Ubuntu Networking :: Wired Internet Not Working Since Update / Wless Not Working
Jun 21, 2010
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.
I recently did a fresh install of 10.04 from 9.04 and since then I am unable to use Internet. However my ethernet connection is working fine, as I am able to login to modem and check configuration. I reinstalled twice, downloaded fresh 64-bit & 32-bit and also followed kernel update steps as in few forum posts, but no joy. The firefox is throwing an error "The connection has timed out". My internet connection is working fine as I am able to use my Windows Laptop to post this message. I checked system > administration > hardware drivers and couldn't find any unsupported hardwares.I had similar issue when upgrading to 9.10, hence stayed on 9.04. When I looked at LTS image, I couldn't resist and cleaned up 9.04.
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.
I installed Ubuntu 10.04 into my compaq notebook. The problem is that I am not able to connect to my wired broadband internet.
Here are the details of my attempts so far: 1)"ifconfig -a" gave 2 devices eth0 and wlan0. 2)"pppoeconf" was unable to detect any ethernet cards. 3)Each time I plug in the LAN cable , the network icon would say "connecting" and ultimately result in "disconnected.Now in offline mode".My ethernet device is Realtek PCIe RT8101E/RTL102E (rev 02).
I also tried to install the realtek driver though I was not confident whether I did it correct.
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 had shut down my laptop at work last week and when I booted it up the wired internet connect was not working.The wireless connection is working (I'm typing now via wireless).I have WinXP Pro on this machine (but I've never used it--I'm all Linux now). So I booted into WinXP and turned off the wireless and got internet connection through the ethernet cable, so it doesn't seem to be the cable or my ethernet card.Here is the output of "ifconfig"
Code: eth0 Link encap:Ethernet HWaddr 00:1c:25:7a:fa:b6 inet addr:xxx.xxx.xxx.xx Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.0
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 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 new to OpenSuSE and have just booted up an Acer Aspire 4736z laptop with the 11.2 livecd. All of the specs (gathered from lspci -n) are available here: Debian HCL - Acer / Aspire 4736Z. Wired internet does not work. I have tried `modprobe atl1e` then `service network restart`to no effect. NetworkManager says nothing is plugged in (perhaps a hotplugging issue?). eth0 is listed in ifconfig.
I have a Dell Latitude D530 Laptop (500 GB HDD). Installed Windows XP and then Ubuntu 10.10 to do dual boot. everything works fine in Windows XP.In Ubuntu 10.10 I had issues connecting to Internet(Through Wirelss), I was able to rectify this issue by dsiable ipv6 from firefox about:config and setting true to network.dns.disableIPv6. After this I was able to connect to internet and browse websites from Firefox.But I am having Issues with Evolution Mail(Connection Timed Out) and Google Talk Client(Connection Timed Out).Empathy Internet Messaging gets connected fine.I was wondering if I will have to disable IPv6 System wide and hence I added the following lines to /etc/sysctl.conf
I have a strange problem for internet. My clients (winxp - S2) can't get internet.Let me explain my scenerios. Fedora 10 with lan (eth0) having direct internet from dsl model, client (XP service pack 2) can use samba shares using dhcp (wlan0) installed in Fedora 10 box. client can ping my linux box.Now problem is: client (dosbox) can ping the google ip address (i.e ping 184.108.40.206) but can't use 'ping www.google.com'. That means ping with ip works for internet from my client. My linux box can. I can use internet from FC10 but can't use iexplorer from my client to have internet. I have enable ipmasquarding in Firewall and dhcpd is running on wlan0 for dynamic ip address of my clients.Can someone suggest me what kind of problem having I? What should i do to success iexplorer for internet? what possibly am i missing?
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%.
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.
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 recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.
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 use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
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
I have been running Natty on my MacBook Pro for a while now and then suddenly while just using it normally (not installing etc), my skype crashed and would crash again on restart of the program. Now this could be a red herring, but though I'd include as much info as pos.
I installed all the updates the system told me to, to see if this would help and restarted.
On restart, the wired network would not connect. I get the following errors in my log:
May 26 12:46:40 richard-MacBookPro NetworkManager: <info> Saved default wired connection 'Auto eth0' to persistent storage May 26 12:46:41 richard-MacBookPro NetworkManager: keyfile: updating /etc/NetworkManager/system-connections/Auto eth0 May 26 12:46:41 richard-MacBookPro NetworkManager: Ifupdown: get unmanaged devices count: 0
ipconfig does not exist on my computer, otherwise I would echo this for you also.
