Ubuntu Networking :: Cannot Connect To School WiFi - Need Certificate
Oct 28, 2010
At home, I can easily connect to my home network with ubuntu. But at school, things are differently. The wireless security is tighter, and I need more then just my username and password to connect.
(See attachment for Screenshot)
The last two lines, okay, but I seem to need a certificate, and that MSCHAPv2, Anonimous identity. I don't understand what I need to enter in those fields. I only got a username and password from school and that's all I need for windows. So why does Ubuntu want/need more info?
I just installed Ubuntu on my laptop and I found that I cannot connect to my school's wifi network while i have no problem connecting using windows. Also I can connect to my home's wifi network. The details of the wifi network are as follow:
I have downloaded the certifate required and put it in my home directory and selected that .cer when setting up the connection But I still can't connect to it
I installed Ubuntu 9.10 onto my laptop, and having wireless issue. I was able to connect to wireless at home, but cannot at school. Then recently, I reformatted by desktop at home, and now I can no longer connect to my own connection. But yet, I'm able to connect to my neighbor. I considered installing ndisgtk package, but then i thought if I'm able to connect to some connections that means I'm not missing windows driver (maybe I'm wrong ).
I'm at the AirPort. I can't connect with Linux but can connect with Windozzze. In Linux I get: You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number (Error code: sec_error_reused_issuer_and_serial). The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
The airport requires that one look at a login message and agree to its terms before making any other connection: that's what I can't get and can't get further. Up-to-date Slackware, latest kernel (self-built), Atheros wireless chipset, eMachines e725-4250 laptop. I've connected here before, always in Linux.nl. Who's objecting? This is in Firefox the only browser with Javascript I have. What certificate are they talking about? I just downloaded Opera: it works. It detects the defective certificate and asks if I want to proceed. How do I get Firefox to do that? Should I move this message to a different forum?
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 installed Debian sid recently. I installed the B43 driver and wireless is working just fine at home and elsewhere. I can't connect to the wireless networks at school though. There are two networks, one is unsecured (and you have to enter your login details after connecting - I can't connect at all though), the other is secured. I was previously using Ubuntu, with network manager, and I have all my settings the same for the secured network as I did in Ubuntu. In Ubuntu I can connect to both networks just fine. In Debian I can't.
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.
Having played around with ubuntu a fair bit I decided to breathe life into an old thinkpad with a pcmcia wireless card, by following the minimal install instructions and using lxde window manager etc.. Everything works fine apart from the fact that I cannot connect wirelessly. The card picks up and lists connections but whenever I have clicked on a connection the dail spins and then it gives up.I installed network-manager and managed to get nm-applet appearing in the sysTray otherwise I would not even have known there was wireless connections there.
I was thinking there maybe some conflict with another network manager, does this sound likely?
I'm having an issue recently with Ubuntu 10.04 x64. Connecting to my wifi is not working. I believe it is some kind of issue with the router. On Windows 7 the only way that I could connect to the net was by copying the network profile to a usb flashdrive from another computer and loading it mine. The wireless signal just keeps attempting to connect.
I have Ubuntu 10.04 on my EeePC 1000H. I don't use this computer often but it has always worked before... I suspect an update did this to me. I've recently swapped wireless routers but all my other machines have been able to connect to the new router. I can see the SSID and the signal strength is high but when I try to connect to it, it just attempts for a long time then asks me for my password again. I am currently connected to wired network.
I installed Ubuntu 11.04 yesterday and my wireless didn't work so I searched a little and found a way to make it work; Uninstalled bcmwl-kernel-source and installed firmware-b43-lpphy-installer and b43-fwcutter. And it worked. But today I accidentally pressed the "turn off wireless" button on my laptop. I obviously pressed it again and thought it would work but it doesn't. Now I find networks and stuff but I can't connect to them. It tries for awhile and then asks me to enter the password which I do (it is correct) and then it tries to connect for a few minutes again and then it asks me for the password again.

I'm having a problem to connect to the network at home via wifi, open or protected. Using ubuntu 11.04, attached are more details. I've managed to get a successful connection on an open network at work.
I am trying to tunnel through my college's free AP so I can get access to protocols outside of http and https. The school has an in-browser DNS redirect until you log in.The output of "cat /proc/version" on the server OS is "Linux version 2.6.35-27-generic (buildd@palmer) (gcc version 4.4.5 (Ubuntu/Linar o 4.4.4-14ubuntu5) ) #48-Ubuntu SMP Tue Feb 22 20:25:29 UTC 2011" The client OS is Windows 7. What I have done so far is use Proxy Cap to redirect applications to a Putty tunnel connected to the server. Eventually I want to tunnel that SSH connection through my school's firewall, so that I can keep encryption and have a reasonable amount of ease with setup.
I am not particularly educated on the inner workings of the DNS redirecting so I was not sure what to search for. My attempts to connect Firefox over normal http proxies failed and since all ports are blocked besides http and https I didn't attempt any socks or SSH. I have also tried simply hosting the SSH server on http ports with little success. I hope that I can do this without having to purchase a domain, but that's starting to seem like that won't be the case.
i am tryin to connect to internet through wifi. for this i have to connect to router first and then open the web browser to put UN and PW. I am using ubuntu. i know UN and PW. I can connect to router but my(any) web browser cannot open the authentication page.
I just installed the XBMC from the XBMC live CD. I want to configure it in a way to auto-connect to internet. (my router is wpa-password protected.)
i know how to save the password and auto connect to internet from gnome GUI but not how to do it from command line. what should i install, change or configure in order to auto connect to internet? (using command line)
I am running 10.10 on a Toshiba NB255 netbook. Wireless works find for me at home and worked last week at a hotel. At home I just use WEP, and my office network uses WPA. I can connect just fine from my work laptop but not from this netbook. The network shows up fine in the network manager and it asks for the WPA password, but doesn't establish a connection. Every once in a while it will say it is connected and has full strength but I can't ping anything, and within a minute or so it drops again. IIRC yesterday it connected via wireless and actually worked for maybe a minute before dropping at it hasn't worked since. Like I said, this has worked on other wireless networks.
Here is some output from dmesg: Code: [55086.034476] wlan0: authenticate with 00:15:62:ff:6e:89 (try 1) [55086.037598] wlan0: authenticated [55086.037658] wlan0: associate with 00:15:62:ff:6e:89 (try 1) [55086.041880] wlan0: RX AssocResp from 00:15:62:ff:6e:89 (capab=0x431 status=0 aid=4) [55086.041891] wlan0: associated [55089.045810] wlan0: deauthenticated from 00:15:62:ff:6e:89 (Reason: 2) [55089.079974] cfg80211: All devices are disconnected, going to restore regulatory settings .....
So recently we switched Internet Providers. While we had Bellsouth, my laptop would connect to our wireless internet flawlessly everytime. However, we just switched to Charter because it was both cheaper and faster. But now, my laptop will not connect to our wireless. If I hook it up to an Ethernet cord, it connects just fine. I believe they gave us a new modem/router or whatever it is that sends out the wifi signal.
I have tried to connect with this laptop on Ubuntu, Linux Mint, and Backtrack 4. On Ubuntu and Linux Mint, after I enter the correct WEP key, it sits there and tried to connect for a minute or two, but then the window pops up asking for the WEP key again, even though it's still filled out.
When I tried connecting on Backtrack, it told me that it could not obtain an IP address.
I think I have unique problem. I have a d-link DWL G510 rev c.(Austrailian) WiFi card in my pc which is detected as

Now sometimes it detects my wifi router and shows its ssid in nm-applet. but when I try to connect, it tries for 3 or 4 minutes and then fails. for most of time it even does not finds my router.
about 90 percent of the time, i cannot connect to the internet. i click on the icon and select the network, but for some reason, instead of saying, "connection established", it says, "you are now disconnected."
Wireless adapter is working OK because I can connect when network is unsecured, but when I try to connect to the secured wifi it just won't accept the password.
I can see available networks in Network Manager but can not connect. No error messages, just no connection.
Is there anything I can try to enable connection to the WEP secured router?
Just reinstalled ubuntu 10.10 x86 on an old laptop. The wireless doesn't seem to work and I have no idea how to solve this.
In gnome I can see NetworkManager display the network ESSID. I have entered the key but no success, it tries to connect and then times out after about 1-2 mins.
I have tried to change the encryption from WPA2, to WPA to WEP to nothing but the same issue.
In a terminal/shell running ifconfig/iwconfig I can see eth1 as the networkinterface.
How can I investigate this further. If there was an IRQ collission or something it would not be showing the ESSID right?
I have installed both win7 and ubuntu, and with win7 i can easily connect to wifi in my arrea. Why i cannot i connect with this? I've installed the system with wired internet, and i'm trying to connect to a unsecured wifi.
Basically the wifi on my Dell D600 laptop works fine if I stick with kernel 2.6.35-28. But it won't work with recent versions such as 2.6.38-8 or 2.6.38-10.
The network manager icon in Gnome is displayed as an empty pie (i.e. no curved signal bars). Clicking on he icon does not give me an option to connect to my wifi ap. If I connect a network cable, the icon changes to twin arrows and I have wired network access.
Running:-
Code: cat /sys/bus/pci/drivers/ipw2100/*/rf_kill returns: 0 ...showing that wifi interface is not switched off.
I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).
However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?
