[SOLVED] Intel(R) Centrino(R) Advanced-N + WiMAX 6250 AGN, REV=0x84

Bronze · 2017-02-05 23:13:37

I have a Dell N4010. It has wimax and wlan. I don't care too much about the wimax
I have to use wireless_tools (instead of iw) (WEXT compatible).

wifi-menu shows the WLANs that are within coverage. But when I enter the WPA password, the assocation/"connecting" fails instantly.
iwlist shows the following:

iwlist wlp3s0 scan

wlp3s0    No scan results

iwconfig wlp3s0

wlp3s0    IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=15 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

Use wpa_supplicant and post the errors.

Bronze · 2017-02-07 04:12:18

sudo wpa_supplicant -iwlp3s0 -c/etc/wpa_supplicant.conf

Successfully initialized wpa_supplicant
^Cnl80211: deinit ifname=wlp3s0 disabled_11b_rates=0
wlp3s0: CTRL-EVENT-TERMINATING

This command didn't return, hence the ^C

sudo wpa_supplicant -Dwext -iwlp3s0 -c/etc/wpa_supplicant.conf

Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
^Cwlp3s0: CTRL-EVENT-TERMINATING

This command didn't return either.

wpa_supplicant.conf contains

ctrl_interface=/run/wpa_supplicant
update_config=1

sudo wpa_supplicant -B -iwlp3s0 -c /etc/wpa_supplicant.conf

Successfully initialized wpa_supplicant

OK, so this last command had no errors ...

wpa_cli

But it's bedtime. Will report further tomorrow.

Your last wpa_supplicant was different in two important ways. 1) you ran it with sudo: wpa_supplicant must be run as root or with sudo, so this is good. 2) You added the -B flag, which means it doesn't show any of the output I was looking for. Try these:

sudo wpa_supplicant -iwlp3s0 -c /etc/wpa_supplicant.conf

sudo wpa_cli
> scan

> scan_results

This will go on the back burner.
I have a week long business trip ...

Thank for your help so far, will report back my findings asap.

Bronze · 2017-02-19 20:03:24

I ran the command as suggested, but after the last line of output nothing happens (no prompt). Is there other output I should provide?

$ sudo wpa_supplicant -iwlp3s0 -c /etc/wpa_supplicant.conf

[sudo] password for jlbakker:

That actually looks like it worked fine. Generally one would run wpa_supplicant with the -B flag as you had previously, however this hides all the useful output it tends to give it something goes wrong. Now when you run it without the -B flag, you get to see the output but it isn't -Backgrounded, so it blocks the terminal. This is normal.

So you can either A) open another terminal or B) run the wpa_supplicant command again with the -B flag, then proceed with the next steps.

Based on the history of this thread, I would have thought the next step would be to start wpa_cli and scan (run `sudo wpa_cli` then at the promp `scan` then wait for a moment for results, then `scan_results`). However, based on your last post it looks like wpa_supplicant already successfully associated with a network. Did you add your network to wpa_supplicant.conf? If you're not sure, please post the contents of /etc/wpa_supplicant.conf here or on a file sharing site you can link to. Also, please post the output of `ip a` after wpa_supplicant starts successfully (as it did in your last post).

My laptop has a wired connection: enp4s0

ip a:

wpa_supplicant.conf:

update_config=1

network={
	ssid="..."
	psk="..."
}

I am happy to report that ifconfig reported that an IP address was assigned after running "dhcpcd wlp3s0"!

How can I configure the laptop to get an IP address during reboot?

Having two IP addresses is somewhat cool (but useless as I have only one ISP) At least, I could move the laptop away from the ethernet cable.

Trilby · 2017-02-19 23:00:17

Glad it's working. I'd not try to have both the ethernet and wireless connected at the same time. But to get wireless started automatically at boot, you can enable the wpa_supplicant hook for dhcpcd (as described in the wiki) and then just enable dhdpcd@wlp3s0.service

That way dhcpcd will start at boot and fire up wpa_supplicant which will connect to any available network that you have a conf entry for. This is great for roaming between networks, just add a network= block for each one to your wpa_supplicant.conf and you'll be connected on boot to whichever one is available.

There are also various complex network management tools ... I have no idea what they are for
