. If this is the case, check with your siliconpartners to resolve the issue.
/Mac Cleaner /Enable Wi-Fi Direct on Mac to Generate More SharingWifi Direct For Macbook
As increasing new functions are designed for smartphones or other electronic devices, it is easy for some users to ignore or underestimate certain functions in spite of their usefulness. Such functions, sometimes, can bring great convenience and influence.
What had to be mentioned here is Wi-Fi Direct. It is one of the most useful functions but neglected by users. You may have no idea of this term, however, you probably heard someone surrounding asked something about it, like ’What is Wi-Fi Direct?’.What Is Wi-Fi Direct for Mac?
Wi-Fi Direct for Mac is mainly for data transferring and sharing, a function much more similar to Bluetooth. You are required to connect to other devices instead of the router when using Wi-Fi Direct. You need to establish a connection between two devices that can support and enable Wi-Fi Direct so as to share or exchange data.
Therefore, in this article, you will know the brief introduction to Wi-Fi Direct and how to use Wi-Fi Direct, mainly on Mac devices.Iphone Wifi Direct

You are likely to be familiar with Wi-Fi, which helps you surf online wireless. However, Wi-Fi Direct is virtually not so the same as Wi-Fi. It is mainly for data transferring and sharing, a function much more similar to Bluetooth.
Wi-Fi allows you to have access to the Internet on devices without a connection. There is no need to worry about your Mac’s slowing down. To achieve this function, you just need one router as well as a device able to be in connection to Wi-Fi.
For Wi-Fi Direct, you are required to connect to other devices instead of the router. You need to establish a connection between two devices that can support and enable Wi-Fi Direct. Then, Wi-Fi Direct allows you to share or exchange data between two devices.Part 2. Why Use Wi-Fi Direct?
About ten years ago, in order to share files and data with no Internet connection, Bluetooth was the best option for you. However, the speed of data transferring via Bluetooth was slow. Nowadays, the development of technology is proficient to solve this problem. There are many applications to help us do that, which even leads to system’s running out of application memory. Besides, Wi-Fi Direct was born. It is a better alternative. Also, some applications are designed with a powerful function to share files.
However, the reason why Wi-Fi Direct is introduced in this article is mainly because not all of these applications can establish a reliable connection during the transferring process. In contrast, Wi-Fi Direct depending on the connection between two devices is rather more responsible. It is indeed a function which can meet all your requirements.
It is quite easy to realize data transferring and sharing via Wi-Fi Direct by establishing a reliable connection between two devices with simple clicks. What is more, no wires are required and the main condition is that Wi-Fi Direct is enabled on the devices.
Although compared with the Bluetooth, the advantage of Wi-Fi Direct is that it can transfer and share data at a high speed. There is need to make the Mac run fast by cleaners. the time spent in sharing also depends on the size of your data and the running status of the devices.Part 3. How to Enable Wi-Fi Direct on Mac?
Wi-Fi Direct not only supports Android devices running 4.0 or higher operating system but also supports your Mac devices as well. Here are the steps in details for you to enable Wi-Fi Direct on your Mac.
Step 1. Open System Preferences on your Mac first.
Step 2. Next, choose Sharing.
Step 3. Then, choose Internet Sharing.
Step 4. Finally, select to use the AirPort.
By finishing these steps, a software base station will be turned on and it will be the one to serve as the central Wi-Fi hub. If necessary, you can rename it and enter the name whatever you like. Please be aware of that make sure to turn the function off if you do not use it.
Plus, you can connect your Mac device to some other device through Wi-Fi Direct. For instance, you can create a connection between your Mac and your TV. Follow the steps below and complete the connection.
Note: If you are not successful in connection, please check and confirm whether both devices can support Wi-Fi Direct or not.
Step 1. Turn on your Wi-Fi.
Step 2. Click on the icon again and search the options listed later.
Step 3. Choose Create Network.
Step 4. Follow the prompt.
Step 5. Then, a Wi-Fi network appears around your Mac, up to 25 feet.
Step 6. Find the network of your Mac device on the TV.
This is the way how you can realize the connection between your Mac device and other devices supporting Wi-Fi Direct. What you need to remember is that you are supposed to turn on Screen Sharing on your Mac at the same time along with the following steps:
Step 1. First of all, open System Preferences on your Mac.
Step 2. Next, select Sharing.
Step 3. Then, choose Screen Sharing on the left side of your screen.
Step 4. Enter your password and unlock the padlock if the padlock icon is LOCKED.Part 4. In Conclusion
You may be accustomed to sharing and transferring data with a network. Wi-Fi Direct seems to be kind of different from the previous regular way of sharing and transferring data before. Take it easy. Wi-Fi Direct is easy for you to master it. You can have a trial on this useful method in sharing and exchanging. Wi-Fi Direct will not disappoint you.
