PostPosted: Mon Aug 25, 2014 5:07 pm    Post subject: (Solved) Cannot connect to mobile hotospot via wicd Reply with quote

For some reason I cannot connect to my Wifi hotspot on my Android mobile device. The computer that I am using is a dual boot Win 7 + Gentoo box. Windows 7 connects to the hotspot without any problems but when I try to connect using Gentoo GNU/Linux wcid gives the message "connecting" then 3 seconds later it says "disconnected". The mobile device is configured to allow all devices to connect (it is not blocking devices by MAC address or any other means). I don't see any wcid error messages in /etc/logs, and wcid does not show any error messages. Can someone please help me with this as I need a data connection when I am away from the office/home.

Hi

Sure that it's really "/etc/logs"? Not maybe "/var/log"?

In any case:

1)
you do seem to see the hotspot in wicd (e.g. in "wicd-curses", right?).
Apart from this I assume that you have configured correctly that particular connection in wicd (dhcp activated, wpa pwd is correct, etc...)

2)
When you "tail -f /var/log/messages" you should see some output coming from the module/driver of your wireless card when it tries to connect, then disconnects, etc....
No?

3)
Post here your "uname -a".
To let us know which kernel you're using.

4)
Post here your "lspci -k".
You'll see there which module your kernel uses for your network card.

5)
Post here your "modinfo <THE MODULE NAME OF YOUR NETWORK CARD>".
Example: "modinfo iwlwifi"

6)
Post here your "systool -m <THE MODULE NAME OF YOUR NETWORK CARD> -av"
This will show which parameters you're currently using for the module of your wireles card

Maybe by changing the module parameters the card will work fine (this is often the case in Linux - e.g. in my case the last time I had to deactivate 11n networking to make it work).

Thx

Opps, I meant that. now that I am in /var/log/ is see a wicd error log directory.

I hope so, it used to work before. I am not exactly sure what changed to make this connection not work anymore.

ok I was able to find this systool program in a package called sysfsutils here is the output.
Code:
systool -m iwlwifi -av
Module = "iwlwifi"

I don't think that there are any real "error messages" in your logs, right?

Btw., I forgot: could you please post here as well the firmware that you have?
("ls -lh /lib/firmware/*iwlwifi*")

You can try the following:

1)
Create the file "/etc/modprobe.d/blacklist.conf" if you don't have it yet and write the following into the file:
Code:
blacklist iwlwifi
blacklist iwlmvm

This will ensure that the kernel does not load automatically your wifi modules (maybe it's a problem of "timing"? Shouldn't, but you never know...).

2)
Create the file "/etc/conf.d/modules" if you don't have it yet and write the following into the file:
Code:
modules="rfkill iwlwifi"
module_iwlwifi_args="11n_disable=1 bt_coex_active=0 debug=0 fw_restart=0 led_mode=1 power_level=5 power_save=0 swcrypto=1 wd_disable=1"

This will load the module "iwlwifi" (when iwlwifi is loaded then iwlmvm will be loaded automatically if needed) and will disable the 11n, the bluetooth antenna and set the parameters in a completely different way than how they're set now.

3)
Reboot

4)
Doublecheck with "systool -m iwlwifi -av" that the settings match what we have set in "/etc/conf.d/modules".

5)
Check if it works 8O

The driver is compiled into the kernel and not a module. Still I tried it anyways.

Tried everything and I still cannot connect to the mobile hotspot. I don't think there is a problem with the driver as I can connect to other wifi networks without a problem. I think the problem has to do with some configuration error.

Then I'm sorry & I agree with your statement.
:cry:


Having a deeper look in the logs:
Everything seems to be working fine up to this point, right?
Code:
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.666683] wlp2s0: authenticate with xx:xx:xx:xx:xx:xx
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.668946] wlp2s0: send auth to xx:xx:xx:xx:xx:xx (try 1/3)
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.671775] wlp2s0: authenticated
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.672101] wlp2s0: associate with xx:xx:xx:xx:xx:xx (try 1/3)
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.675695] wlp2s0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x411 status=0 aid=1)
Sep  6 13:45:12 LIQUIDMETAL kernel: [138817.682440] wlp2s0: associated

But then after the stuff related to IPv6 dhcpd disconnects:
Code:
Sep  6 13:45:14 LIQUIDMETAL dhcpcd[12554]: sending signal ARLM to pid 12550
Sep  6 13:45:14 LIQUIDMETAL dhcpcd[12554]: waiting for pid 12550 to exit
Sep  6 13:45:14 LIQUIDMETAL dhcpcd[12550]: received signal ALRM from PID 12554, releasing


Maybe "disconnect" is the wrong word - is it shut down? (what's "ARLM"?)

Shots in the dark:
1)
You didn't configure by chance on your hotspot a whitelist of MAC addresses that are allowded to connect to it, or?
I'm really not sure if the access point will disconnect the device before it associates or between associating and assigning an IPv4 address to the device.
2)
Anything bad about IPv6?
Is the shut down of dhcpd a consequence of some IPv6 action?
Do you want maybe to try to compile a kernel without IPv6 support? Just to exclude that dhcpd is shut down because of some problems related to IPv6 (as the action happens after the IPv6-stuff).
Or maybe it's possible to disable IPv6 directly through /proc?

Mmmhhh...., don't know what else it could be... .

Cheers

I specifically set the device to alllow all all other devices to connect and not block anything

I guess I'll give it a shot, but I doubt it since my Win 7 partition that is configured for ipv6 works fine.

Since it had been a while since I've upgraded the kernel and went ahead and upgraded to the latest stable gentoo-sources and compiled it without ipv6 and still I am unable to connect to the wifi hot-spot but I can still connect to other networks without any issue.

So, this is the interesting part from your log. Your NIC associates with AP so the driver and password (if you have encryption) work fine. dhcpcd requests IP and doesn't receive any reply. Does your phone run dhcp server? Windows used to default to 192.168.0.* pool, maybe you need APIPA or static IP?
Also, have you tried with another dhcpd client? You surely have udhcpc, it's built into busybox.

I don't have udhcpc or busybox installed but I am willing to give it a try. How do you select which dhcpcd client Gentoo uses?

Assuming you are still using wicd it is wicd that selects which dhcp client to use. My /etc/conf.d/net contains nothing related to wlan0 as openrc is not involved in setting up the wireless on any of my machines. They all use wicd. In which ever wicd client you are using go into preferences and select which dhcp client you want it to use. I am using the kde client, preferences -> external programs. Mine is set to auto and it using dhcpcd.

The choices are auto, dhcdcd, pump, dhclient and udhcpc.

This is a bug in wicd. Lets look at the log snippet

Code:
Sep  6 13:45:13 LIQUIDMETAL dhcpcd[12520]: version 6.4.3 starting

dhcpcd starts, then solicits a DHCP lease AND a IPv6 router.
The IPv6 router replies 1st AND it has a RDNSS option which means you have a fully working IPv6 connection at this point, so dhcpcd forks to the background.
dhcpcd then continues to solicit a DHCP lease and all is good.

But wicd doesn't understand ANY IPv6, so it thinks that there was an error getting a working connection so it disconnects and tries again.

You have a few options
1) use dhcpcd-ui (either dhcpcd-gtk or dhcpcd-qt instead - https://bugs.gentoo.org/show_bug.cgi?id=522854)
2) instruct to dhcpcd to wait for an IPv4 connection (add waitip 4 to /etc/dhcpcd.conf)

I just checked and busybox is installed on my system (it must be a dependency of something else because I've never directly installed it). Anyways the wicd-gtk will not allow me to select udhcpc as the option is greyed out.

Just a guess, you might need to create a simlink like
ln -s /bin/busybox /bin/udhcpc
to use this option. Busybox by default does not create links to it's internals to avoid conflicts with fully-featured versions provided by their own packages.

Anyway,

seems to be worth giving it a try if you can specify custom arguments (from manpage)

Or add it to /etc/dhcpcd.conf as I said earlier :roll:

Thank you. adding waitip 4 seems to have done the trick. But what confuses me is that I used to be able to connect to my mobile hotspot without any issues. So something must have changed at some point that made it so that my laptop would not connect to an ipv6 address from my mobile device. Anyways thank you all for your help.

Two things did happen over the years ;)

1) dhcpcd grew IPv6 support
2) your hotspot grew a RDNSS enabled IPv6 router behind it

and the one thing that never happened was wicd evolving to match this.
