Fedora Networking :: Random Disconnections From Wireless In F12
Jan 4, 2010
I am using Fedora 12. I am able to connect to my wireless network (95% of the time at least) on start-up automatically, however after anywhere between a few seconds to a few minutes later it cuts out and will not reconnect. It appears to be that whenever it finds next doors network it disconnects from mine! I have set the channel to 9, and my neighbor's is on 1. I have a USB N+ adapter, and a G+ MIMO PCI card, however do not know which is being used to connect with.
I'm trying to get wireless working in F10. Using pci wireless card with Atheros chipset. To be sure, I tested this hardware with a PCLinuxOS Live CD. Connects to AP perfectly.
Hardware drivers seem all OK in F10, and ifconfig shows wlan0 as expected. When I use the Wireless-Assistant 0.5.7 there's no connection.
Actually, the AP logs show numerous connections and disconnections.
Preferring CLI, I'm using a drop-dead simple wpa_supplicant.conf as follows :
Should Ipost some debugging output from wpa_supplicant -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d
Has anyone experienced random wireless dropouts? Like one minute, you are connected and then not, with no obvious reason as to why it happened, just network manager popping up requesting a password to reconnect.
I use ubuntu 10.10 and disconnects from wireless at random. after it reconnects the the connection speed is very slow and unstable. It's not my router because it works fine on my sister's netbook (which is also running ubuntu) and it worked fine when I was running windows? I'm not very advanced with linux so you know. I don't have IPv6 enabled. My laptop is an "Advent QRC430" my wireless card is QCOM Q802XKG Wireless Network Card.
I have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behavior when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information. uname -r

I have this weird issue which only appears when I am using 64 bit Ubuntu. Every now and then my laptop seems to go into a kernel panic (system unresponsive, numlock and scrollock lights flash repetitively) only when I am using the broadcom wireless. I can connect to my wireless router and use the internet and local network, but eventually, kablamo, crash, bang, boom. The only way out of the crash is to power off completely. After repowering, the wireless network is fine until the next crash. There does not seem to be a pattern or time period to cause this crash either. I have purged network manager(which I couldn't get to use my wireless) and am using wicd, which allows me to connect wirelessly.
So... as I tried to connect to the internet i saw a load of garbled characters as names of wireless areas. I took pics w/ a camera (because I suck and don't know how to take screenshots) and I'll try to get them up. Its all nonsensical and is really making me concerned about the state of my computer. [URL] That link contains pics of my issue.
I have my laptop dual booted between Ubuntu 9.10 and Windows 7. In Ubuntu I randomly lose connection to the wireless network. It always works fine when I first boot into Ubuntu but after a while my wireless connection will go down. The signal strength meter will go to zero bars and the black popup message will appear that my wireless connection has disconnected. At first, if I just wait a bit, the connection will come back. However, after about 4 or 5 times of doing this it will then ask me for my password, and inputting the password does not reconnect me to the AP. I am finally forced to reboot. Then it works OK for a while again and the cycle repeats.
It works fine in Windows7 all day, every day. I have the Release Candidate of Windows7 so it's going to expire soon. I would really prefer to make Ubuntu my everyday OS on this laptop rather than pay for a Windows7 license but I cannot tolerate a flaky wireless connection.
I had 8.1 on this laptop at one point and I never had any problems with the wireless then, that I can remember. I had no Ubuntu for a while but then I came back with the 9.1 and was loving it until the wireless problem reared it's ugly head.

with the same router, same ISP, same connection basically, on Fedora I'm getting on a maximum of 60 mbps. I also get moments where no pages will load, but network manager will report that nothing is wrong and that the connection is 100%.
I have installed Debian Wheezy on my laptop today, which went relativly smoothly. The only problem that is left (for now) is that my wireless LAN disconnects 1-2 times every 30 minutes, just to reconnect a few seconds later. Obviously that is very annoying, especially when watching streams on twitch, videos on youtube and so on.A thread I found on google suggested to use the command dmesg right after my wireless lan connection drops. So I waited for the next disconnect, issued the command and got the following output:
Code: Select allwlan0: deauthenticated from 00:1f:3f:d4:25:6a (Reason: 14) wlan0: deauthenticating from 00:1f:3f:d4:25:6a by local choice (reason=14)
I wondered what that reason code meant and found this website, which states that the code 14 stands for: Message integrity code (MIC) failure
I have a wireless keyboard and for some reason it is typing random letters, symbols, and numbers while I am not even touching the keyboard. I tried a different wireless keyboard and that worked for awhile, but even that started to do the same thing. I plugged in a cord keyboard and that has been working fine, but I am unable to type my password if it goes into sleep mode or select my windows partition. It's very confusing and I plan on reinstalling both windows and linux anyways it's that time, but I have to figure this problem out before I do.
I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.
I have set up a small Mesh Wireless Hotspot at a local Flea Market. My plan is to add in one of those HotSpot services for billing and such..ut until I have enough users to justify that expenditure, I am just going to manually set up accounts.The system is all up and running as an OPEN SYSTEM. Users are able to access the net just fine thru my existing setup.My question is, how can I create user accounts so that users of my wireless network will have a username and password that they can log in with
I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.
Recently I have installed Fedora 14 on my other laptop. It's a dual boot with Windows 7. Everything worked perfectly fine, networking included, until my friend didn't accidently turned off the wireless by pressing a wireless button on the laptop. Since then the wireless on Fedora doesn't work. It does on Windows thought. I've tried restarting the laptop few times, but the wireless still doesn't want to work again.
I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:
I am having a little trouble connecting to my wireless network. Running Fedora 10 32 bit.I'm trying to connect to a hidden wireless network. I updated the firmware for my driver but apparantly the driver is still not working. Broadcom has a driver from their website for Linux 32 bit systems. Should I attempt to install it? I read a post where the driver is built into the system kernel. If so I would need to blacklist the one of the drivers. Correct?

I'm confused. Why do I get a response from ping for any scrambled internet server name I type in??The only thing that is necessary is to start with "vvvvvv."(It should be triple W in this post, but I need to do this work around due to the forum rules )And it always resolved to different IPs with similar ping times.What's going on?

I installed Red Hat Eterprise Linux 5.4 Server on my HCL Server machine.I use a static IP for my server. The problem is the network connection is automatically disconnected for some times and it again connected automatically after some time. It happens in periodic manner.I check my cable, port and connection.Those works fine in other PC
What is the easiest way to make it so that these transferred files will not be completely locked out and require me to go and change them one by one sohat i can access them without having to go root. Also the "apply to all subfolders and files" doesn't work. Also trying to set the SELinux rule to "userspace" doesn't do anything else. Basically i was trying to do just that transfer my $home folder over to fedora but now it's being a bit odd towards me with making everything require root access and not letting me read/write all files and folders within them.
I am running Karmic AMD64 on a homebrew desktop PC, but I also previously had this trouble on 32 bit with different hardware and on Ubuntu 9.04 and 8.10. The router is now an ADSL+ Thomson TG585n supplied by O2 and badged O2 Wireless box III. The PC has a direct ethernet connection. The router was replaced by O2 when the problem first appeared, as the Wireless box II was suspect. However, I still have the problem and it is getting more frequent.
The symptoms are these: I generally shut down the PC each night, and only fire it up again when needed, which is usually the following evening, but it remains on for most of the day at the weekend. Very often when started, I find I have no connectivity to the internet, and cannot retrieve my emails. Strangely though, the Skype connection is still present and works, although not every time. My wife's laptop is connected over the wireless link - and that STILL WORKS! Sometimes I can connect to the router interface, but sometimes I can't. I've never lost the connection while the PC is running.
I have tried everything I can find in the router (when I can connect) and also in the Systemreferences:Network Connections and also in System:Administration:Network Tools, but can't find anything that helps. A re-boot of the PC doesn't help. A re-boot of the router doesn't help. A hard reset of the router on it's own doesn't help. The only solution to restore the connection is a hard reset of the router (using the recessed reset switch in the back) followed by a re-boot of the PC.
Since the Skype service remains working, and the lights on the router remain normal and wireless service doesn't fail, I think this has to be a DNS server problem. In the previous release, Jaunty, I changed the DNS service to OpenDNS within Ubuntu, overriding the router's settings. That seemed to help a great deal, although there was still the occasional outage which might have been another cause. I can't find anything in the GUI interface in Karmic that will let me do this, and I can't now remember how I did that in Jaunty.
I'm looking for a method to assign a default gateway via dhcp randomly depending on ether the last char of the mac being odd or even, or the time the user connects. Is there a good reliable way to achieve this?
I just installed Fedora 12. Now i've seen a few other threads but they seem to have all the conclusion that its the Nvidia drivers at fault. Well i have an ATI Mobility Radeon 3400 series. I can login, and navigate for a little bit, then it just randomly freezes. I've booted to both gnome and KDE, kde freezes almost immediately w/o letting me navigate much. Gnome takes a bit and then freezes on me. I managed to login once and go like 6 minutes then i thought it was worked out, rebooted and boom, froze up again. I can still move my mouse but can't click or use keyboard. Ctrl+Alt+Backspace doesn't work either .....
About a week after I installed F12 on a brand new system, a friend came over and went on to play poker on facebook. At some point he yelled that the PC froze. I was working on another machine at the time and tried to ssh to the supposedly hung system, but couldn't; Except for playing poker he had audacious open and about 3 seconds of the song that was playing at the time of the hang, kept looping. Neither Ctrl+Alt+Backspace nor any of the Alt+SysRq combos had any effect whatsoever, so I had to press the reset button (and I have to say this was the first time I had to do so in linux after almost a decade of using it, save for a hiccup with my first gentoo kernel).
The system usually freezes if there are two or more sound streams, but that is not always the case. The best way to get the system to crash is by playing something in audacious or rhythmbox while seeking through a video in mplayer or vlc or having flash content appear in firefox (I am using adobe's latest 64-bit flash plug-in and have been using it without any problems -though on other systems- since F10). Also most but not all the times the system is going to hang, there are a few skips in audacious every ~10-30 minutes. I've been getting the lock-ups with every kernel released so far.
My system logs don't contain any useful info after each hang; there are however certain problems mentioned in syslog which I thought they could be relevant, but they always appear whether the system works fine or not, namely the following:
Code:
I used to get a lot more of these with previous kernels:

This one appeared every now and then until Dec 25:

And this one is always there:

Finally, at every boot I get this from abrtd, but it doesn't seem to be related:
Code:
Yesterday, I devoted the entire day to hunting down the culprit, but I couldn't get the system to hang; I had rhytmbox, audacious, totem, vlc, mplayer and vlc all playing music and videos simultaneously from local disks, network shares and through upnp, I got myself a facebook account in order to play that zynga poker thing, I upgraded alsa-lib to 1.0.22 from updates-testing, rebooted countless times, but the system didn't hang nor did any of the above messages disappear. Today as I was browsing through some web pages, one of which had an interactive flash ad, while listening to music and the system froze again.
I have been having this problem for about two weeks now where Debian's network and internet connection randomly fails. It works perfectly fine and hosts all the services I need for a while, and then without warning all network connectivity fails. I can't ping any other network device. Regardless of how much I try to fix it, the only thing that works is restarting the computer. First, the server went 7 days without a problem; then 5 days; now it lasted 2 days. Judging from my Teamspeak server logs, it crashed today at 12:31. I grep'd through my log files and found this information:
I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.
I have a new IBM x3650 that I am trying to get installed and running. However, it seems to experience random segfaulting. The system has ECC RAM and I have taken a look at the EDAC reports from the kernel, but as far as I can tell there is no error.This is a critical system I need to bring up, so I can't have it act flaky like this. Software is up to date. [URL]

I've installed fedora 11 (GNOME) on my laptop. It sometimes reboot itself. The screen goes black and reboots(sometimes just turn off!) Palimpsest Disk Utility reports HDD bad sector but when I run memtest, everything looks fine. Windows xp does not have this kind of problem before I use fedora
