Ubuntu Networking :: Connection Drops Randomly For A Split Second
Jun 5, 2010I could not find a solution to this problem anywhere. I use a ubuntu server to play (stream) mp3s and movies to other computers on my network. It works most of the time, but sometimes in the middle of a movie or a song it will drop/hiccup--saying it is "not reachable". I am not overtasking the server at all, and merely playing an mp3 that takes up less than 10% of the bandwidth, yet it drops it for a split second.
I have a WRT160N router (DD-WRT of course) with 4 clients connected (2 of which are wired). The ubuntu server is connected via ethernet and all machines have the same issue. It can't be the router because another Windows machine works just fine for streaming these files. I just can't understand how it can lose connection for a second or so. It may just be the file-system or some service that is hiccuping, but I have no idea...

Mar 23, 2010my 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 :: Wifi Connection Drops On Laptop?
May 1, 2010I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

Ubuntu Networking :: 10.04 - No WiFi Connection (Light Randomly Flickers)
Dec 8, 2010I have installed XUbuntu 10.04 but cannot connect to WiFi. Here is what I know so far:
Hardware and Software configuration:
Compaq Presario 2100US
XUbuntu 10.04 (installed Dec. 2010 from Live CD dated Oct. 2010)
Kernel 2.6.32-21-generic
Gnome 2.30
RAM Memory: 938.7 MiB
Processor: Celeron
Disk Space Avail 23.2 GiB
Wireless Card: MSI Wireless 11G CardBus CB54G2
*MSI Driver rt2500pci located in system (see below)
No wifi 'on' 'off' hardware switch on machine
Prior to the install of Xunbuntu 10.04 (Lucid Lynx) the machine carried MSXP. The wireless card came with the machine. The machine used a cable connection by previous owner. Connection's been working fine in Ubuntu Jaunty Jackelope and Puppy Linux. Wireless card appears to be functioning. The system scans for the network, shows that connection is established by both icon in tray and message saying that a connection is made. The card shows both green lights active. The light that indicates a connection is on and randomly flickers. Tested Firefox for connection. Firefox is not receiving anything from the system. I have got the network manager functioning enough to say that I have a 'connection' but still cannot connect to server.
Network Connections
wireless: linksys - mode ad hoc - MTU auto
wireless: security - none (I borrow from a neighbor's wifi)
IPv4: auto(DHCP)
IPv6: Ignore
*Driver rt2500pci located in /sys/module/rt2500pci/drivers/
(There is a 'config' file in this directory)
Help menu in 10.04 is listed as help menu for 9.04 so don't know if applicable to 10.04 debugging. When 'troubleshooting' wireless connections, I did a *sudo lshw -C network* command on terminal. The results *do not* show 'Claimed, Unclaimed, Enabled or Disabled as help menu indicates. The line that would show that information (*-network) doesn't have 'Claimed, Unclaimed, Enabled or Disabled'. I can send image of this query. I have tried two other wifi cards with similar results, no connection.
Ubuntu Networking :: Wireless Network Connection Disconnect-reconnects Every 5 Min
Jul 31, 2010I recently installed Ubuntu 10.04 on my Acer TravelMate 3270 notebook (with Windows 7 dual boot) for everyday use. All is great except i started to notice my Wireless Network get disconnected and then reconnects every 5 minutes or so. Also the NetworkManager Applet 0.8 keep annoying me with the notifications that its disconnected and then reconnected.
I do not have this issue while using Windows 7 (in the same area). Can this be fixed. As i really want to move my day to day computing need to Ubuntu.
Fedora :: Network Connectivity Drops Out Randomly?
Jan 21, 2010Installed Fedora 12 recently.
For some reason, my network connectivity drops out randomly. This has happened between 5 minutes to 1 hour of booting and logging into the machine.
When the internet does work, its great, and super fast !
When it drops out, Internet stops working, cannot ping to external site and I cannot ping my router 10.1.1.1
I have onboard realtek network ports on my motherboard.
Ubuntu Multimedia :: VLC / Phonon Randomly Drops Audio Stream
May 24, 2011I have an Asus EEPC that I use in my classroom whenever I want to show a movie. I normally keep all of my educational videos as ISOs, and then simply move one over to the netbook when needed. I normally use VLC for playback. With the latest upgrade, however, I'm having a few difficulties. No matter what DVD I choose to show with VLC, the audio stream will randomly drop every 10 minutes or so whenever I am using KDE as my desktop environment. In order to re-enable the audio stream, I have to either completely stop playback OR reconfigure the audio output in VLC.
(It does not matter if I change it right back to what it was, I will get audio for another 10 minutes or so). I've also noticed that if I pause playback, sometimes the audio will not re-enable when unpaused. Strangely, however, I do not have this behavior at all when I'm using Gnome as the desktop environment. I get seamless audiovisual playback and never have to fiddle with the audio. Is this a documented problem in Phonon somewhere? How I might better backtrace what's going on?
OpenSUSE Hardware :: Sound Card Randomly Drops From Configuration?
Mar 25, 2011Since I started to use Suse 11.3, I've been having problems with my sound card. It starts normally and I can use it without further problems, until it randomly stops working. I don't know what causes it to stop working, it just does. Then, if I go to YaST>Hardware>Sound (it shows I have a 82801G (ICH7 Family) High Definition Audio Controller), press edit then reset, it works again!
I've been doing this for like 4 months, but I'm growing tired of doing it and not being able to just sit back and enjoy music on the amarok. I don't know what should I report, so that's why I only say the sound card identification.

View 14 Replies View RelatedUbuntu Networking :: Asus Eee PC 1005HA Drops 50% Of Incoming Packets Over Wifi?
Oct 30, 2010Pinging out from my netbook (over wifi, to any host) gets ~0% packet loss. Pinging into it (from any host) gets about 50% packet loss.
The router is a Dlink-DIR615 (rev d, running DD-WRT v24-sp2) but all other hosts on it ping eachother fine. I've tried changing routing, disabling IPv6, using older kernels and using wicd, all with no luck. The wireless connections is at 100% most of the time. This could be a new problem with Maverick, but I may not have noticed it before. I believe this is causing web browsing to be really slow and causing SSH timeouts.
I haven't tried madwifi drivers or nsidwrapper yet.
Edit: just booted into Windows and it has the same problem. Could it be a hardware issue? Also tried with a static IP, with no change.
Strangely, a normal ping gets 50% packet loss, but ping -A gets < 1% loss.
Edit 2: no packet loss at all on eth0.

Ubuntu Networking :: Wifi Speed Drops Periodically And Will Not Increase Without Reconnecting?
Jan 25, 2011after maybe half an hour, the wireless download rate drops to about 110ks (and runs happily at up to 20x this until then). At that point, it will never pick back up above that rate unless i disconnect and reconnect. Once the problem occurs once, its like to reoccur about every 5 to 10 minutes until the machine has rebooted.

View 2 Replies View RelatedUbuntu Networking :: Server 9.10 Lan Connection Drops ?
Jan 23, 2010I got a new low power file server (Atom 330 with ion), but didn't enjoy it since.
I installed Ubuntu server 9.10 64bit.
I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan).
Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut.
I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem.
I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down.
When this drop occurs, I have to wait 2 minutes until I can ssh back into the server.
I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes.

Ubuntu Networking :: Wired Connection: WAN Drops But LAN OK
Aug 17, 2010I've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.

The wireless network still shows as being connected but I get an error on the windows machine if I try to connect. I've Googled this and it appears to be a Windows problem. I know this is a ubuntu forum but thought I'd ask for any info. I believe that this is also what is giving me shared printer issues as well.

Dec 30, 2010I have a server running Ubuntu 10.04. I use it for mysql as well as samba file sharing across 10 computers. It had been working out great. I only ever needed to restart after I would install updates and to sort of thing. Starting this week however, it has started kicking all the computers off of both mysql and the samba shares every few minutes. It is very strange. The mysql connection can be restored just by closing the database and reopening it. The file shares are only a problem if you try to access them though a program other than your file browser (e.g. save a file you are working on in word to the server). The server never shuts down and all services can be reconnected immediately. It is very strange. I do believe that the server installed some automatic updates at the beginning of this week when this all started happening. I am not sure if one of the updates is causing the server to do this or not.

Jun 13, 2011Having struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!
