OpenSUSE Wireless :: 11.1 - WiFi Randomly Disconnects / Reconnect Automatically

Sep 6, 2010

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 behaviour 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.

OpenSUSE Hardware :: 11.4 - Wifi Won't Reconnect Automatically

Mar 11, 2011

I upgraded my openSUSE to 11.4 and wifi was still working out of the box.

However now when I turn the wifi off using the hardware button and than back on, or when I wake up from hibernate, (k)networkmanager won't recognize the wifi device... I actually have to run /etc/init.d/network restart to reconnect to network. The problem is that it worked in 11.3... why not in 11.4? Now every time I hibernate my laptop I had to manually restart network. In 11.3 it was automatic...

OpenSUSE Wireless :: Auto-reconnect Wifi When It Is Down?

Apr 10, 2010

I have my openSUSE 11.2 connected to router by wifi. I want frequently to access it from my LAN or even Internet, but even so frequent the connection is lost for some reason.

When I am at the box, I can easily do a ifdown/ifup and it will reconnect, but that is a pain when I am not local.

is there some way or maybe a script to check the connection so now and then and if not online then re-connects it automatic ?

Ubuntu :: WiFi Randomly Disconnects After 11.04 Upgrade

May 5, 2011

I just upgraded from 10.10 to 11.04 but other than that the most annoying thing I've found is that my wifi will randomly disconnect from the it will say its still connected but pages wont load and all my torrents just stop, and then I have to manually disconnect from the network and then reconnect and it works for about a min and then happens again. I couldn't even get enough internet to post this from my laptop so I had to post this at school from a windows. Idk whats going on but it sucks because I cant really use the comp without the internet..

I recently set up a new desktop with openSUSE 11.3 64-bit GNOME, and I'm having some trouble getting the wireless to behave.I'm using a D-Link wireless USB, which uses a Ralink chipset. According to dmesg, the firmware is rt2870.bin.I can connect to the network, but it automatically disconnects after a while.

Ubuntu :: Wireless Randomly Drops Connection And Refuses To Reconnect?

Mar 23, 2010

my wireless will connect to a well known connection but will sometimes drop the connection then tries to reconnect. Sometimes it will reconnect w/o a problem but most times it will fail and when it fails it will refuse to even recognize that same wireless connection.

If by a small chance it does recognize the network then when you click on it, it will ask you again for the password, which is already saved onto the computer. After entering the password it will try to reconnect, then fail.

Only solution is to reboot.

I was wondering if there was an easy temporary fix of just reloading the software that controls the wireless.Such as, my audio doesn't work when I boot. I need to reload the ALSA driver using sudo /sbin/alsa force-reload

Is there something specific to the wireless that I can force-reload and it will start working w/o having me reboot my PC?

Ubuntu Networking :: Lucid Wireless Randomly Disconnects

Jun 25, 2010

After upgrade to Lucid I have experienced intermittent wireless disruptions. The wireless just cuts out and reconnects.And I was hoping to continue or follow up on the same thread however with the released version.I tried replacing network manager with wicd and I tried the other driver options both without success.I'm currently using the Broadcom B43 driver, when I tried the Broadcom STA driver wireless would not work. I use the 64 bit OS, and this problem did not appear prior to the upgrade.

Ubuntu Networking :: Wireless Randomly Disconnects - Only Works Again After Reboot

Jul 3, 2010

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.

I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.

OpenSUSE Hardware :: USB Randomly Disconnects

Oct 8, 2010

I'm not sure if this started with the or update, but one of those.At random intervals the USB subsystem disconnects. When that happens the monitor screen goes black (no input signal) and then returns 1 - 2 seconds later. This was happening every once every 1 - 2 days; today the count is 10 times. It's gotten really annoying.There is a topic about USB mouse and keyboard becoming unavailable due to recent kernel updates. That is not the issue here; I have tried disabling USB auto-suspend with no observable change in behavior.Or could it be that I have a defective mouse?

Ubuntu Networking :: Intermittent Internet On Wireless/wifi - 10.10 Disconnects Repeatedly?

Dec 31, 2010

I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.

I've tried :-

-disabling ipv6..... first in Firefox, then in Kernel also
-Setting DNS.....System> Preferences> Network Connections
-setting static Ip

The system still gives trouble.

My system is Asus UL20A.
Wireless:-Atheros AR9285

Ubuntu Networking :: Server Randomly Times Out/Hangs/Disconnects

Jul 12, 2011

I have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.

If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.

Debian Configuration :: The Network Doesn't Automatically Reconnect

Dec 9, 2010

I'm running squeeze testing. I have noticed an issue with the way NetworkManager acts when the wireless connection is dropped. I believe it should automatically reconnect but it immediately puts up a dialog requesting me to enter the wifi password. This dialog stays indefinitely until I intervene and click "OK" (the password from the previous successful connection is still there). I would think that something as basic as wireless networking should not require 24 hour human interaction to stay connected. I have considered a cron job checking the network status and restarting it if necessary, but there is a configuration change or something else I can do to resolve this.

Ubuntu Networking :: WICD Not Automatically Reconnect After Suspend Or Hibernate

Ubuntu :: Removing KDE Secrets On Wifi Reconnect?

Nov 18, 2010

I installed Kubuntu on my PC I want to use remotely, without having keyboard, mouse nor monitor connected to it. So I want it to reconnect automatically if it loses the connection.

I upgraded to newest version of kubuntu, so I have KDE4 and newest network manager app. I have password set to my KDE wallet, so I enter it on boot and the app connects.

But then if kubuntu loses connection and tries to recconect a window appears with "secrets", where I have network connection screen, the password for my wireless network is already in the necessary field and all I have to do is press OK.

Well, I don't want that window to appear. The app already remembers my password, it detects it has to reconnect, but it makes me confirm the password is correct? I want to make it just connect, without my input. But I have no idea where to look.

I've checked the options in network manager, but nothing on that. Then I don't want to change the app if I won't have to, linux tends to be pretty touchy with my network card and I'm afraid it could stop detecting it or something...

Edit: The window appeared again so now I can put full title of it: "Secrets for [NetworkName] - KDE Daemon". Under it I can choose security type for [NetworkName], there is field for password, with the password already inserted and "show password" field under it. Oh, and OK button.

Edit 2: Obviously KDE wallet has "always allow" option for KNetworkManager.

Networking :: Wifi Won't Reconnect After Standby Or Hibernate

May 3, 2010

I am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address. And if I try to change networks without hibernating I get the same problem. Also, I notice that the network name is stagnant. I connect to multiple wifi networks a day because of school. When I leave my "home" network and connect to my "school" network WICD still says "Homebtaining IP address" even thought it should say "schoolbtaining IP address." My thoughts are that it isn't releasing the network properly and when its trying to connect it can't because it still thinks it's connected. The only solution I have found is to restart my laptop every time I want to connect to a new network, or shut down every time I am done using my laptop, which is a major inconvenience.

Here is what I am using:

HP tx2000
Broadcom BCM4322
Ubuntu 10.04
WICD 1.7.0

OpenSUSE Network :: Nfs No Longer Starting Automatically With Wifi?

Jul 27, 2010

Running openSuse 11.2-64 on a DualCore / 2Gb machine.I have 3 nfs shares described in my /etc/fstabAll three were mounted at boot time when I was connecting to the network through the wired interface (eth0).I need to use the wireless interface, and even if that interface is up and running well (I use ifup), the nfs client doesn't start... if just after boot I do a mount -a or simply a nfs start, everything comes up and runs well.This machine will not be used by myself, and the users cannot just jump into a command line and type nfs start or even mount -a (they would need su privileges...)I have disabled the eth0, killed the eth0 config (with yast) edited /etc/sysconfig/nfs and setted the NFS_START_SERVICE to yes to force the gssd and idmapd to always start even if there was no nfs entry in fstab, but nothing changed.

OpenSUSE Wireless :: Intel 3945abg Wireless Network Card Cannot Connect To Router Automatically

I clicked "Network Settings", and I found that the ip address was wrong, which is "", and netmask field is empty, so I modifed the configuration file located in /etc/sysconfig/network, named ifcfg-wlan0, added one line(NETMASK= ''), saved it and reboot the system. After rebooting the system, I still found the ip address is wrong and netmask field is empty, so I have to use ifup command to activate my card manually every time the system starts.

Ubuntu Networking :: Intel Corp. Wifi Link 5300/Karmic 64b/ThinkPad W700: OS Restart 2 Reconnect

Oct 7, 2010

I have an IBM ThinkPad W700 running 64 bit Ubuntu 9.10 Karmic Koala. At the office I normally connect it to the Ethernet since it's never connected very reliably to the wifi there (drops out 2 or 3 times per day, usually at the worst possible time, of course), but it always worked just fine with Netgear WGR614v5 at home... until a week or two ago.

I used to be able to come home, take the laptop out of suspend mode, and it would connect to the wifi. Occasionally there'd be some hitch and I'd have to restart the network manager (sudo /etc/init.d/network-manager restart) but this was only sometimes, and when I did, it'd always work. But now, when I get home from work, I need to restart the entire system to get it to connect properly again. Without restarting the whole system, it either doesn't scan for wifi networks, it doesn't find any wifi networks, it keeps stuffing up my wifi password, or it connects and gets 0% signal.

Presumably, some driver was updated recently and it doesn't work so well. What's the easiest way to find out what drivers have been updated lately, and revert to a previous version? And what else can I try restarting so I don't have to restart the entire system? I've tried /etc/init.d/network-manager restart, /etc/init.d/networking restart, /etc/init.d/network-interface restart, and restart network-manager. I've also tried turning the wireless switch at the front of the laptop off and on, many times.

$ lspci -nn
03:00.0 Network controller [0280]: Intel Corporation Wireless Wifi Link 5300 [8086:4236]
$ ifconfig wlan0


The info above is when I've taken my laptop out of suspend mode and it won't connect to the network. lsmod doesn't say anything about wifi nor wireless; iwlist does see my network, which my older Januty laptop is connected to without drama.
