I cannot configure network with a new USB adapter in Fedora20

thakuma · 03-24-2016, 05:38 AM

My desktop is a dual boot of Windows7 and Fedora20. A lightning damaged my previous network adapter. With a new USB adapter I configured net in Windows7 but cannot in Fedora20. I tried nmcli commands but failed. I am adding here a few output.

[sonu@localhost ~]$ nmcli device status
DEVICE TYPE STATE
enp0s26f2u2 ethernet unavailable
lo loopback unmanaged

[sonu@localhost ~]$ nmcli con show

Hi...

Welcome to the forum

I'm not sure I can resolve this issue but out of curiosity, is this a ethernet or wireless adapter? Can you post a link to the manufacturer's product page?

Also, please post the results of...

Code:

lspci -nnk | grep -i net -A2

Code:

ifconfig -a

Code:

sudo lshw -C network

Code:

dmesg | grep -iC 3 "enp0s26f2u2"

If wireless, please also include...

Code:

iwconfig

There is also a script that will generate a lot of useful information here. Sounds like you will need to choose Method 2.

Regards...

i take it you are not aware that there is NO support for fedora 20 any more
it went END OF LIFE in June of 2015

currently fedora only supports fedora 23 and the soon to be end of life 22

please stay current and use a operating system that is supported

install Fedora 23

This is ethernet. Some of the commands is not giving any output. I am copying here as it was.

Hi...

Thank you for supplying the information that you were able, however, it's not enough (at least for me) to be able to help you.

EDIT: Mistakes were made on my part, please see my response below syg00's....

You might want to take John VV's suggestion and upgrade your version of Fedora or switch to another distribution, if possible.

Regards...

I'm surprised that lspci didn't return anything - certainly works as expected in F23.
You need to go through journalctl (or dmesg) to see what is happening to the driver load for that card. Start with that last command you were given - you mistyped it; should have a minus sign in front of the "iC".

Thanks for catching that, I totally missed it.

To the OP: I also forgot that this is a USB adapter, please try the command below, in place of lspci and post the results...

Code:

lsusb

Also, you're using Fedora, please just try just using...

Code:

lshw -C network

Another boo-boo on my part. My apologies.

However, I do agree with syg00 that it's quite odd that there were no results for the "lspci" command.

In my present OS I am heavily busy with a few installed softwares like kile, grace, gfortran. I am afraid if i go to higher version of OS right now and even after then I cant configure network then I will be in great trouble. So presently I take 'going to F23' as my last option.

Hi...

From what I'm seeing on Google, this is somewhat of a problematic adapter, however, it apparently is supported out of the box in Ubuntu 14.04.

What is your kernel version?

Code:

uname -r

I found this page which has a driver for kernel 2.6.32 but, as it was for ClearOS, I think the installation procedure for you will be different, if your kernel version is the same. Even if it is, I can't guarantee it will work.

Also found this thread that might be of help.

However, I think your best option is purchasing a more compatible adapter. Looking here, I noticed the words, "Works out of the box on Linux (Fedora 20)" under "Amazon.com: Belkin USB 3.0 to Gigabit Ethernet Adapter ..." which led to this page. I'm sure there are others available, too.

Regards...
