OpenSUSE Wireless :: WiFi Connection Dropping At Irregular Intervals
Jan 5, 2010
In summary, I am using openSUSE 11.2 x64 on an Acer laptop with a wireless AR928X card. I can connect to my WEP-secured network when I boot up. After some time (it might be minutes, it might be hours), I am prompted for my WEP password again. This never works, despite being the one which gets me on-line at start-up!. The only solution is a reboot. The problem is intermittent and doesn't seem to depend on my on-line activity. I have tried the following with the same result:
Traditional using IFUP
Enabling / disabling IPv6 support
I tried installing the compat-wireless package through YaST and then managed to get no internet connection at all. Went back to KNetworkManager and things "worked" again until I was prompted for the WEP code. I have openSUSE 11.2 x64 working on my office laptop without problem and can connect to my home network without any problem. My issues are with my personal laptop. I have reached the stage of booting into Windows 7 as my default option so that I can access the internet reliably. What I can do to diagnose and repair the problem - could it be that the card is going into powersave mode? If so, how do I stop that happening? I'd prefer to be on openSUSE but need to be able to rely on the internet.
I'm using an Acer Aspire 3000 since Opensuse 9.3. Wireless connection was fine with ndiswrapper. I upgraded to 10.0 and wireless was perfect with the broadcom firmware. Now I just installed openSUSE 11.3 and my wireless connection became a nightmare: connection drops multiple times in a day and network manager remains stuck in "Interface Configuration". Sometimes I'm asked for the wpa password but Network Manager is unable to reconnect until I disable and re-enable my wlan card using the killswitch. The access point is the same zyxel b+g I own since 5 years! I just bought a new eeepc and I installed on it openSUSE 11.3 too. The network connection behaves the same!! The Network Manager says "Interface configuration" and I must switch the wireless off and on to have the network back. I made a radio scan and I'm using a channel on my own. I also tried to disable dhcp without success.
Toshiba A215 laptop Driver is rtl8187 I really need to make the connection constant and non-dropping. I've had opensuse 11.2 since march 7 2010, figured out most of it by lurking and reading threads didn't want to make threads but I really don't know what to do to make this connection stay on. I am posting Terminal commands from when I am both on and offline.
How I attempted to fix this issue myself: I downloaded wireshark, wicd,knetworkmanager. Tried running all of them nothing worked. I went into Yast and switched off networkmanager and went traditional still nothing. Tried adding opendns to traditional. nothing. Went back to NM would get online then after an unknown time I'd lose connection even though NM said i was still connected. Offline running terminal commands from what I read on here in other threads and stickies

Here's the situation: I've got an eee pc 901 running Ubuntu 9.10 netbook remix. I'm using it to connect to a WPA-encrypted wireless network on a WRT54GL running dd-wrt. It mostly connects and works ok, but sometimes it just stops working for no apparent reason (the netbook still shows itself as connected), but you can't get anywhere until you manually disconnect and reconnect. Other times, it will drop the connection, and then quickly reconnect (or sometimes not). Obviously, this behavior is pretty irritating. At first I thought the problem was with the router, but I checked the logs there and they all seem fine, and other computers on the same router don't have this problem. Looking at "dmesg | tail" on my netbook, I see a lot of instances of the following error, which I'm thinking is probably the problem:
I searched for that error message and I found this Ubuntu bug report: [URL] that describes symptoms that match mine. In that report, a poster mentions that he compiled and installed a new version of the wireless driver from the Ralink website, and it fixed his problem. Do you think installing a new driver would be good? Or has that updated driver already been added to the kernel since that bug report was filed? I've never compiled a kernel module before.
One other thing, I also see repeated instances of these lines (or similar ones) in dmesg, which look like they could be related.

I'm trying to use these cookie cutter rules that I found. But every time I use them, after a few seconds my wifi connection goes dead. The exception was the first time I used then. Which lasted me a couple of minutes.
By dead I mean I can no longer open a webpage or ping google.

As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

Just installed kubuntu 10.10 on a dual boot with winxp on my asus r101 netbook. wireless connects perfectly, but after roughly 30 seconds, i cant access any address or ping an url or ip. however network manager says im still connected. so i click on network manager, and click on the wireless connection, it then reconnects in a couple of seconds, and all is good again. i carry on browsing, and 30 seconds later the same happens again!!! my wireless signal is fairly week, however connection works everytime and in xp this is not an issue.
After entering the command I have lost all ability to even use my wireless ability even if it was for 5 minutes. Now I am using a different kernel, internet still drops every 5 minutes, but would love to get my internet up and running again.
I am having an issue with my wireless connection dropping about every 2 minutes (web pages timing out), then working for a couple of minutes then dropping again. The connection icon in the task bar says I'm still connected at about 70%.I have a dual boot system and the wireless works fine in opensuse but not in Ubuntu 10.10 I have an Asus G50vt-X5 laptop but I am not sure about the wireless chipset.
I have installed Suse 11.4 recently and I'm trying to run the wireless connection and doesn't works. Details: card: pro/wireless 2200BG Calexico2 driver installed (as console said) kernel driver:ipw2200 hwinfo:
I have tried to connect by traditional method with YAST, just recognized one network call "Hotel Riga 228", but doesn't connect. Also I have tried to connect with Network Manager but this application doesn't recognize ANY w. network.
I have a dual boot system : Windows XP SP3 and openSUSE 11.4 64 bits, GRUB for boot loader.Having had problems with my NVidia driver (computer hanging all the time), I reïnstalled openSUSE 11.4 from DVD.Since then : no more wireless internet-access, which functioned very well before.
Code: /usr/sbin/iwlist scan lo Interface doesn't support scanning.
as the titles states my wireless is dropping out but the networks manager is still saying i have a connection. the only way i have been able to be on the network every minute or so i have to manauly disconnect and reconnect to my wifi. under my windows 7 and vista installs the wireless card works fine now my card is a dlink dwa-547 and it uses the arthores chipset, it is encprtyed wifi, wpa2 aes on a n/g based network
Code: Network controller: Intel Corporation Wireless WiFi Link 5300 I have Ubuntu 10.04 32bit installed:
Code: Linux dani-laptop 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC 2010 i686 GNU/Linux
It has been working fine since I installed 10.04 but recently (end of last week I think) it stared dropping the wireless connection very often. So it will disconnect and reconnect, but I can't seem to find a pattern, sometimes it goes for hours without an issue and sometimes it does it several times in a row. Below is an extract of syslogs from when this happens. But not sure if what I need is there... the only weird thing I can see is:
Code: Oct 27 18:58:32 username-laptop wpa_supplicant: Trying to associate with 00:1e:be:a6:c0:0f (SSID='accessp' freq=5280 MHz) Oct 27 18:58:32 username-laptop NetworkManager: <info> (wlan0): supplicant connection state: completed -> associating Oct 27 18:58:32 username-laptop kernel: [123835.372217] wlan0: deauthenticating from 00:1e:7a:6f:d9:90 by local choice (reason=3) .....

Using Wicd and it keeps dropping out or telling me "bad password" when the password is in fact correct. I even know it works because the first couple of times it worked, but the connection wasn't sustained for more than a few seconds each time. My reasoning is my wireless is functional in Ubuntu, there's no reason it shouldn't be in Debian. Wireless network card is ASUS PCE-N13. Ralink driver is installed. WPA-supplicant is installed. Gnome Network Manager is also present, though I've heard that it doesn't support my particular situation.
I have two laptops. First one is connected to my ISP via Ethernet connection. At the same time it serves as a wireless router for the second laptop (ad-hoc connection). Multicast routing is managed by igmpproxy. Everything works fine, except that multicast traffic rate on the second computer is very low (1 MBit/s), its too slow for watching television.
After some searching I found that this multicast rate is always minimal one for certain type of WiFi connection (802.11bg in my case) https://lists.ath9k.org/pipermail/at...il/003393.html. For some WiFi kernel modules its possible to set multicast rate by setting appropriate module options. But its not the case with ath9k.
Recently I updated my openSUSE 11.2 and I'm not too sure what all were the recent updates but I suspect networkmanager also got updated. After I restarted my machine, my laptop fails to connect to the wireless access point. I tried both in gnome as well as KDE but the same error. This is the log I found in my /var/log/NetworkManager which I believe should give some pointers.
No improvement since I first reported this problem, I am hoping somebody can now advise. Using openSUSE11.3 Linux 18.104.22.168-0.5-default i686 with kde 4.4.4 release 3.Problem is the wait of sometimes over 2 minutes before the wifi connection is available.Two questions:- 1. Why does it take so long? Longer by far than it to be with previous openSUSE releases. Much longer than with that other OS!!!2. How do I remove the wallet process. Not needed in present environment so I would like direct connection without having to open wallet. I didn't set this up, it just happened after I had upgraded to 11.3 and I need to know how to disable it to save time.
I have a Dell Inspiron 6000 laptop running Fedora 12. Recently my wireless connection has begun dropping every few hours and not reconnecting. After trying for about 30-45 seconds, the WPA password prompt comes up but still doesn't connect.
Fedora release 12 (Constantine) Kernel Linux 22.214.171.124-67.fc12.i686 GNOME 2.28.2 Memory: 2.0 GB Processor: Intel Pentium R 1.60 GHz
Sorry if this has already been solved;answered anywhere else - I tried looking it up but to no avail. The problem persists & the hints I found around the forum did not provide a solution to the case, neither other net solutions i looked up I run Winblows at the lab and sometimes take my Ubuntu PC with me. There is an open Wireless network where they set MAC permission, and there's no pwd to access. It so should be fairly easy to change m MAC and access it, right! No. I run ifconfig and macchange, successfully change my MAC addr BUT the connection drops! Then if I change it back (MAC to my original address) it goes back online. And yes, I shut down the service -- "ifconfig wlan0 down" and then up..WHAT ON EARTH am I doing wrong??? No webpages touch this 'trouble-frigging-shooting instance!
using Hardy Heron on a old Thinkpad T41.This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time. fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..

I have recently upgraded to 11.4 and also had to renew an AP (HP ProCurve 10ag). This was several years old but replaced an identical model which had been working well until recently. I thought it would be appropriate to flash newer firmware as the device four releases behind the times. The access point serves partner's XP laptop and my openSUSE 11.4 laptop and after flashing the firmware both machines would make a connection and then break and remake, to the extent that the openSUSE machine became unusable. I thought it was an encryption problem and spent hours changing the AP and Client setups to no avail
After reading a thread here I checked out dmesg and this is what I found:- [78.639247] wlan0: authenticate with 00:1d:b3:4b:ae:14 (try 1) [78.640804] wlan0: authenticated [78.642507] wlan0: associate with 00:1d:b3:4b:ae:14 (try 1) [78.651195] wlan0: RX AssocResp from 00:1d:b3:4b:ae:14 (capab=0x411 status=0 aid=1) [78.651200] wlan0: associated [78.652222] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [78.652283] cfg80211: Calling CRDA for country: DE [78.674378] cfg80211: Regulatory domain changed to country: DE ..... This went on and on.
I recently upgraded a 11.0 installation running on Xen Server to 11.3. I am experiencing frequent network disconnections now. The ip address and default gateway is assigned statically. However, the system seems to ignore the default gateway after a while. Then after several minutes it seems like it comes back.

Can't change the Plasma-Themes in System-Settings/Desktop-Theme Detail any more!Changed the user,same behaviour ("Apply"-button not highlighted after selecting a theme)!And more confusing,in the System-Settings/Appearence/Style/Workspace setting,there I can changethe Plasma-Themes !Downloaded a Plasma-Theme before from Kde-Look.org,that seems not to work,deleted it,but no changing.
Using an old (5 year) laptop with XP loaded I installed wubi to save altering partitions etc. It all downloaded fine and connected to the internet by wire. I set up the wireless connection using WPA but could not connect. The wirelsss card does see my network and others. After lurking around the forum and trying various things I found that I could connect without encryption. The more I read the more I became confused. Anyway what I could glean about my Wireless Card it is a Intersil Prism2 mini usb adapter - but also shows up as an Acer ?? Warplink 802.11.
Using lshw I found this reference to wireless
I became even more confused and got a bit lost using the various codes in the terminal and looking up things about drivers etc but would like to persist.
wicd keeps dropping my wifi connection most of the time I can just tell wicd to reconnect the connection never stays up for more than 10 minuets with out doing other times it looks like it connected when it didn't other times it times out when obtaining the ip address in these 2 cases I have to run "etc/rc.d/rc.wicd restart then tell it to connect sometimes posting on forums requires me to copy my text hit submit hope the connection is still up maybe restart wicd reconnect.is there a bug in wicd or python ?
Our school has a small 3-computer lab in the preschool department where the kids come in and simply use Firefox to access some educational websites. Due to logistics in the building they're in we had to go with a wireless solution in the following setup:
- Apple Airport Extreme WAP - 3 HP DX2200 desktops running Ubuntu 10.10 - 3 Trendnet TEW-664UB USB wifi chips
All was running great until we got the computers installed on site and now they are constantly dropping the wifi connection if they are even able to connect at all (which is highly hit or miss).
10.10 picked up the USB wifi card as soon as we plugged them in and showed the available networks, but actually obtaining and keeping connections is a nightmare at the point. The computers are in very close proximity to each other (only about 2-3 feet between computers) and the WAP is in the next room (other computers and mobile devices are able to connect to the WAP with full signal from the same room/location). Thats about all the detail I have off the top of my head, could this be an interference issue with the wifi cards or does this sound like an Ubunutu issue? Again we have had multiple other devices in that room all able to connect seamlessly.
I've got a Belkin F5D8055 v1 wifi usb adapter. I use the rt2800usb driver for it. Strangely it uses only 54 Mbit/s instead of 300 Mbit/s. I thought it was ok, since I use the wifi only for accessing the internet. However, the network manager keeps dropping the signal, and I can't understand why. I'm close enough to the router.
