Ubuntu Networking :: Can't Connect To Network Open / Wep Or Wpa
Apr 30, 2010
I made the switch to 10.04 today, fresh install from the alt cd.I'm using ndiswrapper, I Guess I'm using version 1.55, with utils vesrion 1.9.In 9.10 I've used the driver from this thread, specifically this post, it worked with wep and wpa-psk.I just installed ndiswrapper and am using the above driver, I can see networks but can't connect to my network open, wep or wpa.Any one have any ideas or know of another driver that works?

When I first installed my OS, Elive17, I had no problems connecting to my wireless connection at home. I scanned for networks, found our home network, typed in the key, and bingo! It still works. However, I can't connect to a open network at university. It's not encrypted, so I should be able to connect. What should I do?

I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.

I recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.

I've installed 10.10 yesterday on my old HP Pavillion ze2000 as dual boot with windowsXP and the wireless was working normally, I've updated everything it asked to update, rebooted a few times due to some of the updates. Today when I turned it on it was connecting normally to the router, though when I opened mozilla or tried to ping the router IP on the network tools neither have worked. Couldn't open any site on mozilla or ping any ip although it says I'm connected to my wireless router as it would normally. When I open into the XP my firefox there works just fine.

I'm unable to connect to a particular home wireless network under Fedora 9, although I can connect to it using WinXP on the same machine. My Fedora installation is able to connect to my college's unsecured wireless network, so it's not a driver issue I think.It seems to be an authorisation issue, as I'll describe below, but there's one other thing that's bothering me. The SSID for the network I have problems with is for some reason not listed in Network Manager's drop-down list, nor is it in the output of iwlist wlan0 scan. But I'm pretty sure it's not a "hidden" network - I don't know exactly how those work, but I helped the owner of the wifi network in setting it up, and don't remember doing anything that would make it hidden. As far as I can remember, Windows found the network automatically without having to be told the SSID. What's the best way to confirm whether it's a hidden network or not?
Anyway, I try to connect by selecting connect to other wireless network in Network Manager, and entering the SSID. As far as I can tell from the error messages below, the machine does contact the network and attempt to connect, but I'm not authorising myself properly. That may be a completely wrong diagnosis, but hopefully someone can see from the below info whether it's correct or not.I'm not sure which option to use for "Wireless Security": at the time we set up the network, it gave us a Hex WEP key of 26 characters, which is 104 bits. But none of the options in Network Manager's list match that. Here are the options it has, and the error message I get with each one:None - if I select this, it fails to connect, with no error message.
WEP 128-bit passphrase - if I select this and attempt to use my 26-character WEP key, it brings up a new dialog, saying "Passwords or encryption keys are required to access the wireless network [SSID]." It has a drop-down box labelled "Wireless Security", but this time the only option is "None", and the connect button is disabled, I can only click cancel.
WEP 40/128-bit hex - as above.
WEP 40/128-bit ASCII - The connect button is disabled when I try to use the WEP key, as the string is too long. Despite the fact that it says 40/128-bit, it actually accepts 5 and 13-character strings (40 or 104-bit). Since I've got a 104-bit hex key, I tried converting it to ASCII, but it consists of mostly unprintable characters, so I'm not sure there's any way to actually enter it into the textfield. I might have done something wrong here, so I've put my code below to see if anyone can point out a mistake.
LEAP - requires a username, not applicable here I think. Windows doesn't need one, and we don't have one from when we set the network up.Dynamic WEP (802.1x) - requires username, private key and various other things, all N/A WPA & WPA2 Personal - Brings up a dialog with the same text as for "128-bit passphrase", but this time "WPA & WPA2 Personal" is the only option in the drop-down list, instead of "None". It asks for a password, so I just enter the hex key again - now it asks for the password for the Gnome Default Keyring, which I don't think I've ever set up. Don't know if I can go any further with that, but my understanding is that since we were given a WEP key when we set up the network, WPA will be N/A.WPA & WPA2 Enterprise - as Dynamic WEP. N/A.Hopefully that's enough info that someone can help diagnose the problem. Some of the behaviour of Network Manager described above doesn't make sense to me, and I'm wondering if it's buggy.

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:

SSID: Internet@Sea
Mode: Infrastructure

I am trying to get my Linksys wireless adapter (WUSB11 V2.6) to work under kubuntu /ubuntu.
I am still not able to connect. I believe that I am overlooking or not understanding something.
This is a walk-through of steps I have taken. I can post log files or command outputs as needed.
lsusb shows my adapter, I checked at one point and saw the log file said it needed the firmware from at76c503a.berlios.de so I downloaded the at76_usb-firmware.tar.gz file and copied the at76c503-rmfd.bin file to /lib/firmware and ran chmod 755/ chown root:root as the instructions said.
I then ran rmmod -f at76c50x_usb followed by at76c50x_usb. iwconfig now shows my linksys adapter as wlan1. I use ifconfig to bring the interface up and then set the essid (not hidden) with iwconfig. I then use dhclient to try and get a dhcp address, but no luck.
I have tried setting the wireless mode to managed and setting the ap with the cell address of my wireless router. Still no luck. I continue to the get dhcp no offers report.
I have read that I need to shutdown network-manager if configuring by hand. I did this with service network-manager stop. it doesn't seem to get an address either after this.
Checking the output of messages, kern.log and syslog I get wlan1: link not ready and if I set the ap by hand. I get that it can not associate
Here are some other things that I have noticed and wonder if it is a problem:
lshw shows my wlan1 interface, it shows a loaded driver but gives firmware = N/A (this is after copying the firmware file to /lib/firmware) (log files seem to indicate firmware version)
After setting the ap manually with iwconfig, iwconfig output still shows that the access point is not associated. I am not sure if it is supposed to show the cell address after manually setting it or only if it is connected to the router.
I am running kubuntu 10.10 and I am trying to connect to an open router.

When i give the following command iscsiadm -m discovery -t sendtargets -p 192.168.2.13it only gives me one line output which is:192.168.2.13:3260,1 iqn.2006-01.com.openfiler:tsn.03821172572cNone of the mapped LUNS gets identified neither it shows me any message that it is connecting. I have setup CHAP in openfiler to accept an incoming user plus gave access to my OEL server.Any feedback is helpful. If you need the contents of /etc/iscsi/iscsid.conf file let me know

I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

I managed to install the driver for a Dlink DWA-130 (is a ver. E) and it appears that the computer recognises it. It also sees nearby access points. But, when I try to connect to my home network it asks for the wpa password over and over again after attempting to establish a connection. I'm using 9.10 and installed the driver by using ndiswrapper

I have managed to create an Ad-hoc network on my Ubuntu box as my university doesn't have wi-fi and I need my Ipod touch & wireless printer to be connected most of the time.
Now I managed to get it all setup working perfectly of which was of a relief yesterday - However today I faced a problem that is still baffling me.
I booted up Ubuntu today and managed to connect to the web via eth0 but my wireless seem to take ages to connect. Eventually it popped up with the authentication prompt where I inputted the password. (several times, it kept coming up ) However I had no success connecting then. I tried clicking on the box 'Available to all users' and the next time it tried to connect it just took an age supposedly connecting and eventually failed saying the wireless disconnected. What is strange is that my Ipod touch can connect with the same password being used almost immediately yet ubuntu cannot

I have an IBM R51 laptop which I would like to run on ubuntu (as I'm currently running Maverick on my Desktop and like it very much)I have run the liveCD and everything runs OK except for the wireless network, which although it detects my wireless network, will not let me connect. I have edited the wireless connections with my SSID, (WPA) password, etc, but when I try to connect it will not connect.I have also tried this on an unsecured wireless network with the same result.Running lshw -c network shows the following information:

Before I explain my problem:This is my first post so I do apologize if this post is in the wrong category.Also I would like to apologize for my bad English because my native language is Dutch. I know there are allot of the same topics. but I can't find a right solution for my problemMy problem:After using Ubuntu 10.04 for a while I decided to upgrade to Ubuntu 10.10. After the upgrade and restart the problems started.
I wasn't able to connect to my WPA secured network. This was because there was no network in the list to connect to. I installed ndiswrapper, and installed a Windows driver. Blacklisted the old one and yes. This worked. Then the next morning exactly the same problem. I tried to repeat the same process. To bad. This time it didn't worked. I removed the old driver from the blacklist. and tried to update. No luck at all.I searched the forums. I figured to get a list with networks. but when I click mine and enter the pass-phrase it says it's connecting but keeps asking for the pass-phrase, then eventually disconnect.lsmod

I have 2 systems running ubuntu - 1 Karmic and one Lucid - that I am having problems connecting to my wireless network with. On both systems I am trying to use the same USB wireless dongle - a Linksys Wireless G 2.4Ghz 802.11g. On both systems it picks up my network (amongst others) but will not connect. I try to connect, enter the password/key and it processes for a little while an then just comes up with "You are now disconnected...".
I have a BT Homehub (gen 2 I think) which is set up to use WPA/WPA2 (from memonry). I did try downgrading it to WEP and got connected (only tested on one machine) but dont much like using a less secure system.
So I fall upon the mercy of those who are better than me to try and guide me through this. I have looked into it on the forum but couldnt really get my head around the problem.
Give me some info on where to start and how to diagnose the issue?
Just in case anyone wonders - we have a laptop running karmic (im posting this on it now) that has no issues connecting so the network is accessible. I assume the problem I have lies with the linksys adapter and the software using it.

Linux-user, but this has got me scratching my head. I followed this on how to install and configure the DWA-140 to work with Ubuntu 11.04, and "iwlist scan" outputs all of the networks. When i try to connect to my network however, the icon up in the right corner with the signal bars just keeps on going until it prompts for a password to join the network. I enter the password and it goes on for some time, and then it prompts me for the password again.
I'm using a D-Link DIR-655 with the "Only N" mode active. It works fine on other computers (Windows, sigh) but not on my Ubuntu one.

I run Ubuntu 9.04 on a Toshiba NB205. I am suddenly having trouble connecting to the internet using my router or my cable modem for that matter. The weird thing is that I can:(1) connect to other networks just fine, and(2) my router/internet connection work fine when plugged into my desktop.I can't connect whether I'm plugged in with the ethernet cable directly from my modem or from my router, although both work fine when plugged into my desktop. Basically two green lights show up on networkmanager but it doesn't go from there to connecting.So the usual troubleshooting of moving the wires around and trying to connect like that just suggested that my laptop doesn't connect on the one router/internet connection that I happen to need.
sudo ifconfig
gives:
