In essence, my goal is to share the contents of the pi 4 screen over a
direct connection with a client device. Would this be possible?
Yes. You should make the wlan0 act as a wifi hotspot simple by this link:

Then, install your favorite VNC server on the raspberry pi. Take note that VNC Server is ...
To be able to setup Wifi on Raspberry Pi 4 B+ 4GB on Ubuntu server 18 TLS, you first need to get the name of the wifi card by showing physical components using the following command:
$ sudo lshw
in my case it was wlan0
Then navigate to /etc/netplan/ using the cd command the hit Enter
$ cd /etc/netplan/
use the command lsto list the files and ...
Thanks to @Ingo I got on the right path to finding my problem. I was not gettting a wlan1 because the correct driver was not installed. For the ASUS USB AC-56 I needed the Realtek RTL8812AU drivers installed.
From this thread, I was able to get the driver installed. Looks like @MrEngman's website has changed a little.

Or if you want to disable WiFi at boot, in your /boot/ (or /boot/firmware/ ) "config.txt" file add or uncomment the line "dtoverlay=pi3-disable-wifi" Note that this may be simply "dtoverlay=disable-wifi" in newer configurations.
To reenable wifi, comment out the line with a leading hash (octothorpe) symbol. (a "#")

I believe the problem is fairly simple.
You have an interface up, and establish a VNC connection across it. Then you try to make this interface part of a bridge. The first thing that happens is that the interface goes down. At this point, any connection across the interface is terminated. Then the bridge is formed, and brought up. At this point, the ...
As of 2020, the only thing that works for me is:
sudo ifdown --force wlan0
sudo ifup wlan0
Tested it in the following way:
Edit network ssid and psk in /etc/wpa_supplicant/wpa_supplicant.conf
Followed by sudo ifdown --force wlan0
Followed by sudo ifup wlan0
The tests were carried out on Buster-lite.
It has been tested atleast 5 to 7 times with time ...
At first, make sure you have configured the raspberry pi as a Wifi hotspot and check it on other devices. If other devices can connect to the AP of your raspberry pi and they get an IP address, follow this answer.
The apache.conf is the problem. Take a look at how the Splash page of a captive portal works!
Every operating system has its own different way ...
O help, just found out here what went wrong.
I've been having trouble with this too.
The answer was inside this command:
sudo wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d
I had placed the ssid and psk names between ' 'signs like ssid='my-network-ssid'
Changing it to "my-network-ssid" made it work right away.
And besides: raspi-...
At least your PI was able to get an IP address (192.168.1.51 as per your screenshot). So the radio link is working although it may not be perfect. Looks more like a routing issue than a hardware issue. If you type ifconfig you should see the same address now or you still have an issue. What is your /etc/network/interfaces file like ?
One thing: your output ...
For making remote ssh connection on raspberry pi 3B (os raspbian), it

You can do it by ifplugd package with filling the /etc/network/interfaces out. Follow this link to do that. You can be enabled to disable wireless networks automatically when a wired cabled plugged.

With iw dev wlan0 info you show that you are using:
channel 13 (2472 MHz), width: 20 MHz, center1: 2472 MHz
I remember that I had problems some times ago with connections using channels above 11. Since then I only use channels up to 11. I'm unsure if it also an issue for you because you have a link shown with iw dev wlan0 link but maybe there is a problem ...
I recommend trying to verify hardware is working: DHCP requires communication between the wifi adapter and the router, otherwise it can not be assigned an IP address. If you can confirm the wifi's MAC address was received by the router, then the wifi's transmit side is working.
If you had a second Zero-W with functional wifi, you could transfer the SD ...
There is a high correlation between Questions which state "I have setup a static IP lease" and XXX doesn't work.

I do not have the ralink rt2870 USB/WiFi adapter but here are some general ideas I have tested with the built-in WiFi device that you should also verify with your adapter. How to set the txpower on a RPi 3B+ I have shown at Restrict WiFi range of Pi 3b+. It also works on a RPi 4B.
If I do not have a valid /etc/wpa_supplicant/wpa_supplicant.conf file, I get ...
When I understand the objective correctly, the task is to capture data. For that purpose, you probably set your Wi-Fi interface into monitor mode and capture the frames being received.
If that is correct, fiddling with the Tx power (=transmit power) won’t help at all. You would either have to change the receiver sensitivity or the attenuation of the ...
What you have purchased isn't only an antenna to replace the built-in antenna (I don't believe that's possible), it is a complete new WiFi transmitter/receiver that can be used in addition to the built-in WiFi. If you do not need the built-in WiFi so just don't configure/use it. You can also completely disable it by adding this option to /boot/config.txt:
This error also shows up on the Raspberry Pi 4 platform if the firmware drivers are corrupt or missing. An easy fix would be to reinstall them.

"pi-ap" automates configuration of your Pi into a wireless AP. You can use the "pi-ap" scripts which are tested and proven to produce a working Pi wireless Access Point for comparative analysis with your own (broken) config. They're just a pile of bash scripts called in turn by the install.sh script. Things not obvious are well commented:
One possible problem may be the DHCP client. It will always get an ip address and network configuration (DNS server, gateway, default route etc.) on boot up. When the lease has expired the DHCP client may have a problem to renew it. If it cannot renew its ip addres then it will configure a link-local ip address 169.254.197.68/16 which does not fit to you ...

According to the commands output you have given about the configuration, bonding looks good so far. That all interfaces have the same mac address is due to bonding and will not confuse the fritz box router. Quite contrary it ensures that it does not sense the change of an interface on the fly because the mac address doesn't change. That's the trick of ...
You can set a special SSID (WiFi network) to the wpa_supplicant.conf:

I suppose you are using Raspbian. With my RasPis I have found that they tend to connect first to the 2.4 GHz band if both bands available. So first you should check if the 5 GHz band is seen by your RasPi. Execute this command.
rpi ~$ sudo iw wlan0 scan | grep -A5 'freq: 5'
It should give you at least one (ore more) outputs like this:
You don't tell us what error messages you get but you can try to restrict the connection to specific frequencies. In /etc/wpa_supplicant/wpa_supplicant.conf add a line with frequencies you want to use, for example (but use your own settings for country=, ssid= and psk=):
RPi 3B only has one antenna on board, so yes, it will be shared. Sharing is managed by the adapter firmware which is closed-source. Even if done right, it will not be as good as separate antennas.
You can get a USB dongle for either WiFi or BT (and use that instead of the built-in adapter) to get two separate antennas.
It's better if you ask this question on another SE Site which is related to security. Although, as @Modeset said, the IT man of the university can see which connected device tried brute force attack because of the packets statistic, etc. Because the raspberry pi shares the internet (I mentioned hotspot) and sends all wifi client's data as itself IP address ...
To verify your problem I have done a plain installation from scratch using the smallest image. Here is what I've done:
Downloaded Raspbian Buster Lite 2019-09-26 onto a PC with Debian operating system.

I see three possibilities as to what's happening here.
Somebody got unauthorized login access to your PI and used it to make attacks. I suggest checking for rootkits and the like.
Somebody is using the wifi to make attacks. It probably looks your PI because you probably are doing NAT. It could actually be an authorized user's compromised laptop. I ...
This is my answer based on how I've read your situation:
If your ethernet port got blocked by your IT sysadmin because it was being used for brute forcing SSH/some other malicious behaviour, then it's likely one of your WiFi users started to abuse your service.
It's not out of the realms of possibility that somebody complained they were getting excess / ...
