Another wireless connection problem

Postby jerryd on Sat Apr 26, 2014 7:41 pm

Linux Mint forum,

Dell D400 Windows XP Home Edition version 2002 SP3 32 bit
Intel Pentium 1400MHz 2GB Ram. No PAE.

I'm trying out linuxmint-201403-cinnamon-dvd-23bit.iso to
replace windows.

I can boot from a flash drive and get an internet connection
with an ethernet cable but I can't figure out how to set up
a wireless connection.

I loaded Ubuntu a few days ago and had no problem with wireless.

Installed the driver with:
sudo apt-get install b43-fwcutter firmware-b43-installer
and that seemed to work.

Typing iwconfig yields:
lo no wireless extensions
etho no wireless extensions

Typing ifconfig yields:
Link encap Local Loopback inet address 127.0.0.1 Mask 255.0.0.0

I also couldn't find a way to see available local connections.

When I left clicked on the internet icon in the lower left corner
the only choices I got were Wired and Network Settings.

Where do I go from here?

check your driver if it has a kernel dependency.
which version of ubuntu were you using, actually i am not interested in the ubuntu version, but the kernel version of that ubuntu release.

Jahid,
Thanks for the reply.
I'm so new to linux I don't know how to find the answers to either of your questions.

I did find the preferences/network connections menu and set up a wireless connection
with my SSID and Mac address. Don't know what infrastructure, BSSID or MTU are.

I tried loading the driver for my wireless card again but got an error message saying
Could not resolve 'debial.linuxmint.com'

I'm running the OS from a flash drive so I think every time I shut down I lose everything
I've done.

Strange that when I tried ubuntu I had no problem with wireless connection.

If you give me something to try I'll get you the results.

Please boot into Mint, open a terminal, and enter the command -
sudo /usr/lib/linuxmint/mintWifi/mintWifi.py

Then boot the Ubuntu if you still have it, and repeat the process. It would help to compare the two.

Please post the results here. If you don't have the Ubuntu DVD or usb anymore, just post the Mint results.

In Ubuntu, you can get the kernel info with the command -
uname -a
Mint 17 v2 Cinnamon (64 bit), Quad core AMD A8-3870 with Radeon HD Graphics 6550D, 8GB DDR3, Ralink RT2561/RT61 802.11g PCI
Microsoft-free environment since 1996

austin.texas,

Thanks for the help. I've been to Austin many times.

The Ubuntu I tried was installed on it's own partition which
I have since removed. I don't remember exactly what version
it was but it had to be one that didn't need PAE.

I booted up linuxmint, opened a terminal and typed
sudo /usr/lib/linuxmint/mintWifi/mintWifi.py
got a message like no such command

I type cd /usr/lib and then ls, linxumint was there
I type cd linxumint and mintWify was there
I type cd mintWify and mintWifi.py was there

I typed mintWifi.py and got no such command

I haven't used Unix in almost 10 years but all these
commands are still in muscle memory.

the suspicion is that this Dell will have a broadcom card so if you copy and paste this command

lspci -nn -d 14e4:


and copy and paste back for Austin.Texas what you get:

(the command he gave you gives a working printout on our version of Mint)

Linux Mint forum,
Ran both commands and here's what I got relating to the wireless card.


lspci -nn -d 14e4:

802.11b/g Wireless Controller [14e4:4320] (rev 02)


lspci -v

my impression is that there are two different drivers: b43 and b43legacy

as here

https://help.ubuntu.com/community/WifiD ... y_firmware

so from this thread http://ubuntuforums.org/showthread.php?t=2214110 my sense is that the 14e4:4306 rev 2 needs firmware-b43legacy-installer

I would offer the view that the correct command; if nothing else had been installed; would be sudo apt-get install firmware-b43legacy-installer

my suspicion is that one should first remove the b43 with the command sudo apt-get purge b43-fwcutter firmware-b43-installer but that is only an observation

pdc_2,

I'm booting linuxmint off a usb flash drive and since it doesn't
have persistance it's like a new installation every time I run it.

I executed sudo apt-get install firmware-b43legacy-installer
and it completed with no error messages.

After the driver loaded I clicked on the network icon on the
bottom left and all is showed was "Wired Connection".
Where do I look for available wireless connections?

I opened a firefox browser to make sure there was a connection
and then unplugged the ethernet cable. Lost connection so
there was no wireless connection.

Linux Mint forum,

Went to this web site:
http://community.linuxmint.com/tutorial/view/354

and read about "Wifi on the Command Line".

When I typed in the "sudo iwlist wlan0 scan" command I got an
error message that said " interface doesn't support scanning"

There must be some way I can see if my wireless card is
recognized and if there are any available networks?

This shouldn't be this difficult.
