Fedora Networking :: F13 KDE Intel 4965AGN Disconnects Every 10 Minutes
May 30, 2010
I have recently installed Fedora 13 on my laptop, an Acer Aspire One D150. The laptop has an Intel 4965agn wifi card which worked flawlessly under Fedora 12. Now however it keeps disconnecting every 10 minutes, even if I browse the web. On top of this, it also becomes very hot, so hot that you can feel it through the plastic case.
Have been running Fed 11 on this laptop (dual booting with windows) for some time with no issue's. Removed 11 and installed 13. I now cannot get my wireless adaptor to pick up. Drivers are loaded and sees the card in lspci, here is some log outs I have made:-
I just installed Fedora 15 yesterday and can't get wi-fi to work. When I click 'on' on the Wireless label, it goes back to 'off' immediately. When I open the Network Settings menu and disable Airplane mode, the Wireless connection goes on and then off immediately. I took a look at /var/log/messages and it shows this:
With Fedora 11, I got NetworkManager, and it never worked right.. Right now, the nm-applet crashes regularly, no message nothing, just disappears from the panel. I wrote a two-liner to run it in an infinite loop. But my wifi also disconnects every 10 minutes. It's like clockwork, it just disconnects. I see things about "error 38" in the logs. I tried downgrading, upgrading, nothing helped.
I'm using a notebook with Intel 4965AGN and connecting to a Linksys WRT320N router. I can connect most of the time but after a while (sometimes a few minutes, sometimes a few hours) I lose connection. The notification icon would not change. I would only find out when I browse or click on a link and it would just get stuck at "Looking for <url>..." My wife's notebook would still be connected to the router even after mine has mysteriously disconnected. But she uses another os.
I'm trying to set up ubuntu on my netbook, the brand and make is obscure, essentially, this is a no-name brandless build from china, but a pretty decent lappy. Atom N270 Intel 945GSE based. initially it was equipped with a 3DSP wifi/bluetooth mPCIe combo card, which is proprietary and didn't work on ubuntu (didn't even show up as a device), so I got an intel 4965agn based on compatibility list somewhere in the wiki.
The problem I have is that I see networks, but can't connect at home or at work or anywhere, it just hangs in the connecting status and then throws the authentication popup at me again (pw is all correct). I tried looking around at similar problems, some have wpa_supplicant related issues, but doesn't seem to be the same as mine.
I tried creating an unsecured network using my macbook's airport, and same thing happened with ubuntu... hangs in connecting status then drops, so it doesn't seem to be WPA. I don't have the device on me to do all the iflist iwlist checks for you, but if you could give me some clues, I'll post back when I get home.
I have lenovo thinkpad, T61 with Intel 4965AGN wireless card. It is a N card, it works under N mode in windwos, but not in Ubuntu (10.10). I installed ndiswrapper and got the windows xp drivers for this card. the issue is that i got an error when installing the drivers and since then I cannot use wireless.
The error i got is: Code: Module could not be loaded. Error was: FATAL: Could not read '/lib/modules/2.6.35-24-generic/kernel/ubuntu/ndiswrapper/ndiswrapper.ko': No such file or director I unistalled the driver, but now under network connections no wireless connections appear, nothing. I cannot use wirless anymore.
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.

The symptom is that NetworkManager repeatedly ask for password to connect to my AP.My AP is secured with WPA-PKI. The problem even happens with Fedora 11 live cd if I'm not quickly configure wireless connection using NetworkManager right after Fedora completes booting up. It means if I promptly configure wireless connection, i'm still able to access Internet. Same thing happens for the first boot of Fedora from hdd. For the second boot or when I dont quickly configure wireless connection when system finished booting up, NetworkManger repeatedly asks for password for AP.
I did try several approaches posted in this forum but problem still persisted. Some of approaches I tried are:
i just installed open suse 11.3 after using linux mint 7(based on ubuntu 9.04).i am currently using two internet connections at home, the first is a vodafone mobile modem, which is workind excellent, and the other is a LAN network, that on windows uses a *.exe program to run. i managed to make all the IP, NETMASK, DNS settings and the internet connected, but without the .exe program it just disconnects after 10 minutes.this is the same thing that happens with the connections on windows if i start the computer and not run the "net.exe" program, but if that program is running the internet connections works just fine. i tried using wine to run net.exe, but it just gives an error message.
I have a Dell 1501 Inspiron laptop and have swapped out the broadcom network card for an intel 4965AGN so I can use n-speed with my new router.Everything works sweet except my laptop now crashes if I try to run on battery power.It boots up to the login screen, but once I enter password and login it crashes, just get grey screen and everything locks up. Everything works fine on mains ?It's not a major problem for me as I don't use the laptop "out in the wild".
After I updated to kernel-184.108.40.206-159.fc10 a couple of weeks ago, my wireless kept dropping the connection every few minutes (using an intel 3945 with the kernel iwl driver), particularly if secured with WPA. Updating to the 220.127.116.11-170.2.5.fc10 kernel currently in updates-testing has solved the problem.
This is the first one of probably many posts as I am new to Fedora having lots of questions. This one is about the openvpn client which is used by me to connect to my company network. Thanks to the Fedora FAQ it was easy for me to set up the client and establish a connection. There is just one problem every time I open a connection I am disconnected from my local Internet. I was using openvpn on my Windows XP PC before and there was no problem keeping two Network connections, the (W)LAN and the vpn tunnel. Does anyone know how to solve this? I am utilizing the latest Fedora 11 release and configured openvpn client via the Network Manager GUI.
After a new fresh-from-DVD install of Fedora 14 64-bit (over top of Fedora 12 64-bit which went over top of Fedora 10 64-bit before that) my Linksys WUSB600N adapter connects at login to my WiFi N router with WPA2 Personal.
That is great, as previously (fc10/12) I had to use the Ralink drivers per ogetbilo's thread on this forum (that thread kept me on the net for many years now). And at some point this even became a pain because sometimes the system would boot and refuse to connect to the wireless (which would hang trying to connect) and then crash to a dump screen on shutdown (bug reported). The fix was hoped to be found in upgrading to F14 and the newer kernels with working native Ralink chip support.
But I still have an issue... the connection stays up for a few minutes then drops. If I disable/re-enable wireless it (at least sometimes) re-connects. But obviously that is not workable. This is a USB adapter and I am not entirely sure that there is not some USB powersave issue going on, but I do not see anywhere to disable system USB power saving either.
I recently installed Fedora 14 on my machine. Ever since I cannot connect to the Internet at home.henever I plugin in the ethernet cable the ADSL router disconnects and all machines connected to the router lose connection to the Internet.
I'm currently on F11, and experienced problems with Network Manager. Whenever I to connect to a network, wired or wireless, it just seems to try to connect, and then after 2-3 seconds, it just reports "Disconnected"..
Then I switched to network, and both wired and wireless works. so I don't think there is any driver or hardware issue...
Does anyone have any idea of this problem? The network manager have worked on the live CD version ( before installed to HD).
I use a secure connection to reach company network from outside. There's a client application "Juniper network", which creates the secured tunnel to a company network. However, the connection never survives more than 8 seconds, when it goes disconnected with the message "Route monitor alarm". From my recent search for a solution I've found that this error is caused by a change in a route table, which violates a connection policy.
"This disconnect is typically triggered by a change in the routing table of the client machine, the change is such that the split tunnel policies defined by the administrator will be violated" - from [URL]
This is how a routing table looks before, during and after the connection attempt:
I installed Fedora 14 yesterday via the installation DVD with 3,3 GB. Everything worked fine and when I connected to my wlan and entered the WEP key I got access to the internet. But after about 5 minutes, to connection just got cut and I was again asked for the WEP passkey. But when I entered it this time, the connection failed and I was just asked again (with the same key entered, it even got it saved from last time). As you can think, this is quite annoying, since the time I have internet is not even enough to get some updates done.
Ah, and by the way: The time I have internet it just is unbelievably slow. On my Windows partation, I don't have this problem. I do have a small hint what might be the problem: When I was using Ubuntu, I always had a similar problem, but it did not even connect to my wlan once. The solution was to blacklist some driver, but since I don't know if this might be the problem on Fedora too and if the drivers are the same as on Ubuntu and since I really have no idea about the syntax of the terminal here, I was not daring to try this out.
I have fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.
I'm running Fedora 12 on an Acer Aspire One with KDE. The built-in wireless works without a problem EVERYWHERE except at work. It's a shared wireless connection using WPA/WPA2 security.I can connect but it's "hit-and-miss" if I can do anything with it. Somedays it works well for a few minutes then has a period of inactivity - then slow - randomly receives...It worked flawlessly when the computer was running Windows7 no one else has connectivity issues but I'm the only one using Linux.
Are Intel wireless cards compatible with non-intel-based laptops? In my case I wish to upgrade the current Atheros-based mini pci express wifi card with the Intel 4965agn. It is an Asus 4520 with an AMD Athlon X2 processor and nvidia nForce chipset.
I recently installed F10 x86_64 on my Lenovo T61 laptop, and while I'm quite pleased with F10, I am having a difficult time with my wireless card. I spent most of yesterday searching for a solution, but none have presented themselves. Scenario: I am trying to connect to a HIDDEN SSID with NO ENCRYPTION (work Wifi, don't ask) using network-manager and its associated applet.
Symptoms: I left-click on NetworkManager, select "Connect to Hidden Wireless Network", enter my information, NetworkManager does a few things, and finally I'm told that NetworkManager cannot connect to my network.
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69 real 9m54.886s user 0m5.536s sys 0m1.740s $ ls -l test-32000.wav -rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?
I was trying to update the drivers for my wireless card and it no longer works. I have a cisco pcmcia card that I got working to use as a backup, but I would prefer to use my internal card. The card is the Intel Pro 2200BG. Please let me know what information is needed to diagnose and correct this issue. I am relatively new to Linux (Currently using F10) and trying to learn.This is the iwconfig from my cisco card. The Intel card was working fine yesterday. but now doesn;t even show up.
[west@garfield ~]$ iwconfig lo no wireless extensions. eth1 no wireless extensions.
