Dell Wireless 1397 with FreeBSD 11.2 RC3

[Vinay Sonwani]

Hi All,

So as suggested by Phishfry, Chris_H and SirDice, I made some changes in following files -

/etc/rc.conf
/boot/loader.conf
/etc/resolv.conf

now, when I hit ifconfig command, my wireless card is listed in available devices .
But I am still not able to access the internet through it. I am guessing that I may not have configured the wireless card correctly so I am attaching screenshots of ifconfig and other commands.

I am also attaching my router's configuration page.
Please guide.

Your wlan0 is showing "no carrier", which means your wireless network isn't associated and you therefor have no connection. Did you configure wpa_supplicant(8) correctly? Your ifconfig_wlan0 should show this too:

ifconfig_wlan0="WPA DHCP"

 

[Chris_H]

IMHO Since I see both IF' are showing no carrier. It looks to me, that the "upstream" isn't setup correctly.
Unless the directions, or your provider told you otherwise. Can I suggest that you change your current entry from 192.168.1.2 to 192.168.0.1, and see if that works for you?

Hi All,

As suggested by you all I made changes in following files -

/etc/rc.conf
/etc/wpa_supplicant.conf

Also, I asked my ISP to correctly configure my router. I am attaching screenshot for the same from Windows 10.

I tried with ifconfig wlan0 -v list scan and ifconfig wlan0 up scan commands to check available SSIDs but these commands did nothing.

Please guide me.

 

[Phishfry]

Your settings look OK. if ifconfig wlan0 up scan didn't scan then I suspect you are not loading the firmware.
Please show your /boot/loader.conf

One more thing, I notice in your ifconfig that the wifi is attempting to use Channel 165 with 802.11a.
But on one of your screens I see a SSID name with '2.4' in it.
Just for clarification, you have both 2.4 and 5ghz available to use from your upstream wireless access point? Channel 165=5 ghz.
Looks like I am seeing different SSID's for each frequency? Is that correct?

Also my /etc/wpa_supplicant.conf has a few extra lines. Not sure if they are required or not:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1

network={
ssid="nanoapu2"
key_mgmt=WPA-PSK
proto=RSN
psk="**********"
}

Hi All,

My /boot/loader.conf file contains following lines -

if_bwi_load ="YES"
if_bwn_load="YES"

I posted two screenshots for /etc/wpa_supplicant.conf in the previous post because I tried with only SSID in the first and SSID with frequency in the second (someone suggested me).

My router has only one band and that is 2.4 Ghz of frequency. Now If FreeBSD is searching for the WiFi on channel 165 which is 5Ghz frequency band then how to force it to search on 2.4 Ghz of frequency (that's why I wrote 2.4 Ghz along with SSID in the /etc/wpa_supplicant.conf file but, not sure if it will work).

Please help.

 

[Phishfry]

You are missing the firmware. Add this line to your:
/boot/loader.conf

bwn_v4_lp_ucode_load="YES"

.

how to force it to search on 2.4 Ghz of frequency

Well don't worry about this just yet.
When the wifi is not associated with an access point it is constantly scanning channels.
If you run ifconfig wlan0 over and over again you will see what I mean. Just keep your eye on it.

Your problem is firmware. It is not loaded until you do a scan. No scan=no firmware
In dmesg the device will look fine even without firmware.

So add the above line, reboot and try to scan again.

Hi All,

Phishfry, as suggested by you I added following line in /boot/loader.conf file -

bwn_v4_lp_ucode_load="YES"

but, it didn't work as well. The result is all same. Ifconfig showing no carrier.
It's searching all frequencies but not able to connect.


Please help.

Where you able to download the firmware?

What is the output of pkg info -l bwn-firmware-kmod

Were you able to use the msk0?

In all the pictures, msk0 show "no carrier", that means that no cable is connected to the laptop, check the connection
