Ubuntu Networking :: Wired And Wireless Connection Not Working After Update
Jan 14, 2010
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.
After I updated ubuntu 10.04.3 and restarted my PC, something weired happend and my wired connection was completely lost. I tried different things but it seems that I have lost my ethernet connection. I only have ethernet card and the interface was set to eth0 which is not recognized anymore.
The /etc/network/interfaces includes the following commands, which btw I tried to play with a bit by commenting and uncommenting the lines but was not helpful (but this is the original one):
Also in /etc/udev/rules.d I deleted 70-persistent-cd.rules hoping that it would be automatically regenerated but it did not,
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 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 recently purchased an Acer Aspire 1410 notebook running Windows 7 home edition. I installed Ubuntu 2.3 and my wireless and network LAN connection is not working. I saw on a link in this forum, someone was having similar problem. However, when i tried the solution that was recommended/suggested to the person, it did not work for me.
what I can do to get my wireless and wired connection to work?
I have an old Compaq Presario v2000 that recently had Ubuntu 10.04 installed on it. The wired internet worked when it was installed, but the wireless didn't. I tried to download the drivers for it and it failed everytime. I did an update thinking that the update might fix the wireless, but it didn't, it actually made my wired connection stop working. So now I have a newly installed OS on the laptop, and I can't do anything on it because there is no way to get any internet.
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
I decided to do a fresh install of 10.04LTS on a Dell Latitude D600 Laptopne wordDisaster I have no wireless or WIRED internet connection. After viewing another post I've provided the output of "sudo lshw -C network" command below (I've blocked out my MAC address on purpose). It appears that the lan card is not even being recognized. The card is enabled in bios (I've checked twice). I don't get it, the wireless worked fine before I did a fresh install of 10.04LTS. I can't use wireless because I have the b43 driver firmware issue that I can't resolve unless I get my wired connection working.
For the last 3 or so hours I have been trying in vain to simply give my mobile phone wifi internet access from my netbook. I have tried to google and follow some howto's and guides, but they're either too old or don't explain it very well. I'm fairly new to use of Linux and of wireless networks, but can handle setting them up in Windows. So basically, having said that, I believe I mostly understand how this whole thing is supposed to work theoretically but I just feel as though I lack the experience to jump the wireless hurdle AND the Linux hurdle at the same time. I have provided some information below.
- Setup is based on Lucid netbook remix install with a Maverick kernel update due to lack of driver support for wireless NIC - I can confirm wireless does work properly for connection purposes - I followed [URL] and kind of followed [URL however I couldn't even tell how to run Network Manager, even though Synaptic tells me it is installed - When I ran into problems trying to install ipmasq I found [URL] and followed what the response told me to which allowed me to restart the dnsmasq and the dhcp3-server at least - I have restarted the entire netbook several times throughout the process.
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.
As of now, my internet works fine when connected with an ethernet cable.The problem is it doesnt seem like my wireless is working at all.The led light is orange, (its usually blue when it connects) and I cannot see my home dsl network.Is thereany specific troubleshooting steps I should take?HP dv6000 laptopwireless card: Broadcom Corporation BCM4311 802.11b/g WLAN
I'm trying to set up a wireless or wired network (wireless would be better...) to share my connection with my housemate, as well as with some devices. The only guide I found regarding this (I must admit, I didn't have much time to put into research), was dating back to 2005, and although doable, seemed somewhat confusing. Getting to the point: is there a way (maybe a standalone program, or some kind of plugin) to share a connection?
I had windows and 8.10 earlier and now have single boot 10.04 !
1.) I can see wireless networks only after I am connected to the router through wired ! I guess its some thing to do with me activating ifup and ifdown, when my wired connection stopped working as i was trying to install wireless drivers.
2.) Even when I see wireless networks, i cannot connect to any of them.
I tried various things for a whole day trying to fix it and i doubt if i screwed up some thing that was running good.
I've been running Ubuntu 10.10 on my Dell Vostro 1500 for awhile, one morning I tried to get online & no networks would show up. I tried plugging in my ethernet cable & still nothing. Just the two lights by the plug stay lit up. If I boot into Puppy Linux the wireless works just fine. I was using the B43 driver before I had problems, then when I was trying to get it to work I accidentally deleted the driver. I cannot figure out how to get my internet working again in Ubuntu. I don't want to be stuck using Puppy Linux forever! I don't really know many commands, normally just search online how to fix problems, but it's pretty hard to do when I have to boot back & forth between operating systems to find things to try.
I'm fairly sure that this is an Ubuntu issue, as I've tried this on my windows computer with success.I'm running a minecraft server on my laptop, previously over a wireless connection but the data rates were too slow. On a wired connection, however, the server starts up and runs like normal but the port is not open when accessing from the network's public IP. I tested this with canyouseeme(.)org. I can get to it from other computers within the network by using a local IP, which to me seems a little strange as it seems to indicate that the port is open on the PC but somewhere in the router it gets confused due to being wired(?). Obviously I've forwarded the ports on the router (BTHomehub 2.0) with both TCP and UCP (it worked over wireless!). Any suggestions as to what might be causing this? I'm stumped.
