Ubuntu Networking :: Wireless Connection Cannot Obtain IP With DHCP
Feb 16, 2010
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 have a home WiFi network that has been working fine for ages, which currently supports two Windows-based laptops and a WM5 smartphone. They all connect to the WiFi router (Linksys WRT54G) which in turn connects to the ADSL modem (Huawei MT882). The router is configured with a WEP key, the SSID is not being broadcast, and all MAC addresses must be whitelisted. I try to follow good wireless network security practice. I also have NAT running between the router and the modem.
Everything is working fine for the Windows clients, and now I am trying to add my Linux box to the mix. I am setting up an older HP Pavilion 510a desktop with Ubuntu v8.04LTS, using a Realtek RTL8185 WLAN card. The machine has an onboard RTL8139 LAN adaptor also, which works fine when I plug it in directly to an ethernet port on the wireless router. The WLAN, however, does not seem to be getting a DHCP packet, and keeps on autoconfiguring with a 169.254.x.x address. When I try giving it a static IP address it doesn't connect either.
As you can see from the screenshots below, the WLAN is working fine. I have it installed using the ndiswrapper and Windows drivers. I've been through the Comprehensive ndiswrapper troubleshooting guide but that did not resolve my problem.
I configured the network myself, and it works perfectly for my Windows machines. It is just my lack of experience with Linux which is preventing me from getting the wireless to work under Linux. I can get a HDCP packet in Linux when I am connected to the LAN using the RTL8139 adaptor, but not on the WLAN using the RTL8185 adaptor.
I installed PCLOS 2010.07 into my laptop and dual booting with windows vista. Now I got a weird problem that is when I connected linux to my wifi router, it cannot obtain IP! (it still work correctly in windows, problem just with linux) I had to manually set ip and that worked. Now i wonder what is happening, because I didn't see this problem with PCLOS 2009 borrowed from my friend few months ago.
I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.
Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?
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 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 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'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...
I did search, but could not find a solution.Right I've installed Ubuntu Server 10.10 on an old machine, installed fine and the system is running. I have a windows 7 desktop that is connected to the internet via wireless. The desktop then has an ethernet connection which is shared to the ubuntu server. The network looks like this.
Modem > Router > Desktop > Switch > Ubuntu Server My problem here is that there appears to be no connection from the server to the desktop. The server cannot connect to the internet.
When i ifconfig the ubuntu machine shows.eth0 link encap:Ethernetinet address: 192.168.137.2 Bcast:192.168.137.255 Mask 255.255.255.0 However on the windows desktop (the machine sharing the internet) these are the details for the connection to ubuntu server.ip 169.254.170.50 mask 255.255.255.0
is this a dhcp problem? is my server configured wrong?
I'm having some problems bringing up my wireless card at boot time on my Red Hat Linux 9.0 box. After some investigation with the boot scripts, I noticed that it was having problems with the DHCP negotiations when the ifup wlan0 command is issued.I then tested the command outside of the booting process and everytime the command is issued the first time, the dhclient fails to get any DHCP offers and returns with the message Unable to obtain a lease on first try. Exiting. and then exits.
If I then issue the same ifup command again a second time, it successfully receives a DHCP offer from the router and receives the needed IP address, and after this, the Internet connection on the box works fine. It is consistently doing this everytime. Why is it failing to obtain a lease the first time?
I had my laptop at work for a few days and when I brought it home I couldn't open up web pages any more. I have a DHCP connection (shaw cable).When I plug the chord from the modem into my windows machine I can open up web pages. When I plug it into my ubuntu laptop I can't open up web pages.
I have tried unplugging the modem and restaring my computer.I think that there is some sort of connection because when I open up Network tools it shows that I am continually receiving packets. As soon as I unplug the ethernet wire I stop receiving packets. For some reason I just can't open web pages.I also tryed typing 'sudo ifconfig' and 'sudo dhclient' in a terminal. I don't fully understand what this means but I saw it in another forum.
I've been connecting to the Internet via Ubuntu 8.10 on my Toshiba laptop fine for ages now, but today it has stopped working. Yesterday an update came through relating to DHCP and, like all other updates, I installed it. And now my laptop can see the wireless router but it cannot connect to the Internet. (As I always install the recommended Ubuntu updates I didn't look closely at exactly what the update said, but I did see DHCP in the title, so this is why I suspect my connection is now broken.) Or can anyone tell me how to undo yesterday's update? I really wish now that Ubuntu had a utility similar to Windows System Restore.
I have a similar problem. My ubuntu box is set up as a dhcp router for my Xbox360, my xbox can get ip and DNS information from the computer, but it doesn't seem to get the right info. The ip address it gets assigned is out of the range I've set in etc/dhcp3/dhcpd.conf.
I have tested several Linux Distros over the last weeks, and with all of them my DSL connection have been working out of the box (for intance Mandriva, Ubuntu, Mint). But it does not work on Dreamlinux, neither on Live CD or now where Dreamlinux is installed on my harddisk.
According to the guidelines provided by my Internet provider I need to use TCP/IP and activate DHCP. And make sure that PPPoE is not activated.
I see nowhere I can do this in Dreamlinux. In the controle panel i can run Wicd. Then I can chose to de-activate Wicd - this gives me an option of entering Adress, Networking mask, Gatway and Nameserver - for static ip it says - and this is the opposit of DHCP, right??
SO - what to do? Should I get a debian package or something? (Dreamlinux is using debian packages, as far as I could see)
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.
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
I'm still fairly new to Linux so please forgive me if my description of my problem leaves out important information. My problem is centered around using a AT91SAM9G45 development board (DB)on Fedora 10. I have directions on how to setup on my host machine a DHCP server to connect to the development board. I have installed an additional network card (eth1) that will be used exclusively to communicate with my DB.
The DB has been setup with an ethaddr=12:34:56:78:9a:bc and an ipaddr=192.168.251.191.
The following is info from ifconfig for eth1: eth1 Link encap:Ethernet HWaddr 00:0A:5E:1A:46:1C inet addr:192.168.251.190 Bcast:192.168.251.255 Mask:255.255.255.0 inet6 addr: fe80::20a:5eff:fe1a:461c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:38 errors:0 dropped:0 overruns:0 frame:0
How do I tell the shared connection that it has a static IP and that I dont want a DHCP on the network?Do I have to set up DHCP on the box with the shared connection, even if that box only runs DHCP for a single IP address being the eth0 that is shared?Or can I tell the shared connection that it has a static IP and still allow network manager to run the shared connection?Or should I specify static IP's for all clients and the shared network manager and install say firestarter on the gateway to run the NAT for the eth0 out to eth1.
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)
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.
Running 2.6.29-gentoo-r1 on a Sun Ultrasparc 10 with a Sun Happy Meal on eth0 connected directly to my cable modem. Intermittently, with a frequency between a few hours and a few days, I lose internet connectivity. Running ifconfig eth0 indicates all is well and I have a valid IP address but I cannot even ping the cable modem's management address; pings to 127.0.0.1 and eth0's IP address do get a reply but no other address I've tried does. I can 'fix' the problem by issuing
If I check the CM logs, it appears that it has rebooted itself prior to the loss of connectivity. The strange thing is that the incoming traffic doesn't seem to be affected by this, my PSAD log is full of incoming scans even during the periods when I can't connect to the net. I suspect this is an ISP problem (they own the CM);
