I have a laptop Acer aspire 5100. I installed Ubuntu a while ago and it was working well. Last week I updated it using Update manager and ever since I haven't been able to connect either wireless or wired connection.
I'm using Archlinux with NetworkManager to connect to the internet. When I'm in my room, I've an ethernet cable and still receive the wireless signal.Sometimes (like when we have a power cut, somebody is rebooting the router or simply something wrong with the provider), I'm disconnected during a few seconds, NetworkManager ask me again the password of the wireless (even if it remembers it), and then I'm ok.But when I'm not in front of my computer, while I haven't push the button "ok", it doesn't connect, even with the wired connection.That's not very normal in my opinion as there is supposed to have two different and independent connection. No ?
I intent to install an ssh server on my computer but if I cannot access it every time there is a problem that won't be very useful.
I have a wired problem in Ubuntu 10.10, My Ubuntu can connect with Wireless network, however it cannot connect to Wired Connection. I installed dual System, one is Ubuntu 10.10, the other one is Win7. Under Win7, I can both connect to the Internet in Wired or Wireless mode.
The more wired phenomenon is: When I plug in the cable, I can see the icon connected in my network manager. But I cannot visit any URLs. By checking the "ifconfig -a", I can see the IP addr was assigned to my eth0.
installed Ubuntu 10.04 on my Dell 1564. My cabled netwo connection is not working.buntu has been dual booted with Windows 7. Internet connection on Windows is working. I have an ADSL modem connected to my laptop via the cable.I have given the details of commands asked to be execute(viewed various posts).
Running a wired connection through a Linksys router that suddenly stopped working today.I thought this was a ipv6 issue sinced I enabled some of those settings to share a connection with my PS3.I have since disabled IPv6 in Firefox and through the grub. The RealTek adapter will not even show a connection through the network manager when connected.The onboard adapter will show a connection, give me a ip address and MAC but still will not load the internet. I've tried uninstalling and reinstalling both adapters through the network connections, as well as reinstalling Firefox to no avail.I've also tried using Open DNS servers.I cannot ping through the network tools either. Hard for me to paste a ifconfig since I'm on my laptop.I'm running Ubuntu 10.10 (not dual booting).I did some updates this morning but it worked fine for a little while after that, until I tried to connect to my PS3.
I recently installed 11.04 on my PC (was running 9.04), and beforehand "tried it out" and networking was fine. I could access the internet no problem.I then ran the install, and fully formatted my HDD (i have 1 HDD for the OS and another for storage)It crashed halfway thorough, so no problem, i just re-formatted the hardrive and installed.However, It didnt connect to the internet, I literally tried every single forum looking for the solution, including editing the Network interface file.After a bit of diggingfound my user privileges did not allow me to connect to ethernet, and randomly use audio devices.SO, no problem I checked the boxes, but it still wont connect to the ethernet now, and it was fine before, tried re-installing twice with full format, but still doesnt work.
After installing UNR onto my dell mini 9 and downloading the correct drivers to enable wireless internet (using this site: [URL]), I decided to load ubuntu onto my brothers netbook. After the installation completed, I went to do complete the steps listed in the above article, however I was unable to connect to the internet using an ethernet wire.
Ubuntu 9.10. Everything works fine until yesterday when I cannot connect to network. My lan card is Realtek PCI and is present on system (i can read mac address and all settings). In connection manager I was try to set everything manually (IP, netmask, gateway and DNS) or leave automatic - without success. I am connected to router. I don't want to feed "log-hungry" people because how to resolve ubuntu lan problem can help me (not someone who will want to try). I cannot connect manually because there is no option when I click on network icon (I can just uncheck connection, but that's all). I can't even access to my router (from computer with Ubuntu, because I can access from another computer). All logs shows lan card proper. Windows XP on the same computer booted from another HDD works fine.
I'm running 10.10 on a brand new computer, and up until this afternoon the wired connection was working fine. All of a sudden it stopped working (and doesn't work in Windows either).I ran sudo dhclient and it gave me:
DHCPDISCOVER on eht- to 255.255.255.255 port 67 interval 3 (7, 9, 10, 18, 13) No DHCPOFFERS RECEIVED No working leases in persistent database sleeping
I am using a livebox with two wired PCs. One windows and one Ubuntu. The Ubuntu machine used to work fine on the internet. I have not used it for some time,t having got it running again there is no wired connection - Ubuntu searches but comes upd connection disconnected. I have checked the cable and that is fine I swapped the two cables over and it works fine on the Windows machine.The cable in the livebox shows two constant lights. The green light does not flash though - it is constantly on - I beleive this means the connection is good but there is no data flow
My ubuntu karma desktop is plugged into a wired connection that goes through a router and into my cable modem.Everything was working fine like it had been foseveral months yesterday morningSomething happened by the end of the day that has screwed up my wired networking. I plugged my laptop into the same cable thats plugged into my ubuntu, and the cat5 cable is live. Also when I plug said cable into the ubuntu box, the ethernet lights come on, or atleast a solid green one. Meanwhile the network connections Icon continues to have a red X and a tooltip saying "No network connection".
Under network settings, there is only one wired network "Auto eth0", but it says "last used: never" which is strange since I've been using this for months. When I click edit the main settings are MTU automatic, ipv4 automatic DHCP, and ipv6 ignore.hat could the problem be? By chance did a karma update get released that broke the networking
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.
I have Ubuntu 9.10 installed on a VM Server 2.02 with a Win7 32 bit host. When the host is wired into my network, the Guest (Ubuntu) has internet conductivity. However when the host is connected via Wireless, the Guest Does not have any internet connectivity. The VM Network connection is set to Bridged.
I dualboot Win7 and Ubuntu 10.04 for quite a long time now with no problems.... but now wireless works perfect on Win7, but I can't even connect Ubuntu with a direct wired connection.... ubuntu connects to the actual Linksys Wireless router just fine, but just won't take the internet, and I've tried two different Wireless cards.this all started (I dunno if its relevant or not) when I put in a new TV tuner, which I obviously took out right away. But the problem is still there. I don't think its the card, I'm pretty sure its just some kind of setting that I've messed up or something because when I connect to the network its near 100%.
My brother installed Ubuntu 9.10 on a Packard Bell Easynote NJ65. He has a wired home connection, which seems not to be working now. It was working with the same machine under Vista. What are the first places I should look? Any hints or clues or people with similar issues would be most welcome.
Everything seems to be fine while she is connected via Wireless. When she plugs in the wired connection a problem occurs, it seems that every SSL Site and/or encrypted Website cannot be shown on her Notebook, for example shopping at Amazon.com. The Problem does not persist the whole time, sometimes it works for a few seconds and you are able to fill your cart.
Other Informations: The Connection has been tested with Windows 7 and with Ubuntu (USB-Live-Stick Lucid)... no difference.
Is it possible that her Hardware is not running correctly? What should we do next?
Tomorrow we want to reset the computer to factory default status.
Are there any possibilities of testing a SSL Connection using the Terminal?
I'm running Windows 7 and Xubuntu 10.10 on a dell pc. My wireless works fine when I run windows 7, but on Xubuntu, the wireless doesn't even come as an option. When I try to plug in the wired connection, it loads for about a minute then tells me I'm disconnect. The option for the wired connection is there, but when I try to click it, the same thing happens. What do I do?
I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...
I'm new to Ubuntu - I've decided to give Ubuntu Studio a go as an alternative to Windows. However, after installing it, neither of my network cards work. I have a Intel Pro Wireless 3945ABG wireless card, and a Broadcom Netlink Gigabit Wired card. Neither work, And I'm not sure how to. I've tried searching, and have come up with the .tgz file here, but I have no idea what to do with it I'm concentrating on the wireless card for the moment, seeing as that will be the main one I use.
I posted here a couple weeks ago about my wireless issues and someone suggested I download an update of firmware for my Broadcom wireless card. The problem is I can't even connect to the Internet with a wired/Auto Ethernet connection in order to download said firmware. I tried downloading it on a different computer then using a flash drive to transfer it, but when I opened it on my computer, a message popped up saying the files were corrupted (this happens every time I try to install any program/update from a flash drive). So I tried today to use the wired connection to download the firmware but a) it wouldn't recognize the connection, so I deleted the AutoEthernet connection, rebooted, and activated the new one, as per the solution I'd read in a different thread on the forums. The wired connection worked, but only intermittently--it disconnects about every minute or so--and even when I'm connected, Firefox won't load any pages so I still can't get the update I need for my card.
I feel like I'm out of options here--I've been having this problem for about 7 months and I, or my much more Linux-savvy acquaintance, have not been able to figure out the problem. I'm thinking the only solution at this point is to go back to running Windows, which I really don't want to have to do.
I just installed Ubuntu 10.04.1 on my Dell Inspiron 1545 laptop, but I can't connected to the Internet with a wired or wireless connection. I have a BT Home Hub 2 wireless router. I can connect to the Internet when running Windows Vista, but not with Ubuntu.
I tried installing the Broadcom STA driver off of the live disk, which initially seemed to work. However, I still couldn't connect to the Internet and when I clicked on System > Administration > Hardware Drivers, there weren't any proprietary drivers to install or that had been installed. Also, when I reboot, Ubuntu tries to connect to my network automatically but always fails. That's what makes me think that a driver has been installed, but just isn't the right one or isn't working.
I have been looking around the forums searching for similar problems, it seems not only me had this problem. About a month ago I did a regular update via Upd Manager. The next day - no wired connection.Still managable, since the local library has wireless. Now that won't work either.Just after I upgraded from Jaunty, I accidentally removed NetwMngr from the top right corner of the screen, but that should not have anything to do with how the program works, right? I now cannot reach NM, if I run it from the terminal, nothing happens visibly.
My wireless connection has been giving me some problems, so I decided to try a wired connection directly to the router. However, when I try to do that, it doesn't work. When I click the network manager icon, it says that the wired device is not managed.
ifconfig gives this:
Link encap:Ethernet HWaddr 00:13:d3:dd:12:79 inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::213:d3ff:fedd:1279/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I ran sudo dhclient to try release and renew my IP, in case that was the problem. It released and renewed successfully, but still didn't connect to the Internet.
I tried to install Ubuntu 10.10 with the live CD and it kept freezing at creating ext4 file system for /. I finally got it installed using the alternate cd method. Now, my internet connection is not working. I am connected to a router with DHCP. When I boot up with windows, everything works fine. Ubuntu says that I'm connected with a wired connection but I can't access anything on the internet.
I'm recent to Ubuntu and have just installed version 10.04 32bits desktop version along side my Windows XP.My wireless internet connection works perfectly under Windows XP as this thread can prove it, but it does not work on Ubuntu.When checking the connections on Ubuntu I see:Wireless Network - disconnected.
Recently installed Ubuntu 10.04 on HP Pavillion ze5400.Wireless card is bcm94306MP. Wireless connection shows as disconnected. I am troubleshooting using the Ubuntu documentation on solving wifi problems. Ran ishw and it appears I do not have a driver properly installed. Obtained what I believe is the driver: bcmwl5.inf and bcmwl5.sys. Installed bcmwl5.inf using ndisgtk. I know its there as I can see it in System>admin>windows wireless drivers. However lshw still does not show it under configuration. I understand I must put the sys file in the same folder as where this inf file got installed. I assume all I do is copy and paste it into that folder. Is this correct? Next I need to find that folder. I tried the command find /home -name bcmwl5.inf and it did not show up. Can someone educate me just how to do this, that is find the folder and insert the sys file?
After I pass this hurdle then I will tackle trying to configure the card.
I have a cisco linksys wireless adapter (WUSB600n) which, most of the time, great when booting up. But mostly after some time (1min- 1hr.) it disconnects. When checking the status I can see some of the networks around me, including mine. But selecting it doesn't do anything. I searched the forums and tried:
sudo dhclient and sudo /etc/init.d/networking restart
But still no connection; the only thing that helps is rebooting.
