ip – Will an unconfigured ethernet port in Ubuntu 16.04 be connection local if it is connected to a connection local device?

If I connect a connection-local IP camera to an unconfigured Ethernet port under Ubuntu 16.04, does this port recognize the connection-local device and configure itself accordingly?

(I ask because I had a confusing network configuration problem and if it were true it would explain it.)

If so, can I prevent this by simply setting up a static configuration for this interface in / etc / network / interfaces?

If this is not the case, what else can lead to a port that is not explicitly configured in interfaces becoming local to the connection?

Problems connecting to the Internet (via Ethernet) after upgrading to Windows 10

About three days ago I had problems with my PC's Ethernet connection when it was still using Windows 7. After disabling energy efficient Ethernet, my connection was resumed short enough for me to download and install Windows 10. Since the update to Windows 10, I have not been able to connect to the Internet. The connection normally works for all other computers running Windows 7 and Windows 10. My PC is a self-made desktop with specifications that Windows 10 should definitely run. I can be more specific if this is an important detail.

I tried almost every solution I found online. I apologize for the length of the post, but I think it could be a good challenge for someone who has more knowledge than me. Here are the steps I've taken:

  1. Bug fixes executed: This returned a number of errors every time I ran it. After performing the troubleshooter, my internet connection would briefly display "Network: Connected", but after a few seconds it would return to "Network: No Connection". The errors would be (apparently random) between "" Ethernet "has no valid IP configuration (fixed)", "The default gateway is not available (fixed)" and "The connection between your access point, router or cable modem and the Internet is broken (detected) "- the last error was the rarest and most inconsistent after it was executed about 50 times).

  2. Renew my IP / DNS address: I tried ipconfig / release (successful), followed by ipconfig / renew. Every time I try to run / renew, I get a message that an error occurred while renewing the interface Ethernet: A connection to your DHCP server cannot be established. The request has expired. In response, I tried to run ipconfig / registerDNS. Initially, it was stated that the registration should be initiated and errors in the event viewer should be reported. The action did not change anything and I noticed several errors regarding the DHCP client in the event viewer that "your computer could not renew its address from the network … error 0x79".

  3. Resetting IP / TCP: I did both Netsh Winsock Reset (successful) and Netsh Int IP Reset. Executing the second command had about 15 to 20 lines of successful reset, but I think it can be an important detail that the last two lines said "Reset, Failed. / Access Denied".

  4. I don't have any external antivirus software, and turning off the Windows firewall didn't do anything.

  5. I completely reinstalled Windows 10, did a network reset and reinstalled the drivers of my network adapter. I still couldn't connect to the internet.

  6. I made sure that the power management setting for the network adapter did not allow the computer to turn off the adapter to save power.

If you've read this far, I really appreciate that you took the time to help a stranger online. The fact that I had a similar problem on Windows 7 where none of the above solutions worked, except turning off the energy efficient Ethernet, gives me hope that this problem could possibly be solved. I appreciate any advice / methods / information that anyone can offer and please let me know if you need additional information.

I believe that the errors associated with the ipconfig / renew and / registerDNS commands are the best place to start, but I don't have the knowledge to fix other errors. Also, I have not found a similar question online where someone has been troubleshooting and continuously "repairing" the connection with the same few error messages (but not providing connectivity).

WLAN – Cannot connect to WIFI. Can I use an Ethernet connection without driver installation? What can I do if it doesn't work?

I have installed Ubuntu 16.04. However, this was successful. Now the problem is WiFi. A connection to WLAN cannot be established. The drivers may not have been installed. It could be resolved if I could upgrade to Ubuntu 18.04. I would like to know whether I can connect the Internet via Ethernet in this situation or not. If not, what can I do to update the software?

I ask for your opinion to solve the problem.

I am currently switching from the boot loader between Windows 10 and Ubuntu. I want to fix GRUB and also create the boot menu. But I can't do anything without the internet right now. Please help and share your knowledge to solve the problem.

Networking – How can I get Samba to work over Ethernet?

Hello, I'm a newbie to Ubuntu. I'm sorry if this seems like a stupid question. I have set up Samba on Ubuntu 19.10 and it works fine, but I have problems with my WiFi adapter, which can be turned off at any time and is quite stressful to get it up and running again. I tried to solve this problem by installing an ethernet cable through my modem, but I don't seem to be able to see my shared files as I would have done with the ethernet IP address over WiFi without any problems. My smb.conf is below. please help

What can I do to get the adapter working?

sudo ifconfig enxc0335eee724f up

Time capsule – does Ethernet work with the Thunderbolt / mDisplayPort / Ethernet adapter?

I am trying to restore from the time capsule (via a new restore). Trying to use ethernet to make recovery faster.

So I'm using an old Mini Displayport Ethernet adapter that I have. But my MacBook needs a flash. So I have a flash to mini display port adapter.

Will this form of chaining work? I ask because it doesn't get IP and the router doesn't light up either (both cables have been tested by connecting the router directly to TC and it lights up so I know the cables and DHCP capability are working) A.

macos – Mojave + USB Ethernet adapter. kext wrong header? Lib statements?

After this question it should be possible to install a .kext for one of my USB adapters.
However, after disabling SPI and correcting file permissions in the kext directory, kextload fails and kextutil informs me that the various drivers were all created against the wrong headers. But I'm using Majave 10.4 and the ASIX driver is listed as compatible on the download page. I also tried the other text linked in the question above.

In particular, I cannot use the pkg installer for the ASIX driver either.

Network – My cable connection (Ethernet) on a new Ubutnu 18.04.3 LTS installation does not work. What is wrong?

I am using a laptop at home and there seems to be a problem that I cannot use my cable connection.
I recently upgraded to Ubuntu 18.04 LTS (kernel version 5.3.0-40-generic).

My wife's PC also has Ubuntu 18.04, and it works fine.
So it appears that the wired network adapter is failing. I think it comes from the driver.
I asked:

sudo lshw -C network

There was the file: / etc / network / interfaces content just::

iface lo inet loopback

I added the two lines:

auto enp0s31f6
iface enp0s31f6 inet dhcp

but it seems when I type the command:

sudo ifup enp0s31f6

it seems to be on DHCPDISCOVER forever.

What's happening? Why am I not getting an IP from my home router when it comes to a cable connection?

Maybe someone has a suggestion?
