Ubuntu Networking :: Wpa2-aes - Can't Get A Stable Connection
May 16, 2010
Does anyone have a way to use this type of encryption? I have read many posts but have not gotten a solution yet. I am trying to get this to work at a friend's house. I know the SSID and the super-long ascii code (with symbols?). gnome nm and wicd have been useless. I have been connecting to my school's wpa2 using wpa_supplicant + dhclient directly, so I tried adding it in there:
network={
ssid="name"
scan_ssid=0
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="horribly long thing"
}
What happens is a string of connects and then immediate disconnects when runnign wpa_supplicant. It says "CTRL-EVENT-DISCONNECTED - disconnect event - remove keys" then starts all over. Can't get a stable connection but I must be close?

I don't know where to put this, or even what I'm looking for.
I've tried for 6 hours today to get my WPA2 wireless to work as a static IP on my laptop to no avail.
Basically I put things in correctly (at least according to that thread) but I get no interent. When I restart I get the correct IP address but no internet pages will load.
The network monitor I have on my panel shows that it is trying to send and receive information, but I can not get my pages to load.
I'm desperately in need of help, but I really don't know how to even ask for it correctly.
But to start here is my interfaces file (one config of about 15 I've tried).
Code:
auto wlan0
iface wlan0 inet static
address 10.42.32.113
netmask 255.255.255.0
[Code].....
My router is a linksys WRT54GS. My wireless is set up as WPA2-Personal with the "algorithm" as TKIP+AES.
Its like it wants to connect and gives me an IP. But I just don't get any real web data.
I've restarted and tried restarting just the network.

I am running Ubuntu 10.04 on a PackardBell notebook and have just got an Orange Livebox 2 for broadband connection(after years of dial-up as no adsl in my area).I am trying to connect via WiFi to the Livebox to configure, but neither NetworkManager nor Wicd will connect. NM sees the Livebox but simply fails to connect after trying; Wicd says "Bad password".The WPA2 password I have entered is definitely correct, and I have connected without any problem from an AcerOne under Linpus.I have also tried to connect using Wicd and an ethernet cable, and this doesn't connect either, returning "Connection Failed: Unable to Get IP Address"

I've installed F10 on my laptop since few days and I'm facing an annoying networking issue: the network connection seems to work well when, suddently, it goes down for a while, and then come back.This happens with both wired and wireless (Intel PRO/ Wireless 3945ABG) connection.

I'm relatively new to Linux. My netbook ran updates yesterday for Ubuntu and now I am unable to reconnect to wireless network connection. I am using WPA2 encrypted security. I am able to connect via wired LAN. Also, when I went to connect using USB mobile connection, I get an error "unable to mount location". I get the same error if I try to connect my external CD drive. I am using Ubuntu 8.04 with Gnome desktop (2.22.3) on a Dell Mini 9.My wireless device is using Broadcom STA Wireless driver for an 802.11 wireless card.

NetworkManager is a powerful tool for setting up a wlan connection, especially if you connect the laptop to multiple access points. One drawback is that the user accounts must be given access to the pass
phrase. Another is that there is no wlan connection in run level 3, because nm-applet is an X application.If you connect to the same access point all the time, e.g., your own wireless router, a permanent connection via ifcfg might be more convenient. It is controlled by root. All user accounts have wireless access without knowing the underlying details. Further, there is a wireless connection in run level 3. After a lot of trial and error and Google searches, I was able to put together this guide by splicing together one step used in Slackware (from Alienbob's web page) with other steps outlined in this online article http://home.roadrunner.com/~computer...hwireless.html.
It is assumed that the appropriate kernel module for the wlan card is installed and that
$ iwconfigshows a viable wlan0 interface. We are using DHCP. (If using static IP, edit ifcfg-wlan0.)The following steps work on a Compaq Presario F756NR notebook with a Atheros AR242x 802.11abg WLAN card using the ath5k kernel module (without madwifi). I am using 64-bit F12. All commands are executed as root.1. $ yum install wpa_supplicant dhclientProbably already installed, especially dhclient. If so, skip.2. $ cd /etc/sysconfig && vi wpa_supplicantInsert the following lines:
INTERFACES="-iwlan0"
DRIVERS="-Dwext"
OTHER_ARGS="-f /var/log/wpa_supplicant.log"

I'm using Debian 8 with GNOME 32bit. I installed a driver with ndiswrapper for my old D-Link DWL-G650M.
If i using the default network manager to connect with a Free wifi the connection works fine. But if the wifi have the password the connection doesn't work.
I. using my phone Android to create the Router-Wifi like this:
SSID: AndroidAP5
Password: BillyBob
Encryption(the one allowed): WPA2 PSK
With network manager gnome is impossible to connect. I changed in setting the password type with WPA2 but the system doesn't connect.
I tried to connect manually and i updated the file /etc/network/interfaces as the follow:
Code: Select allauto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid AndroidAP5
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk 18[...]
After this I tried to execute the follow command :
Code: Select all/etc/init.d/networking restart
And the system returns:
Code: Select all[ ok ] Restarting networking (via systemctl): networking.service
but nothing else happens. The internet connection doesn't work. The Android phone not detect PC connection IN.

I've been using network-manager-pptp to create a PPTP VPN connection in my Ubuntu virtual machine for a while now, but I have constant problems with random disconnects. I don't know what the cause of the problem is, but I suspect that network-manager-pptp is not the most well-written piece of software around...
Is there another way of instantiating PPTP connections in a more robust manner? The same PPTP server works reasonably OK with Windows 7 (some disconnects, fewer than in Ubuntu, and Windows has an auto-reconnect feature).
I read some guides on using the pptp command, but they all seemed pretty low-level, messing around with ppp. I never found the time to figure out how it all was supposed to fit together. Has anyone accomplished what I'm trying and is willing to share the knowledge?
EDIT: Tried kvpnc, and it seems the stability is more or less the same as network-manager-pptp. The error message is "Modem hangup".
To clarify, I understand that the connection can go down, but I want to be able to reconnect automatically when disconnected.

I have a Toshiba hard drive that has a few partitions on it. Recently, when it is plugged to the computer, the connection is not very stable. Usually I have this Input/Output error that showsI suddenly lost a partition that I was working on.On tightening the connection of the mini USB to the hard drive,I got the connection back, but the disk is remounted, so thatdisk label is not longer valid in my .bashrc and .bash_profile file.This is just a 6-month old disk, I think the only problem is the connection, I think the connection of the wire to the portable diskis loose at times, but there is no other major issue with this disk.So my question is: How to make the connection between the cable and

After updating to 10.04, I was able to connect easily to my network. However after getting a new router "Linksys WRT610Nv2", I was initially able to set up my wireless "WPA & WPA2 Personal"-encrypted network, but for whatever reason it stopped working completely.
My Asus EeePC 1000H does recognize my network, but its does not want to connect anymore, whatever I try. If I use no encryption, or go wired, everything works well. If I go on other networks everything is ok. I even reinstalled Passwords and Encryption Keys. Other computers (Windows-bad XP and Vista, laptop and desktop [sorry, but working on it to get rid of them!]) have no problems, either wired or wireless connecting with my network. Booting under 9.10, everything works ok as well. In Ubuntu 10.04, going into Network Connections and Edit my network, this is what I see:

Well I recentelly read some tutorials about "cracking" wep networks, and seems like it's kind of easy ( I Haven't tried'em out since I don't have my laptop right now, but i'll try them as soon as i get it back )So i'd like to change my network protocol to wpa2, but I REALLY GOT NO IDEA on how to do this.Does someone knows about a tutorial on how to do this?

First, I've dinked around with Linux b4 but never really considered it for an everyday desktop machine. After installing the ubuntu 10 release I have to say I am really impressed. This is going to be the kids homework machine!I had one challenge during the installation and that was getting wireless networking going. I set up Win XP first (to get the ndis driver and validate connectivity).After installing ubuntu I could not get the adapter (Netgear N300/USB) to connect to our router (D-Link DIR-825) using WPA2 and AES. Finally I got it to work after setting the router to only TKIP encryption. This works ok but causes the adapter to operate at a lower connection speed

My college runs a WPA2 LEAP secured wireless network, and I am having problems connecting to it under Ubuntu. I can connect to it just fine under Windows, just not under Ubuntu. Under Ubuntu I can connect to other networks such as my home WEP secured wireless network, so it shouldn't be a hardware or driver issue.
When I do connect to the WPA2 LEAP network it recognizes the network and tries to connect, it pops up the login box for me to enter my username and password, but after I click connect it pops back up again about 10 seconds later. It pops up like this about 3 times total, then after the third time it stops trying to connect and the Wireless Network Disconnected message is shown.

I've got a BCM 4312 card on a Dell laptop running 10.04 and an Apple Airport network. Since I configured the Airport to use "WPA2 Personal" Authentication, my connection is flaky: it drops for no apparent reason and sometimes I can't connect at all. When authentication is turned off, the connection is rock solid.
Here's an example from the syslog of a failed attempt to connect:
Code:
Oct 26 19:31:24 firefly NetworkManager: <info> Activation (eth1) starting connection 'Auto Rittenhouse'
Oct 26 19:31:24 firefly NetworkManager: <info> (eth1): device state change: 3 -> 4 (reason 0)

I currently have an Atheros a5k 802.11g PCI card and I am looking to upgrade to 802.11n. Are there any cards that support the Atheros chipset (a9k) or something similar? I do have PCIe x16 available if I can go with that. Plus, I could go with an external USB 802.11n wireless adapter, but I'd rather prefer the internal card to save space. I don't mind any PCI/PCIe adapters taking up slots in my motherboard, although I might plan to upgrade to an ATX motherboard so I can have more slots available.

I am using an eeePC with Xubuntu Lucid and I just configured a wireless network to run with WPA & WPA2 (wireless access point NetGear WG103). It tries to connect and then comes back with a request for reentering the passphrase. I have had this once before in a pub. The way I read this the driver is getting confused how to authenticate.

Unsecured and WEP networks are fine. I do not have a WPA network to test on, but my school's WPA2 Eduroam network does not work. It tries to connect before asking again for my credentials, and this repeats. I'm on 64-bit 10.10 Ubuntu upgraded from a live CD install of 10.04. Laptop model is Acer Aspire 5741-5193. Output of lspci:

I've recently installed Lucid Lynx 10.04 on my Dell Studio which uses an internal BCM4315 wi-fi card to connect to the internet. I was hoping it would work upon the install, but deep down I knew I'd have to tweak it a little bit to get it up and running the way I wanted. The card was instantly recognized but, at first, wasn't detecting wireless networks. This was quickly and painlessly fixed using System > Administration > Hardware Drivers, which I used to install Broadcom B43 wireless driver (b43-fwcutter). I rebooted and could not detect the local wireless networks.
I entered my password to my home network (correctly, I quadruple checked) but, unfortunately, it continuously tries to connect to the network with no successful. Occasionally I'm prompted to re-entered the password and the process repeats. The network I'm trying to connect to is a WPA/WPA2 network which I've heard to be troublesome. I haven't yet tried connecting to a WEP network but I'm fairly certain it will work and I will get back to this post when I test it in a few hours.
I'm curious if this question has been answered or if the problem has been solved and I just simply don't have the google skills to find it.

I just installed Ubuntu 10.04, everything is fine, but the wireless. When I try to connect to my WPA2 protected network, it is grayed out. SO I click Connect to Hidden Wireless Network, and this window pops up. I put in my network name, the security type, and password. It acts like it is connecting, the wireless icon is going up and down. But then another window pops up, saying Authentication required by wireless network and the down arrow is grayed out.

I wanted to run a little media server in my house, shared with my laptop only, so I could free up space on my laptop drive. I took one of my Linux boxes out of my render farm and loaded up a minimal install, command line only of Ubuntu Lucid from the mini ISO (32 bit). I had to plug in a lan cable to install, but I wanted to move my box back out to the "farm" that doesn't have wired access to my intranet.
After much research, trial and error, this is what worked for me. My wireless card uses an Atheros AR5001X+ chip, and it works with the desktop cd out of the box. I found the "just works" desktop install uses the ath5k driver that is now included in Lucid, but I'm not using a desktop or window manager. I haven't tried this on server version, if you do, let others know what you had to install to get it to work.
The things I do tell you about, I instruct you as if you are a newbie, however I have left out some things that users should know or be able to lookup easily, like if you want a static address instead of using dhcp. You may not need all of the steps or you may have to do more research and troubleshooting.
Find your wireless card (you may need to lookup what to do if it is not recognized at all)List all pci devices, only show network devices (-v verbose, -vv very verbose): >>lspci -vv | grep Network List all hardware (| less lets you pause at each page - arrow keys, page down/up to navigate, q to quit) >>lshw | less

In setting up wireless connections I have ran into an array of problems. First, when I installed the new OS on my laptop I had to get the correct drivers and firmware for it to display and connect to any connections, had no problem here connecting to a secure wireless network (WPA or WPA2). I then installed Ubuntu on my desktop and had to find the correct driver for the Netgear WNDA3100v2 USB adapter, got it all installed with the Windows Wireless Drivers tool or w/e it is. This made all the available connections come up. I tried connecting with the WPA password I was given for the network and will not connect.
I had the guy managing the network change the one I connect to, to a WEP Passphrase Shared Key thinking this would solve my issue, still nothing. And also in doing so, now my laptop will not connect to the wireless network using the Passphrase. I do not want to go back to Windows, and I will be getting rid of my Lan connection soon so i need a solution to fix this wireless connection problem.

I was using Fedora 14 for some months and my wireless was working fine. I've set up a hidden network with WPA2 Personal authentication. My laptop has an Atheros AR2413 802.11bg NIC and my modem/router is a Topcom Webracer. Yesterday I upgraded to Fedora 15 and I can't login to that network now. The only way to login again is to boot with the old Fedora 14 kernel that still shows up in my grub menu.I've searched this on these forums there are plenty of people with the same problem but the only suggestions are that the network card isn't supported by Fedora or the network card doesn't support 802.11bg.some suggest changing the authentication method in the router... and the only one who got it solved was by rebooting the router... None of this addresses the fact that the same hardware/network was working just fine in Fedora 14. And I still can't find a way to have a wireless WPA2 connection with Fedora 15.What can I do to fix it?
