failed to connect

[phantom16]

so i just got to a new house with an existing wpa2 encrypted network. i logged in on pclos (the same one ive been using forever, updated just a couple weeks ago and everything) and tried connecting with the password, but every time, over and over (i have like 10x checked to maker sure it's the right password) it just keeps saying connection failed. i have restarted multiple times, and I havent changed any setting in the past couple days since i was connected at my old house no problem. i know its the right password, because when i log in on my windows 7 partition it works fine with the password, and this is how i am now on the internet.

I dont know why i can't connect. im running standard pclos 2011 with kde 4. this new internet is nothing funky, no static ip address or anything, just the name and a password, which works fine on windows, just not pclos O.o

I would delete the NIC connection in PCC and then recreate it to see if there is any change ....

[AS]

I would delete the NIC connection in PCC and then recreate it to see if there is any change ....

+1

additionally check dmesg for possible hints ...

run

Code: [Select]

iwlist scanning may be near you there is another router broadcasting on the same channel of your router ...  and at least you can see if your adapter see your wireless network ...

AS

[phantom16]

ok, so im hoping by "delete and recreate the NIC connection" you mean, go into PCC, click on the network and internet button on the left, and then click "remove a connection". then click the wlan0 device and remove it. then i clicked "set up a new network interface (LAN, ISDN, ASDL,...)" and go thorugh that. because thats what i did, but still to no avail...

i ran "dmesg", and skimmed through it, but i have no idea how to make any sense out of all that, and the output is more than twice as long as the maximum amount of characters allowed in a forum post, would it help if i posted all that?


regardless,  running iwlist scanning returns this:

Villa Gr_nspecht is the network i'm trying to connect to. there are a couple other networks that show up when i refresh my wlan0. one of them starts with "FRITZ" and the other isnt showing up currently (but it was a few hours ago, maybe the turned it off or something) but "villa..." is in the iwlist, so it seems my computer can see the network? it just wont connect for some reason...

Yes, the network is visible, it is using Channel 6, and reach your adapter. If the other routers in your area are using Channel 6 I would suggest to use a different Channel ...

Any info about your wifi adapter ? brand/model ? extract info from:

So it seems to me that they are all running on channel 6? do you think that might be the problem? and if thjat is, the problem with that lies in the fact, that again this isn't my house, im just renting a room, and the landlord has it set up, and i don't think they want me changing anything...
but if that is the problem, is there something else we can do to fix it? because it works fine in windows, maybe using the windows driver might be the next step? i dunno... :/

wireless network connecting and disconnecting a few seconds later is a problem i have and i have yet to find a reliable solution for.

do you know the module used to control your wireless card? What i do when i get this problem is deleting a file i am going to mention and then reload the module and it connects and stay up.

Try first to run the below command and then try to connect and see if it will stay up

rm   -rf    /var/run/wpa_supplicant/wlan0

[AS]

@muungwana,

03:00.0 Network controller [0280]: Atheros Communications Inc. AR9287 Wireless Network Adapter (PCI-Express) [168c:002e] (rev 01)
        Subsystem: Foxconn International, Inc. Device [105b:e034]
        Kernel driver in use: ath9k
        Kernel modules: ath9k

[muungwana]

Thanks AS,

OP, now try these commands(combined now)

rm   -rf    /var/run/wpa_supplicant/wlan0

modprobe -r ath9k
modprobe ath9k

Now try to connect and report your result

The last command shouldnt be necessary because the module get automatically loaded when i unload it(thats the behavior i am seeing there).

[phantom16]

ok, so after i do "modprobe -r ath9k" it does automatically connectt correctly, but them after a minute or 2 it disconnects again, and then if i try to reconnect it says connection failed, i have to do that command again, and then i will be reconnected for a couple minutes. any idea how to keep it from dropping the connection?

[muungwana]

just looked at one of your above posts and it says the connection quality is 28/70. The signal strength is too weak. Maybe the connection holds in windows because windows driver can sustain weaker connection than pclinuxos.

Try to move closer to the access point and see if you  can connect and hold a connection.

If you can, you can try moving the wireless network to another channel( start with 12 ).

A less crowded space could help with the weak signal.

[phantom16]

28/70 thats weird, unless that a different value than the percentage that shows when i just look at the connections in pcc and the bottom right corner? because there it says 52%, and my network at my old house had just about the same connection strength... :/
also, im not far away by any means, in my old house the router was in the basement, and about 5 rooms over, this new place i am directly below the router (its in the same room as me, but 1 floor above me me), of course that could be due to a weaker output signal...
and as it's not my router/internet, but the landlords, and it's locked in the office upstairs, and she doesnt want people to mess with it regardless, so i cant change the channel :/

and lately, i havent been needing to re-input modprobe -r ath9k, it just seems to be connecting and then disconnecting over and over again.... i dont know why the behavior has changed...

kind of a shot in the dark, but could the problem possibly be caused because the SSID doesnt have a normal english character in it (it's: Villa Grünspecht)

lol i have no idea why it's freaking out so much, i am not far away at all, and if it is a channel issue, then it is something that i won't be able to fix because i dont have access to the router :-(

[muungwana]

you are getting 3 different reasons for getting authenticated, 3,7 and 15.

according to mr. google reason 3 means the access point just went offline( or went out of range )

reason 7 means the wireless network tried to send packet before it was properly authenticated

reason 15 has to do with timing out when doing encryption handshaking.

I think the problem primarily comes from the unstable AP going offline temporarily and the difficulty in reconnecting is a secondary problem from a shaky driver and a shaky access point.

what kernel are you using? updating to a more recent kernel could solve the problem.

using window's driver could also be a solution.

I use b43 driver here and it disconnects every time it cant get a response from the access point within 500 ms. Increasing the time the driver wait before disconnecting if possible could also be a solution.

i have looked online to see if the driver can have its setting changed but havent found anything yet.

You may try to use a fixed "data rate", I have found that some adapter (notably my iwl3945), experience lot of difficult to connect in case of weak signals ... things improved for me:

from command line (temporary fix):

Code: [Select]

iwconfig wlan0 rate 9M
you should choose one of the rates available from your router:

                    ESSID:"Villa Gr�nspecht"
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 18 Mb/s
                              24 Mb/s; 36 Mb/s; 54 Mb/s
                    Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 48 Mb/s

note that you will loose this settings each time you will reload the kernel module.

To make the changes permanent:
Network Center -> (Select your wireless connection) -> Configure -> (scroll down) > Advanced
add the parameter: rate 9M to the field labeled: "iwconfig command extra argument".

what kernel are you using? updating to a more recent kernel could solve the problem.

[root@localhost ~]# uname -v
#1 SMP PREEMPT Sat Jun 4 04:13:21 CDT 2011
[root@localhost ~]# uname -r
2.6.38.8-pclos1.bfs
[root@localhost ~]#

i just updated it a few weeks ago, and its proving hard to do it now with the internet jumping in and out :-D

using window's driver could also be a solution.

i tried that briefly, but none of the options that were there said they would work with my device. ill try more on this a little later

so i just tried that, replacing the "9m" in iwconfig wlan0 rate 9M with all the speeds, and it still keeps dropping my connection... :/
