Network Auto configuration Failed duing Debian Installation


Hi:

I'm right in the middle of installing Debian Jessie and I'm having to manually configure the network in expert mode because the installer is not seeing DHCP.

How can I find out what my ip address is?

Take an ip address somewhere in the middle of your local ip-range, from which you are sure there is no problem
eg
192.168.0.100
sub net 255.255.255.0
gateway is your router eg 192.168.0.1 or .254

or
192.168.1.100
sub net 255.255.255.0
gateway is your router eg 192.168.1.1 or .254

So check first in which ip range you are.
When you've installed everything you can sort out what caused your DHCP problem.....

If I go ahead with the installtion without configuring the network it could be even more difficult for me to set up later--
I don't want to do that.

I can't use 192.168.1.100 because that's close to the ip address of my router.

-:-Is it my public ip address is the one I need? -:-

I tried this cmd and instruction in this link but I need confirmation from someone that knows; Please-
The first cmd doesn't work for me.
http://www.unixmen.com/find-ip-address-dhcp-server/

Code:
grep -R "DHCPOFFER" /var/log/*
I don't want to put in the wrong address and pay for it later so I'll wait.
It can't hurt for the LIVE Debian DVD to just sit idle; least I don't think so--

I read through the Debian documentation and it does mention that the network can always be configured later but I'm trying not to do that. (had trouble with that in the past before)

That is a little strange. What is this device? Wired? Wireless? lspci ouput?

Can you confirm (if it needs it) that you have the required firmware for your network adaptor?

Finally, are you able to see the logs of the dhcp server (probably not but I think it's worth asking)?

You didn't happen to get a message about needing to install firmware? Is the debian installer recognizing your network device and loading the right drivers.

Thanks for you help: Evo2-

It's a brand new 1 TB HDD made by Seagate install on my desktop pc.
I had to install a wireless 802.11g/n on the mobo because my connection is wireless.
The router is down the hall.

I don't know if the firmware for the card is on the Live DVD/CD or not--

LSPCI:
Code:
Host bridge: AMD Advanced Micro Devices, Ic. Family 10h Processor Hper Transport Configuration
Host bride: AMD Advanced Micro Devices, Inc. Family 10h
Processor Address Map
Host bridge: AMD Advanced Micro Devices, Inc. Family 10h Processor DRAM Controller
Host bridge: AMD Advanced Micro Devices, Inc. Family 10h Processor Miscellaneous Control
Host bridge: AMD Advanced Micro Devices, Inc. Family 10h Processor Link Control
VGA compatible controller" AMD/ATI Advanced Micro Devices, Cape Verde PRO Radeon HD 77501
Audio device: AMD/ATI Advanced Micro Devices, Inc. Cape Verde/Pitcairn HDMI Audio Radeon HD 7700/7800 Series
Network controller: Realtek Semiconductor Co. Ltd TRL8188CE
802.11b/n WiFi Adapter
Ethernet controller: Realtek Semiconductor C. Ltd RTL8111/8168
PCI Express Gibabit Ethernet controller (rev 02)
I can't see the logs of the dhcp server because the desktop is ideling with the Live CD in the CDROM drive.
If I knew what cmd to run ( to find out the dhcp server) I could use my Vaio across the room to tell you.

Nope it's not recognizing my network card and it's not seeing dhcp.
Strange Debian found my wireless card on my Vaio but not on this desktop.

-:-At this point the only other option I have is to manually configure the network-:-

This is my desktop-

I have the mobo book handy if you need anything--

Then this is not a DHCP problem. If your card is not recognized then neither dhcp nor manual configuration will work.

I would only find that strange if they were identical chips.

So, what is this device? Eg what are the answers to the questions in my previous post?

According to this https://wiki.debian.org/rtl819x#Real...L8192U_devices you need firmware for the wireless card to work, and this tells how to install firmware during installation https://www.debian.org/releases/stab...h06s04.html.en

I can not confirm that this is the correct page for the driver for my WiFi card but I think I'm close-
https://wiki.debian.org/rtl819x#Drivers

Code:
lspci | grep -i network
Network controller: Realtek Semiconductor Co. Ltd. RTL8188CE 802.11b/g/n WiFi Adapter.
My WiFi card is a PCI card I installed on my mobo.

Should I install Debian and just and choose "do not configure the network at this time" ?

Hi,

the RTL8188CE is explicitly listed on the wiki page you link to. It says you need the firmware-realtek package.
You can download the firmware-realtek deb file and put it on a usb stick. The installer should prompt you for it.
Alternatively mount the usb stick on you already installed system and then install the deb with "dpkg -i".

Evo2.

Thanks!

I downloaded the driver ( firmware-realtek_0.43_all.deb for my WiFi card and it's on a usb pendrive now.

I'll try again and if I still have trouble with this part of the installation I can always install the driver after the installation.

I now have that firmware-realtek pkg on my usb stick.
I'll see if installer prompts me for it, if not I'll follow your instruction for the .deb pkg with the dpkg -i cmd-

I'll be back to let you know how it went-

The CDROM drive opened and the Installer told me that the installation was complete.

When I rebooted it booted into my Slackware distro not my fresh Debian installation.

I edited my LILO bootloader ahead of time (before I installed Debian) with:
Code:
other = /dev/sdb
label = debian
I installed Grub to my new 1 TB HDD that I just installed Debian on.
I'm not sure how to fix this but I found a solution for now.

Pressing F11 shows me both of my HDD's and I can choose Debian from there.
If I don't hit F11 it boots to Slack.

My WiFi is working!
