Networking – Extremely slow WiFi speeds on Lubuntu 19.04?

Recently re-installed Lubuntu 19.04 on a new SSD because the old one failed. However, with the updated versions of Lubuntu I get extremely slow WiFi speeds. This was not a problem with the previous installation of 17.10. After some research, I found on 18:04 several posts to Intel Wi-Fi adapters. However, my lspci-sourced chipset is a Ralink RT5392 chipset, so solutions to Intel adapters did not help. Checking the normal Internet speed on other computers in the house is only possible on Lubuntu computers. Any suggestions?

EDIT: and now it seems unreliable to show the networks as available, sometimes the network icon disappears and needs to be restarted etc. Strange, because it's a fresh install a few hours ago with a new image from today.

Network – How to enable Wi-Fi on Ubuntu Server 18.04 without an existing connection

I have recently installed Ubuntu 18.04 on my device and run the setup without an internet connection. I do not have access to spare Ethernet cables, so it's up to Wi-Fi. I do not have an existing connection, so I can not install any packages. At this point, I have no idea what to do. My WLAN card is detected, but not displayed in ifconfig. I can not run iwconfig because wireless tools and wpasupplicant were not installed.
Here are some commands that give more information:

wifi – Bully and Reaver find nothing in any network

I've tried several different routers on my network and in my friends' network, but none of them find anything.

The command for reaver I'm running is:

Hacker -i wlan0mon -c 6 -b xx: xx: xx: xx: xx: xx -vv -N -L-S-K 1

The output I am receiving is down, it will keep showing "Receive Timeout". I tried to get closer to the network and even sat next to it, the same problem:

[+]    Switch Wlan0mon to channel 6
[+] Wait for the signal from xx: xx: xx: xx: xx: xx

The last two lines are repeated again and again. I also tried different parameters.

The Bully command I'm running looks like this:

bully wlan0mon -b xx: xx: xx: xx: xx: xx -c 6 -v 3 -d   

The output:

Sometimes Bully and Reaver also works (very rarely), but they never get anything, always pin not found. Am I doing something wrong?

I am fed up with the mistakes and have tried my own method. So I created a list of all 8-digit combinations 00000000 to 9999999Then I used Aircrack to bruteforce the text file, and it actually found the pin for both of my routers, for me and for my friend's router. I know that all WPS-enabled routers have an 8-digit pen and all 8-digit pens are listed in my text file. My problem, however, is that not all WPS routers use this pen, but may use a different PSK than the stylus. I bruteforce the .Cover File from airodump-ng,

In summary, these are my questions:

  1. Am I doing something wrong with Reaver / Bully?
  2. Can I get the WPS key by bruteforcing with my PIN list, even though the router uses a different password like "fj93jfo" instead of the 8-digit key and the router is WPS-enabled and not locked?

WiFi – Is there a way to configure iTunes on a Mac to enable another Mac to access its music collection?

Fortunately, on macOS there are some on-demand wake-up features, notably that a wireless keyboard or a mouse / wireless trackpad wakes up a Mac connected via Bluetooth.

The music scenario is apparently less user-friendly.

You can configure a Mac to share its music collection.

iTunes sharing settings

However, if you do not use the Mac with your music collection to put it into sleep mode, iTunes on another Mac on the same local network will not be able to see the music of the sleep-mode Mac, and there's no way to use the Mac with the Mac Activate music collection from the energy saving mode.

I want to confirm that this is as good as it gets. And yet, a Mac can be woken up by ssh, so it's no problem to ask for Wi-Fi.

Is there a way to configure iTunes on a Mac to enable another Mac to access the music collection? Is there a way to share the music collection via Bluetooth to accomplish the same thing by possibly forgoing video sharing because the bandwidth may exceed that of Bluetooth?

How can I permanently assign a static IP address to Wi-Fi or USB tether clients?

I use my phone as an extended display with x11vnc that works as intended.
The only problem is that I have to change the IP address on my phone's VNC client very often. Because of dynamic DHCP I suppose.
I use a Motorola g Turbo Lineage OS 7.1.2, rooted.

Can Android reserve IP?
Basically, IP address and host name are assigned depending on the Mac address.
Or something that does the same.

wifi – How can I test if all the antennas in Macs are connected and working?

I'm a technician repairing Macs everyday, and I test the Macs after repair (laptops and desktops).

So, what I do is a bump test of the Mac by signing in to macOS and testing everything: camera, keyboard, WIFI, Bluetooth etc. My doubt is: how can I test the 2, 3 or 4 antennas (depending on the Mac )? Model) are connected. I know one of them uses Bluetooth, while normally all of them add up to Wi-Fi bandwidth.
I can check the Bluetooth connection, but how do I check if all WIFI antennas are connected and recognized by the wireless card?

I thought I could do a WIFI speed test to test the download / upload speed of the router, but I've never used it. Any advice on a good WIFI speed test (if possible free)? Would this be the best way to check if all antennas are connected and the Wi-Fi card in Mac correctly detects all antennas?

Here's a post explaining how the antennas work (if that helps):
What is the difference between the three wireless antennas in MacBook Pros?


Any help very welcome

Wi-Fi – Prevents the phone from automatically connecting to a specific Wi-Fi connection without forgetting that connection

This feature I am looking for is available on MIUI-ROM and Samsung-ROM:

Enter image description here

Similar questions have been asked before:

This from 2015 has an answer only about Samsung and MIUI Roms.

Answers to this and this question (both from 2013) provide workarounds.

An answer to this question suggested using Wi-Fi Ruller, which unfortunately is no longer supported.

It looks like the questions are pretty old, and a simple, straightforward solution still needs to be found.

Does Wi-Fi affect the quality of images downloaded from the Internet?

No. Unlike analog files, digital files are always perfect copies, so the image can not be downloaded perfectly, or can be perfectly downloaded each time. The same applies to transferring between media (SD to HDD, pendrive, CD, …) or making copies.

Falsified copies are possible in some cases, albeit very unlikely, but they are not "inferior" but completely wrong (ie only half of the image and so on).

Apple with public Wi-Fi

Guys, when I was out and about, I tried using public Wi-Fi for my iPhone X. But I could not connect. Can anyone give me the reason for this and is this just for the iPhone or is this a problem for all Apple devices.
