I'm running Federa12 on my Asus EeePC 1005HA and I can't upgrade my system because my network connection flakes in and out. I'm connecting to the D-Link DIR-655 802.11n router. Any hints or ideas? I'd rather solve this than just plug-in the ethernet cable.
View 7 RepliesI'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.
Sometimes my file share network stops working,and will then work again.I'm lost with this problem. The server pc is a Zenwalk pc.The other pc is a win7 pc. This error only occurs on Zenwalk. When i run puppy from the live cd the file shares are always visible,without fail.Under puppy i use pNethood. When the ping command is used there is no problem, and the pc name can be pinged.This is shown below:

I'm having intermittent network failure on my laptop but I can't figure out why. I have a cable modem and a 10Mb/s (bits) connection (at least that's what I'm paying for). The modem is connected to a wireless router, to which my laptop connects wirelessly. Quite often my speed drops considerably-- sometimes as low as a few hundred bytes per second. Other times it fails completely. This will happen with just about any server you can imagine, including the Debian FTP mirrors in the US.
- When I do file transfers over the local network from my laptop to my desktop, they go pretty fast, around 2 MB/s. I believe my wireless card (Intel 3495) maxes out at 3 MB/s (bytes), so that seems reasonable.
- When I download a file from the outside network, it usually goes pretty fast too, around 1 MB/s, which is close to my limit.
So why is it that the connection between the laptop and the external network is so slow? I've tried power cycling, but it doesn't really help. I can't think of anything else to try.
Installed openSUSE 11.3 over an existing 'very stable' 11.2 installation and started experiencing wireless connectivity issues immediately. Network Manager would show connected 100% - 92% but I would lose connectivity to mail, browser and messenger(s). This disconnect would last less than 30 secs but would occur every 2 to 4 minutes.
dmesg reported:
[ 3663.672098] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 [1]

[ 3664.529050] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 [1]
BTW Channel 3 is the channel my wifi is broadcasting on. I've tried other channels and other computers and it is only openSUSE 11.3 having an issue. I am also using WPA2. Modifying the Global Options in Network Settings from User Controlled with NetworkManager to Traditional Method with ifup seemed to stabilize most of the issues, but I do notice occasional drops. I've also switched from Network Manager to wicd to provide some UI while dealing with this issue. Since iwl3945 drivers are now in the kernel I don't know if I should try to revert to an older driver or if there is another issue.
I am using FC 2, and I get 'eth0 failed' during startup.
I am configured for DHCP
device is 'inactive' under network device control after reboot
click 'activate', sometimes I can surf, others not.
When I can't get online, sometimes deactivating and reactivating works.
edited connection to 'activate device when computer starts'
eth0 still fails at start-up, and device is inactive.
I am supposed to use FC2 for my schoolwork
I have Fedora 13 installed on a new PC and have two types of intermittent boot hangups. What logs exist within Fedora 13 that may help me identify the cause or causes of these hangups? Todate, a reboot gets over the problems but I wish to get this sorted whilst the PC is still under warranty.

could anybody tell me , does the xen kernel has impacts to the cluster , or is this only a networking problem not a system problem? I monitor the switch mac table, find that , the mac of eth0 is always changing . so maybe it is xen kernel problem. I refer to some xen materials , the eth0 is a virtual adapter .and the original physical adapter eth0 is renamed as pth0 and works as a bridge .so how could I fix a mac address to eth0 ?
Estimating 10-20% of the time while booting I get an error like the following for USB partitions I am trying to automount in boot.log:
Code:

mount: special device /dev/sdc2 does not exist

From time to time I have no connection to the net after booting the machine. This is a wired connection that goes through a switch, then a router to a DSL modem. When there is no automatic connection, I can't connect manually either However if I re-boot the connection works normally.
The Network Connection indicates eth0 and eth1 are both set at "Auto" Strangely the "Last Used" column indicates "Never" for both even when I am actually connected, and on line.
Over the past two months I've migrated two NetWare servers 6.5 SP7 to SLES10 SP3 and OES2 SP2.'ve had some consulting assistance and been learning linux as I go. Now I have a b!tch of a problem with a Dell PE SC 1430 with integrated Broadcom BCM 5751 GB Ethernet working ok, but then after a reboot it will come up with no networking. I've used Network Manager to configure a static IP but it willsometimes come up and ifconfig will show no ip assigned.I can manually assigned ip, netmask, gw and can ping the gw, but can't ping any host on the subnet. I disabled the integrated NIC and installed another, but same problem.
View 3 Replies View RelatedIn the last week I have noticed that sometimes my Mobile Broadband connection just goes off without me doing anything! I have credit on the dongle account, so it isn't that. I'm using fedora 14 on an acer aspire one netbook. Dongle is a Huawei E160 on o2 here in the UK Kernel is 2.6.35.11-83.i686.fc14
Sometimes unplugging and replugging the usb dongle works. Othertimes, I have to leave it out for several hours. It does seem to happen daily, though.
For most actions on my system now it seems that clicking doesn't get a response on the first click. It can take 2 - 4 clicks at times for the system to react. Although I work primarily in my browser (Google Chrome), it does happen outside as well. I am running Gnome as the window manager.

Its getting to the point where I am having to consider recommending that we use windows instead, which I would rather not do as I think its good for students to experience different operating systems during school.
View 9 Replies View RelatedMy server is running Red Hat 4.1.2-44.I am having an issue with it hanging (website doesn't respond, can't connect via SSH (it's a remote server)) after 4am on every 3rd Sunday or so.A reboot is required to get the server responding again.I have checked every logfile I can find and found nothing that helps me. The thing I have noticed is that some of these log files start afresh after the reboot so my initial thoughts are that it is a logrotate issue or something similar.

I updated this morning to the latest bugfixes for F13. For some reason, networking has become un-available after the required re-start. I am using a fixed IP. Tried to add eth0 DHCP, which initially worked, but became unavailable after a few minutes as well. I suspect there may be an issue with the card's MAC address which may or may not be detected correctly.. Has Networking been updated somehow in this bugfix release?
View 2 Replies View RelatedI am not able to connect to network after update F13 to 2.6.34.7-61. Because there is "no netwokr decvice" IAW network manager. There is nothing in system log that abonormal. But, there is a fail initialization in the boot message. "applying firewall rules: iptable v1.4.7:Ip6table-restore: unable to initialize table .filter error occur at line 3 try Ip6table-restore -h or Ip6table-restore -help for more detail"
so, I tried the comment at terminal with root clearance, it just give some feed back about how to use this command. When I tried out other options. none of them work. There is no feed back form the terminal other than previous display and blanking cusor.
I assume it was the firewall preventding me to connect to network. And I complete disable SELinux and reboot. Problem remain, no network device. Check network device driver. There all inplace. Tried using old kernel, unble to boot up X window, presumably old driver has been deleted.
BTW, after two consecutive update failure (2.6.34.7-54 kernel panic VFS? problem, 2.6.34.7-61 no network connection), I assume Fedora Quality should consider review their update release process. Since the probability of fedora releasing bad update is increase a lot after fedora 11.
I have Fedora 10, and today I finally had an opportunity to let the automatic software updates run. At the end it said to restart the pc. I restarted and now it won't connect to the network. What do I do to get it connected again?
View 5 Replies View RelatedThe latest update totally screwed up my system on KDE.The KDE network manager says "activating network", "networking system disabled", "connection failed".The icon shows 3/4 progress completed and is stuck there. Any attempt to change connection manually leads to plasma-desktop crash. I know this is only update related because I have messed with system earlier and thought that the network failure could be my fault, so I reinstalled the system and ran only update command, after the reboot the system was again in the fubar state. This is really frustrating. Just feels like really poor update testing. I have Fedora installed on three different systems however, I won't update them until the problem is fixed.

I just installed Fedora 12 x86 in an Acer Aspire One D250. Everything ran smoothly and was detected upon install but unfortunately after all updates were applied to it I ended with a device with no network connection (not even Ethernet).
This appears to be kernel-related because the old kernel (stock) works as expected. The problematic kernel version is (2.6.32.9-70.fc12.i686).
Is there any known workaround for this? Or am I condemned to run this older kernel until the other one gets fixed?
Another question, in the event a new kernel comes out I'd like to keep to older one as a back up, how can I arrange that?

I tried to do a scheduled software update several times today (8/20/11) and nothing seems to download, though I do get the "Downloading" PackageKit dialog message (the System Monitor shows practically no network activity). In between tries I downloaded some 600 MB .iso files (about 10 minutes each) so I know my internet is working properly. That leaves either PackageKit got hosed in my last update, or servers are down.

View 9 Replies View RelatedI have Ubuntu running on a Compaq desktop. Version 9.04 ran great but since upgrading to 9.10 it intermittently locks up. There is no rhyme or reason to the timing. Sometimes it is immediately after logging in but usually it is after the system has been running awhile. Sometimes it happens when I'm actively using it and sometimes when it is idle. It has never happened at the login screen, no matter how long I leave it.
Note that it is not a complete lockup. The mouse cursor moves, but no longer functions (i.e. you can't click anything). The keyboard does not work at all. For example Ctrl-Alt-Backspace and Ctrl-Alt-F5 do nothing. Disconnecting and reconnecting the mouse and keyboard does not help. Also, I can still access the system over the network using SMB and SSH, which leads me to believe that X or Gnome is where the problem lies.
Here are the troubleshooting steps I have done so far. As I said I can access the system using SSH, so I logged in and ran "top" to view CPU utilization. I found no process using more than 1% of the CPU. Also I examined the messages log and found "segfault" errors related to libc (?), USB and my keyboard, so as a test I traded my fancy wireless keyboard for a generic one. That has not helped. I'm not sure where to go from here. I've examined other logs but it is all Greek to me. There are entries that sound as if they could be errors but I'm not sure and the times of the errors don't match the times of the lockups anyway.
This was originally posted on the Ubuntu forum, but someone suggested it might be a hardware problem, so I've re-posted (and updated) here: Quote: Originally Posted by Girts My shiny new Dell has developed a booting problem over the last few weeks. The Dell splash comes on for up to 10 seconds, screen turns Ubuntu purple for up to 20 secs, then 'no signal' message is displayed by monitor and screen goes black. Hard drive light goes off, mouse and keyboard don't respond.
When the Dell engineer came to replace a suspected failing hard drive, he realised the noise was coming from the fan on the graphics card (ATI Radeon HD6670). I mentioned the PC was reluctant to boot first time, so he replaced the whole graphics card. However, the PC is still intermittently reluctant to boot first time (3 tries a few days ago, but OK since).
Before I call Dell again, I want to be sure it's actually their problem and not a Ubuntu/Linux thing! I'm not fluent in Linux, but has anyone got any thoughts on this?
I've just installed OpenSuse 11.3 on my two Sony Vaio VPCF11Z1E machines (which have a Geforce GT 330M graphics card).Both machines appear to setup correctly and behave normally, but at seemingly random intervals (of the order of magnitude of 15-30 minutes) the whole system locks up for no readily apparent reason. I can still move the mouse pointer around the screen, but I cannot click on anything, and the whole keyboard is unresponsive (including any reasonable ctrl-alt-xxx which might normally help). The only way to get out of this seems to be to press and hold the power button to shut the whole machine off (which is not ideal!)
