Ubuntu :: Wireless Will Not Authenticate (After 11.04 Upgrade)
May 11, 2011
My wireless setup was working perfectly in 10.10 but after the upgrade to 11.04 all went wrong, i can see the device yes, and I can see the networks but when I try to connect it asks to reinput the password. And if I try with Wicd it says "bad password" the thing is, the password is the same i was using in 10.10 and it cant connect to an open network either. I am a bit new at all this, but as far as I know I was using p54 drivers in 10.10. in order to make the dongle work i hat to install "linux-firmware-nonfree"... tried to reinstall it, but the same result. Tried windows drivers too with ndiswrapper, and the same result again.

however, until this morning I had only been using my wired connection with no problems but when I tried to connect to my home's WPA secured wireless network, it just would not connect. The network manager sees the network and when I click on it, a window pops up asking for authentication. I enter the passphrase, but still it will not connect. I'm using a Lenovo X61 LAPTOP (not tablet).

We've got a Debian Lenny + FreeRadius and cannot seem to authenticate a wireless laptop.At this point, all I want is the users file entries to work, with ClearText passwords. Eventually we'll use LDAP but we want this up first with ClearText passwords and MD5.
1. FreeRadius installed, 2.1.10+dfsg-2~bpo50+1 from Debian Backports
2. AirPort v7.5.1, set up for WPA2 Enterprise, ip 10.10.10.75
3. Apple OSX laptop, 10.5.8
When running 'freeradius -Xxx' from the Debian cli I can see the authentication fail as though the OSX machine (or the AirPort router?) isn't passing along the password (from the FreeRadius cli run).Additionally, the OSX machine always prompts me for an SSL Cert to use, but with MD5 checkmarked as the only option in the 802.1x networking screen, this shouldn't be happening, making it more difficult to tell where this problem lies.The OSX machine keeps cycling through "Authenticating" and "Authenticating with MD5", and then settles on "AirPort has a self-assigned IP Address..." (meaning the laptop, not the AirPort wifi router)

I have an Acer Aspire 5920G laptop, which uses Intel PRO/Wireless 3945ABG wireless card. I upgraded from 11.3 to 11.4 using live upgrade and after the upgrade wireless internet became really slow. Now I'm back to 11.3. I experienced the same problem with speed when I was choosing Linux distro - first I tried Fedora and Ubuntu and both had the same problem, but when I tried openSUSE 11.3 it worked fine. With 11.4 Network Manager showed that signal is at 100% and it connected to router with normal speed, but when I tried downloading a file I got 30kB/s max, while I used to get 1,1 MB/s with windows and 11.3. I also noticed that right after boot I got decent speed, but it only lasted for less than a couple of minutes.
Since 11.4 should have better or at least the same driver as 11.3, problem is probably with configuration, but I am using NetworkManager, so I have no idea what could be wrong.

i recently upgraded to Ubuntu 11.04, but since the upgrade my wireless no longer works.
However the wireless driver (Broadcom 440x) is installed and enabled.
I don't know what to do, does anybody have an idea as to how i can fix this?

I tried to change my password through the Users and Groups dialogue, and now neither the old one nor the new one work. I tried to do it once, and it didn't do anything (the password was still my old password), then the second time I did it, when I went to save the configuration it wouldn't take my new password or my old one. Now I can't authenticate for anything.
A wicked backdoor I've noticed is that going into recovery mode offers you a root console without authentication. (Awesome, Linux, secure as all ****, seriously.) Is there any way to use this to set my user password without needing to authenticate?

I'm on ubuntu 10.4 and Cant seem to falsely authenticate myself with my AP. I am trying to break a wep key on one of my older linksys routers; It continues to say this:
Code:

Attack was unsuccessful. Possible reasons:
* Perhaps MAC address filtering is enabled.
* Check that the BSSID (-a option) is correct.
* Try to change the number of packets (-o option).
* The driver/card doesn't support injection.
* This attack sometimes fails against some APs.
* The card is not on the same channel as the AP.
* You're too far from the AP. Get closer, or lower the transmit rate.
root@kevin-laptop:/home/kevin#
I'm using an eeepc 701 it has an Atheros card and does injection. I have also tried it with backrack 4 and it works perfectly (it falsely authenticates with the ap and decrypts the wep key) I just cant seem to get it to work on ubuntu 10.4. Could it be a kernel issue? I found out that there is a bug in the new(er) kernel(s). If you use an older kernel (I used 2.6.31-14 which can be found here) and it magically works.

I have a TP-Link Atheros-based USB card: TL-WN422G. It's listed widely as being compatible, but I'm baffled if I can make it work. I'm running an ndiswrapper (XP-64) driver, and that seems to be loaded and recognizing the hardware correctly. The system can scan and correctly identify our network, and other nearby ones, but when the WPA key is entered (correctly, I've triple checked), the "Secrets" windows just keeps popping up and no IP is acquired. I've installed and tried to configure it with wpa-supplicant, all to no avail.
I've attached below list of various outputs that I've looked at.

I'm running Lucid Lynx. When I go into synaptic package manager and try to take updates, it says it can't authenticate some of the packages, including for example linux-image 2.6.32-27-generic. What is up with this?

Today I've found out that I cannot authenticate and use my ubuntu 10.10 partition as it doesn't recognize my password! The password is correct, I also tried to change the username in "root" but nothing changes. When I write it, it shows for some istants a black screen with words in it (so quickly that it's not easy to read) and then it shows me again the form to access.

I am having problems getting my wireless to work after upgrading from 9.10 to 10.04. I believe this is a driver issue as when I do a lsusb listing it shows up:
D-Link Corp. [hex] DWL-G120 Spinnaker 802.11b
however an ifconfig does not show any wireless cards. Only the eth1 and lo listings.
This lists my card as working with ndiswrapper, however I've had no luck. [URL]
I want to get this working again. 9.10 had no issues. Is it possible to revert back?

I installed a few media servers to stream something to my PS3 over the weekend, but now when trying to shutdown the computer, I'm asked to authenticate with a password since other users are still logged in. I installed quite a few programs over the weekend trying to get it to work, so I can't remove a specific one. Is there a way to see which daemons are logged in under a different session? Found it. It turned out to be mythtv.

I use Ubuntu in my office NIS environment and I can't upgrade the whole network to LDAP right. I upgraded to 10.04 recently and reinstalled the NIS client and associated packages, among other things.
I have set up my /etc/nsswitch.conf file so that passwd, group and shadow all have "files nis", I'm bound to the correct NIS domain and I can do "ypcat -k passwd" or "ypcat -k hosts" just fine.
Problem is that I can't log on or su to any NIS user, I just get "authentication failure". I've tried the same usernames and passwords on Red Hat NIS clients on the same domain and they work fine.

Ldapscripts seems to be authenticating oddly but I am not sure why. Running 'ldapadd' works without issue:
<code>root@domainator:~# ldapadd -D cn=root,dc=example,dc=home -W
Enter LDAP Password:
<CTRL-D>
root@domainator:~#
</code>
However:
<code>
root@domainator:~# ldapaddgroup test
>> 01/03/11 - 22:16 : Command : /usr/sbin/ldapaddgroup test
ldap_bind: Invalid credentials (49)
ldap_bind: Invalid credentials (49)
Error adding group test to LDAP
Error adding group test to LDAP
</code>
Here's various parts of my /etc/ldapscripts/ldapscripts.conf:
<code>
SERVER="domainator"
BINDDN="cn=root,dc=example,dc=home"
BINDPWDFILE="/etc/ldapscripts/ldapscripts.passwd"
SUFFIX="dc=example,dc=home" # Global suffix
GSUFFIX="ou=Groups" # Groups ou (just under $SUFFIX)
USUFFIX="ou=Users" # Users ou (just under $SUFFIX)
MSUFFIX="ou=Computers" # Machines ou (just under $SUFFIX)
GIDSTART="10000" # Group ID
UIDSTART="10000" # User ID
MIDSTART="20000" # Machine ID
</code>
/etc/ldapscripts/ldapscripts.passwd permissions are root:root, 0400 a
And I have quadruple checked my password is correct. Is there a way to print out debugging from ldapscripts so I know what commands it is generating?

I have a query regarding login to roundcube via dovecot ldap. I have installed and set up the openldap on Ubuntu Server 11.04 with the help of the following article [URL]. I have also installed Postfix, Dovecot, Dovecot-ldap and roundcube as the mail client. Then, I went on to test if I can login through roundcube. I received "login failed". I'm sure the dovecot is running fine as well as Postfix and openLDAP server. All I can find from the log was "auth(default) LDAP: Can't connect to server: localhost".

CLI upgrades and installations work just fine, as does Synaptic, etc.When I open Update Manager, it checks for new updates just fine, also, but when I click "Install," and the authentication window pops up, there is no field to enter the password. Closing out and retrying later, the authentication window pops up (again, without a password field), shakes back and forth rapidly, and disappears.The same thing happens with the software center. No error messages or anything with either of them, though.I've tried reinstalling the update manager from Synaptic, but to no avail.I'm running Ubuntu 10.10 64-bit (with the server kernel, because for some reason VirtualBox seemed to want it)

I am writing this using the 2.6.31-17 generic kernel after rebooting and selecting NOT to use the 2.6.31-18 kernel which was just installed. The newer kernel would not recognize/activate my Atheros AR2418 wireless adapter and, when I connected to the ethernet and did updates, there were no hardware drivers available. I haven't needed proprietary drivers since I upgraded to 9.04 and 9.10 works fine with older kernel.

New and ignorant here. I got a new System 76 netbook, love it, went to upgrade Ubuntu and since, have not been able to get wireless to work. Wireless light is off, no switches work to activate. Unit has no CD drive, can't get on internet without connection. Not sure this is the correct forum.

NOTE: My upgrade wasn't smooth. Now everything is extremely slow. However if I boot from the disc to try without installing, the connection problem is still there. There is an exclamation mark on the connection applet, right clicking shows that Enable Wireless is unchecked and unclickable. I've included outputs of common network commands which might prove to be useful.
Code:
[~] ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:33:60:f0:3c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

I upgraded from 9.x to 10.10. Under 9.x my wireless usb dongle worked correctly. After upgrade it does not. I checked the dongle on another machine and it works correctly. I inserted a usb memory stick and the system found it as a drive correctly. I assume from this that both the dongle and usb port are ok. The wireless device is a D-Link G122 A2 which is on the supported list (it ran out of the box on 9.x). The link light did not even come on. So I installed ndiswrapper and the windows D-Link driver (note that this was not needed in 9.x). Now the link light comes on and the wireless router is found but the unit will still not connect.
The log file entries on dongle insertion are as follows:
It appears that the problem is with wlan0 not being ready. If this is the case how do I make it ready?

I have an out-of-the-box Belkin G wireless router. I also have a Linksys USB adapter on a particular box. When I run the Ubuntu 8.10 live CD on that box I can see the router's SSID, I supply the password, and all is fine. I think that rules out any problems with the router or the ISP.
When I run the Ubuntu 10.04 on that same box I can still see the SSID but when I try to connect to it the DHCP fails. Checking the system logs I see the DHCPDISCOVER entries but no corresponding DHCPOFFER responses. So this seems on the surface to be a DHCP problem. To get around this I tried to edit the connection to use manually supplied settings. On the 8.10 system I supplied:
Code:
IP=192.168.2.200,
Netmask=255.255.255.0
Gateway=192.168.2.1
DNS=192.168.2.1
and again all worked just fine. But when I supply the same values to the 10.04 system it does not work. Even attempts to ping the router (192.168.2.1) fail. So if this fails then perhaps the problem is more fundamental than DHCP? I have tried searching the net for quite a while and found a number of similar problems, but clear solutions seem to be lacking (or I haven't come across them). One common suggestion is to blacklist the ipv6 module. I tried that and it seemed to have no effect. Since this worked so well in 8.10 and doesn't work in 10.04.

After upgrading from 10.10 I now have no wireless activity. Everything was great with 10.10 by the way. I have a dell inspiron 1520 with a Dell wireless 1390 card and broadcom 440x integrated controller.
I have seen other threads that are to complicated for me to follow, I would just love for my wireless to work and can follow basic instructions if anyone can help.
I just spent the last 6 days in Florida on business while the tornadoes ravaged my homeland in Alabama and turned alot of people on to Ubuntu. Everyone that walked past my laptop wanted to play with it and asked what it was.

I just updated my work laptop to Natty: perfect. My home server: perfect. My oldish home laptop: no more wireless. [I use wicd instead of Knetwork (or whatever it's called) because I want a permanent connection no matter the user]
I have a D-Link DWA-645. I get the whole stage: connecting, authenticating, etc... and bad password at the end. The password is correct (hasn't changed during upgrade). I also tried disabling WPA and it still won't connect. That's wlan2.
I also tried with an older PCMCIA card that _used_ to work on ubuntu 9, but stopped on version 10: a D-LinkDWL-G650. It doesn't even show up as wlan0 as it used to. I also tried with a USB-wifi DWL-G122 which has always worked on every version of Ubuntu [I don't normally use it because it's not practical on a laptop]. I see it as wlan1, but same thing: won't connect. Note that like with wlan2 I can scan for networks and see several around. For instance:
Code:
$ iwconfig
IEEE 802.11bg
ESSID: off/any
Mode: managed
Access point: not associated
Tx power: 20 dBm
Retry long limit: 7
[Code]...
[Edit]
Some more info: the access point works fine, I can connect with another device. The driver in use by Ubuntu is ath9k. Using KnetworkManager instead of wicd doesn't change anything.

This may actually (likely is) be two issues. But since both are happening since I did a reinstall (my term I think you all call it a upgrade 11.04-11.04) I thought I'd lump them together first.
My dell Inspiron mini has (of course) a touchpad and the wireless adapter is AR9285. The touchpad is not being recognized (although in a brief boot up into windows 7 it is fine there). I've tried adding backports, as I found in the documentation, but I'm lost. The wireless adaptor is being identified but the network is being shown as unclaimed. It too worked in Windows, so I'm fairly sure that although both worked fine after initial install, something was lost in the recent upgrade.
My problem is I don't know what to do for either issue next. Most of the documentation is on earlier Ubuntu releases (not 11.04) and I am not ready to backup in order to do a clean install right now. I have a new install I'm cleaning up and a clean reinstall that I just finished and am reloading backed up files onto. I'm hoping I'm missing something simple on this one...just once that would be really nice! So any quick answers? Do I need to split them into 2 issues and post elsewhere?

True or False: If you have a user on your Linux/Samba machine with a password, example:
User = Bob
Password = Password0
And Bob is on an XP computer, where his username is also Bob and his password is also Password0, is it normal for Bob to go to:
\SambaServer, double click on Bob's share (valid users = Bob only) and Bob get RIGHT in without being prompted?
On my prior setup, the user HAD to log in. If they wanted auto login next time with their credentials, they had to check "remember password." But now it's as if Samba knows who they are. It's very strange. What's the normal behavior? Must EVERYBODY authenticate with passwords, or if the Windows credentials are the same as Samba does it just somehow auto-detect it and allow them through?

I'm getting rather bewildered.
I followed these instructions to setup my wusb11 driver using ndiswrapper:
[URL]
But when I try to ifup the interface, I get:
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3
No DHCPOFFERS received.
iwconfig shows that no essid is assigned, even though I have specified one in /etc/interfaces.
Then if I go through the desktop gui Preferences -> Network to setup my wireless connection, /etc/interfaces does not seem to change but iwconfig then reports the essid is assigned.
Anyway, on my default taskbar there is a wireless icon. Clicking on that shows the wireless access points in the area. I see my own. When I try to connect to it, it prompts for my wep key. I enter the key, it thinks, and then acts as if I'd entered the wrong key.
Specifically of course, I'd like this to get fixed so that I can happily surf the net again, etc.
But I also I'm wondering why it seems that there is a disconnect between /etc/interfaces and Preferences->Network. If I type in a WEP key in the gui, I would think that it should appear in /etc/interfaces.
I'm definitely a Ubuntu wireless newbie, and not very experienced at Ubuntu anyway.

I recently installed Xubuntu (9.10) in my computer, but... I have been having intermitent hard disk problems, and so I decided to google a little and after reading this:
[URL]
I did use Synaptic to search for smartmontools and then install it.
Synaptic complained that it couldn't autenticate the packet, but I figured this was happening because... this is not an application supported by Canonical? I clicked and installed the packet (well, in fact, I *think* it has installed two applications, not just one).
Then later, I saw one of those arrows at the top right of the screen, and clicked it to install updates. Synaptic told me to update SUDO. Hmm... serious. And then even more: it told me that it couldn't autenticate it I stopped the installation and registered at these forums.
And more: before posting, I tried to reproduce the "error" (and again, stop before installing the "suspicious" SUDO update) but Synaptic now autenticated it troubleless and installed it.
Well, now I have a LOT of questions:
1. Where do I place this post?. Security?. Hardware problems?. Update and installation? (Linux noobiness?)
2. my hard disk?. I've read somewhere that an application called "fsck"
3. What may have happened with Synaptic?. Why wouldn't it autenticate a SUDO update?
4. Have I done something wrong?. Something unrepairable?
5. Can I trust the SUDO version that now I have installed in my system?
6. How could I check what has Synaptic exactly installed?. Is there any log file anywhere in my system?
