IPV6 was setup on local Ethernet network,is it the same method to be used for WiFi. also WiFi IPV6 has any dependency on wifi adapter.
No, the Wi-Fi stack operate on the data and physical link layer only. Moreover IPv6 operate on the network layer.
So at this level there is no difference between Wi-Fi and Ethernet.

I have an Android device connected to my macbook via USB. The Android device is connected to a WiFi network, the same WiFi network that my macbook is connected to.
I wish to sniff network traffic going to the Android device (using WireShark). I then wish to filter that traffic by the MQTT protocol.
So far, I have tried doing this by running adb shell ip addr from my mac terminal in order to get the ip address of the wlan0 network. I took the inet address and plugged the ip address into the display filter on WireShark like so:
ip.addr == 192.168.190.123
However, no traffic is showing on there, nothing through MQTT protocol or any other protocol, but the device is definitely making network calls.
I am incredibly naive to network stuff, so I really feel lost. Can anyone point me in the right direction?
Scenario: I want to have an iOS device connect to a LAN that has no upstream Internet connection, yet still retain and use its cellular data connection.
Theoretically, it strikes me that the iOS wifi NIC and the cellular data NIC are similar enough to dual NICs in a PC that I should be able to set up routing such that any request to, say, 192.168.. goes through the wifi connection, and any other request goes through the cellular data connection.
I did a test to see if both NICs are active when the iOS device is connected to wifi by the following steps.
Ensure that my iPhone's wifi is off and that I have a good cellular data connection.
Disconnect my wifi router's Ethernet cable to my cable modem.
Connect my iPhone to the wifi router.
Use another iPhone that's connected only via cellular data to create a game of Words with Friends.
As soon as the other iPhone completed the first move, my iPhone received a notification that there was a new game to play.
This confirmed that the cellular data connection was indeed alive and well enough to receive push notifications despite the wifi NIC's being connected.
The question becomes, then, can an app programmatically connect to a given wifi network, set the cellular data network to be the default route, and route any requests to, say, 192.168.. to go through the wifi network?
I know this post is old, but I happen to have done some work on using multiple network interfaces on iOS.
My experiments showed that accessing via hostname results in iOS choosing the network interface it wants to use, and not trying any further interfaces if the host cannot be resolved.
If you know the DNS Server IP address for any Ethernet/WiFi based network, you can send a DNS request yourself, convert the hostname into an IP address and access via IP address. iOS will then use the correct interface.
My guess is, that if you have the private class IP address space accessible over both connections, there's probably nothing you can do to specify which network interface should be used.
Is there a way to use a wireless router as some sort of Access Point + Repeater?
I have a LTE Box with a SIM Card that has a build-in router which is pretty shitty.
I now want to connect a proper router to this LTE Box (via WIFI, since the LTE Box has no LAN Port) to get internet access and then connect only to the router (via LAN Port, since I don't trust in WIFI).
The answer depends on your W-Lan Router.
Some devices got a function called WDS -> Wifi Distributed Service.
You need to specify the signal and the login data for the wlan router who should distribute the original signal.
Is it possible to set up a simple client server application to send text and other data over a wireless network in a LAN situation between two computers without setting up any network shares? By just knowing the IP address?
Yes. WiFi is just like any other network, you use TCP/IP over it to implement any network protocol you like.
I got a WiFi router connected to my PC.
What I want is to send from another device some data to my PC through the Wi-Fi adapter.
Program on the device is developed using EVC++. The one on PC - on VC++.
EDIT 1:
PC has an IP address.
Another device s IP is set at program execution. I mean WiFi IP address. And then connection to WiFi router is proceeded.
EDIT 2:
What if it uses an ethernet and wifi together?
How should I make a connection through WiFi?
WiFI is no different to usual Ethernel network.
So you just usually find out IP of other computer (in config/ask user/DNS), establish usual TCP/IP connection and send data on.
