wi fi – How to transfer files from PC to Android via wifi without special software?

https://en.wikipedia.org/wiki/Android_11 came out in late 2020, when most home networks use wifi.

After searching for hours, I have been unable to find a built-in way of transferring files from my Windows PC to my Android Pixel (and ideally the reverse too) without downloading a special app from the Play store.

This is shocking to me.

Is it really the case that Android doesn’t natively support wifi file transfer?

(I’d rather not need to search for (and decide whether I trust) a third-party app. And I’d certainly rather not use a physical cable for file transfers like it’s 1990.)

wi fi – Internet access via external Wi-Fi adapter

Good afternoon, colleagues.

There is:

  1. Samsung S7, LineageOS 15.1, root, terminal, kalinethunter, drivers for AR9271 in kernel;
  2. WIFI USB adapter Alfa atheros AR9271;
  3. USB-miniUSB cable.

Internet access by a browser, not through the built-in wifi of the smartphone (wlan0), but through the external one (wlan1).


  1. turn on wifi in the smartphone settings;
  2. delete the memorized network in the wifi settings (so that the smartphone does not automatically connect anywhere via wlan0);
  3. in the terminal:
  • sudo ifconig wlan1 up (in any, kalinethunter, androidsu)
  • wpa_supplicant -i wlan1 -c / etc / wpa_supplicant / wpa_supplicant-wlan1 / conf (only in kalinethunter terminal, androidsu gives wpa_supplicant not found)
  • dhclient wlan1 (only in kalinethunter terminal, androidsu displays dhclient not found).

after that pass successfully:

  1. from the terminal kalinethunter ping and ping google.com;
  2. from the androidsu terminal – ping (if I add ip google.com to system/etc/hosts, then ping google.com also work);

But browsers (firefox, chrome) do not see the network. How can I go to the Internet with a browser (firefox, chrome) through wlan1, can you have ideas?

How to connect to wifi that has 14 meters away from my house

My neighbor has WiFi and she is willing for me to connect to their WiFi but there is a 14 meters distance between our house and their house. Is there a way for me to connect to their WiFi?

wi fi – GPS turns on every time WiFi network is changed

Whenever i change WiFi network, GPS just keeps turning on. I turned off GPS and change system settings permissions for every app, but it still keeps happening. Recent location requests shows that no apps have used that permission. Turning off google’s find my phone also doesn’t help. What is going on?

Device: Samsung Galaxy s10

Prevent the (wifi) from turning off and Disable the (airmode) for Samsung tab A 2016 using adb or anything else

Prevent the wifi from turning off and Disable the airmode for Samsung tab A 2016 using adb or anything else.

  • I want if I touched the wifi bottom on the notification bar to say "security policy prevents turn off wifi"

  • and the same with airmode in the notification bar to say "security policy prevents of use airmode"

     **Android 8.1.1 (Galaxy Tab A (2016))**

wireless – Trying to install wifi adapter driver on kali as it is not working properly on my kali virtual box

I am trying to install driver for Realtek 8812BU so that it functions properly on my virtualbox, because whenever I try to connect it to my kali machine on vbox it just stops functioning basically as soon as i plug it in, but works fine on my host. MY WIRELESS Adapter is an AIGITAL 1200M Realtek USB 3.0 802.11ac.

I followed all these commands:

sudo apt update
sudo apt -y install dkms git bc
git clone https://github.com/fastoe/RTL8812BU.git
cd RTL8812BU
VER=$(sed -n ‘s/PACKAGE_VERSION=”(.*)”/1/p’ dkms.conf)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu
sudo reboot

When I add the dkms it is fine and says it is added..
but after that
it shows this:

Kernel preparation unnecessary for this kernel. Skipping…

Building module:
cleaning build area…
make -j4 KERNELRELEASE=5.10.0-kali3-amd64 KVER=5.10.0-kali3-amd64 src=/usr/src/rtl88x2bu-5.6.1….(bad exit status: 2)
Error! Bad return status for module build on kernel: 5.10.0-kali3-amd64 (x86_64)
Consult /var/lib/dkms/rtl88x2bu/5.6.1/build/make.log for more information.

I dont know what to do or how to fix this stupid problem with my WiFi adapter.
If someone could please save me, i would really appreciate it.

networking – Create a new temporary MAC address to spoof free wifi?

I have a laptop with which I use to connect to a wifi. Normally, if I connect to some wifi, the laptop presents itself with its default MAC-address and I can display it using

ip a

where I can see the wifi device (wlp0s20f3), its IP-addresses and the presented MAC address (18:1d:ea:6d:be:00). This would be the MAC-address that I’d be using for people who have a wifi with MAC-address white list, etc.

Now imagine a Wifi, that limits the connection usage based on the MAC-address alone. To get around it, I could simply present a new virtual MAC-address once in a while and the Wifi would simply think it’s a completely new device connecting.

How can I do this in Ubuntu? With the ip command, possibly?

So far I found out I can create a new virtual interface using

ip link add link wlp0s20f3 address 00:11:11:11:11:11 wlp0s20f3.1 type macvlan
sudo ip link set wlp0s20f3.1 up

But how do I present it to the wifi now?

I want something I can set up temporarily and delete it later. Please include the commands to undo the setup as well. Thanks!

macbook pro – Wifi connection continuously cuts out

I have been having an issue I can’t seem to fix. The WIFI on my 2017 Macbook Pro keeps cutting out, about once every 10-20 minutes. When this happens I lose internet connection and when I click on the wifi icon in the menu bar it shows that my wifi is on and connected to my network, but my network, as well as all other available wifi networks, are greyed out and I am unable to click anything. Turning the wifi off and back on temporarily fixes the problem.

Here is a list of things I have tried so far:

Restart computer
Turn wifi on/off
Remove network and reconnect
Remove wifi service and reestablish
Rebout router
Factory restore of router
New SSID, new channels, new wifi password
Reset the PRAM & SMC
Updated the Mac OS to Big Sur (from Catalina)
Ran Wireless Diagnostics

Running Wireless Diagnostics initially finds nothing when the internet is working, but then when this happened it does detect a “Dropped Wi-Fi Connection”, stating that:

Your Mac experienced an unexpected Wi-Fi connection drop, which can be
caused by a combination of environment, configuration, and software

Provide the diagnostics report created in /var/tmp to an AppleCare
customer support representative for further analysis.

I looked into the logs, but am not really sure what I am looking at. And to make matters worse the applecare on this machine just expired.

Also worth noting that the network has been, and continues to work fine for all other devices (another macbook pro, two iphones, smart tv, etc.) and nothing major changed with the network before this occurred.

Any tips on what to try next?
