Ubuntu Networking :: No Automatic WiFi IP Address - Cannot Use Bluetooth Services
Aug 12, 2010
I have two problem with my wireless card:
- When I connect myself to a wireless network I must give the dhclient command, to obtain a local ip address
- The system say me that haven't a bluetooth adapter, and so I can't use bluetooh services (I've try by graphical interface and by console)
These problems began when I've passed to ubuntu 10.04!
My Wireless card is: Intel Corporation Wireless WiFi Link 5100
Suddenly after a long time with fedora (now with fedora 15), bluetooth and wifi not working on my laptop (now I'm connected to cable), I checked the network in console doing this:#systemctl status network.serviceAnd response:network.service - LSB: Bring up/down networkingLoaded: loaded (/etc/rc.d/init.d/network)Active: failed since Sat, 03 Sep 2011 21:18:24 +0200; 1min 50s agoProcess: 2949 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)CGroup: name=systemd:/system/network.serviceInstead I do the same query with the bluetooth service and gives me all OK, but does not work, I do not
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?
I'm using a Hama Voiis bluetooth audio device connected to my stereo. Both my girlfriend (running 9.10) and me (10.4) can pair with, connect to and stream audio from whatever application we use to the device. However to do so requires a couple of manual steps which I'd like to optimise.
First it's necessary to manually connect to device, since we both want to stream to this, connecting manually seems the best since I suppose only one can connect at any one time. Once connected it's necessary to select "Output" in "Sound Preferences" in order to use the keyboard or multimedia keys to change the volume. This latter step is a little annoying since it has to be done every time we connect. Does anyone have a solution that automatically makes this change when connecting?
My LAN internet will not work on my ubuntu computer. I have been told that its because ubuntu downloaded an update that changed my IP adddress from automatic to static. how to change it back and prevent it from happening again?
i have a bluetooth modem (BlueSMiRF) that is connected to Arduino Duemilanove. I am trying to see serial communication messages from the bluetooth modem.
I have Blueman Device Manager that enabled SPP (Serial Port) and it says :
Code: Serial port connected to /dev/rfcomm0 How do I see the serial communication on this?
I tried on console
Code: $rfcomm listen 0 but it's stuck at Code: Waiting for connection on Channel 1 Is there any other way to listen (and also send) to serial comm msgs on bluetooth?
When i connect to my laptop a bluetooth usb stick, the bluetooth could not be turned on. the bluetooth dameon is on, and when i press the turn on button, nothing happens. in windows the stick works fine.
The bluetooth manager does not detect a bluetooth dongle .trying to use ndiswrapper to fix.I installed device manager and the results are shown below.i downloaded the windows driver suite. It has 4 .exe self extracting driver archives and a setupconfig.ini. The .ini file is below.I was able to extract one of the 32bit archives on a windows machine and it had about 8 .inf files that are titled weird and would not install properly using ndiswrapper probably because im using the 64-bit architecture. there are 2 64bit .exe's in the driver download, but how can i extract them in ubuntu and do i really need to install all 8 .inf files. also do i actually need to make a .inf file? if so how?

I have broadcom wireless card in my system. I got the driver from broadcom site. I compiled it against my kernel and the module works fine. How could I automatically load this driver at startup. I followed the instruction found in the driver source README file. But its not working. The steps I followed are as follows:
The same steps I followd in 2.6.26 kernel and it worked fine. Now its not working in my new kernel 2.6.32.For manually loading it I have to remove the ssb driver and the download this one. Otherwise it will not work. So I tried adding ssb to /etc/modprobe.d/blacklistle. But that driver loads during startup. So each time I have to manually unload the ssb driver and insert the new one.
When the audio output of my laptop (running ubuntu 10.04 LTS) is configured to play via bluetooth to my bluetooth receiver (like a headset, a Belken H15 A2DP audio stream), my wifi connection is severely degraded (..... keeps pausing to buffer data).Then when I switch the audio output from the bluetooth device to the soundcard (without disconnecting the bluetooth device), you can see ..... suddenly start buffering and working fine again until I switch back to the bluetooth receiver.Other bluetooth devices (like my Droid) connect to the receiver just fine, but not this laptop.
If I understand correctly Ubuntu does not allow a wifi connection until a user loges in. That makes it so that prey (see preyproject.com) cannot send notices until someone has logged onto Ubuntu.what I would like to do (but I have no clue how) is to set up a user account that automatically, in the background, logs on at start up. Then this little user login would establish any Internet connection that is possible (wifi or lan) and start the program 'prey'. This should all be totally transparent to the user that would just see the regular log in screen.
I purchased 2 CSR V4.0 dongles which work fine, one in Deb8 and one in a Win7 laptop. The only problem is they both have the same mac address so my Samsung Tabs get confused. I have thoroughly researched how to change these but most of the suggestions want a dev reference such as wlano or eth0 which USB dongles do not have a dev id.
The only alternative is to use bdaddr which comes with the bluez package but it must be compiled with the --enable-tools option.
When I try to compile I get the error "error:D-Bus library is required". When I check the config.log it suggests:
"Package dbus-1 was not found in the pkg-config search path. Perhaps you should add the directory containing `dbus-1.pc' to the PKG_CONFIG_PATH environment variable".
Dbus is installed on my system but I could not find dbus-1.pc. The only reference was the directory "/usr/share/dbus-1" so I added it to my $PATH variable. This did work.
I recently installed the Rhythmweb plugin. I can go to http://localhost:8000 on my own machine and control it that way, so I know that functions properly. My issue is my phone finding the correct path. I have it bluetooth synced, with the laptop device's name being "peter-laptop" (I reset it to the default just for clarity's sake), and my laptop and phone are both on the same wifi network as well.
I have tried many variants of peter-laptop.local:8000 and peter-laptop:8000 but no luck, in opera or the default blackberry browser.
Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.
So I want to get mount/umount option under right click services menu. I went to Dolphin -> Settings -> Configure Dolphin -> Services -> Download New Services and from there I installed KDE CDEmu Emulator and MountISO. But neither of them is showing up in actual context menu. Neither in Dolphin -> Settings -> Configure Dolphin -> Services for that matter. I tried to install them as normal user and as a root. I went to have a peak in /usr/share/kde4/services/ServiceMenus/ but they aren't there as well... It's just me or lots of things seems to be not quite working in 11.3?
I upgraded my laptop from Debian Wheezy to Jessie the other day, and just as before my wifi auto-connects to my router, and I can "ping http://www.google.com" just fine, but only for like a minute. Then the Internet access dies, but I'm still connected fine to my router, and I can ping its IP address. If I connect to the router through cable / eth0 everything works just fine, and I have full Internet access.
I assume there is something wonky with how ip address is assigned after the upgrade, how can I fix this, or trouble shoot further?
I am working on implementing a protocol on NS2.34 .I really need help to solve this problem . Actually , I don't now whether the problem is generated by the tcl code or the c++ code when I run the simulation, I get this result :

My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.
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 am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.
