storage – Do I lose any photo quality with WiFi and AirDrop?

I am starting to develop more and more experience as an editorial photographer and I like to focus on current events around my city. That means that I find myself often submitting pics to Shutterstock from my car or other “mobile” locations to get my pictures approved as quickly as possible.

Right now I do:

  1. Panasonic Lumix DMC-G7 saving to RAW+Fine
  2. Connect my iPad to the G7 via the built in WiFi router; I can only download the JPEGs via this method, RAW cannot be done over WiFi
  3. Panasonic ImageApp on my iPad to transfer the images and save them to my iPad camera roll
  4. Use the iPad to review the images and decide which ones I actually want to submit
  5. Send the images to my iPhone via AirDrop
  6. Submit the images via the Shutterstock Contributor app

Does the above process introduce any loss of quality into my images? I have checked to make sure that the metadata is all there and it otherwise seems like the same image, but maybe I’m missing something.

How to fix iPhone X + iOS 13 Slow Wifi?

How do I fix slow wifi on an iPhone XR (iOS 13.4.1)?

The boss has an iPhone XR (iOS 13.4.1), and I have an iPhone 6 (iOS 12.4.5). The iPhone 6 gets 100% better Mbps throughput around my house. I have validated my router health and validated network setup on both phones. I have done all the reset/forget network cycling recommended by guides like this and this and this.

I measure the same performance percentage difference–iPhone 6 performs roughly 110% better–in all these tested scenarios:

  • 802.11 b/g/n 2.4 GHz network connection on both phones, simultaneously
  • 802.11 ac 5 GHz network connection on both phones, simultaneously (first screenshot)
  • Bluetooth off (second screenshot)

My test was:

  1. hold both phones in hand
  2. test average Mbps download speeds using Wi-Fi Sweetspots app
  3. average over ~10 seconds
  4. test 6 different spots around the house
  5. record results

Here are the side-by-side results of the latter two tests; left side is iPhone XR + iOS 13.4.1, right side is iPhone 6 + iOS 12.4.5

test on 5GHz AC network

Test with bluetooth radio off on both phones:

In both tests, “Spot 4” is standing directly next to the Wifi router.

hash – Breaking Wifi password knowing its length of 8 [A-Z] alpha (upper-case) characters using Hashcat

I got the WPA handshake, now it’s turn to crack the password using Hashcat. First, I wanted to make a wordlist of passwords (A-Z) the length of 8, but Crunch (the tool in Kali Linux) said it will take 1TB of storage that I don’t have available, so I gave up that way. Is there any way to generate passwords (example: ABCDEFGH) and delete them after its use one by one, during the cracking process?

How long does it take to crack the password with i5-3320M CPU using Hashcat?
Is there any other way you recommend?

vpn – How to connect to a wifi network that shuts down connections

Our school’s wifi shuts down after 12 am, and although we are still connected to the network, our connections are closed, and the computer says “no internet”.

However, we can somehow manage to stay connected to the internet even after 12 am if we use a VPN program, but after disconnecting, we cannot connect to the network again even using VPN

How does this shutdown system work and how can I connect to the internet even after it closes all connections?

networking – How do I get my modem’s IP address when using Google Wifi?

Occasionally I need to connect my ISP’s modem directly to initiate a restart.

Normally when I connect to my modem directly, I can either connect to the modem using the vanity URL provided by the ISP, or I can figure out the modem’s IP address, and connect to that (e.g. on macOS, option-click the network system menu icon, and observe the value for Router).

Problem is when I use Google Wifi as my router/access point, it’s no longer easy to find the IP address of the modem. Now the menu item shows me the IP address of the Google Router, and accessing it goes to a page that explains how to manage the Google Router.

How do I find the IP address of the modem which the Google Router is connected to?

When I came across some comments

I can redirect you to other pages without your interaction. Install key loggers. Heck if your browser runs activeX objects I could open a shell on your machine without your knowledge. That last example is rare these days but what’s not rare is tricking you into installing a shell for me, keylogging, session stealing, and redirection.

Or as I mentioned in my post, drop a crypto miner on your machine with the tool I wrote

Written by Anthony Russell in the comments of his answer.

So, this looks bad, obviously. What I want to know is how can I stop these attacks? Blocking javascript sounds like a good start, the original post also suggested to check my device for open ports (they did not demonstrate how to shut them though). What else? Is there a fool-proof way to prevent these sort of (virus injection? remote control?) attacks?

To be clear, I am not talking about logging. That’s a given when you connect to any network. Please also dont give any advice along the lines of “don’t connect to malicious networks”. There are reasons that I cannot switch away from a (possibly) compromised network.

What I’m most worried about is virus injection. But other attacks (like key loggers) mentioned above are serious concerns too. Just share whatever comes to mind. I’m sure other people will fill in the blanks.

Sorry if I sound like a complete noob. That’s because I am. Sorry in advance.

wireless – Kali: When I turn my laptop integrated WiFi card off it also turns my USB WiFI adapter off

I ask this because I want to use the USB adapter with Kali in VirtualbBox but it doesn’t get detected. I can connect to it on Linux but whenever I turn the integrated wireless card off it also turns the USB adapter off, like they’re sharing it, which is very weird as it never happened to me before.
