[SOLVED] Wifi networks are visible, but I can't connect

Post by tomato »

Hi, I'm trying to get my wifi working under LM 13 "Maya".
The wifi card has a BCM4306 Rev 2 chipset which needs the b43legacy firmware. I installed the firmware and I am able to see the networks but unfortunately I can not connect to any of these.

Your support is very much appreciated.

What does it do (or not do) when you try to connect? Do this from Terminal and post the output back. Let's see what driver is loaded, etc.

That all looks OK. Your driver appears to be loaded. What happens when you try to connect? Are you trying to connect on a wireless network that needs a password? Explain in more detail why you can't.

Hi,

I'm having the same problem on my laptop. I just used a wifi connection at Panera (wanderingWifi) and when i came back to my home network, the wifi is refusing to connect. Here is my output as per the question in this column:

ok i know this sounds stupid.. but you have opened the wireless connection , clicked on your router and put in the password?... I only ask as i have known people to try logging into the wrong router as they did not recognise their own in the list

1) I connect using the default network manager in MATE
2) Inserting required password
3) Network manager tries to connect (spinning circle)
4) After about 60 seconds there is a new password prompt

and so on...

I can't speak for pmpope but I definitely use the right router. It also does not matter wether the wifi is secured or not.
Is there a file that logs the steps of the connection process?

Are you sure your wifi is still enabled? Since you were recently able to connect on a public wifi make sure it still is. Right click on the network icon on your taskbar, ensure "Enable Wi-fi" is checked.

For tomato, I just noticed this on your earlier post. "Access Denied" from your lspci query. Since you can't connect even on an unsecured router I am thinking this is a permissions problem. At least it's a possibility.

That is just because I did run the lspci command with standard privileges.

EDIT:
Ideas for fellow sufferers (that did not work for me):
- blacklisting "bcma" and "b43" ("bcm43xx" is already blacklisted) in /etc/modprobe.d/blacklist.conf
- insert "b43legacy" in /etc/modules

So you can see the networks by clicking on the network icon? Can you try a "refresh"? Right click and uncheck "Enable WiFi". Then turn it back on. I'm at a loss here. Maybe unloading and reload the driver is the key. But it sure sounds as if it is something more simple.

I can see the networks around, I also get a password prompt, after that it tries to establish a connection and stays busy. After a while I'm again required to enter the password.

I also made some progress:
cat /etc/modprobe.d/blacklist.conf

Code: Select all

# 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.
blacklist bcma
blacklist b43
blacklist ssb
blacklist b43-pci-bridge
blacklist b43legacy
cat /etc/modules

Code: Select all

# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
b43legacy
lp
That is the base for the following:
1) run

Code: Select all

sudo modprobe -r bcma b43 ssb b43legacy
2) reboot laptop
3) laptop connects successfully to network (network manager shows b43legacy as driver; lspci output is no difference)
4) ..and loses the connection after about 20-30 seconds
5) After that it is not possible to establish a connection without rebooting again (things that didn't work: play around with modprobe; disable and enable wifi)

Here is the dmesg output of a successfull and non successful connection:

wlan0: authentication with 00:1c:4a:45:e1:69 timed out

I also attached a visual comparison (left side: successful connection; right side unsuccessful).

Edit:
wrote GRUB_CMDLINE_LINUX="ipv6.disable=1" in etc/default/grub and ran update-grub. IPv6 error is gone, but didn't change anything.

It looks like you're on to something here. I'm not sure why it shows deauthenticated but you're making progress. Maybe a network Guru will jump in and help.

Since
wlan0: deauthenticated from 00:1c:4a:45:e1:69 (Reason: 1)
could be anything (Reason 1 = unknown Reason), and it seems I'm back at square one, I'm going to abandon b43legacy.
Instead I followed the instruction of this guy and used ndiswrapper. Everything works fine so far.

That's great news that you tracked it down and got this working yourself (and without any real help). :oops: Give it a few days and if it's stable maybe you can put [RESOLVED] in the first post subject line. :)
