Networking :: Debian Wireless - DHCP At Startup - Can't Connect Once In Gnome
Apr 14, 2010
I am trying to get my intel pro wireless 3945abg working on this Lenny installation. My progress is as follows:
No wireless & LED (on the physical switch) won't turn on
installed NdisWrapper and netw5x32 driver
installed package "firmware-iwlwifi_0.14+lenny2_all.deb"
[code]....
Still no wireless, but when DHCPDISCOVER runs at startup, it is apparently assigned an IP address using wlan0. This only happens when the cable (eth0) isn't plugged in (eth0 is set to static) which leads me to believe that the wireless really does work for DHCPDISCOVER.
What I want to know so that I can mess about with it more is how do I switch between drivers? What I have been doing here is
This one has been bugging me for some time now. The network interface (as defined in Debian's /etc/network/interfaces file) fails to obtain an IP address from myuter. However dhclient br0 does.I'm using br0 since I run a XP virtual machine.network/interface changes are from a Debian howto on setting up the tap interface.As near as I can tell, the /etc/init.d/networking script basically calls /sbin/ifup -a. ifup is a binary.My /etc/network/interfaces file is:
My wireless in fresh Squeeze install would not connect automatically. I have to click on the network manager and enter the root password to connect every time I start up. I have "Enable Networking" and "Enable Wireless" checked in the Network Manager.
There are only 2 lines now in /etc/network/interfacesauto loiface lo inet loopbackWhat should I do to get the NM to look for and connect wireless automatically at start up
I am running 9.10 on my compaq laptop. I tried linux a couple years ago and was not impressed with it's operation on this machine (wifi didn't work, pain in the butt to make it work) but I just installed 9.10 and to my surprise, everything on this machine seems to work now automatically!
One minor annoyance though, when I boot my machine and the gnome desktop loads, it takes about 1 minute until the wireless finds and connects to my router. Granted, my SSID is set to not broadcast but I set ubuntu to find it as a hidden network and it does in fact work, just takes more time than usual to find and connect. Normally with windows, when it loaded, my wifi was present and connected immediately.
I use network-manager-gnome to connect to my wireless networks, but I can only use it with a graphical environment, and it doesn't even work that well since it will drop the connection after a few minutes and I have to reconnect it manually, that means I cannot leave my computer downloading a big file all night since it will only download for a few minutes, does anyone know what package can I use to connect to my wireless without the need of network-manager, even if it's through command line?
After searching/googling for information related to the topic, I haven't been able to get this working in KDE. Background: I have a Dell Studio 1745 with builtin Intel 5100bg wireless card. It connects to my Linksys WRT54G router just fine in openSUSE 11.2 & 11.3 using either KDE or Gnome. In Fedora 13 it only connects under Gnome, not KDE. Those are using NetworkManager. Using traditional ifup only works in Fedora under Gnome, i.e. nothing works under KDE in Fedora.
I've been using Debian Squeeze for a few years now, no troubles connecting to a DHCP server in PPOE session... (DSL service) until this morning (11.29.10) when now I do (that is to say; browser, email prog., terminal, real player, etc., just won't connect). I can do dual boot, & so am in Windows XP at the moment.
I just installed ubuntu for the first time, and I am not very familiar with everything yet but i am trying to connect to my university's wireless network and can't seem to figure it out. These are the directions they provide for linux users:
Use linuxconf Start linuxconf, go to Basic Host Information under Networking and Client Tasks. Click Adapter 1, and select DHCP. Click OK and Apply Changes. Finally, reboot
I tried running linuxconf from the terminal but no such command exists, is there a similar one for ubuntu?
I just reinstalled OpenSUSE 11.3 GENOME on my computer (Compaq Armada E500 w/512 MB RAM, 30GB HD, and Linksys WPG54v2 wireless card). After futzing around for several hours on two different evenings, I got it working all by myself! The only thing is,ow I have to manually connect to my wireless network every time,which gives me a a great sense of accomplishment. I start the computermber having to edit a script somewhere to make it connect automatically on system startup, but I can't remember what it is I'm supposed to edit or how I'm supposed to edit it
I using ubuntu 9.04. It was connected to the network with the manual IP Settings. Now the server settings have changed and we are supposed to move to Auto Assign IP (DHCP). All the windows machines are working fine, those are connected to network and using internet. But the ubuntu machine is not getting connected. Is there any any additional setting required for DHCP?
I am trying to connect to a WEP encrypted WLAN without using the DHCP server of the AP. (=giving myself a static IP)
So far i have tried:
Code:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?
My ISP finished some 'upgrades' on its infrastructure. The result is that I am having great difficulty in connecting to the internet.
I have 3 operating systems on my box - XP, Fedora 8 and Feota 12.
I connect using an ethernet card, using dhcp. In fedora 12, the ethernet card is controlled be networkmanager. After the ISP completed their upgrades, I was not able to connect. I tried to connect manually using
Code:
There was an error message -
Code:
I read the advice here: [url], and removed all but the important lines.
But even after that neither ifup eth0 or dhclient eth0 works.
In fedora 8, the ethernet card is activated by ifup eth0 in /etc/rc.local. I was able to connect on a couple of occasions, but that too stopped working. I tried both ifup eth0, dhclient eth0, and tried to use the gui( which fires the dhclient command), but none worked.
When I use windows, it takes about 2 minutes to get an ip (earlier it was immediate). Sometimes that doesnt work and I have to click on "repair" whereupon it starts working.
I have a home network, with an OpenWrt router operating successfully as DHCP server (using DNSMasq). I'm planning to install LinuxMCE on my main fileserver and in order for this to properly detect devices around the home it requires that it is the DHCP server. That would be fine except that I sometimes power down the fileserver (eg. when my in-laws sleep in the spare room where the server lives) and that would leave me with no DHCP which creates problems (when my in-laws want to get their laptop connected to the internet).
One answer is to get new in-laws which would be OK except that I'm still pretty keen on my wife. Alternatively is there any way to set up a fallback DHCP server ie. the router would check if there's a functioning DHCP server on the network (ie. the fileserver) and if it gets no response it will serve DHCP addresses itself.
I have a home Debian server running, and i would like to set it up as a gateway. I have 2 networkcards in it. So internet comes from the modem and on the other card i want to setup a dhcp server and it has to share the internet. But i want it also to connect to a vpn and share the internet of the vpn.. Is that possible?
For changing the the mac address of my lan card( eth0) in linux fedora 9(solphur) i used this command
And i could change my mac address successfully but now i couldn't connect to my network via a dhcp server ( in configuration section of my router im going to check my new mac address (because i want to spoof) ,how i can do that?
Since that time I moved to Archlinux and I love it. I do however run lubuntu live from a USB for my work PC. I am having a problem with it. I think it's okay to post here because the core of the system is still Ubuntu. I don't think LXDE is the problem. I start up the live environment and it says 'wired connection connected' but I can not load any pages or do anything.
I thought it may be a problem with configuration so I copied down (from Windows) the IP, Subnet, Gateway and DNS. I put them in manually and it doesn't say connected any more and still no connection at all. I am unsure what to do from here. I am not really familiar with Ubuntu enough to try much. I tried to 'dhcpcd eth0' but dhcpcd isn't installed. I guess the default Ubuntu network manager has dhcp enabled automatically.
I've only been using linux for a few days so I don't know all the tricks. I'm pretty savy configuring windows networks however.My adapter is (according to windows) a: CNet PRO200WL PCI fast ethernet adapterLinux says it is a: 21x4x DEC-tulip compatible 10/100 EthernetI do seem to be getting an ip address from the DHCP router, but I cannout ping any other ips or connect to the internet.I've tried a bunch of different options, switching things back and forth, but it still doesn't work, and honestly i don't even know what some of the options mean.
ALSO, if this helps: paladin:~ # ifconfig eth0 Eth0 Link encap:Ethernet HWaddr 00:08:A1:03:3C:99
I have an ubuntu 11,04 samba domain server, I want to also configure this machine to work as a dhcp server, however this have give me some issues with te windows 7 workstations, my guest is that it have something to do with the iptables because those station do join the samba domain went both server and workstation are conected to a router.
This is the script I use at boot
Code:
#FOR SHARED INTERNET /sbin/iptables -P FORWARD ACCEPT /sbin/iptables --table nat -A POSTROUTING -o eth2 -j MASQUERADE
[code]....
I haven't test it with windows xp station but I have use the same code in the past with no problems, and since this is my first time joining windows 7 station i belive there must be some other port that need fowarding.
Alright, I'm running Ubuntu KK 9.10 and I've probably read every ICS tutorial on ubuntuforums. I'm running wireless internet via a Linksys router and have a LAN card in my system as well.
(lshw -c network)
Code:
I tried the easy route with 9.10 (setting my wireless to DHCP and LAN to share connection) and although Ubuntu recognizes the Xbox when its turned on (I get a nice notification saying my wired connection is active) the Xbox gets no internet, and doesn't even recognize the connection. (when I tested the connection it failed before it even hit network...)
I had the wrong WPA password.[/blush] It appeared to me that it was connected OK at the physical/datalink level but apparently that was not the case.I've set up an old PC with the latest Ubuntu desktop and am trying to set up wireless networking with a TP-Link TL-WN722N. It only came with Windows drivers but from a thread elsewhere I got it to where it finds my router and connects with the password. However, it doesn't pick up its IP details. The router is working fine wirelessly on my phone and wirefully on my other PC.
I've edited /etc/network/interfaces with "auto wlan0" and "iface wlan0 inet dhcp" but after restart the wlan0 interface has no IP details. Originally the interface had IPv6 details but I cleared that with ifconfig. Under the Network Connections Wireless tab it has "Auto" followed by the name of my wireless connection so it appears to have connected OK. Now when I click Edit for that connection nmame, the IPv6 tab says Ignore and IPv4 says Automatic (DHCP) but Addresses is greyed out and the other fields are all empty.
I am trying to configure an external wireless bridge for a few systems to replace a very long, duct taped cable.
I have it set up and it is connecting, at least I can see the pfsense router on the other side and ping any machine in the network.
Here's the issue, I cannot get dhcp to work across the link. I set a static address (dns servers and all) but when I try to ping google i get "Network is Unreachable"
I have a WET54g bridge that I am trying to get connected to a wireless network that only allows DHCP. The idea behind it is that I would like to connect the Cat6 out of the bridge to a switch allowing multiple wired computers to connect to the wireless network. The bridge will easily connect to the network once I put the WEP key in, however, there is a kink after that. When I connect the Cat6 to my computer and request an IP for that computer, it self assigns. This tells me that it is not talking to the wireless network through the bridge.
I can not find which IP address the bridge was assigned so that I can talk to it. The sub net is 255.255.240.0 which leaves quite a few possibilities. I know that the bridge is, however talking to the wireless network because the light is steady on the front of it which indicates just that. One other thing to stack on is that I know that there is a "splash page" which comes up when any computer connects. You click on the agreement and then you are allowed onto the network. How can I get my computer to talk through the bridge to the wireless network?
I'm setting up my first home server. I'm running Debian Squeeze and I can't get my machine to connect to the internet on boot.The only way I've been able to is by logging in and running the following commands in exactly this order:
Code:
sudo dhclient sudo ifdown wlan1 sudo ifup wlan1
My /etc/network/interfaces looks like this
Code:
auto lo iface lo inet loopback auto wlan1
[code]...
I should clarify that by not able to connect I mean that I see the DHCP discover attempts but it fails after a few attempts and says "no DHCPOFFERS recieved" So I tried putting the above commands into a script and invoking that script in /etc/init.d/rc.local and I can see that it runs but I have the same problem. I need to be able to reboot my machine as I'll be administering it remotely.
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.
After an error occurred i can log in using the recovery console and startx manually.
If i understood correctly recovery mode uses /etc/rcS.d which starts the computer with minimal services and the normal startup is /etc/rc2.d. What can rc3, rc4 and rc5 be used for? Can anyone run different desktops (gnome, xfce, etc) using these runlevels (i am considering that the base system install is the same for all desktops)? Where i can find information about the services that are listed in the rc folders, since some (hibernate, bluetooth, apache2) are not useful to me at the moment.
I am also interested to find out what makes the computer start at it's default runlevel. Is there a way to start rc2 (or rc3, etc) from the recovery mode? When i used to start my computer, it would load into grub, and then it used to get me to the login screen. This is something i would like to avoid (the login screen), and start at the command prompt. My startups are minimal since the computer is always on. I was thinking of 'copying' rcS into rc2 for a normal console start and then start rc3 or rc4 or rc5 to load a desktop.
I have installed Fedora 10 on my A860 Dell Vostrol Laptop with AR242X Atheros Wireless card. Wireless card worked out of the box and i could detect wireless network and connect to it. But i have a problem that, my wireless connection is not able to get IP address from the DHCP server. Please help me out what can i do to get this working. I am using WEP security and authentication is open system.
I have windows 7 beta installed on the same machine and on that wireless network works fine so i am sure that there is no problem with the wirless network. I am using DIR-300 router from D-LINK. I tried to see packet log on wireshark and there i see that there is no reply to the DHCP discover message. Actually i don't see any RX packets at all. Which is not normal as there is traffic on the network.
