Ubuntu Networking :: Wicd Unable To Obtain IP Address?
Mar 12, 2010
I have just installed Ubuntu 9.10 (64 Bit) and I'm trying my best to get this Linksys WMP300N wireless adapter to work.I have searched and gone through a number of threads here with some level of progress but I still can not get this to work.Adapter info is BCM43XG [14e4:4329] rev 01I have installed driver bcmwl5.inf using ndiswrapper and ndisgtk.I had absolutely no success trying to use network manager applet so uninstalled it and went with Wicd instead which at least sees my SSID network with a strong signal.My network is encrypted using WPA and I entered the passphrase which seems to pass authentication but it keeps trying to get an IP address until finally it just tosses a failed message.I feel as though I'm really close but it just won't connect.
iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
I needed to get a wireless adapter for my desktop PC so I went to newegg and looked around to see what PCI-E cards they had available. I came across a Encore one that uses the realtek 8192CE chipset. I confirmed before I bought it that it is supported in the kernel as of version 2.6.38. I am running Slackware 13.37 and I compiled a new 2.6.39.1 kernel and after I rebooted the kernel I checked lsmod,iwconfig, and ifconfig and confirmed that all the correct modules are loaded and the card is recognized by both iwconfig and ifconfig. At first Wicd acted as if there was no card in the system so I checked dmesg and found that I was missing the firmware for the drivers. I went to the realtek sight and downloaded the drivers from there and got the firmware and copied it to /lib/firmware/rtlwifi and now wicd recognized the card and finds my networks. But whenever I try to connect to my network I get an error saying "Can't obtain IP address". I have googled around and can't find any clues on this. The only thing I have noticed is that the activity LED is not working which leads me to believe the card is either turned off/or not powered on. The light works fine in Windows 7. The network I am connecting also uses WEP. I am having no trouble connecting in Windows so I know the card works.
I just got a AWUS036H Alfa Network Adapter but there's like 10 folders on teh CD that it comes with, and there's read me's in about all 10 of'em, i have no damn idea which one to install. I went ahead and just did ifconfig wlan1 up and brought the interface up, went to wicd network manager and added wlan1 to wireless adapter
when i try connecting to my wireless router, it says resetting Ip ddress, something else with the configuration file, then obtaining IP address... it just hangs there for about 2-3 minutes and gives me an error... anyone else know how to set up this adapter?
I just installed ubuntu 10.10 on my laptop Dell Inspiron 1525. Wireless internet is not working. I installed wicd network manager and I am able to see the available wireless networks. My wireless connection is encrypted. I have tried all encrypted options with the key but no avail. It says "Cannot obtain an IP address" after validating authentication.
But i can under an alternate profile. Running ubuntu 10.04 and cannot seem to pin point the problem. When I was doing some looking into it, it appeared that the wpa-supplicant.conf wasn't where the man page indicated it should be. ie /etc/, but then it wouldn't or shouldn't work for the other profile either, right? i tried to post this before but i couldn't find it anywhere.
I am having a persistent problem with getting a wired network connection under a recent install of Ubuntu 9.10. The network manager will show the wired network as 'disconnected' after a restart. This is true whether I am connected directly to my ISP's modem, or through the Linksys router that I usually use.The output of ifconfig suggests that eth0 is not being assigned an IP address:Code:I have reached the limits of my own ingenuity.
I believe I have the wireless card installed properly and wicd sees the router. When I try to connect I get an error "can not obtain IP address" Output from iwcongif and lspci is.
dillan@dillan-desktop:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions.
I'm using Ubuntu 9.10 and I recently changed certain settings of my router. After that ubuntu isnt able to obtain IP address from this wifi network. I've tried to connect with win 7 and OS X and both of the OSes are able to connect to the same wifi network. I tried to connect ubuntu to another wifi network at school and it connected successfully.
I'm using Ubuntu 9.10 and for a while I had no problems connecting to the internet through the wireless network. But recently, my wireless connection started disconnecting regularly. Following an advice I found online, I installed linux-backports-modules-karmic, but after a reboot the wireless device stopped working altogether - it had lost its driver. Since then I managed to associate the device with Broadcom's STA driver, which I had been using before. But now, the wireless device cannot connect to the internet anymore. The network manager's output to /var/log/syslog indicates that the device cannot obtain an IP address. When I run code...
The IP address acquisition problem I reported earlier has returned, and I am stymied. To recap: Ubuntu 9.10 would not obtain an IP address via a wired Ethernet connection. I resolved the problem at the time by configuring eth0 in /etc/network/interfaces:
Code:
auto eth0 iface eth0 inet dhcp
and disabling Network Manager in Preferences > Startup Applications.After a powering down the PC today, the problem has returned. It appears that dhclient cannot obtain an IP address. This is true whether I am connected to the router (a Linksys WRT54G running Tomato), or directly to the DSL modem. When my usually wireless Ubuntu 9.10 laptop is wired to the router, it obtains an address almost instantly. I have made no changes to the network configuration since January. I have tried to keep current on Ubuntu updates.
Code:
jgb@alienware:~$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:30:1b:ac:5b:9e inet6 addr: fe80::230:1bff:feac:5b9e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I'm using Ubuntu 9.10 on a Lenovo ThinkPad T61 using an Intel PRO/Wireless 3945ABG. My laptop's ability to connect to a wireless network stopped last night, and I'm not sure why. It's definitely something on my end, as my roommate can connect to the internet on a Windows box. I can wire in without a problem, but that's a pain and my Ethernet cable got lost in the shuffle when I moved back to school. I've been able to get into this network before and nothing about it has changed. I've been able to hibernate and restart and such and nothing has ever needed to be reset.
The router's a D-Link WBR-2310. Wicd and Network Manager see the network (I'm back to using wicd) , but wicd appears to get stuck at "Obtaining IP address..." and says "Unable to connect: Cannot obtain IP address". I know my password is correct (I set up the router and I'm the CS undergrad in the apartment so I manage it), lspci sees the wireless card, ifconfig and iwconfig return information about the interface, dmesg|grep wlan0 doesn't seem to have anything terribly out of the ordinary, but here's that output:
Code: allyanncah@taliesin:~% dmesg | grep wlan0 [ 23.514202] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 36.609016] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 38.756143] wlan0: direct probe to AP 00:24:01:cb:4e:7e (try 1) [ 38.758791] wlan0: direct probe responded [ 38.758796] wlan0: authenticate with AP 00:24:01:cb:4e:7e (try 1) [ 38.760587] wlan0: authenticated [ 38.760609] wlan0: associate with AP 00:24:01:cb:4e:7e (try 1) [ 38.763318] wlan0: RX AssocResp from 00:24:01:cb:4e:7e (capab=0x431 status=0 aid=1) [ 38.763322] wlan0: associated [ 38.765502] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready .....
I've tried: - reinstalling wicd - uninstalling wicd and installing network-manager - restarting - shutting down and booting back up - restarting the router - sudo /etc/init.d/networking restart - taking the interface down and back up with ifconfig
I haven't changed anything recently in regards to my wireless card, and all the fixes I've tried are things I've done before without an issue. The only thing I'm wondering about is if doing a hard reset might have broken something (I know this is a cardinal sin, but there's a whole 'nother problem I haven't been able to fix with the OS hanging every once in a while over a VPN daemon when it tries to shut down or restart -- I've left it for hours to see if it actually gets anywhere and no luck, won't do a soft reset). I'm nervous about reinstalling the driver just because I've never had to do it and drivers are a finicky business. I imagine there's a config error somewhere?
I had no luck with network manager and i was surfing the net and it said wicd was better so i installed that and installed 1.6.1 But it was not obtaining an ip address
So i searched again and ppl said that its a problem with 1.6.1 and they said 1.5.9 was better. So i installed wicd 1.5.9 and its still not obtaining an ip address.
The router is unencrypted no security, ppl suggested trying to set a security on it so i tried WEP and when i do that it gets stuck on trying to authenticate the key phrase.code...
When trying to connect to a wireless AP, neither wicd or wifi-radar are able to obtain an IP. With wicd, a string of various hex/dec characters flow by, with an eventual error. This happens with both WEP and unencrypted APs (- the hex/dec). With wifi-radar it simply fails, but not every time. NetworkManager connects with zero problems every time; though I prefer to not use NetworkManager, so please spare me of such replies. Someone please tell me why there should be only one wireless manager in Ubuntu that works? I have used wicd since before gutsy gibbon, and it always worked fine until the last two versions, Lucid, and Karmic. What is occurring in Ubuntu which over time breaks these excellent applications? I have tried this with four different wireless cards, and all suffer either identical or similar issues. Those chipsets are Broadcom, two RealTeks, and an Intel.
I really wish to emphasize that this post is not a request for a lecture on why I should use only NetworkManager, or why I should go find another distro. With something like Linux, maybe we could push a little harder, and have maybe say, two, wireless managers that actually work? I would honestly like to see more than two, but one is not enough. It baffles me a bit why new versions of Ubuntu mangle some perfectly good applications, but not others. In IT, surely networking, IP4, WEP, basic wifi technology, etc. has not changed so much that every six months whole new programs should need to be written to connect to a wireless access point. Nor should old ones need much tweaking. What's going on? With such boastings of repositories abundant and brimming with free apps, why does anyone want to make NetworkManager the only app that works?
Linksys router and an acer aspire one. I have updated to the 9.10 netbook remix and the laptop associates with the router but will not pickup dhcp. If I specify an address then the machine looks like its connected but will not go to a website. I manually inserted dns but still nothing. So I updated to linux-backports-modules-karmic-generic linux-backports-modules-wireless-karmic-generic Still will not use DHCP , I to am using ethernet at the moment. It was working before the update.
though method of editing /etc/network/interfaces worked for me i have decided to get gui work.i have installed wicd, i set wep key for connecting to my network. when i'm scanning wicd find my network. but i get error "couldn't obtain ip address". when i dived into logs i found that there is some problem with wpa_supplicant. here is piece of log:
I am having a problem getting a wireless network connection on my DELL laptop running CentOS 5. I have no problem getting a wireless connection when the laptop is booted in Windows XP. I also don't have a problem when booted under CentOS 5 and there is no authentication setup on the wireless router. I only have a problem when I setup authentication. The router wireless log shows the PC connectinng, authenticating, and succeeding authentication.I am using the Broadcom Hybrid-wl wireless driver.
I just installed ubuntu 10.10 on my laptop Dell Inspiron 1525. Wireless internet is not working. I installed wicd network manager and I am able to see the available wireless networks. My wireless connection is encrypted. I have tried all encrypted options with the key but no avail. It says "Cannot obtain an IP address" after validating authentication.
I don't know much about networking... I have Debian Lenny and use wicd to connect to my wireless. Yesterday, I changed my ISP and now I cannot connect to the wireless signal, only to the wired. It had happened before that it took some tries to connect to a new network, but, after a few tries, it would connect. And then it would always connect at once. But now, it always gets stucked on the obtainment of the ip address. The same routher gives me a perfect wired connection... My wife has Ubuntu and she got it working right away, so it's not a password or router problem...
I am trying to use nm-applet with Arch/Openbox/tint2. I can't use wicd-gtk because wicd won't work with ad-hoc networks. I have tested nm-applet in Ubuntu/Openbox/tint2 and it works fine.
The error message is: Code: [esteeven@piccolo ~]$ nm-applet ** Message: applet now removed from the notification area
I have an open WEP wireless internet connection with a security key. KNetworkManager can never obtain an IP address from my wireless router, but I know that the router works because Windows can connect correctly and Ubuntu's NetworkManager can connection correctly. Does anyone know what is happening? KNetworkManager just asks for my security again and again and again after it fails to connect.
I'm running an embedded Linux kernel, and I want to obtain a real memory address from user space. After goggeling a little, I found that the only way was to use mmap to access /dev/mem. But I never used mmap. I want to load a program in memory, in order to make it available from another processor, that has access to the DDR, but not to the flash memory where program is stored. Here is the code I use:
Code: // Open file and get its size FILE* program = fopen(argv[3],"rb"); fseek(program, 0, SEEK_END); long program_size = ftell(program); fseek(program, 0, SEEK_SET); // Prepare memory to copy it in void* program_address = malloc(program_size+1); FILE* memory_stream = fmemopen(program_real_address, program_size + 1, "wb"); [Code]....
I am unable to obtain a blank CD-R to burn the ISO. I have it installed through WUBI but due to the size restriction to 30Gig it makes it completely useless to me. I gave my CD away that I got free from shipit and they wont let me get a new one. I have an external HD formatted to NTFS with files on it that I can't lose, they are very important. I might buy a disk later but right now my funds are tight due to bills and such. I use Ubuntu more than Windows, actually Windows is pretty much never used on this machine and due to issues with it I am unable to use it.
I am using ubuntulite for an old pc. The speed and performance is excellent!! But there is one problem. I am not able to edit my ip address. The computer is on lan and i have to assign a static ip to my system so that it connects to the net. The gui is not working. So I want to edit the ip through the terminal. How to edit the ip throught the terminal<command line>.
I'm using Ubuntu 9.10, and I want DHCP to assign an IP address automatically. I can ping my router, and get a reply. I just have no idea how to do this.I'm trying to get my Ubuntu machine onto my Windows network.
So I got Ubuntu 9.10 on my laptop working really neat and wanted to upgrade my desktop to 9.10 as well. So I reinstalled Ubuntu there and now I can't connect to my network anymore....
I have a usb wireless adapter (currently Sitecom as I bought a new one today to hopefully fix it, but ended up at exactly the same problem as with my old adapter). The network manager I'm using now is Wicd since some topics I was looking through were about malfunctioning GNOME network-manager (which I removed) and suggested to try this. The GNOME network-manager kept prompting to insert my WEP network key which was a correct one. When I removed all security from the network it didn't prompt anything anymore but just failed to connect. The Wicd network manager is so nice to tell me that it cannot obtain the IP address however, so I suspect that this is my main issue... but I have no idea what I can do about this? Tried using a static IP and then I get the message "Connection failed: Could not contact the wireless access point."
I feel powerless as my knowledge here is just lacking..
I recently setup motion on one of my computers with a USB camera. On that computer if I type [URL] I can see my live video. If however I type [URL] on that computer or any other on my wireless network, I get a page cannot be displayed. I checked that UFW was disabled and I am able to ping the motion computer from any other computer on my network. Also I am not sure if it matters but I do have apache installed on my motion computer as well. why I cant view my live video from different computers I am using Ubuntu 10.4 on all computers
I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains). The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
I want to force my IP address to 192.169.0.99but my router always allocates me 192.168.0.2I have attached a screen showing my settings.I'm using the broadcom wireless card to connect to the router?Any thoughts, I have tried to change the setting with and without the network manager.
