Ubuntu Networking :: 11.04 No Wirless Connection With LiveCD?
Apr 30, 2011
For upgrade-check I used today Ubuntu 11.04 X64 LiveCD om my Sony Viao VPCF13Z1E Laptop to check if all my hardware can be used with Ubuntu 11.04. When Ubuntu 11.04 X64 LiveCD was started I could connect to my network with my wireless network adapter. But when I tried to browse with Firefox I could not get a connection. A ping to my router or to an other machine did neither work. To browse the internet with Firefox and a wired connection works normally. When I use Ubuntu 10.10 X64 on my laptop the wirelss connection works normally.
The command lspci | grep -ni network on my Sony laptop responds with: 23:02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) I use a wireless connection based on wpa/wpa2
Connection information from Ubuntu 10.10 X64:
Interface 802.11 WiFi (wlan0)
Driver iwlagn
Does anyone have an idea how to solve this problem? Or do I have to report a bug?
Ever since my BT Hub 2 has updated a few weeks ago I'm unable to connect to the internet either wireless or wired. I duel boot on my netbook with xp and duel boot my desktop PC with windows 7. None of the Ubuntu�s are able to connect, I have no problems with the windows side of things.
Has anyone any ideas on how to fix this until BT decide to fix the problem. Preferably a step to step guide as I have limited experience with Ubuntu. I�m using Ubuntu 11.04.
am finding it very hard to get a wireless connection working, I am using openSUSE 10.3 (i586)and I have a Edimax EW-7711UTn USB adaptor, I have tried to follow the instructions on this forum and I think I have set it up using YaST2 but I still can not connect to the internet.
i'm really frustrated with ubuntu the last little while. i thought things would be better but its hard to stay optimistic when nothing works. My wife's laptop an MSI A6000-029US has an nVidia chipset [MCP79 (rev b1) according to lspci in lucid].i expected the RaLink RT3090 not to work out of box.. but the Ethernet controller for the wired connection doesn't work either.i can't get this thing online to update it. the syslog says:
Code: Apr 30 04:13:39 msilappy NetworkManager: <info> (eth0): carrier now ON (device state 2) Apr 30 04:13:39 msilappy NetworkManager: <info> (eth0): device state change: 2 -> 3 (reason 40) Apr 30 04:13:39 msilappy kernel: [ 402.001626] eth0: link up.
I am running Ubuntu 10.10 Netbook Remix on a Toshiba Netbook NB300. After performing an upgrade I find myself unable to connect to my wirless network and have lost the wifi icon in the task bar. Ethernet connectivity is however working.
iwconfig shows: wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off ifconfig shows

I need to take to bring back wireless connectivity to my netbook and restore the wifi icon to the task bar.
I was trying to use my other computer that has Windows XP, and was running it on the LiveCDI could not get on the internet! I had no wireless connections, when my laptop (Running Ubuntu already) can pick up the signals. I tried to put in my WEP, MAC, and my SSID and I could still not get it to work. No internet connections when I press the "Triangle Internet button at the top". What Am I doing wrong? I am using a Zyxel G-720 v3 wireless adapter to connect (worked fine with Windows XP).
I've read that you can connect to the internet after booting from a Linux LiveCD. How does this work? For example, if you use dialup, and modem+connection sw are configured, you just connect as usual? I'm conceptually fuzzy on this--since the sw for dialup lives on the hard drive, you can access the hard drive as usual? And if you have doc or text files on a USB flash drive, you can access the flash drive and open+edit the docs using a text editor included on the LiveCD?
I'm looking for a bootable (livecd) cd that will perform an antivirus scan on a computer without needing an internet connection. It should have its latest virus signatures included so I can simply download and burn it. I've seen [URL].. suggested in various questions asked here, but that post is from 2008.
I tried:
Bitdefender rescue cd Trinity rescue kit (TRK) Panda SafeCD
i have ubuntu 11.04 ihave tried mpvick@ubuntu:~$ sudo apt-get install b43-fwcutter && sudo apt-get install firmware-b43-lpphy- but it didnt work i am using a direct connection but it said it could not find b43 also i am dual booting between windows 7 starter and ubuntu 11.04 and this is my firtst time using linux also i am in 9th grade so i probably need it in walk through format i have a brodcom 208.11 card and im running it on the hp mini 110 and i downloaded strait from ubuntu.com so no disc or usb any way like i said the wirless says that i am missing firmware
I have just installed ubuntu from the ubuntu website for my laptop. Its great. Whatever i read or do though i cannot connect wirless to my bt home hub.
Ive been having some troubles with wireless. Ethernet works but wirless (at first) doesn't work. However, when i plug the ethernet in, all the wireless networks it detects are populated and i can then connect until i shutdown my computer.My disable internet button on my computer also doesn't seem to work well. It is always blue, and when i press it and have internet connection estabsliehd, it erratically turns from blue to orange to blue and then stays on blue.
When i have shutdown and booted up and i haven't placed ethernet in (so wireless doesn't work) it wont even change color.Any solutions? I dont know what info to include so just let me know and when the wireless does it work, it is slow in opening a new tab and connecting to google.
Have an issue with my wireless.It sometimes doesn't connect to my wireless. And sometimes when it does it gives me an invalid IP address.I have a lenovo SL400 Laptop.Intel 802.11agn wireless is my adaptor. And I have OpenSuse 11.4 with gnome. I works fine if I give it a static IP Address but that will create an issue with other computers on the network.Is my desktop environment (GNOME) or is my Wireless adpator not compatible with opensuse.
When I try to connect to the internet wirelessly with Fedora 14 it tells that the wirless firmware is missing. Is there anywayI can fix this or find the firmware for a Dell Wireless 1379 Wlan mini-chip? The Chipset is BCM4315Also my computer is a Dell Inspiron 1545
I am appealing to the minds far greater than mine.. I have been using this forum with resounding success without having to post for some time, and I am more than impressed with what you can resolve by simply trawling through the archives, on this occasion however, I'm stumped.
I have a desktop upstairs in my home running 10.10, I have a Ralink Wirless LAN dongle RTL8188CUS with a mini CD with all the drivers etc. Now, when I physically install the dongle Ubuntu does not firstly even acknowledge it's existence, so, I unpack the CD Lynx dir and there seems to be no way to install it? I can't see a code to run in terminal to install.. nothing?
I am very new to this and tried searching for this problem in the forums but have not find anything. When I installed ubuntu (formatted HD), the installer gave an error but then seemed to proceed as normal and everything installed (from CD). However, when I boot up from Live CD all my wireless works fine (it detects networks, connects, etc.) When I boot up without the CD it says networking disabled and gives me no other options.
When I run Kubuntu on livecd everything works perfectly, I just click on systray icon, select my network, enter wpa pass and it's all setup! But after I installed Kubuntu on HDD it doesn't work like that anymore. [URL] Version 10.10. Maverick Meerkat
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
I've been using Linux for about 2 years now, mostly Ubuntu & derivatives, but I've also tried Fedora, Mandriva, and others. I wanted to give CentOS a try because I'm very interested in going for a Linux+ or similar certification, and so I'm looking to start learning how to configure & maintain Linux servers and so on. I have a friend who's a Linux sysadmin, and he recommended CentOS as a good learning tool.
Anyway, I've only got a wireless connection in my office at home (the actual cable modem is downstairs) so I intentionally chose a wireless adapter that would work with Linux -- it has a Realtek RLT8187 chip, for which there is support built into the kernel, or so I've read. It has worked out of the box in just about every distro I've tried, and indeed it worked OOTB when I tried out the CentOS 5.5 live CD.
However, when I actually installed the CentOS to my hard drive it no longer worked -- I have only a greyed out option for a wired connection (presumably since my motherboard has an ethernet adapter, but there is no connection). Why the wireless would work in the live session but not after install? Is there a firmware file or something I need to track down? I did look on this page, but it doesn't mention anything about RTL8187.
When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?
I have problem in making connection to my vpn server I can make connection from windows xp to that but can not open any website and I can not ping 172.16.10.1 when connection established.

I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
I connect to my work with GRDC through a VPN. All worked fine until yesterday. IT is now very slow. Could this have anything to do with the fact that Update Manager was only able to do a partial upgrade?
I use Ubuntu 9.10 I tried the RDC on a Win XP machine and the speed is normal, so I don't think the Remote Desktop Server is the problem. Is there a way to test thespeed of the VPN connection or the RDC connection?
