View Full Version : [ubuntu] crash took network connection away

Network and internet were working fine until a recent crash. Now the network is not being detacted. I can reach it through Ubuntu on a CD, another Linux on a CD or from a windows hard drive windows. It is only down on my Ubuntu installation (which I want to keep and use).

I believe the file that sets up the networking has been damaged. From the GUI I can go to the network manager and see that it is off. I then turn it on and it tries to connect, but fails. from the terminal I can type ifconfig eth0 and it will give me the network address. I can also verify the network is off but can not turn it on.

There is a self repair one can choose on boot-up. It goes through a list of files it tries to get on-line to fix various aspects of the system, and shows an error that it can't connect on each line of the repair process. So it can't fix the networking (or anything else) because it needs to be on the network to reach the internet.

So I think an important file is damaged and it can not set up the network detection at boot-up.

So if I only knew what file is kept in what directory, then I should be able to copy that file from my Ubuntu setup. I don't want to re-install completely because I am afraid I will lose all the programs and work I have done since I started using it. I have not yet learned how to back-up completely from withing Linux.

Hi, run these commands please

sudo lshw -C network

lsmod

lspci -nn | grep 0280

iwconfig

rfkill list all

sudo iwlist scan
and post the outcome here by clicking on new reply and click # and paste the information between the brackets.
Thank you

In order to do these I save them on a thumb drive, exit the CD version of Ubuntu which goes on line ok, re-boot in the hard disk. run the commands and copy the responses, save that on the thumb drive, and go back to the CD installation disc to go on-line sign back into the forum and post the results. The CD is the same version, it is the installation disc for this Ubuntu. So the setup files must be on it, if I only knew which ones they were and where they were located, the hard disk installation should come up ok as it did before the crash. That's the problem, I don't know where Linux puts the startup file, or which programs it calls that start the network.

I appreciate all the help.

Thanks - hope we can get it.

I appreciate all the help, and I am learning a lot from you about commands to re-start the network.
But, the computer was always working fine on the network/on-line when the power went off during a time when it was writing. That was 5 days ago, It has not worked since but always worked before. So turning it back on is possibly the problem - but probably not. When the power interruption came, the hard drive probably waved its little magnetic wand over something it should not - wiping out part of a a file or files. In which case, it won't be able to start until we copy a new version of that file into the directory where it is looking. I coukd surely be wrong but I'm an old troubleshooter from now antique systems, and that is where I would have looked in days gone by. I surely appreciate this education in Linux though. I looked at Linux in the late 1990's but was sidetracked by other work we were doing in those days. Surely do like Ubuntu now!!!

Code:

cat /etc/modprobe.d/blacklist.conf
# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

# evbug is a debug tool that should be loaded explicitly
blacklist evbug

# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd

# replaced by e100
blacklist eepro100

# replaced by tulip
blacklist de4x5

# causes no end of confusion by creating unexpected network interfaces
blacklist eth1394

# snd_intel8x0m can interfere with snd_intel8x0, doesn't seem to support much
# hardware on its own (Ubuntu bug #2011, #6810)
blacklist snd_intel8x0m

# Conflicts with dvb driver (which is better for handling this device)
blacklist snd_aw2

# causes failure to suspend on HP compaq nc6000 (Ubuntu: #10306)
blacklist i2c_i801

# replaced by p54pci

# ugly and loud noise, getting on everyone's nerves; this should be done by a
# nice pulseaudio bing (Ubuntu: #77010)
blacklist pcspkr

# EDAC driver for amd76x clashes with the agp driver preventing the aperture
# from being initialised (Ubuntu: #297750). Blacklist so that the driver
# continues to build and is installable for the few cases where its
# really needed.

Hi, I have consulted with lkjoel and we see nothing wrong with your files, so the only thing we can suggest is to reinstall I am sorry I know that is not what you wanted to do.
