Linux Mint 18.2 x86_64 asking for WiFi password indefinitely - Card: Broadcom BCM43142 802.11b/g/n

[mgiagante]

Hi community!

I've done my research for almost a month but I can't find a solution for this.

Whenever I try to connect to my WiFi network, it starts to connect but then asks for the password once more. The password is indeed the right one since it works for other devices at home. My friend has the same problem, with the same Mint version and same wifi card.
The wired connection works correctly, it's just the wifi.

I'm pasting the command output I considered useful, but please let me know if any additional info is needed.

Thanks a lot for taking the time to read this.

wifi requires 3 settings to connect. The proper SSID, the encryption method used (WEP WPA WPA2 WPA2PSK) and the password. Have you done all of that? Also run this;

Code: Select all

iwconfig

[mgiagante]

I went to the network managing tab and the SSID for the connection looks good. It's the same as for my other devices: "Fibertel WiFi217 2.4GHz".
In the Wi-Fi Security tab, I see "Security: WPA & WPA2 Personal". Also, I've made sure the password is right by clicking "Show password" and it's correct.

I executed the $ sudo iwconfig and this is what I get:

lo no wireless extensions.

wlp7s0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=200 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on

In case it's useful, I took a part that keeps repeating in my dmesg output after I try to connect to the wifi network:

[ 1267.932042] ERROR @wl_dev_intvar_get :
[ 1267.932044] error (-1)

[ 1269.935351] net_ratelimit: 2 callbacks suppressed
[ 1269.935352] ERROR @wl_dev_intvar_get

And I also found this in with $ dmesg | grep wl :

[ 25.701973] wl: loading out-of-tree module taints kernel.
[ 25.701977] wl: module license 'MIXED/Proprietary' taints kernel.

[ 34.288592] IPv6: ADDRCONF(NETDEV_UP): wlp7s0: link is not ready

Do you need me to get the SSID / Encryption in any other way? Just let me know

Thanks in advance

Is this a laptop with a manual switch for wifi?

Is this a laptop with a manual switch for wifi?

This is a Sony Vaio - SVF14A16CLB, and it does not have a manual switch for WiFi as far as I know.

I've found instructions on turning wifi on/off in these docs but they're all done through software http://docs.esupport.sony.com/pc/SVF13N ... l3_22.html

Maybe a dumb question, but do you have broadcom-sta-dkms installed

Just tried $ which broadcom-sta-dkms and got that it's not there. Do I need it?

I've tried all the drivers Mint has offered me through the Drivers section in the menu.

[Spearmint2]

Broadcom is always a problem. You could get a USB wifi device that isknown to work with Linux. I use this one.

Check the description of apt show broadcom-sta-dkms

The BCM43142 is listed.

[mgiagante]

I didn't have it. I installed it and now the difference is that I can't see any wifi networks to connect to, and every time I enable/disable wifi, the whole system hangs for some 5 seconds.

This is what gets added to the dmesg logs when I enable wifi (nothing seems to be added when I disable it):

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service

Then get a newer version of bcmwl-kernel source

Code: Select all

wget http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb

Code: Select all

sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu3_amd64.deb

Reboot

[mgiagante]

I performed your steps and got this output:

I'm getting the initial results: Wifi re-asking for the password indefinitely.

You might have to disable IPv6 in Network Manager settings

Try linux mint 17.3. Does it work ?

I have the same problem, but with different make of USB wifi adaptor, the problem happened with 18.x+
