I have an issue on a few servers where IPv6 stops working after a reboot. I can ping anything within the same subnet but anything outside of that it gives me host unreachable. I believe that it is not routing for some reason, but I am not sure why. I have tried adding a default Ipv6 route for Eth3 but nothing seems to work.
uname -a

I'm having some problems with wireless, it works fine on boot but after a while pretty much randomly, it can be a few days or it can be a few hours, it stops working. I'm not sure which command would tell you what and it would take a little while to debug it because like I said it's random, but if anyone knows what to do please tell me! I'm on Lucid Lynx 10.04.Another something that's really bothering me (But not related to wireless) is that for some reason when I restart my computer, the top panel keeps changing the applets locations.

need to restart computer to get wireless back.
or even a command to run to restart the wireless (/etc/init.d/networking restart doesn't work)

This should be easy for the Ubuntu Gods to sort out:
I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.
My Ubuntu when i start it up, go to the wireless networks , try to connect to my network it trys to connect stops than says disconnected. My internet card is a Cisco Aironet wireless (idk the model number)
View 1 Replies View RelatedI have a wireless network using this driver:
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
I have install fedora11 live and the mouse work well when installing.When you reboot the mouse works ok until the welcome screen apears then the mouse stops working and I cannot continue with the postinstall.

In most cases, after that, I'm loosing the internet connection. I can't open any website, can't ping the router (which is my default gateway) and now it happened even without any error, which really pissed me off. Logging out and back in doesn't help, I need to make a full reboot to get back my internet connection.
Under Windows 7 everything is working fine and I'm not having any trouble with the internet connectivity! I had Fedora 11 32-bit before and it was also working normally!
Initially it was working fine after fedora 15 install.However recently it simply stops responding after a period of time.After reboot, sometimes it does repair itself but again stops working after some time.I'm not aware of any package updateperformed or configuration change that would have impacted it.And it does work intermittently as mentioned above
View 2 Replies View RelatedI have a problem with my wireless connection in ubuntu (natty with amd64bit) There seems to be intermittent disruption in my connection. Havent seen a pattern as yet, though it happens once a day. After that I cant get it to work at all and only restarting + reconnecting the USB device helps. Dont know what is going on.I have already read these pages : Commands and Wireless Troubleshooting.Here is my line of though1) Given that I am able to connect other devices to it while I am not able to connect through this desktop, I think the router is OK.2) I am able to work with it after restart + re-connection . And so the driver is OK and is loaded. The driver seems to be oK and loaded even while I am not able to connect.So why is this happening and how can I get this under control without having to reboot and re-connect the device everytime.Here are the output for the commands which will give you a more detailed idea of the process. Before reboot while I was not able to connect:

Im having problems with Ubuntu 10.04. My wireless disconnects frequently and firefox seems to stop working. it seems the connection times out sometimes when firefox stops. other times the connection just disconnects. When I was running 9.04 everything worked and nothing disconnected, so I know its not my computer.
My laptop is an IBM t40, 1.4 ghz, 2gig of ram.It does not seem to mater if Im using the wireless or the wired connection. The problem happens either way.does anyone have a solution for this?
My Acer's Wireless randomly stops working until you fully shut down and start the computer.(Not Restart but Shutdown->Powebutton) I am using Ubuntu 10.04 Lucid.
I am wondering if anyone knows why it would stop working properly, and/or how to fix it?
And since this is a off and on problem I might not be able to provide details immediately from time of crash, since I need my computer on the wireless.
One symptom that really stands out is that the cooling fan is spinning as fast as it possibly can and processor usage is spiking around 80/200 on a process called phy0.(relevancy unknown)
As I was typing this post on my other computer, my laptop crashed and I lost the lshw -C Network output I had. If asked to, I will post the one from when it is working. Also I will post any other info you need from when I can.
I'm running a Source Dedicated Server on my Ubuntu laptop, and to connect to it via external IP from other computers in the network I need to enable loopback in my router.This was working fine, but then I disconnected my laptop for a few days, and when I came back the wireless stopped working on my Xbox. I reset the router to factory defaults, and then setup everything again. It was all working fine until I enabled loopback again and power cycled my router. Now every time I do that, the internet on Ubuntu stops working and the wireless on the Xbox stops working.
Edit: You can ignore this I guess. It seems I was actually DISABLING loopback by enabling that router option, which I guess caused this. Strange, because the first time enabling this option was the only way to get my external ip to work. Oh well, everything is fine now.
I use a Kensington Wireless Netbook Mouse.It has worked well in Ubuntu 9.10 and 10.04.For some reason in 10.10 it works, but every now and again it sticks for a second or two. Sometimes the left button stops working.If I pull out the dongle for the mouse and put it back in my mouse works fine.

I upgraded from 9.10 to 10.04 and my wireless card no longer works.
The card is a Dell 1450 USB a/b/g card.
lsusb sees the card. device id is 413c:8104
dmesg says that p54usb is trying to load firmware isl3887usb but that failed (error -2)
I looked in /lib/firmware and didn't find that file
ps. god why did i upgrade?
I have a Dell E6500 with and Intel 5300 wireless agn card running Lucid x64. Wireless works fine and speeds are great except when I download with either the browser or thru a torrent or even updates. Once I get to around 100 megs in to the file wireless stops working and the only way to get it working again is to disconnect and reconnect to the AP. I have installed the back ports and tried several other fixed to get this to work but nothing has helped. One more note this happens on 2 other wireless routers that I have tried so I know that it's not limited to my Linksys.

I am currently dual booting between Linux Mint 10, and Windows Vista SP2. Wireless works fine in both these OSes, but when I quit Mint and load Windows, 70% of the time my wireless stops working.
ie, it does not detect any wireless networks nearby, althought there are tons of them.
Restarting the wireless device doesnt help, I have to restart my computer at least 4 times for wireless to start working again.
And as of now, my wireless in Linux Mint has stopped working.
My wireless LAN connection on this machine occasionally stops working. The network traffic bar shows periodic very small transmissions but the failure of all network dependent applications (Firefox, package manager, etc.) indicates to me that the machine is no longer talking to the net. I can fix it by reselecting my home network in nm-applet from the drop-down list. This causes the machine to disconect, reconnect and all is well for some random period of time thereafter. Here's some data:I'm running an HP Pavillion laptop.

I don't know if this is related or not, but a couple of months ago I unsuccessfully attempted to share a hotel's wired Internet connection over my wireless card. I may have hosed some settings or it could be unrelated.The "unknown interface" portion of the restart attempt is interesting but I don't know enough to fix it.
I'm using a Vaio TT, which seems to use an Intel 5100 WiFi chipset, and a Linksys WRT54G2 (firmwares 1.0.1 and 1.0.4), ubuntus 10.10 and 10.04.
Wifi works fine out of the box. However if the other vaio tt in our office (running windows 7) comes online, my laptop stops being able to make new connections. It WILL stay connected to chat servers, and downloads SOMETIMES continue to work. However all new HTTP requests / ssh connections / rdp connections / pings fail. The laptop still appears to be "connected" to the wifi network.
This may also happen after an undetermined amount of time without the extra vaio. It is not solved by reconnecting or rebooting. Once the extra vaio leaves the building, everything works fine again. This problem does not happen at all if I boot into windows.
I am using opensuse 11.4, libvirtd 0.8.8, virt-manger 0.8.5.
If I want to reboot a virtual machine (typing 'reboot -n' in the VMs console) the virtual machine stops insteads of reboot.
The virtual machine is also opensuse 11.4
Afterwards I have to click 'run' in virt-manager.
Then the vm starts and remains running til the next reboot.
If I try to reboot from comandline by typing 'virsh reboot <vmname>' I get the message
error: Failed to reboot domain <vmname>
error: this function is not supported by the connection driver: virDomainReboot
What is wrong with my setup?
I installed Fedora 13 to sdb7 and installed Grub to root all went well on install. But when I reboot it stops at Loading Partition.
View 12 Replies View RelatedI have a problem with LVM. My installation of Fedora 13 is on 2 SATA hard disks, which are set as /dev/sda and /dev/sdb. On sda there are two partitions (boot and a physical part of the volume group) and on sdb is only one partition (other physical part of the volume group). Both physical parts of the volume group are used for one volume group and the VG is splittet into multiple logical groups. The system works and all seems to be ok. But I saw a strange thing on last reboot:
The device /dev/sda was not recognized during the boot sequence, instead the system has build a device /dev/md126p1 with the same geometry and partitions and it has the same disk id as sda.
The volume group is also ok, the system boots into the desktop environment, but the system-config-lvm says that /dev/sda is not initialized and the volume group consists of sdb and md126p1. fdisk -l knows three devices (sda, sdb and md126p1). I think, that is the reason for my problems with preupgrade, which stops after the reboot with a LVM problem (root not found). Can I correct that without data loss?
Sometime after I upgraded to ubuntu 9.10 I've been having trouble with my wireless network connection.It will usually log on to the network, then disconnect a shortly after. Then try to connect again, usually successfully, then it cuts off again. Then connects again, then disconnects. FWIW, ubuntu 9.10 works on a different machine pretty consistently, so I don't think its a problem with the router.

Short Version:
Code:
I have Ubuntu 9.10 installed on my laptop. The laptop has a single HDD with 2 partitions. Partition 1 has WindowsXP and partition 2 contains other data, among which the directory of the ubuntu installation. The partitions are formatted as NTFS. Ubuntu has been installed with wubi on the second partition. Ubuntu has been working fine for 2 days. Last night I updated the Ubuntu system and it required a restart. Needless to say, after the restart, grub wouldn't load. It just shows the shell.
I read the threads inside this forum and people usually manually select a kernel and boot up ubuntu, but when I do this, after I input all the commands I input "boot" and hit ENTER. The computer starts booting up until a point when it says ALERT! /host/ubuntu/disks/root.disk does not exist and something about using selection #1 and exits to shell (Easy Shell or Easy Boot, I can't remember exactly what it says... Easy something anyway) I've read that this is possibly caused by a NTFS dirty tag... but I do not see how to fix this problem.
