Ubuntu Networking :: APs Are Visible But Not Able To Connect.
May 15, 2011
I have tried to get familiar with ubuntu and kubuntu few times. With kubuntu I had multi-display problem which I couldn't solve myself. Then I changed to ubuntu 10.04 and 10.10. I did not have multi-display problem but wireless network problem which I could not solve myself either.I try once more with ubuntu 11.04 but now I try to use your help to progress to avoid many days and evenings wasted time.So again I have problem to connect to wireless network.
- I can see wireless access points
- When I try to connect one of them after entering router password after a moment I get error to not able to connect and I am asked the password again. (WPA & WPA2)
- Wired network works ok.
- Router is Buffalo WBMR-G125
- Wireless USB adapter is Buffalo WLI-UC-G300n
- Computer is self made PC with Asus M4 motherboard

I have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?

After upgrading from 10.10 to 11.04 and running an update ubuntu can't connect to any wifi networks, although it can see them perfectly (and potentially unrelated, the windows partition is having major dns issues with the wifi too).
I've looked around and can't find an obvious fix, just a bunch of posts from people with the same problem that wasn't solved. I got frustrated and was about to install 10.10 again but I noticed I couldn't connect to the wifi on the liveCD either. I then tried the 10.04 liveCD, and the internet worked aswell as when I installed it. However before when I upgraded from 10.04 to 10.10 I had no problems with the wifi, so it leads me to suspect that there was something installed/some setting in 10.04 that is missing from the latter version.

I have just installed Fedora 13, everything seems to work but the Internet connection. 3 devices are shown in the "Network Configuration" window (devices tab)(under "Network Device Control")"Network Cards" (wired) (wireless) and even the Motorola Modem from the ISP as well as all of the primary and secondary "DNS's", but will not connect! I have Broadcom devices on a Dell Latitude D600 Laptop. On the upper right of the desktop, the connection icon shows when I plug and unplug the cat5e, so it sees something there, but will not connect.

i have 3 comps(running ubuntu 10.04) and a laptop(running vista sp2). i have installed samba on all ubuntu comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet.the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.all the systems have a static ip.

I'm travelling currently so the last network i connected successfully to was my home wpa-psk network. I hadn't tried anything until i got to my accommodation that is an open network (that I'm on now on the Win7 partition on my laptop).
The network (and a similar archetypical 'linksys' open network, aswell as some protected local networks are correctly displayed in network-manager and upon selection, it happily spins around to its hearts content for a while before saying 'no chance boy'.
/var/log/syslog spills out the usual combination of wpa_supplicant and kernel messages, the most interesting of are that the kernel deauthentication reason 6 response. 6 apparently means class2FrameFromNonAuthStation...Client attempted to transfer data before it was authenticated.
Anyone seen anything like this? I've already tried going closer to the router to no avail. I don't remember seeing this any other time I've connected to a open AP, even if that AP is far away. (Signal strength for this AP is good, kismet says its around -57dBm, well above the threshold of -80dBm, and I've tried all the suggestions from the 'Related Questions' code...

I've been searching around the internet for the last two days trying to solve this problem, because I know how much everyone hates people who ask questions without looking first. Alas, I haven't found anything.
I have Ubuntu Server 11.04 running on a spare machine, which I've configured and got running just fine. I am trying to set up an IRC server on this machine for some friends of mine using UnrealIRCd. I have built and configured the server program, and am able to run it. Anyone who is connected to my home router (wirelessly or hard-wired) can connect to the server while it is up using either the internal IP, external (router) IP, or the dyndns.org name which is tied to the external IP.
However, anyone outside my home network cannot connect to the server. I DO have ports 6660-6669 forwarded on my router (IRC standard port is 6667). When connected to an external network, I cannot join the server by using the external IP, nor the DNS name.
I also have OpenSSH set up on the server machine, and have port 22 forwarded on my router. I CAN ssh into my server machine from within my home network, and I CAN ssh into my server machine from an external network.
Strangely, I can successfully ping my DNS name from inside my network, but not from outside. This doesn't make sense to me considering I am able to successfully ssh into the machine.

I'm trying to share some folders over the network, but the shared folders are not visible on another computer. This is through double clicking my computer from the Network list in Nautilus. However, I can access the share by typing the full address(<computer name>/<share name>) in "File > Connect to Server...".Since I can't type the address manually from my blu-ray drive, I need to get the shares to show on the network. What is wrong with my settings?

I have two computers in the house that I have shared folders and one has a shared printer. I have a desktop running 9.04 and a laptop running 9.10. The desktop has several shared folders and a shared HP printer. The laptop only has one shared folder. Everything was working fine up until a couple days ago. I went on the laptop to access one of the desktop shared folders, and nothing shows up under "places, network" except windows network.
It no longer shows that the printer is currently shared either, but the funny thing is that I can still print to the desktop from the laptop.I just can't figure out how to access the shared folders.

I've set up Samba under Ubuntu for windows SMB file sharing (currently unauthenticated but soon to be backed off against A.D.) This is great within Windows where l folders are available as mounted in all applications but from my Ubuntu desktop and Ubuntu laptops, we can only access network folders and files from the File browsers and bookmarks one finds in the "Places" menu. Our issue is that most (but not all) dialogue boxes don't have any options for viewing non-local files and folders. i.e. when I'm in my web browser and I go to upload a file from our local network file server to an internet location, the "Open" dialogue box cannot see any of our local network locations.

i'm trying to set up samba so that i can connect to the printer in the den since we have wireless access. also, i can see my virtual box on the windows xp home ed desktop, but can't access it.so, how do i go about setting up samba so stuff is visible between my ubuntu machine and my families windows orientated network? i'm having a hard time finding anything on videos too. i'm taking a break from the remastersys stuff so i can get the more important things done, such as connecting my ubuntu machine to my families windows network. i don't know if the printer is wireless or not, but regardless, i can't find it.

I am trying to access a shared printer from one Ubuntu PC to another.
On the Server PC, I have the printer working, I have set it to shared, and I have set the server setting to Publish shared printers. I can see and use the printer fine from a windows PC.
On my Ubuntu Client PC, I have samba installed, including smbclient, and all other samba components I can think of. I can see other computers on my home workgroup (Windows and Ubuntu fine). I can also add a printer connected to my windows PC. However I cannot find the printer connected to the other ubuntu PC.
I see the instruction in the Samba guide saying
"Now enter your Ubuntu Samba Print Server (set up as above) IP address in the box on the left titled "smb://"."
However I do not have fixed ip addresses, so what am I supposed to enter in the box. If I enter nothing I can browse the network and can see the host computer, but the printer is not displayed. I can also see the printer connected to the windows PC. How do I 'see' the Ubuntu printer?

I have the problem with Ubuntu to access the local site within my company network. This network has access to Internet, but the company's site does not have a public address. It is like "http:e-learning.local". I can access this site from any windows machine, but I can't access it from ubuntu. Only if I use IP address, I can access it. However, I have normal access to other sites on the Internet.
Do you have any suggestion how to solve this problem?

I'm having a problem with my wireless, and after searching the forums for a couple of hours, I suspect it's time to speak up.This morning, wireless was up and working fine on several networks. My laptop froze around noon, and I was forced to do a hard reboot. After restarting, the Network Manager will not connect to any wireless networks, which are visible. Wired connections work fine. I've tried multiple networks, and although I can see them, I cannot connect.

If so, This will be a very dangerous security problem.

I am using Network Manager to connect to a VPN server so that I can access some of the computers on the local network there. When I'm connected, I have two problems: All my internet traffic goes through the VPN. My computer is no longer visible on my local network. I waste a lot of time connecting and disconnecting the VPN. Is there any way I can set up a VPN so that I am still on my local network and only requests to 172.x.x.x go through the VPN. I suspect it can be done with iptables, but all the info about iptables goes WAY over my head.

I have setup samba (samba + openldap) as my pdc. Some windows systems which are added to the domain are not visible through the windows xp's network neighborhood. However all the clients can login, browse other systems except for those which are not listed in the network neighborhood. I have attached the smb.conf file for reference.
Code:
[global]
workgroup = MOBIAPPS

I have two computers running Ubuntu 9.10, both have one shared folder. These were set up via Nautilus.
On computer 1 I can see and use the shared folder of computer 2 just fine.
On computer 2 I can NOT see the shared folder of computer 1 anymore since recently. I has worked in the past.
Some more information: the name of computer 1 is "daniel", the share name is "gedeeld". So the address of the shared folder of computer 1 would be smb://daniel/gedeeld/
Opening this address in Nautilus works fine on computer 1 (that shares the folder), but results in an error on computer 2.
Error: failed to mount Windows share. Please select another viewer and try again.

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
