i installed and ran System Profiler & Benchmark ran a test. then i rebooted and turned off ACPI/PowerNow. at this point i realized my network card had gone down so i went back an turned the ACPI on. nothing changed.
View 1 Repliesmy eth0 suddenly stopped working on FC10. i have been using it the whole time, and now it refuses to even ping the gateway. dhclient is not receiving a dhcp offer and when i put in the information manually, it is not even able to ping the gateway. netstat -rn shows that the destination of the router is going nowhere.
i do not think it is the hardware/software, but rather maybe the provider? i am from central europe but just moved up to great britain and working at a friends place. i can connect the mac powerbook without a problem (it will get an ip with dhcp), but not the linux machine.it is a normal ethernet modem connection here. can it be, that it checks MAC addresses or even the computer names? the powerbook also has a really weired IP address: 77.102.xxxxx
i am not using network manager, but command line tools and have nm uninstalled. does anyone have a clue, what this could be about? i am not a newbie, but this is really puzzling me.....
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
I'm not sure what's going on, but I have two computers that both aren't working after I reboot them. When I boot up the machine and do ifconfig, eth0 is missing.If I issue $sudo ifup eth0 then the ethernet is working, but I'm not sure why I'm booting up without a connection. Even after $sudo ifup eth0The networking app that's in the taskbar is missing.looked at dmesg and it looks normal$dmesg | grep -i ethmy interfaces fileiface eth0 inet staticaddress 192.168.15.146netmask 255.255.255.0gateway 192.168.15.1

View 2 Replies View RelatedI am trying to get a network bridge configured but every time I make the changes and restart networking (or reboot) eth0 appears to come up OK but I can no longer talk to the outside world via it. With no bridge defined, I can talk to the web using either wireless or wired; wicd is configured to switch to a wired connection when available (got rid of Network Manager. It didn't recognise eth0(!)).
I want to use the bridge so virtual machines (LXC containers) can talk to the web when the machine is wired to the wireless router. Eth0 gets its IP address (192.168.1.4) via DHCP from the router and I want to bridge to another subnet, 192.168.154.n say, and the containers will have fixed IP addresses 192.168.154.101, 102, 103 etc.

I've got a 64 bit home server system that was upgraded from FC2 to 7, 9, now 11. I've now got a weird situation where dns inquiries will not work when I reboot the machine, until i restart eth0. When I reboot, I can open firefox on the machine, put in the IP of my dsl router, and look at it's settings just fine. All other internet uses, whether it's yum,squid, or etc. comes back with the usual name server not found messages. I've got thenetwork setup to use the named on this server, ( the web's a tad bit slower when I set it up to use ISP's windows nameservers, go figure).
Anyway, a few years ago I set up the machine to use the network service to bring theseinterfaces up. (I believe this was because the early versions on Networkmanger had some issues. In an attempt to fix this issue I reset Networkmanger start at startup, and reset up eth0 and 1 to be controlled by it.I then got namserver1=XXX.XXX.XXX.XXX in resolve.conf at reboot..(yeah they were really X's, I'm not hiding an ip here) I tried going intonsswitch.conf, found the line hosts: files mdns4_minimal [NOTFOUND=return] dnsand changed it to:hosts:files dns mdns4_minimal [NOTFOUND=return]No joy, I still have to do an ifdown eth0 and an ifup eth0 to get dns to work..
Ok, so eth0 is up and working great. eth1, however, comes up with a link light, however the packet counters in ifconfig remain at 0. Appears that eth1 isn't working.
Here's my setup:
-Dell latitude CPi laptop with 2 PCMCIA network cards and no built-in ethernet.
-Slackware v11
-eth0 is connected inside my router on my 192 network. Static address with good connectivity
-eth1 is connected on the other side of my router in promiscuous mode in order to listen to the traffic coming into my network.
Troubleshooting so far: I have switched the pcmcia cards between slots and regardless of which card is in eth0 or eth1, eth0 works and eth1 does not. I have also switched the card dongle between cards as well as the ethernet cabling between the cards. With any of the combinations eth0 works like a champ but eth1 does not, so I think I've ruled out hardware problems.
Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.
I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.
I successfully set-up an FTP server, that worked great and perfectly, but after restarting the computer, it has stopped working.None of my router's settings have changed. I restarted the vsftpd process.
View 2 Replies View Relatedpulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB
I have had ubuntu about a month now and everything has worked great up until now, I was surfing the web and all the sudden I lost connection. I tried to connect to the signal but got nothing so I did a reboot. After the reboot my wireless signal didn't show up. i right clicked the connection icon on the top taskbar and the enable wireless is blacked out to where i cant click it.
View 7 Replies View RelatedI have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).
When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?
Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.
However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

View 6 Replies View RelatedBeen searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).
I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.
I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.
View 1 Replies View RelatedI switched my FC11 system off yesterday. Turning it on this morning, NO domain names can be resolved anymore.I can ping IP adresses directly, and even get to them in FireFox if I type the IP address. However, typing any domain name at all fails. I cannot ping or SSH to any domain name, but as soon as I enter an IP, it works. I can ping the DNS server by IP that is set in my /etc/resolv.confI checked on an XP system using the same DNS server set in /etc/resolv.conf (which can also be pinged on IP from my FC11 system), on the same connection from the same ISP, and it works.E. g. without touching anything at all (and all updates are turned off) my FC11 system has stopped resolving domain names.I'm running 32bit FC11. The system has been working fine for more than 2 years.So it has spontaneously stopped doing DNS when I enter a domain name. Where can I start looking?

Bit of an odd one this. My ZTE MF100 (on O2) had been working happily on my 10.04 laptop, but today is not recognised - e.g. no device listed by lsusb, nor error messages in dmesg at boot.
Re-plugging the device after boot gives me dmesg errors:

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'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.
Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.
It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.
Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.
I'm using a different computer to post this thread, so I'm manually writing the output.
Code:
sudo iwconfig wlan0

Version: Ubuntu 10.04 Relavant hardware: P5QL Pro built-in ethernet, cable modem with linksys wireless-G router (although problem is with ethernet connection, not wireless)
One minute my ethernet was working, and the next it stopped working. The only thing that I did between it working and not working was install electricsheep from Synaptic and then I shut down the computer. When I restarted a bit later, no ethernet connection shows up.
I checked the cables, made sure they are in tight.
My laptop connects using the same ethernet cable fine. So its not the cable or the router.
I reset the router and the computer at the same time. Still doesn't work.
I don't know where to even start with troubleshooting this sort of problem. Everything to the extent of my computer knowledge seems to be working fine.
I managed to set up a PPTP VPN connection in Ubuntu 10.04, and it worked first time.This was about 3 months ago. It was working yesterday (Oct 05 2010), but when I came to log in to the VPN today it doesn't work. I tried the same VPN connection on my wife's laptop which runs Vista and it works. I have tried re-entering the details, even deleting and setting up from scratch via network manager. And yes I have the correct VPN plugins. what I should do. Is there a log file so I can have a look at it to see what the problem is. If there is where is it located. The computer is able to connect to the internet without any problems, just can't connect to the VPN. The only thing I can think of is that the update manager popped up this morning so a few things have got updated today. maybe something in there broke the VPN connection.
View 4 Replies View RelatedI 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.
