Ubuntu Networking :: Unable To Use TL-WN821N?
Mar 3, 2011
I got a TP-LINK USB wireless module - TL-WN821N, using Ubuntu 10.4 (same problems were also seen in 10.10).
From everything I've read online, the usb should work just fine, since the Atheros ar9170 is built into the kernel. However, when I plug it in, it is detected as a USB device, but there is no wlan associated with it, and basically - nothing happens. Am I doing something wrong? what should I do so that the Atheros driver is associated with this device?
btw, on Windows it works fine (with the drivers).
Some logs:
Code:
$ uname -mr
2.6.32-28-generic i686
$ lsb_release -d
Description:Ubuntu 10.04.2 LTS

get this working all of the time instead of the constant dropping that I experience -- i've read a lot of the posts and think i have the right driver installed but there never seems to be a major improvement.Running a p4 2.8 ghz system on lucid and have the most recent kernel installed.Thought I'd give it a last attempt with help before chucking it and getting an adapter that's more compatible

I need some help, my wirless usb card which is a TP-Link TL-WN821N card was working fine, except that it would drop the connection once in a while.I got the windows XP driver and used the graphical ndiswrapper tool to install it, and "Hardware Present = Yes" showed up next to the driver.So I followed the guide and edited my blacklist.conf to add the the atheros and any other conflicting drivers.After that, I rebooted, but iwconfig and ifconfig doesn't show my wireless card anymore.
lsusb shows that the card is detected,I can also tell cause the activity light is constantly on instead of it blinking.I decided to uninstall the windows wireless driver from the graphical tool, and hash out the blacklist entries and reboot the pc. But still my wireless card is not working.I just want to revert to ubuntu's own driver, how do I do that now?

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Tired of ongoing Win 7 issues so I decided to try Ubuntu 11.04 as live-CD. The PC is a 2 year old machine with reasonably fast CPU, plenty of RAM etc. In Win 7 I had successful connection through my Dlink DWA-125 USB adapter. In Ubuntu 11.04 I can see the access point (also a Dlink unit) so it appears that the DWA-125 is working but I am unable to connect. I am using WPA security and I have double checked the password for the router.
Ubuntu appears to try and connect but after about 15 seconds I get a dialog box that says: "unable to connect". I have two MacBooks running off the the same access point at the same time so clearly the access point works.

I've been using SSH for a while, but only to connect to machines on my network. The problems start when I try to connect from somewhere else!I have set up port forwarding on my router.
I have ssh connections on port 22 set to forward to 192.168.1.138 That machine is a Mac, and the user is stephanie. On my network, I connect with stephanie@192.168.1.138(duh, that's the easy part).
NOW, I'm trying to connect from a different network like so: stephanie@XXX.XXX.XXX.XXX<- This of course being my IP. What should (I think?) happen, is the connection is recognized as SSH, therefore forwarded to the machine I specified.
One of two things happens here:
1. I get a timed-out error or
2. It asks me for a password. I have keys on the two machines, so I usually have a password-free connection. If it asks for the password, I enter what the password would be, and it tells me access denied.

I have tried installing the original CD os 8.04 (Dell system restore) again hoping that everything was on there in order to get me connected to wifi again. Connecting to wifi seems to be the main issue that people have trouble with.I feel that I have 3 options now:
1. Sell the laptop (it is a month old!)
2. Pay for support
3. Put windows on it
It is a shame as I liked Ubuntu 9.10

It is a wired connection through Time Warner and worked flawless with XP. It will not load any page except for google.com homepage and I cannot access any of the links in the search results of google. I know the internet works since google will load and I have done all that I can think of (ping and manually enter my connection) and nothing works. I am running the OS on a Acer Aspire M1610 desktop.

I have Karmic Koala and together with my neighbours we have a W-LAN which I was always using without problems. Now, a couple of weeks ago, my neighbour has changed the password to this W-LAN and since then ubuntu is unable to connect. The network is being recognized, but after the request to unlock a key for the network manager (besides, how can I unlock it once for all?) there comes the window with the request for the network-password, after typing it (correctly), nothing happens. The request for the password comes two more times and then ubuntu states that it is unable to connect.
- We have changed the password again - didn't help
- On Windows I and my neighbours get the connection
- My Ubuntu is able to connect to all other W-LANs

I have an Ubuntu server dedicated to running an openVPN server on my VMware ESX 4 host. On my Windows clients I am able to connect to the VPN; however, on my Ubuntu 10.10 workstation I am unable to connect. Here is what I have done. I have network-manager-openvpn and dependices installed as well as the openvpn package. When I hit the add button in the network manager for VPNs, I fill out all the needed information, but am unable to hi the apply button. I have also tried using the openVPN method for connecting. I download the client.ovpn file from the VPN server, and issue the following command:
Code:
openvpn --config client.ovpn
It asks me for the authentication user and its password and produces this:
Code:

I can't ssh to a pc on the same lan segment until after I do an arping to the server.
This is the ssh version running on the Ubuntu server OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010
This is the ssh version on the Arch client OpenSSH_5.8p2, OpenSSL 1.0.0d 8 Feb 2011
I've tried these options in the server /etc/ssh/sshd_config, but they haven't helped
GSSAPIAuthentication no
UseDNS no
Reverse dns look up from the server using dig -x ip address of client ip always seems to come back immediately.
I don't know why I tried arping to the server but it seems to do the trick everytime. Then I can log out of the server and ssh back in immediately

I am unable to share a folder on my Ubuntu 9.10 desktop machine. Networking is working, I can see and be seen by windows machines and also my Ubuntu 9.10 laptop. The laptop is able to share folders with no problem. The error message I get when I try to set sharing on a folder is "'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Memory allocation error."
I know there has been a thread relating to this in the past, but the solution there did not work for me, and I have been beating my head against the wall for a couple of weeks on this problem, and have spent a bit of time with smb.conf. I would hate to have to do a new install to fix this, after all this is not MS windows!Can anyone point me in the right direction?

I've used Ubuntu for almost 3 years now and now I'm forced back in the arms of windows. Unfortunantly the only internet connection thats available here is a 3G modem connection. When I bought the connection a Huawei E122 modem was delivered to me.
When I plug it in it recognizes the modem as it should and it even lets me set it up. But then when I connect, it fails.I have googled around for a couple of days and I've come up empty handed.I really want ubuntu back, and still be able to use the internet.I have a Asus EEE 1008ha laptop and use ubuntu 9.10

My onboard lan card was cutting out during samba file transfers so I put in a PCI lan card and disabled the integrated one. Now I'm having trouble getting it to work. I appologize in advance, I'm completely ignorant as to how to change net cards in Ubuntu and am quite new to Linux in general.I'd copy and paste my lspci, but I can't connect to that computer nor the internet with it now.

I am trying to keep a VPN connection open between two Ubuntu 8.04 LTS servers, one in Holland and one in China. Unfortunately, because the connection in China is not great, about 1 time a day the connection drops. I have therefore devised a script, to be started by crontab once every 5 minutes, that checks the connection and if necessary restores it.
Code:
#!/bin/bash
ping -c 2 -W 10 10.10.10.73 &> /dev/null;
PING = $?;

I always use Shorewall on my Ubuntu Servers and it works great, one things I have never been able to get right is the TOS.Let say for example I would like:
HTTP traffic (80, but all traffic get routed to 3128 [Squid]) to get highest priority
SMTP (25) second highest
POP (110) third highest
The rest forth
How would I get that right?
