Configuring wifi in debian jessie

Postby dev?l » 2017-03-12 12:02

Hi guys this is an update on the previous session installing Debian once again. I must confess i really like this challenge especially the steap learning curve. However after i have everything up and running i will post here details of what i did and at what time and some resources where i digged to learn few specs. The previous post were about the User interfaces. Now i have that fixed.

Another scenario kicked off from there. I cant configure the wifi settings. I looked at this tutorial link:
http://www.debianuserforums.org/viewtopic.php?f=9&t=388
https://wiki.debian.org/WiFi/HowToUse

and then edited my sources.list file like this

Code: Select all
nano /etc/apt/sources.list


and now the sources.list file looks like this:

Code: Select all
deb http://security.debian.org/ jessie/updates main contrib  non-free
deb-src http://security.debian.org/ jessie/updates main contrib  non-free
deb http://ftp.us.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.us.debian.org/debian/ jessie main contrib non-free
deb  http://ftp.us.debian.org/debian/ jessie-updates main contrib non-free
deb-src  http://ftp.us.debian.org/debian/ jessie-updates main contrib non-free


then i ran:
Code: Select all
su
apt-get update


but it is returning unable to fetch errors like this:

Code: Select all

Ok in the error msg i inderstand that part of the errors here is this.

Code: Select all
ftp.us.debian.org


Ok i changed in the sources.list file this code:

Code: Select all
[color=#FF


deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Binary 20170116-23:44]/ jessie main


to this:
Code: Select all
deb cdrom:[Debian GNU/Linux 8 _Jessie_ - Official Snapshot amd64 LIVE/INSTALL Binary 20170116-23:44]/ jessie main contrib non-free


and then its returning this error:

i realised after i restarted the pc immidieately after grub2 menu, i saw something like this:

Code: Select all
iwifi 8000 ....the rest was too quick


I dont know if i am doing something wrong. It will still return the same error. Perhaps would someone try helping out here. At this point i am not sure what to do.... Thank you in advance and oppologies for disturbing the peaceful sunday...

It's okay, you need to complete your wifi setup before you try to use apt. The sources.list doesn't configure wifi, it configure package management, which requires a network connection, or a local source.

Just do the wifihowtouse steps for your setup until you get ping working. It's basically ID the hardware, install the firmware, then configure.

After you get ping to some basic http address resolved, then you can edit your sources.list and use update and other apt commands. Go slow, there are a lot of different ways to do it because of all the different hardware out there, so advice for one type of wifi device won't work on all of them.

@bw123...Thanx man...and apollogies for not being able to reply on time...I read your post but then i thought to get back here with no empty hands.... :D ...Your simple words did actually serve like a tutorial really....I went and manually downloaded the non-free firmware and then mixed it with b43-fwcutter_amd64 and then all the magic happened....Right now i have a very strong wifi on this workhorse.... I realised Debian is quiet different from most distros...
During this few weeks i have learnt a lot of things from these distros than i ever did for the last three years....Thanks for for your advice it really helped...
After i got the network-bar up, i did not even need to do any
Code: Select all
apt-get update
command. All the updates just automatically sprang up for themselves....Hmmmm am very happy now...Once again thanks bro....everything is fine now....
