Ubuntu Networking :: Internet Stopped Working While Connecting With Wifi?
Jul 22, 2011
I am using Ubuntu 11.04 desktop. I a, using my internet through wifi and it was working fine but suddenly it start strange activities... like when I restart ubuntu it work for few clicks but then suddenly stopp even wifi is showing connected but I cant use internet.
This morning my Karmic desktop stopped connecting to the internet (Firefox & Evolution). Network is all ok and other machines can connect fine - in fact I am typing this from a Windows 7 virtualbox running on the offending machine. Investigation shows that this is definitely a DNS problem as I can connect to sites / mailservers by using the ip address. Have tried several reboots which did not help. PowerDNS is installed. When I restart it the ff output is send to syslog:
I've been running ubuntu on my Asus 1001ha netbook for half a year or so. I ran Karmic for at while, wifi working and all, accepted the recommended updates when Update Manager popped up and everything was fine until one day I let Update Manager do it's thing and my wifi stopped working.. Lycid had just come out that same week, so I thought "screw it" and installed 10.04 instead..
So I've been running 10.04 for a couple of months now, everything working fine, including the wifi - until today.. Update Manager suggested some upgrades, I accepted and *pouf* my wifi is gone again..
That's the second time Update Manager knocks out my wifi, any way to roll back todays update or how to the the wifi working again?
I have a laptop that was working fine with 10.04 LTS. Today, I did a full 10.10 install and now my wireless is not working. Thinking it had to do with 10.10, I did a full install back to 10.04 LTs. Wireless is still not working. I tried installing the driver for my laptop's internal wifi using ndiswrapper, but that didn't work either. I have another laptop that is identical to the non-working one, with the exception that it is running a Celeron processor and non-Nvidia graphics. Otherwise, they are identical with respect to the wifi adapter. The Celeron machine is giving me absolutely no problems.
Since I originally started using Ubuntu (10.04) I have had problems with my wireless card. Now I have updated to 10.10 and it has stopped working entirely. I am using a "Dell Vostro 1520" with an "Intel(R) WiFi Link 5300 AGN" wireless card.Here are the details: 10.04
In this distribution version, if I had the wireless switch on my laptop activated at startup my wireless card would refuse to activate. There is a light to show when it is activated and this was off, but I checked anyway and wireless capabilities don't work when it is in this state. It didn't even resolve the problem when I switched it off and on again (although this caused the wireless indicator to blink on for less than a second when switched on).This was manageable because I found two workarounds:
1. Wait until my laptop had logged into Ubuntu, then activate the wireless card which would start and work as it should.
2. If I had already logged into Ubuntu I could put my computer on standby, switch off the card, come out of standby and reactivate the card while Ubuntu was running.As I said, this was completely manageable, and I got used to it. 10.10
Now that I have upgraded to 10.10 all workarounds fail, I can't use a wireless connection in Ubuntu, as my card won't activate, I cant even get the light to blink as I could before. The only way I can use WiFi is by switching to Windows.I tend to use Ubuntu for my university programming work.
I had 10.10, and all was well. Then I installed natty, and WiFi worked for a while, then stopped working. I later went back to 10.10, and WiFi still isn't working. The WiFi icon in the top bar looks like it's scanning. But it just keeps on scanning, continuously. Then it asks me for the password, so it obviously connects to something if it knows the network needs a password.
But here's the weird thing, my router also creates a BT Open Network, which I think is some pay service that BT offer, apparently through anyone's wifi since it's not password protected. I can connect to that. But not the actual network that leads to the internet. This happened a while back, and of course I can't install any updates on it because I can't get online. I am writing this from XP on the same computer, and XP can connect to the network no problem.
i have a dell 1501 that has been upgraded from 10.10 to 11.04. everything was working okay. and then the user ran an upgrade recently. subsequently the wifi has mysteriously stopped working. it connects okay if one plugs it directly into the router but the wifi seems to have just stopped working.my mini 9 connects fine to the netgear wifi router using wireless.when i run the system tests for networking i get the errors..."root could not find def gateway info /proc""root could not find default gateway by running route"here is the output from some diagnostic commands.NOTE:this is similar to a post titled "wi-fi dead?" but the output is not quite the same...
lauren@lauren-Inspiron-1501:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions.
I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the problem.
I'm currently running Ubuntu 9.10.After I updated to 9.10, my wireless connection stoppped working. I can access the network but I get no response or what so ever in my browser.Downloading language support or any software doesn't work either.Haven't changed anything to my settings and checked the router. Router works just fine.
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
my Internet connection stopped working suddenly after updating the packages using synaptec package manager and rebooting it..can anyone say me why did this happen.BTW,mine is ubuntu 10.10 and i am absolute new to linux.I had to configure my n/w connections right from the scrap again
running ubuntu 10.10 on a toshiba laptop recently the wireless Internet stopped working from our netgear router, it still works for the Ienova laptop and emachines desktop using the router but this laptop will not work wirelessly internet cuts in and out on this laptop when on wireless when it didn't previously do so it reads a connection but will not load up web pages unless hard wired in with an ethernet cord.
im not quite sure how to succintly say what is happening. the general idea is that my internet stopped working and I dont know why. I have a netbook that i am using while i am backpacking through asia. it has both ubuntu netbook ed, and winXP dual booting on it. out of the blue, i could not aquire an ip address through dhcp. This was true in both windows and linux, AND true while using either a wireless or wired connection. ok, that is odd, but not a big deal, i will just set the ip / subnet mask / gateway / dns manually. After doing this the computer reports properly connecting to the internet (did the same tests and got the same results in both nix and winxp), however I could not do anything on the internet. could not ping, nor do a dns lookup much less anything else.
scraching my head I looked around the internet for a solution and came across 'netsh int ip reset' this is a command I typed into the windows command line. I'm not sure what it does, but it worked so far as now
Working with a Dell Inspiron 6000 and installed Ubuntu 10.10 just to get familiar with some form of Linux. The wireless card is Dell's 1470 and the chip on the card is labelled BCM4311 so that's what I went for. At first it showed an unconnected wired NIC and for wireless it said "no firmware", but now it doesn't say anything about either one of them, it says "no network devices available". I followed the instructions here [URL] for both "STA - No Internet Access" and "b43 - No Internet Access" and when it says to go to the additional drivers menu to enable the new driver, there's nothing on the list. I then tried [URL] that guide and [URL] that one. Don't say things like "just run a qf13 on the PCL so the ergotron bus will be cleared, it's probably a thermawhatsit in conflict with the meatloaf kernel" as I won't have a clue how to execute said instruction. More useful would be "open a terminal and type 'ireallyenjoynewcarpetting' then check if the output says 'blargh 010101' ".
I have an asus EEE 1015N. Everything worked fine yesterday. I packed my computer, and went back home. After turning it back on, not only it didn't connect to the wifi network, but it did not even detect it. I know it's not broken or anything like that because when I boot into windows it works fine.I've been trying every solutionven in the "sudden wifi problems" threads in the forum (including checking the wifi power button, and trying to manually assign an access point to it), but to no avail.
I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.
i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

Only been using linux for about 2 weeks now. Yesterday my internet worked without a hitch now today all of a sudden it wont connect. I had the "Install problem! The configurataion defaults for gnome manager have not been installed correctly" so I deleted my music directory and now it boots fine, dont know if that might be part of the issue/ I dual boot win7 and i can get wireless on that partition but not ubuntu
I boot up, internet doesn't work. What do I do? I get the internet icon with a read exclamation mark on it and by default "enable networking" is disabled. This is the second time it has happened to me.
From one day to the other it crashed... So, I've deleted the link and when I try to install it again the PC failed to detect the device... But it works on windows... Even when I try to put my card on a device of the same operator, it works in a Toshiba with Ubuntu 10.10 but not on mine PC... I've an ASUS F3Sseries and all of the updates installed
My brothers computer uses Ubuntu. All of a sudden the internet stopped working. So I did some research online and found a site that looked like it would work because the comments were good. I did what it said by removing the network manager and then i had to re-install it blah blah blah. Long story short his computer is still without internet. I tried to download the network manager on my computer and install it on his computer. I dont think it worked.If anyone could help me find the correct network manager to download for his computer and then help me get internet back onto his computer.
I've happened across a wireless router that has a gateway address of 192.168.0.1 and allots IPs from 192.168.0.64-255. My laptop wouldn't connect to it automatically, so I was playing around and found that it needed 0.x instead of 1.x. I thought the network manager on ubuntu would have figured that out?! Now its a separate story that the router happens to have no admin password
I just installed ubuntu 9.10 in my freinds laptop and it has a realtek 81878 wireless card...it detects the wireless networks but when i connect it just keeps on asking for the authentication key again and again.
I updated successfully to 10.04 via wireless, then I downloadsynthesizer via wireless. The next day, today that is, can't get wireless to work. It keeps prompting mor the passphrase, I enter everything correctly, all the other computers in the house have no problem.
I am working with ubuntu (gnome) 10.10 maverick 64 bit on a HP pavilion 2713ca. I have installed the Broadcom sta driver for a BCM4328 wifi driver. After setting wpa security with my password, the wifi network worked for many weeks. However, in the last few days it does not connect no more. I have tried to reinstall SSID. And I have checked to see if eth1 was still there:

I'm using a HP mini netbook, and I recently installed Ubuntu on it. I updated and did the whole proprietary drivers activation and it now scans and sees networks but I am having trouble actually using them now. It says that it is connected to a wireless network but it never loads any pages.
im using minimal ubuntu 10.04 and im having trouble connecting to wifi using the terminal. the wifi worked perfectly on the desktop version. i followed this guide [URL] and looks like then i used '/etc/init.d/networking restart' and get this now it seems ive disabled wlan0 as $ sudo lshw -C shows
i tried to enable it again by using 'sudo ifup wlan0' but i get a few errors i think the 2nd errors may be because i tried to download another driver for the wireless using 'wget [URL] and then 'dpkg -i rt3090-dkms_184.108.40.206-0ubuntu0~ppa1_all.deb'
