Ubuntu :: New Adapter - Unable To Obtain IP Address
Feb 9, 2010
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 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 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 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]....
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 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.
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.
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've just arrived at uni and to set up my wifi apparently I need my "media access control which is listed as the phsyical address for ethernet adaptor local area connection." on windows you can find it by using the command ipconfig /all but that didn't work when i put it into terminal.
Is it possible to create virtual network adapter on the same physical network adapter? or How to give or have multiple MAC Address to the same adpater? I m working on centos 5.3.
Installed CentOS 5.5 on VMware ESXi server running vsphere 4.1. Installed fine and picked the E1000 network adapter. But can't get the adapter to become active and pick up an IP address. Has anyone done this before? I can't get it to work. When i was testing CentOS out i used VirtualBox and worked fine using bridged networking but just can't seem to get this network card working.I've put some pictures of the config i've got.http:[url]....
Im currently unable to install a wireless USB network adapter because it requires an installation which can only be done with a cd and im not sure how to install the software to run the wireless adapter.
Just received network adapter and unable to install. Belkin service was useless. Moved computer, running point to point on the LAN. Searching for a compatible driver and/or means of installation. Poor connection with Clear and modem's on top floor, Belkin's a good option.
I have just installed Ubuntu 10.10. It is great and all but I am not able to get my wireless adapter working...it is a cheapo one and I have found different tutorials around the internet trying to get it to work...to no avail!
I'm unable to use Cisco Linksys Wireless-G USB adapter - Model No. WUSB54GC ver 3.

Tried startup with device connected, no success.
Read some threads which generally correspond to version 2 of the device.
It probably uses Ralink chipset(cmiiw). I neither have Rt73 nor prism2_usb installed, confirmed by lsmod.
I can't post messages, I think something is wring with my internet.Anyway, I'm gonna copy paste what I've been trying to say...I just bought the TP-LINK Model No. TL-WN821N. It's an atheros. And I was wondering where can I find the drivers for Linux. It only includes drivers for Windows.
I don't have much experience with networks,I found this website,

I got stuck in the patch section, I don't know what they are trying to say. They are using
configuring my ASUS USB-N13 Wireless-N Adapter I was able to get the drivers installed as per the instructions I found in the forum but I'm not sure how to get the ASUS USB-N13 Wireless-N Adapter to be recognized by the drivers and how to configure it to connect to the Internet I tried following the instructions it came with but I did not understand the steps to set it up it was like chinese to me no clue what it said I am running Redhat Linux 9.0 on the laptop
i am using fedora (2.6.35.6-45.fc14.i686), i am not able to configure the usb based wireless adapter, its DWA 125(Dlink) uses ra chipset.

i have got the driver loaded with the help of modprobe, still unable able to make it right. when i use system-config-network - wireless - no sign of RT2870.
When a second network adapter is fitted, the boot script fails to configure the default gateway. Here's from /var/log/messages with DEBUG_ETH_UP="yes" configured for the boot script Code: Feb 13 10:22:23 ps1 logger: /etc/rc.d/rc.inet1: /sbin/route add default gw 191.168.1.1 metric 1 Feb 13 10:22:23 ps1 logger: SIOCADDRT: No such process
After boot the same command failed with the same message when done by root logged in via ssh but succeeded when run from the console After removing the second network adapter, the boot script is able to configure the gateway.
EDIT: or not. The problem now seems intermittent Now with only the onboard network adapter the same "SIOCADDRT: No such process" error is logged during boot and the "/sbin/route add default gw 191.168.1.1" command fails at the console too. Am experimenting with disabling the onboard adapter and fitting the NIC.
EDIT 2: definitely intermittent. Just rebooted with no hardware changes; same error during boot and route -n showed no default gateway but "/sbin/route add default gw 191.168.1.1" worked.
