Ubuntu Networking :: (11.04) Wireless Networks Detected But Not Connecting?
Jun 5, 2011
I have ubuntu 11.04 installed. I have a D-link USB Wireless Adapter. Ubuntu detected it and it worked fine. I have a Beetel 450TC1 Router which broadcasts my internet connection. Ubuntu recognizes it, and keeps on trying to connect.It asks me for Authentication again and again.( Don't tell me to check the password again, it does work on everything else )And its not the router problem also, as I tried broadcasting through a laptop I have, Ubuntu again detected but couldn't connect and kept asking me for Authentication
I have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.
I'm dual-booting Ubuntu 9.10 (upgraded from 9.04) and Windows 7 on my Dell Inspiron 1525 laptop.Ubuntu doesn't recognize any wireless network (both in 9.04 and 9.10); my Windows OS works perfectly well with wireless, as does my wired Internet connection with Ubuntu and Windows.I've had this problem on previous installations of Ubuntu (I've removed and re-installed it several times) but I can't locate the solution anywhere. I've tried numerous fixes that I've found online, but none of them have worked.System>Administration>Hardware Drivers tells me that the Broadcom STA Wireless driver is activated and currently in use
I've tried every fix i could find. I'm on a Dell Inspiron 1420 running Ubuntu 10.10 lucid lynx using a BCM4312 LP-PHYi've tried everything to get my wireless networks to connect but nothing works. I finally got my computer to recognize my wireless card but it doesn't detect or connect to networks. Before i was able to at least see the networks but not connect or stay connected once i disconnected the ethernet cable. i will post the output of ifconfig, iwconfig, iwlist scan
I've used this computer to connect to a wireless router before. I recently moved and for some reason it isn't working.I have a too long of an lspci output to type (I'm on a different computer).
I have a msi netbook with ubuntu netbook remix installed and it was working great until yesterday when suddenly it stopped detecting my home network. There are no problems on my two other machines, so I'm sure the problem is the netbook. I have no idea how to go about troubleshooting this. I was hoping someone could help me by giving me a place to start.
New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.
I'm running ubuntu 9.10 on my desktop.Wireless networks appear on the dropdown menu but when I try to connect to my home network the authentication box appears, after typing my password the box disappears and it continues to connect but nothing happens and after a while the authentication box appears again. So.. no internetz connected.
I have a created a wireless connection from the main admin account and checked the box saying "Available to all users", everything is working correctly. I only need to prevent the Desktop Users from switching the connection to another one.
I am running debian testing dist-upgraded to sid with the latest gnome-shell. All is fine, I have recently moved to a new house and noticed that network manager wont detect my home wireless network. It does scan for networks and locates SSIDS from other local networks including my neighbours wifi where I can connect but will not detect mine. The modem router used is a zte quite popular in Greece and I have the broadcom wl driver installed. By the way since it is a dual boot machine - nasty win7 connect just fine and so does my mobile phone...
My wireless network is being detected but it refuses to connect to it. I am entering the accurate passcode and I have tried doing various commands for it to work, but it is being stubborn.
Also, it would help to know which WEP Index to use and type of Authentication.
I am running -current on an ASUS eeePC 1000HE. Wireless was working fine up until the time I applied the latest changes from the Slack -current tree, which upgraded wpa_supplicant. Now, no networks are detected.
I looked at some related threads here and did some basic checking: neither the eth1 nor wlan0 interfaces show up in iwconfig or ifconfig output. Am afraid I am still a wireless dunderhead and don't know where to start troubleshooting this issue.
I have configured a wireless pcmcia card using ndiswrapper. I'm sure that works, as with the command "iwlist wlan0 scan" gives me back the list of detected wireless networks. At this point I was wondering: is there a way to detect the new interface (wlan0) with network manager? Even after enabling the wifi card the network manager gnome applet always finds only eth0.
I installed ubuntu and i installed it using the install as a program inside windows options but when I boot into ubuntu it does not detect any networks I tried the command sudo pppoeconf it says ethernet card is not there and then it asked me to try modconf and when i try modconf it says that modconf is not installed How can i set internet connection in ubuntu 10.04 I get address assigned by DHCP
I have 2 network cards in my computer, and I would like to connect them to 2 different networks. Both connections work fine when I use them so that the other one is unplugged, but as soon as I connect the second plug (doesn't matter which one is first) they both stop working.I've been googling and reading dozens of pages about how to set this up, but I still can't figure it out.
One connection gets its addresses from DHCP and that connection is used for pretty much everything. The other connection has a static IP, and is used to access just one other computer, which is in the same subnet as that static IP.I'm using Ubuntu and I've been using the NetworkManager Applet to manage my connections. If I've understood my googling correctly, NetworkManager Applet can't be used alone for this kind of setup, is that correct? (Even though it has that "Routes..." button and "Use this connection only for resources on its network" which I've tried for the connection with the static IP, but they don't seem to help.)
So my questions are:
1. So I really can't use NetworkManager Applet for this?
2. What software / tools should I use instead? (My googling brought up such wildly different solutions, and I don't know which ones are outdated, if any.)
3. Should I get rid of NetworkManager Applet completely?
I'm familiar with routing in theory, totally clueless about the networking tools in Linux, but happy to read manuals and happy to learn to use the command line versions if anyone can point me to the right direction.
I would like to my laptop to connect to two networks at the same time.The first network is wireless through which I access the Internet.The other network is a wired router to which my laptop and another computer are connected. would like to connect to the two networks at the same time so I can access the Internet, and talk to the other computer on the wired lan.My problem right now that I can only connect to one network at a time. Even the act of plugging in the cable for the wired network causes the wireless to cease functioning.Could somebody give specific steps. I am on Ubuntu 11.04.
I'm having another slight issue. On a clean install of Ubuntu Studio (10.10), I have installed network manager (manually, using .deb packages, one at a time, including all the extra ones it required) and I can only connect to non-secured networks. If I try to connect to our home network (which has WEP security), it sits thinking about it for a while (with the wireless light flashing, indicating it is doing something), but after a while, it asks for the WEP password again. it works fine if I turn the security off
I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet eth1 :192.168.1.222 is connected to the local network eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.
using a text interface for my computing but I have run into an issue. Does anyone know of a CLI networking tool that will allow me to connect to a non-broadcasting network? I have tried cnetworkmanager and attempted wpa_cli. The first does not seem to support it and I have not played too terribly much with the second. I have discovered that when I boot my comps into KDE and tell NetworkManager to connect to the network cnetworkmanager can find it then, but that does me no good for what I want, which is to boot my computers straight to runlevel 3 and get connected. If it means anything I am running F11 on a Dell Inspiron 1521 Laptop with a Broadcom wireless card (awfully annoying to set up, but it is working fine) as well as F11 on a desktop of my own designing with a Netgear wireless adapter.
P.S. I realize that broadcasting the network would be the trivial solution but alas I am not the admin on the router and he is out of town.
Here is the setup I have. Two debain (squeeze machines) A1(eth0,192.168.33.1, netmask 255.255.255.0) and B1(eth0,192.168.43.1, netmask 255.255.255.0). They both have 3 nics'. So I am trying to connect to each other with a crossover cable and I have added the routes manually. eg: on machine A1 route added was
I just installed ubuntu 9.10 in my freinds laptop and it has a realtek 81878 wireless card...it detects the wireless networks but when i connect it just keeps on asking for the authentication key again and again.
I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output: emil@emils:~$ iwconfig lo no wireless extensions.
I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:
For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.
I am using a Toshiba Laptop model P205D-S7802 with an atheros wireless card. Since I upgraded to 10.04 I am unable to connect to the internet unless I use an ethernet cable. I have been surfing the threads for a fix and have tried what has been posted but to no avail.

I'm running Ubuntu 10.04 64bit on a Thinkpad T61, and I keep running into some issues with the wireless networks. For a while, the connection works fine (sometimes several hours, sometimes 15 minutes or so--there doesn't appear to be an event associated with it). Eventually, though, the connection disappears; first, though the widgets say I'm connected, nothing will go through, and soon after, it realizes I'm not connected and, moreover, it can't find a single wireless network, despite the fact that it was just fine a couple of minutes beforehand (and other devices still have access to the WLAN, so I know that the router hasn't crapped out). I've tried using wicd, but the same thing happens.
