Is there a way to automatize this process so I won't have to manually do it every time I turn on the Raspberry?
That's not needed if question #2 can be solved - and it can...
Is there a way to automatize it so that it will always recognize it must get the internet from the Wifi independently of the IP range given by the hotspot DCHP to this interface?

English is not my native language so please be patient.
When I don't know how to configure something, sometimes I let the system do it for me, mostly of the times, things works with default values. In this case, if you don't know the function of the pairwise and group parameters. You could check this Page or read below:

curl has no idea about 10proxy file, which is exclusive to apt package manager.
You should either specify your proxy in http_proxy environment variable, or using --proxy command line switch.
PS. HTTP error 407 means: "Proxy authentication required". Obviously, you forgot to specify your username and password, like this:
export https_proxy=user:password@...

On their own with nothing else, no they will not work in tandem. You would need to configure your networking to manually split traffic by application or use bonding as described below to have the kernel do it for you.
This is called Ethernet Bonding in linux , and is supported by the kernel (and thus all major linux operating systems). Generically the ...

You could try executing the following through the command prompt:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo rpi-update
sudo reboot
wait for reboot
sudo branch=next rpi-update
sudo reboot
wait for reboot
This should grab the latest firmware and updates to make your Pi be able to successfully find networks and connect to them....

I would say the vast majority of Pi users (and Linux users in general) don't bother installing anti-virus software.
There is a myth that frequently gets told along the lines of "Linux can't get viruses" or "No-one writes Linux viruses; they write for Windows instead". Those myths aren't true – viruses can and do exist for Linux distributions, although they ...

Reverse SSH is one option:
http://www.thirdway.ch/En/projects/raspberry_pi_3g/index.php
I'd prefer to just be able to straight up SSH, personally, so I'd try to get that working if I could. I suspect the issue that you're having is that you don't know the IP address the 3G modem is assigned, or that you can't get the modem to forward ports correctly to the ...

TeamViewer cannot be used on the Raspberry Pi at this time. They do not have a build for it.
You can install a VNC server, and that would be your simplest option. You would have no issues connecting on your LAN, however if you wanted to connect remotely, you would need to set up port forwarding.
An alternative to port forwarding would be to use a NeoRouter ...

Okay, from your question I'm assuming the following:
Latency is of primary importance
Quality (including framerate) is the second consideration
Compatibility (permitting a wide variety of client software) is irrelevant
Given that latency is king, let's first explore the differences between streaming JPEGs and H.264 and what they mean for latency:
When ...

You're going to have to change your default routes.
route del default
route add default gw [WAN gateway/Internet-connected router IP address] [interface]
For example: My internet router's IP address is 192.168.1.1 and it's connected to eth1 on the Pi.
route del default
route add default gw 192.168.1.1 eth1
Don't forget to enable IPV4 (or V6) packet ...

Mid ocean video communication can't be done for the $50 price range.
The Rockblock is for "short messages" meaning text or data under 340 bytes.
Videos are more like 1,000,000,000 bytes.
and just to give you an idea of how small that is;

@SteveRobillard answered my question in the comments. I will re-iterate it here for everyone to see clearly!

In the terminal type: ps aux | grep programname
ps = display currently running processes
a = show processes for all users
u = display the process' user/owner
x = show processes not attached to a ...

LAN almost certainly uses less power. This benchmark claims:
The built-in Ethernet requires 2mA
Pi 3 built-in Wi-Fi consumes around 20mA when idle
So that's a factor of 10x, when idle. You could expect significantly higher power consumption when the networking is active, although I suspect that the Wi-Fi power requirements would grow much faster ...

I don't see any reason why a properly secured Pi should be any less safe than a Windows machine; probably the Pi would be marginally safer.
Recent versions of Raspbian (e.g. Stretch) come with SSH disabled by default, which reduces the chance of remote intrusion significantly. Since you don't need remote access, that simplifies that problem massively—just ...

In order to control your pi over the internet you need to know what ip it has been assigned. Make sure you foward the right ports if the modem requires it.I would recommend ssh as a way to command/control the pi. As it is a more secure protocol. Other options to control the pi are:
You can set up a dynamic dns service on the pi (see here) and ssh into your ...

If you can browse from the Pi, then you should already have internet access from the terminal. The trouble is that you are using the wrong binary to test it. The firewall on a Mac blocks ping for security reasons. Most firewall do the same, or at least, should do. So ping is not a good binary to use to test network connectivity, in a secure environment. From ...

Judging from the output of ifconfig, your eth0 connection does not have an IP address assigned. There are 2 things you can do:
Make sure you have DHCP turned on on your router so that the Pi can get its IP address from the router when it boots up.
Manually configure a static IP address on your Pi by editing /etc/network/interfaces. See this article on ...

You can run x86 version of Teamviewer using ExaGear Desktop emulator
Install ExaGear Desktop (note that ExaGear isn't free and you have to obtain the license)
tar -xvzpf exagear-desktop-rpi2.tar.gz
sudo ./install-exagear.sh
Run ExaGear Desktop

"Can I install software like TeamViewer on Raspberry Pi?"
Yes, use a VNC server.
"Can I connect via wireless or LAN to the Raspberry Pi?"
Yes, and you can even do both at the same time.
"Can I connect an Internet key to a Raspberry Pi?"
Yes, if you mean a USB Wi-Fi dongle.

I had a problem with: lxde and DHCPCD is not running. I could correct by opening a terminal window and entering $ sudo dhcpcd, but this wasn't persistent across reboots.
When your system is starting, do you see:
[FAIL] Not running dhcpcd because /etc/network/interfaces ... failed!
[FAIL] defines some interfaces that will use a DHCP client ... failed!

What you could do is add/replace the repositories used by what I'm guessing is apt-get.
The file you need to modify is /etc/apt/sources.list. Open it up with your favorite editor and
You could completely replace the default deb entries (just comment them out to be safe)
Add the mirrors as new entries. I got them from here, hand-picked since some of the ...

I bet your DNS resolvers aren't configured. This is a common issue in Linux.
Add nameservers in the /etc/resolv.conf file by adding the lines below:
nameserver 208.67.222.222
nameserver 8.8.8.8
These lines add OpenDNS' nameserver (first line) and Google's DNS server (2nd line)
Alternatively, you could add the DNS servers in the GUI network manager by ...

I didn't want to leave this unanswered, so I found an old Pi B+ and an AP-Compatible WiFi dongle, and after trying a few times, finally found a way for this to work.
Please try the following steps:

First of all:
You MUST have an open port to connect to something. Anything else is like talking to someone's locked front-door instead of that person.
Reverse tunnelling:
This means that the Pi3 connects to something. Then orders that something to return traffic through that same connection.
This way you can talk to your Pi3 through that tunnel. Which in ...

It's hard to figure out what you want to do and why and knowing those might help give a better answer. If you really just want to learn to program with your pi, then all you need is the things you listed, power, and an OS to boot.
But then you mention wanting to network it with other machines that aren't connected to the internet. That's possible to do by ...

You can try to reconfigure WiFi. Just create a file /boot/wpa_supplicant.conf similar to this:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE
network={
ssid="wlan@hoeft-online.de"
psk="verySecretPassword"
key_mgmt=WPA-PSK
}
Of course you have to use your own settings for country=, ssid= and psk=.

The capturing is a job for tcpdump. As you have a bridge, you can capture on either side (eth0 or wlan0), but I would recommend the side where the device you want to monitor is attached.
If you have additional devices, you will want to filter. You can use either the MAC address or the IP address. You can also omit the filter to capture everything.

I'm running the same set-up--headless Pi with wicd-curses used to establish a static IP. To set up DNS I use these settings:
[X] Use Static IPs
IP: 192.168.1.207
Netmask:255.255.255.0
Gateway:192.168.1.1
[X] Use Static DNS [ ] Use global DNS servers
