[SOLVED]Laptop Dell Latitude doesn't recognize Ethernet Adapter Linux Mint 18.3

Post by jsal01 » Mon Jun 18, 2018 11:16 am

Hello all.

I installed Linux Mint18.3 Cinnamon on a Dell Latitude E5550, and it doesn't connect to the cabled network. Later trying to see what was going on with the network I figured out it doesn't even recognize the Ethernet adapter.

Code: Select all

uname -a
Linux salazarusj1-Latitude-E5550 4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:32:20 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Any idea?

PS: The laptop is connected to a Dell dock (That thing that goes behind the laptop), but neither that ethernet port works, nor the one embedded in the laptop itself.



Thanks in advance to all!

Hello, jsal01.

Please, post the complete screen output of the inxi commandline

Code: Select all

inxi -Fxz
This will give us a few more basic technical details, which may be helpful in finding out what the cause is.

Regards,
Karl
--
P.S.: On my office notebook Dell Latitude E5470 the ethernet connection works without problems. Connected through the docking station as well.

Correct and weird, no ethernet adapter listed, only the wifi adapter.

Code: Select all

Network:   Card: Intel Wireless 7265 driver: iwlwifi bus-ID: 02:00.0
           IF: wlp2s0 state: up mac: <filter>
Would you have a chance of booting the notebook from the Linux Mint live system and find out whether the live system detects the ethernet adapter?

I have come across cases where users unwillingly had hit the keyboard shortcut which disables the wifi adapter. Yet, I do not know of a way to disable the ethernet adapter. - Of course, a technical defect can never be ruled out completely.
When has the ethernet adapter last worked correctly?

Maybe---check if the Ethernet adapter is enabled in BIOS.

I'll try this. I'll also check if the Ethernet adapter is enabled in BIOS.

Oops, yes, of course. - Has never occurred to me to switch off my ethernet card, because my notebook is firmly seated in its docking station while I am firmly seated in my office chair all day long. :oops:

Last time it worked correctly was on Windows 10. But I don't want to go back to it.

Hello, jsal01.

You had already posted your "inxi -Fxz" report as pure text and nicely readable in a post above. :)

does not add any new piece of information.

In particular, it does not tell whether you did as JerryF had suggested, entered the Bios setup of your machine and checked whether the Ethernet adapter had been disabled there.

In case you do not know how to enter the Bios and check the settings, then you will have to consult the Dell hardware manual.
On my Dell, right after power-on I press <F12>. <F12> will display a list of boot options. At the end of this list there is the option to enter the Bios setup.

This is what I did just to find out that the Ethernet adapter, named "First NIC" inside the Bios, can be disabled and re-enabled.

As the Ethernet adapter worked on Win10, it is imaginable that it has been disabled for whichever reason inside the Bios. So you should really check.

HTH,
Karl

Thank you, Karl.

I really don't know what I was looking for.

I just entered the BIOS from a Linux Mint live cd, and took pictures with my cell phone (I couldn't post anything because I was in the BIOS :P ). I will check that "First NIC" to see if it is disabled.

Regards.

Hi, jsal01.

As you took the photograph of "inxi -Fxz" while you used a Mint live system, the inxi photograph does hold a new piece of information, contrary to what I had said in my previous post.
The inxi report does not list an ethernet adapter. Means that the live system does not see the adapter, either. This means, either it has been disabled inside the Bios, or it cannot be detected, because it is defective.

Best regards,
Karl

@jsal01 and karlchen
I have a similar problem on my work Dell machine---Mint doesn't recognize the wireless card. It doesn't even show in inxi command.

@jsal01
I don't think karlchen saw all of the pics from the link you provided, just the first one of inxi -Fxz

From your pics of BIOS, it looks like your wireless device is enabled, so I don't think that's the problem.

If possible, use a wired connection, then update the kernel to a higher version than 4.10. Try one from the 4.15 series. You can update kernels from your Update Manager. After updating, have to reboot for the new kernel to load.

It turned out the Ethernet adapter was disabled in the BIOS, as you pointed.

I just had to "Enable" the NIC adapter in the bios, and when I rebooted the wired network worked.

Please disregard most of my previous post. I was getting my wireless and wired confused.

Glad that you got it resolved.

I admit that you are correct. I had missed the Bios photographs. :oops: A screen size of 1024x600 only (Acer netbook) does have its downsides. :wink:

Now that I have seen it, I can tell: the menu tree on Latitude E5550 (jsal01) and Latitude E5470 (my office notebook) look very very similar. Maybe remembering so will be helpful in a future case.

And to jsal01:
Thumb up. Congratulation on making your ethernet adapter work again. :)
