Ubuntu Networking :: Won't Connect To Open (unsecured) WiFi Networks?
Jul 9, 2010
I have no problem with my wireless network at home, or visiting friends, but it won't connect to public, open, unsecured WiFi networks, eg hotels, trains, ships.I'm using Ubuntu v9.10, NetworkManager applet v0.7.996, on a Dell Inspiron 1750 laptop.If I left click on the NetworkManager, the available wireless networks are displayed and I can see the relevent open networks, named as expected and shown without the lock icon. I click on the relevent entry, watch a spinner for 30 seconds or so and then it drops off and I have no connection. This happens for "all" open connections.If I look at my defined Wireless Network Connections now, I can see, eg, "Auto Internet@Sea, Last used: never". Editing that connection:
I have been an Ubuntu user for a year or so. My level is still ultra n00b but I am trying. Whenever I update Ubuntu there is always a WiFi problem, always. So now I am having problems getting wifi to work in 10.10. In Network Manager I can view wifi networks fine but I cannot connect. I tried with wicd also but I got as far as "getting ip" and then it would hang up.
I am not sure what driver I am using as I don't know how to exactly ID my driver. I know there is a way to ID the driver using airodump-ng but I have yet to find it. I have a feeling this is a driver issue as one time I was able to establish a connection that then dropped a few minutes later. I have a feeling I should be disabling/removing the current driver and replacing it with ipw3945 or possibly a driver ndiswrapped? The problem is I cannot figure out how to remove the current driver.
I was going to switch back to 9.04 but I thought I would try to manually figure this one out instead of taking the easy way.
I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.
I can connect to any wireless network it seems other than the unsecured wireless network here at my college. As long as you register your mac address, which I did, connection should be fine. I have no issues connecting via ethernet, but I need the wireless also.The wireless controller is Intel Wireless WiFi Link 5300. I tried alternatives to the Network Manager and I've looked all over google which I haven't seen many issues, it should work fine.. not sure where to go from here.
I am attempting to connect to an unsecured wireless network; I helped set it up for my local club with a local ISP. Once things were up and running I took my wife's laptop running Ubuntu 8.04.3 and Wicd. Can see the unsecured network no problem, good signal, hit connect, whirs away for awhile, then: 'Unable to obtain IP address.' Strange. I am about to give up and report back to the ISP when I think I might try one of the old Windows boxes in the computer room. Spots the network, hit connect, online, no problem.
So Windows connects fine, Ubuntu box can't get an IP though no doubt the router is trying to serve it one.
im wondering if there is something like [URL] that would allow me to automatticly connect to first open wifi with internet for linux.if no, would it be hard to write a program that would do that for me?
I can normally connect to most wifi connections, but for some reason I can't connect to my broth's-gf-parent's network. Windows 7 can connect to it just fine, but not Ubuntu. Once in a while I'll go to a cafe, and this will happen there too.hough, like I said I can normally connect to all other wifi networks with no hassle
got a dell inspirion 15r (i think), and it comes w/ win7 (I HATE Win7) so i made him let me dual-boot with ubuntu maverick meerkat. (he wouldn't let me get rid of win7 cuz thats what his parents use.) It installed successfully, so we booted into it, and there was no wifi networks. I thought it was because wifi was disabled so i press the button i think its F5 but still nothing. I thought it might have been the comp but i booted into win7 (Que the Beethoven's fifth)... and it worked in win7 (thats a first) can someone help me. Oh and i forgot i used that terminal command to unblock wifi
DELL Inspiron 1501 Broadcom BCM4311 is the wifi adapter.The problem I am having is that I cannot get to search for wifi networks. It looks like the driver and everything is there but the wifi is disabled for some reason.I installed the drivers provided by the "Additional Drivers" application and they do not work.I also followed this fix and I could see in the menu that the wifi was added but I was not able to click it or look for wifi's URL...
I was on a car trip earlier, but we were stuck in traffic. The stop-go stop-go kind of BS. I pulled out my 9.10 laptop and figured I'd scan for wifi networks and see how good America was at securing their networks. (I work in IT support so it's one of those things I preach to no end yet people rarely listen).
I was using wifi radar, and picked up a truckload of networks every time we'd stop. But something didn't sit well with me. When I click on the network manager icon in the top gnome panel to see what networks were available, it never seemed to refresh.
Example - the first 5 networks I saw were 1, 2, 3, 4, 5. We would stop-go more and more and miles later when I'd see more networks in the area show up in wifi radar, yet hit my network manager, I'd STILL see networks 1, 2, 3, 4, 5 and not 30, 31, 32, 33, etc like I expected.
What kind of refresh time or cache or whatever does network manager have? I just didn't understand why I was seeing the original networks from 15 minutes/miles ago and it never seemed to update.
I'm using Ubuntu 10.04 - 64bit install with an A215. The wifi was working fine until today. Ubuntu seems to detect the hardware, and it shows the interface as being 'up', however no networks show up in either the network manager or 'sudo iwlist scan'. I'm not sure if it's a driver issue, or if the hardware itself died.Here is the output of lspci:

Fedora 10 (dual boot w/ XP) on Dell Optiplex with a Dell wirelessntennaI am on a university campus with campus-wide wifi network (so no router). I have a wireless HP printer that I want to be able to print to using an ad-hoc connection. The wireless antenna, networking, and wireless printing are all working in Windows XP (so hardware is OK). However, on the linux side, the wifi is really really finicky.
When I first boot up to fedora, it usually connects no problem to the campus-wide wifi network. If I try to switch to the ad-hoc printer network (which it sees), will not connect and, furthermore, it will no longer connect to the campus-wide network (and sometimes it doesn't "see" this network at all). It seems that restarting the Network Manager service sometimes helps to reconnect to the campus-wide network, but not always and I can't connect to the ad-hoc regardlessNOTE: I'm just barely a linux user, and I didn't set up my system - don't assume that I did anything that would be common sense and, if you can, walk me through your suggestions.
I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

I have an hp dm1z and ubuntu 10.10 64bit. After I suspend (close the lid) and wake it up (open the lid) at a different location with a network connection (wired or wireless), my system always fails to connect. I need to reboot and then it sees the network and connects fine. I have tried /etc/inet.d/networking restart, but nothing changes. The only exception to this rule are two networks that have WPA security settings and are stored. I can always switch between those two. I have tried ifconfig eth0 up & down and restart networking. I have also tried to connect manually (dhclient) and no success. None of these work. I am including the output of lshw -C network.
I have an MSI Wind U100 netbook running Maverick, and it has a Realtek RTL8187SE Wireless controller according to lshw. My computer can "see" some wireless networks where they are present, meaning when I click on the little network icon at the top of my screen it shows the available networks. But when I click on them to connect, the icon does its little "connecting" motion, but I never receive any message saying "Connected" and when I open Firefox and try to browse to google.com, it says "Server not found"
I have an ethernet card connected to my LAN and a USB cell modem internet connection. I am running ubuntu 10.10. The problem is this: I can use either network, but only am connected to one of them. If I connect to both at the same time my speed drops to zero.f I disconnect one, the other starts working. I have done a lot of searching and reading, but it looks like I don't know how to find what I am looking for.My LAN was setup as 3 WinXP computers peer to peer. One of those computers was replaced by this one that I am having trouble with (computer A). Another one was replaced by one that is not yet on the network (computer C).Computer B dual boots Win XP and ubuntu 10.4. Mostly it ns xp for Quickbooks and BobCAD, also it is connected to the printer. My router is setup for DHCP
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 have installed Ubuntu for netbooks on my four year old laptop and of course the wifi card is unable to search for wireless networks when I'm booted into Ubuntu. I do have the driver software on a recovery disk. Would installing it in Ubuntu fix my problems?
Tonight I replaced Ubuntu 10.04 with Kubuntu 10.10. While running Ubuntu 10.04 wireless worked fine and I had no problems. However, now with Kubuntu 10.10 I seem to be having a bit of a problem with the wireless. It will only connect to a wireless network that is 'open' (no security). It sees the network i want to connect to, but when i go to put in the correct security values it does nothing. Never seems to try to connect again. I've edited both the local Kubuntu wireless settings, as well as change settings on my router (went from WPA to WEP just to see if I could get it to work. It didnt).
So im wondering if there is any other software I could use to try to manage the local wireless hardware to see if different software will connect? Here is my iwlist, not that it helps but at least it proves my hardware sees the wireless i want to connect to.
I have Lucent Technologies Orinoco Silver 11 Mbps PCMCIA wifi card. It worked perfectly in Fedora 10, but after updating to Fedora 11 it stopped finding any wireless networks. The updating were done with automatic updating utility. The card works perfectly in Windows, I tested it today.
My laptop is HP nx6110 if that matters.
Here is the situation:
When I plug-out the card, the Network Manager disables wireless networking as it should. When I plug-in the card, wireless networking is enabled, so the system seems to recognize the card in some way.
If I try to connect to "Hidden wireless network" (because there isn't any wireless networks listed in the Network Manager) system tries to connect for a couple of minutes, and then asks wireless settings again. Orinoco card's lights DOESN'T blink normally when connecting to the network (one light should blink rapidly and one should light continuously, but both are blinking rarely or doesn't blink at all).
In System->Administration->Network in tab Hardware (hope those names are correct, I use Finnish version of Fedora...) is:
It seems that the card is detected right.
Here is what I have done to get the problem solved: In System->Administration->Network I have tried to connect to the wireless network manually (disabling the Network Manager). I can't get the connection. It gives me random error messages, sometimes "Check the cable" or something like that, sometimes just timeouts IP determination.
I have tried to connect different wireless networks, no connection. All tested networks worked with another computer.
No matter if I reboot or service network restart or plug-out plug-in the card... the problem still appears.
Tried to find (and reinstall) drivers:
No Matches found
Here is the output of lspci. The output is the same if the wifi card is connected or not.
We have two networks,one is 10.0.0.* with mask 255.255.255.0 & the other 20.0.0.* with mask 255.255.255.0 and one linux(RHEL5) PC with two network interface eth0,eth1.(configured as Router) eth0 is 10.0.0.1 and eth1 is 188.8.131.52 we have enabled IP_Forward using "sysctl w net.ipv4.ip_forward=1" cat /proc/sys/net/ipv4/ip_forward is 1 but unable to ping from one network to other network.
two networks are connected to Linux PC.(10.0.0.1 & 184.108.40.206)
still wht configuration required to establish the connection between two networks using LINUX PC.
from router(linux PC) both network PC's are pinging but not from one network to other network.
I recently ubgraded to ubuntu 9.10 from 9.04, but I had the same problem there. I can see the secure connections, but when I try to connect to them, it tries to connect, works at it for about a minute, and then asks for the password again. This just started a week ago or so. I am new with ubuntu, so while I know that there are terminal outputs I should probably post, I don't know which ones.
I have a machine running Xubuntu [2.6.22-14-generic]. I have been trying to get this machine connected to wireless for ages, and I'm having another stab at it. So far I have install ndiswrapper and loaded the driver for a Linksys wireless adapter. The output of 'ndiswrapper -l' reports:
So as far as my newbie knowledge goes, I believe that step to be completed, correct?When I turn on the machine is type in
sudo sh modprobe ndiswrapper
to get the card running to where it will appear in the iwconfig dialog.The commands 'iwlist wlan0 scan' will list all the wireless networks around me, but I have been un-able to connect to any network, even unencrypted ones. I have tried to connect both through Wicd and command-line to no avail. For command-line I have used:
sudo ifconfig wlan0 down sudo dhclient -r wlan0 sudo ifconfig wlan0 up
With the final 'dhclient wlan0' commands, the following is returned:
There is already a pid file /var/run/dhclient.pid with pid 134519120 Internet Systems Consortium DHCP Client V3.0.5 Copyright 2004-2006 Internet Systems Consortium
I have attempted to go ahead a step further and connect to an encrypted wireless network, however, I receive the same message, as well as another error message upon trying to enter the key, with the following code:
iwconfig wlan0 key s:"thekey"
Error for wireless request "Set Encode" (8B2A) : SET failed on device wlan0 ; Invalid argument.
I have an Atheros AR242x card. It can see my wireless network (WPA2). When i attempt to connect to the network it asks for the WPA2 passphrase. After entering the password it begins connecting but hangs up for about 3 minutes before saying wireless disconnected. The wireless worked for one day on a fresh install (Ubuntu 10.04)and then started doing this.
I have a WLAN Driver Azure Wave AW-NU222 Wireless LAN Card in my Medion computer.
After installing Ubuntu it seems to detect the wireless networks in my area. However, when I try to connect to my network, it tries for several minutes and then times out with no error message. I have set up the credentials and also tried removing the encryption (WPA-PSK) from the network itself, but it still doesn't connect.
Connect via an Ethernet cable is fine, and I know that the network is good because I can connect via my Windows Laptop and various other wireless devices.
I suspect it's due to drivers, but I'm having trouble downloading a driver which I can try and install using Ndiswrapper. The Medion website just a windows executable when I try and download the driver specific to my machine when I really need the .inf file.
