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.
View 2 RepliesI 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.

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.

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...
View 4 Replies View RelatedI'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:

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.

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?
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.

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.

Running kubuntu karmic, kernel 2.6.31-19, on Asus EEE PC 1000.
WICD 1.7.0. hangs on "wired connection: obtaining ip address...". I have downgraded to 1.6.2 and 1.5.9, but this did not solve the issue.
WICD does work under other circumstances, e.g. wireless connection. (But at home I don't have wireless, but just the modem and ethernet.)
Same wired connection ethernet connection works flawlessly on laptop running Windows XP SP2.
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

I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.

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");

I recently installed ubuntu on my mom's computer but I can't get the mouse to move trough the touch pad and I suspect the USB is not working either, because I can't get anything to work trough the USB, and the Internet is not working trough the cable, and I think wireless as well.

I have router and wireless card Linksys. Driver are installed correctly for wireless card.
Using WifiRadar I can see the access point is detected.
DHCP woks perfectly for wired lan.
However when I try to connect to the detected access point the ip addres is never retrieved and the connection never established.
I tried most of he basic instructions posted on ubuntu forums, but the problem doesn't seem to be with basic configuration: driver, essid, wep key, etc..
The problem seems to be with DHCP not able to retrieve an IP address from the DHCP server of the router. Of course the router works file with other laptops (windows based) that have wireless card.
I also tried the Network Connections setup part of ubuntu. That one shows the access point by its essid name in the list of wireless network, but when I try to connect it takes sometime and eventually asks for the wep key, which I provide and then it times out and keep asking it. The same wep key works for other pcs.
Can't figure it out. I am using ubuntu 9.10.
Some more details are the following:
1) Here the output from the log file: /var/log/wifi-radar.log
Of course it is set ... and dhcp client works for wired lan anyway.
2) diego@mysuperlaptop:/var/run$ sudo iwlist wlan0 scan [sudo] password for diego:
I tried everything I could think about in the UI windows setting (WifiRadar and Wireless Network Connections) a well in the config files from the shell. I just don't get what the deal is. I am pretty sure it is a DHCP issue but can't figure out what.
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.

The thing is, my wireless is working perfectly in windows. However, I can't get it to work in Ubuntu. It detects my internet, but refuses to connect.

All I know is that it seems that my wireless linksys network card is a WUSB600N Anyone that has any commands they want me to put in my terminal I can tell you but from other forums I try to put many in and get no output simply because I believe I do not have the drivers but do not fully know how to even install these drivers in the terminal or am not doing something right.
just now installed Ubuntu 10.10 on my Lenovo Thinkpad X41 it did connect to the wireless internet at the time of installation but failed to connect after the installation was complete and i restarted the computer.

View 9 Replies View Relatedmy wireless will simply stop working after each new webpage loads. Whats strange is that it will not disconnect me, and the wireless icon in the top right will continue to show that I am connected to the internet. I am currently tethered to my phone and the internet is working fine. Once If I switch to my regular wireless internet and disonnect and reconnect to my home router then the webpage will load fine only once then after that it will not work again until I disconncet and reconnect again.
This is not a problem for anyone else in my house who all use macs (needless to say they are all very smug about this). Also when I connect to my schools wireless internet there is not a problem. Also restarting my modem and router at home does nothing to solve the problem. Like I said before this just started up about 3 days ago and has baffled me since.
