Ubuntu Networking :: Connecting To Wireless Network - But No Access
Aug 7, 2011
I have a fairly new install of 10.04 on a Dell laptop (about a week). Everything was running well, connecting wirelessly to the interneet through my home router (WPA/WPA2). Today, for some reason, I lost my connection to the internet. The network manager tells me I'm connected to my router, but all the lines on the wifi indicator are gray and there is no internet access. I reinstalled the 2 sets of packets for my BCN4312 (bcmwl-kernel-source and b43-fwcutter ), but no change.

I would share my long awaited success with connecting my ubuntu laptop up to my universities (University of Western Sydney) wireless network. The rumors appeared true and they have finally implemented 802.11x authentication instead of that horrible java app netdirect. I am sure you've been cursing at its erratic stability. There is no linux documentation for airUWS-Lite nor anything more imformative than there windows/mac point and click steps found at [URL]. However with a few simple clicks you can have stable working connection.
When connecting make sure you have theses settings.
Security: WPA & WPA2 Enterprise
Authentication: Protected EAP (PEAP)
#This is the settings that does not present itself correctly
Anonymous Identity: leave blank
PEAP Version: Automatic
Inner Authentication: MSCHAPv2
Username: <YOUR 8 DIGIT STUDENT NUMBER>
Password: your regular password

I noticed that it takes a couple more seconds before Ubuntu connects to my wireless network when it wakes up from sleep. I didn't have this annoyance when I was using 10.04, and only appeared when I upgraded to 10.10. It takes about 5-7 seconds before it indicates that it's connecting. When I was using 10.04, it only took a maximum of 2 seconds for it to indicate that it's in the process of connecting to my network.

i just installed Ubuntu 11.04 64bit on my desktop. i have a TP Link TL-WN321G (Ver 4.0) wireless usb adapter to connect to my wireless network (i used to use it with Windows XP).As expected (i'd read up a bit before installing Ubuntu), the adapter was autodetected - i could see my wireless network listed in the networks list dropdown, and lsusb showed it too.lsusb identifies "Bus 002 Device 002: ID 148f:2070 Ralink Technology, Corp. RT2070 Wireless Adapter"But i cannot connect to the network. When i select my network, it keeps trying to connect, but never succeeds in connecting.
i tried going through the forums for possible solutions, but most of them deal with how to get it working when the adapter is not detected, or when networks are not shown. Or they are for older Ubuntu versions.i use the same wireless network on my laptop (Ubuntu 9.04), and it has a WPA & WPA2 Personal security, with a password, which i've configured in the desktop as well.

I have a wireless router, but my desktop computer is connecting to it, or maybe to the modem, by an Ethernet cable. It has a built-in wireless card, so just as an experiment, I tried to connect to my network wirelessly. It didn't work. And not only did I not get any internet connection, I can't get any internet through the wired connection either. The internet works fine with Windows Vista (I'm dual-booting), as well as when I boot up Backtrack off of a Live DVD. I can still access my router's config page by going to 192.168.2.1 on a web browser, but I can't access anything else.

In setting up wireless connections I have ran into an array of problems. First, when I installed the new OS on my laptop I had to get the correct drivers and firmware for it to display and connect to any connections, had no problem here connecting to a secure wireless network (WPA or WPA2). I then installed Ubuntu on my desktop and had to find the correct driver for the Netgear WNDA3100v2 USB adapter, got it all installed with the Windows Wireless Drivers tool or w/e it is. This made all the available connections come up. I tried connecting with the WPA password I was given for the network and will not connect.
I had the guy managing the network change the one I connect to, to a WEP Passphrase Shared Key thinking this would solve my issue, still nothing. And also in doing so, now my laptop will not connect to the wireless network using the Passphrase. I do not want to go back to Windows, and I will be getting rid of my Lan connection soon so i need a solution to fix this wireless connection problem.

I recently downloaded and installed CentOS 5.3 DVD media.The media check passed. I proceed to install the operating system sucessfully. After installation, all my hardware is recognized, when compared to CentOS 5.2. Anyway, when I attempt to connect to my wireless network that uses either WEP/WPA/WPA2-- I get an error message that I cannot recall (it basically only came up when I entered the key) However, I can connect to my wireless network when it is unencrypted and no open/shared key is needed.I would like to be able to connect to my wireless network when
FYI: I am using a RealTek RTL8185 Wireless Driver.Also, I use CentOS as a workstation.

I'm having problems with my wireless card. The network manager won't allow me to turn it on. It is working in windows and in ubuntu, but I can't get it to turn on under fedora. I'm using a Lenovo B570 laptop and it uses the Centrino Wireless-N 1000 for wireless.

I am trying to do a command line installation.Finished the installation and my wireless card wasnt working.Did a "sudo ifconfig wlan0 up" and got it working.But for some reason wireless-tools is not installed thus I dont have iwconfig, iwlist, etc.The wireless works and connects fine off a liveUSB.So I am going to give info from this liveUSB run and maybe someone can suggest how I can set the right settings on the Command Line Installation I presume in the etc/network/interfaces.

So I finally successfully installed Ubuntu 10.10, but I can't access my home wireless network. I dual booted with Windows 7, and it detects my local wireless network, asks for the key and connects correctly. In Ubuntu, I have to plug in an ethernet cable to access the internet (like I am now). Ubuntu doesn't detect the network, and I tried "Create New Wireless Network..." up the top right, but it doesn't connect.

I have had a heck of a time trying to get my laptop running ubuntu to connect to my home network. I have managed to get it to work at my university which would seemingly be more difficult than getting it to work at home, so I know for a fact it isn't a hardware or driver issue. If I try to connect via ethernet cable from my router, it detects that I connected the cable but says "disconnected" and never lets me connect. If I SKIP the router and go from my modem directly to my laptop via ethernet cable it works great.
Using the wireless network tool I can see all of the wireless connections in my area. When I go to connect to my network it prompts me for the WEP key and when I enter it and hit connect it just keeps cycling and eventually times out and finally again prompts me for my WEP key. I know this network works as it works just fine on my Windows 7 partition. Another interesting note - both my wireless and ethernet connections both worked flawlessly and stoopid easily on the live cd but don't after the full install.
If I manually enter in the information for my wireless through IPv4 settings and enter in the Address,Netmask and gateway I can connect to my network - but then I have no active internet connection. Same deal with my wired connection. Is this because choosing this manual method grays out the DHCP?

I am trying to connect to the college campus wifi network, but having difficulties in Linux.I am dual-booting Windows 7 and Ubuntu 10.10, and I use Google Chrome web browser on both. When I boot into Windows, my laptop connects to the network (as I can see from the taskbar icon) and I can (and currently am) connect in Chrome.However, in Ubuntu, it connects (or so the icon indicates) but Chrome doesn't load any pages.The campus network is unsecured, but once you open the browser, you are prompted with a log-in page (student ID and password) to actually connect.Here is my output for iwconfig:
Code:
wlan0 IEEE 802.11bgn ESSID:"sjsu_campus"

Bit Rate=54 Mb/s Tx-Power=20 dBm

I'm having some trouble connecting to the wireless network here at home. The PC has a Linksys WMP600N wireless network card, which works fine under several versions of Windows. In Opensuse however, I cannot get it to find the network. Even though my laptop is right next to it, which has perfect connection to the network. The router is a Linksys WRT610N.
I've tried running iwconfig and iwlist scan in the terminal, but the scan returns no results and iwconfig indicates it does not have a connection to a network. I've turned off IPv6 as I read this can sometimes cause issues. I've also tried issuing the computer a static IP address, figuring the DHCP might be causing problems, but all to no avail.

since a few weeks I have a problem connecting to other hosts when I'm using another wireless network, which has a different DNS IP than I have in my network. I have to change /etc/resolv.conf to change the nameserver. Can NetworkManager control the nameserver? If yes, how?

I have had this configuration at home for years, but I just changed my line provider and I cannot get it to work.
I have a desktop machine with two ethernet interfaces, eth0 and eth1. Etho is connected to the cable modem and that seems to be working fine - well, I'm posting here, right? Eth1 is connected to a Linksys WAP54G wireless access point. I have eth1 set to 192.168.1.240 and the AP set to 192.168.1.245 (the default). The desktop runs CentOS and I have dhcpd running, and I have focused on the dhcpd.conf file, which I have changed many times. Here is the latest incarnation:
Code:

I can connect to my school's wireless network using the standard network manager, but often (not always) it repeatedly disconnects and reconnects every few minutes. Occasionally it also prompts me for the security information again (even after it previously connected successfully).
By running iwconfig when it's on the fritz, I can see that it's often switching access points for the network - which is what I think is causing the problem. It disconnects and reconnects even when the signal strength for the current AP is fine, and it will often switch to an AP with a weaker signal strength.
$sudo lshw -C network

I am unable to access wireless network from my notebook. My configuration is Dell i5, 4GB RAM and 1397 W-LAN and I have F13. I can still access Internet through Ethernet using a LAN cable but the network monitor doesn't show list of Wireless networks which my room mate's windows 7 machine easily detects.
If anyone needs more info please provide me the steps to perform to find that out

I am having some trouble getting my computer to connect to my wireless network. There is a wireless icon in the system tray. When I click on the icon I get a list of SSIDs associated with available wireless networks. To connect to one of of those networks I move the cursor over the SSID, the SSID is then highlighted, I select the highlighted SSID, then my computer connects to the selected network.
Sometimes the SSID associated wth my wireless network does not show up on the list. Sometimes it does. Normally the SSIDs on the list are in bold lettering. When the SSID of my network does appear it is in shaded lettering. When I move the cursor over the SSID it is not highlighted and I cannot select it. So you see it is not possible for me to select the SSID of my network and connect to my network.
The computer I am running is a ThinkPad R40. This is the wireless controller on the computer. I got this with "lspci". 02:02.0 Network controller: AIRONET Wireless Communications Cisco Aironet Wireless 802.11b

My wireless is 'almost' working, but frustratingly not quite there. Debian Testing (squeeze). I have two different wireless adapters. Both work flawlessly from an ubuntu live CD in the same machine, connecting to the same unencrypted access point so the problem is not faulty hardware, weak signal, overpowering signal, interference from other AP's, MAC filtering, or anything to do with WPA.
I have loaded the correct (I think) firmware packages for both adapters. dmesg is not complaining about missing or incompatible firmware. I have googled the various error messages reported in dmesg and found that the /etc/Wireless/RT2860STA/RT2860STA.dat missing config file is normal. I could not find anything that I understood concerning the BSS returned, data->length messages but since I see the same thing in Ubuntu (where the wireless is working flawlessly) I assume they are also normal and not related to the problem.
Both adapters can see all the available access points (using iwlist {iface} scan or using gui tools such as wicd, wifi-radar) NEITHER adapter will associate with any access point (and I've tried three different unencrypted AP's so far). I can connect to all/any of these AP's from an ubuntu live CD using the exact same hardware, so this is NOTHING to do with MAC filtering, etc... using 'iwconfig {iface} essid' as root to set the essid "appears" to work, but simple does not set the ESSID on either wireless adapter.
Using the GUI tools (which are only a front end for the command line tools so I have no idea why everyone thinks a GUI front end like wicd will magically work where the command line tools don't!!) I simply wait a long time for "getting network address" before it eventually fails. LOTS of information in pastebin, please make the effort to read it before asking me for things I have already supplied. And please keep any "RTFM noob" or "go back to ubuntu" replies to yourself. I HAVE read the f*cking documentation and I do not want to go back to ubuntu. I just want to get my wireless working in debian.

I just recently switched to openSUSE 11.4 from Ubuntu 10.10 so I am very new to this distro and Linux in general. My question is this.Is there a way to make it so that I don't have to keep entering my root password in order for the OS to connect to my wireless?Every time I login the KDE Wallet Service pops up and asks for my passwordI know that it is there for security and what not but it'd be nice if I could just login and the laptop connects to the point without needing a password every time

I am having trouble getting my wireless card to connect to my network. I believe I have done everything correctly. Here is my wpa_supplicant.conf file:
Code:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
[Code]....
I have never connected to a wpa network using slackware before, so I am not entirely sure how to use wpa_supplicant. I have altered the conf file, then tried dhcpcd and it times out.

I just bought a new USB wireless adapter for my openSUSE 11.3 laptop, a TP-Link TP-WN727N. I can't get the new card to connect to my home wireless network, which is named WRT320N in the screenshot. KDE prompts for the key repeatedly but never connects successfully. Part of the problem might stem from the fact that this laptop now has 2 wireless cards: one build into chipset (PRO/Wireless 3945ABG) and the new USB card. Both show up in knetworkmanager but no clear distinction is made between them visually. Strangely my wireless network shows up twice in knetworkmanager as in the screenshot. Once per wireless card? As my wireless network is N-only I don't see why it would do this.

Just moved over to openSUSE 11.4 (KDE) from Ubuntu, yesterday. However, I'm having some trouble with my wireless connection.
I have a wireless network with a hidden SSID and WPA2-PSK security. I entered all the nescery information into the KDE network manager, but it couldn't find my network. So I ran the usual command:
Code:
su -c iwlist wlan0 scanning essid [My SSID]
At which point, the network manager immediately found, and connected to, the network. However, it seems that I have to run this command (as root) each time I log in, before my laptop will connect to the network. The network manager has no problem find the plethora of unsecured networks as well as those that are secure, but broadcast their SSID.

I seem to be have issues periodically connecting to wireless networks with WPA. It'll work one minute, and then I switch my macbook back on after a period and it refuses to connect again. It's happened on and off on three different networks now.
An example of /var/log/syslog:

I've spent 29 hours trying to figure this out. And I'm about to blow my brains out. Fresh install 11.2. - 64bit but tried 32 bit and same thing. Dell studio 1734. Broadcom wireless and wired. Installed broadcom drivers (b43) through yast. Wired eth0 works. Wireless eth1 works. Surf with Firefox fine. BUT. Kmail will not connect through wireless. Nor can I access repositories through wireless.
Tried blacklisting B43 in ssb no change. What in the hell is going on? I've searched forum after forum and tried everything and CANNOT make this happen.
