Ubuntu Networking :: Wireless Network Connection Disconnect-reconnects Every 5 Min
Jul 31, 2010
I 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.
I have a cisco linksys wireless adapter (WUSB600n) which, most of the time, great when booting up. But mostly after some time (1min- 1hr.) it disconnects. When checking the status I can see some of the networks around me, including mine. But selecting it doesn't do anything. I searched the forums and tried:
sudo dhclient and sudo /etc/init.d/networking restart
But still no connection; the only thing that helps is rebooting.
Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.
I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.
For the past week or so, I've had my wireless connection disconnect and reconnect at seemingly random intervals. It can be anywhere from every minute to every hour, whether I'm using the network or not. I don't recall installing anything that could affect this. I'm fairly certain this isn't a hardware issue, since I haven't had any problems when using my Windows partition. I'm using a D-Link USB adapter (DWA-171).
After the last system update (few days ago) the wireless box disconnects and reconnects continuously (every 60-90 secs). This is the pertinent /var/log/messages when it disconnects: Code: Jan 11 16:16:24 ibm kernel: [ 8073.320442] -->RTUSBVenderReset Jan 11 16:16:24 ibm kernel: [ 8073.321453] <--RTUSBVenderReset Jan 11 16:16:26 ibm kernel: [ 8075.624596] Key1Str is Invalid key length(0) or Type(0) Jan 11 16:16:26 ibm kernel: [ 8075.624632] Key2Str is Invalid key length(0) or Type(0) Jan 11 16:16:26 ibm kernel: [ 8075.624668] Key3Str is Invalid key length(0) or Type(0) Jan 11 16:16:26 ibm kernel: [ 8075.624705] Key4Str is Invalid key length(0) or Type(0) Jan 11 16:16:26 ibm kernel: [ 8075.625355] 1.

I have been useing Ubuntu for 1-2years now. Lately I've been having some troubles with my wireless Internet connection, almost every 1min i disconnect and connect again few sec after and thats like hell if you try to fx. update. I have 85-92% signal so thats not my problem.I use Ubuntu 10.04 and the standard network manager. I'm connected to a netgear router and my computer is a acer aspire one.
Ive recently switched over to AT&T Uverse TV/Internet service and I've noticed that when I ssh into my linux( 2.6.18-194.3.1.el5xen CentOS) server I get disconnected. When I'm using putty it gives the "network error software caused connection abort" error. When I'm at work using one of our jump servers and ssh'ing from the command line it will freeze up from time to time but never disconnects. I think the problem is either with the OS or the new AT&T modem. At first I had my CentOS server using DHCP and it would disconnect within a few minutes after I ssh'ed. I switched over to a static IP and now it goes about 10 minutes before it disconnects. It doesnt matter if I'm actively typing or not, so it's not an inactivity issue. I have the firewall turned off on my laptop, and since the issue happens on multiple devices, including my iphone I dont think thats the issue.
I have iptables and selinux turned off/disabled so thats not it. In putty I have enabled Keep Alive(30 seconds) and it still disconnects. I opened the port on the modem to allow ssh for the IP of the linux server. Ive also recently reinstalled this server with CentOS so I can't compare with the previous internet provider as I didn't reinstall until after I switched over. BUT previous installs with CentOS 5.2 worked fine with the previous ISP. AT&T Modem is a 2wire 3800HGV-B
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I tough that firefox was the problem of my very slow web sites loading, but I am suspecting that sometimes the internet connection is the reason, maybe for some reason that I don't know it can not just connect to the site.I am running Linux quick-desktop 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux.when I browse the web it is very slow to load.sometimes I get this error message.Could not locate remote server.Even I know the site is up running like google.
I'm thrilled using wicd to connect to wireless networks. But when I suspend my laptop using the special keys, I just want to disconnect from wireless without having to use any kind of GUI or curses user interface. It says in the documentation that wicd works by sending DBUS messages, so presumably it's possible to write a command that talks to the daemon directly.But I can't figure out how.Does anybody know by means of what shell command I can tell the wicd daemon to disconnect me from my wireless network?
My network is barely functional. I'm running 2 linux servers connected by openvpn (tun) through routers on both sides. There are Windows clients (98 and XP) on both subnets. One server (ls3) acting as PDC for the domain. The Windows clients use the respective linux boxes as gateways. On the server side (ls3 which is both openvpn server and samba server), all the clients can read/write properly to shares on both sides. The problems are all on the client side. Share connections to the server side disconnect after a few moments.
Browsing on the client side windows machines is fine. I can see shares on the server side. Some server side files open and are readable, writable, other server side files will not open. Some samba logon scripts on the server side can be opened from the client side. Others open after a long wait to a blank file! Permissions on server side files are set to 777 for testing. If a file won't open or reads "blank", that doesn't change no matter how many times you try. A non-readable/writable file overwritten by a readable/writable one can be read and written to!
I can ping successfully from any client on either side to any other client by either ip address or workstation name. Firewalls on both side are set to forward tcp and udp traffic going to port 1194 to the respective gateway linux boxes. Iptables on both linux gateways are down for testing. I tried reversing the openvpn server/client roles with the same result; the same physical side of the network had the problem. On one of the windows 98 clients, I wiped out the networking configuration completely and rebuilt it from scratch. Same result.
One one of the windows xp clients, I tried to rejoin the domain. It went through successfully but the result was the same as above. The network was operating smoothly for several years until the client side dsl modem broke last week. It was replaced with a newer model and at the same time I migrated from a pptp connection to openvpn. How to resolve this, Is this something to do with openvpn? Is this a network hardware problem? Am I missing something in the port forwarding on the routers? My smb.conf files are ancient except I added interface tun0. I have never seen 2 files sitting next to each other in the same directory where one opens and the other doesn't!
I'm running Mandrake 9.2 on the client side and Mandriva 2008 on the server side. I have a Sonicwall firewall on the server side, a Westell 7500 on the client side. I note that during the modem install, the http port was opened to the linux box on the client side and the access log got huge over the weekend and I ran out of disk space until I closed it down and deleted the log. I tried a simple test while viewing /var/log/daemons/errors on the client side. From a windows workstation in the client subnet, I opened a dos window and tried to print a file located on the samba server on the openvpn server machine which I knew NOT to be problematic.
The file printed and there were no errors reported in the log. I repeated the test with a known problematic file. The file would not print. The errors log noted: Authenticate/Decrypt packet error: packet HMAC authentication failed I regenerated the static.key file on the server side and scp'd it to the client side and restarted both openvpn's. I checked for duplicate files named static.key on both sides. Same error.
use kubuntu 9.10 64-bit on AMD Turion M500 machine.The network keeps disconnecting periodically or on some heavy activity The connection is totally stable on windows 7 though.My doubts point to network manager and so my next step is to switch to command line wpa_supplicant
A month ago I had (and still have) a weird problem were leaving my switched off computer plugged into the network killed the whole network.
well I have found a fix, if I disconnect my computer via software (Right click and disconnect "eth1" and shut down the network will remain up. I want to make a script that runs on shutdown that simply disconnects "eth1". Are there any pre-made shutdown scripts in ubuntu that I can simply add "eth1 enabled = 0" or something.
i installed linux at home on my laptop (dv2000, hp). Because i was having problems connecting to the internet through wireless. And wired at friends houses.So installed linux. Wireless took me a while but finally got that working. Now the problem i have is that wired is not working apart from at home. Any other router apart from mine it cannot connect to.
Hi - I am new to Linux and Ubuntu so I have no idea how to fix or problem solve unfortunately I installed Ubuntu 9.10 from scratch recently on this laptop and all was good. I connected to my WIFI network no problem. It's WPA PSK encrypted, DHCP enabled. I just set it up in Network Manager and it was all fine. Then after a few days I installed a printer and some packages and updates via synaptics. The network connection started dropping after 20 mins or so. Only a reboot would restore it - auto connects at first, runs fine till it drops then never will reconnect. I posted on here, someone gave me some lines to put in a config file. I tried that. I didn't seem to help much, problem remained. Yesterday I checked for updates and there were a whole bunch so I just installed them all. Now I cannot connect at all. I have deleted and recreated the connection in Network Manager but it doesn't help. It tries to establish a connection but never achieves it. I am connecting to the internet now on the same laptop booted into Windows, so all the hardware is fine.
Can anyone who knows about ubuntu networking help? Do I need to do a complete reinstall? Seems a bit much, but it worked when I initially installed the OS. I want to like Ubuntu, but something as basic as connecting to the internet is pretty vital so reluctantly having to start using Windows again...
I just got my first laptop, an ASUS eee pc 1201n. It came with Windows 7, but i decided to load the latest version of Ubuntu Netbook Edition on it as well.Today when I tried to access the internet via my library's free wireless service I couldn't get Ubuntu to recognize any wireless connections. I checked with Windows 7 and several networks appeared, including my libraries, but Ubuntu was blank.
I installed Jolicloud OS with Windows XP before because Windows XP have too many virus to attachment to Internet so whenever I go on the internet, most of the link take us to random site so I just installed Jolicloud OS however, some reason, I don't like Jolicloud very much because it require to enter the user name and password to link Jolicloud so wasted my time to use it... Its cool but pointless.
So, I just realised Ubuntu also provided free Ubuntu OS for netbook. After I downloaded Ubuntu desktop 11.04 and installed the system (all the datas is now gone and only current OS is Ubuntu)So, once I installed it... The netbook seem running well and no problem however, there is a huge problem is wireless are not found so I can't even use the Internet!.This netbook only got wireless and nothing else to connect like cable (wired).
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
Ubuntu 10.04: no problems to connect to secured wifi networks. However, when trying to establish a connection to an insecure wifi after some time I get the message "disconnected, you are now offline" without ever having been connected. Once out of about 30 times I get a normal connection. My eeePC 1005HA is double boot and I can connect from WinXP without problems. There seems to be a DHCP timeout (see attached output of syslog). I have seen some posts about the same problem but none of them had a solution. I hate it to use WinXP just for the sake of connecting to the spot.
Just installed ubuntu 11.04 on an old pc. At first, I was unable use my wireless usb adapter (netgear wpn111), but was successful after installing ndiswrapper-common and ndiswrapper-utils-1.9 manually. cool! then I updated all packages successfully via synaptic package manager and rebooted.now I have lost network connectivity. the os still sees the wireless usb adapter, but I have no connectivity. the indicator applet shows an exclamation point.
How can I troubleshoot this? are there logs? can I fallback to a previous good state?I am new to ubuntu, but experienced in unix. note: my pc only has 1/2 GB memory if that matters. but, hey, it worked once.
I just finished upgrading from 9.10 to 10.04 via the Update Manager. My first noticeable problem is that my wireless connection with my home network no longer functions on my IBM Thinkpad T42 laptop.The Network Manager applet shows that it detects my home network (and those of several of my neighbors), but I have not been able to get it to connect to this network. I've been using WPA & WPA2 Personal settings for security, and the Network Manager applet had correctly picked up the password that I had been using under 9.10. I've searched the Ubuntu Forums for "wireless T42" and thought I'd found a solution in a posting that recommended using the "wcid" network manager, but I've been unable to find wcid either via the Synaptic Package Manager or the Ubuntu Software Center.
1. I've noticed that in Lucid Lynx the Network Manager applet's icon in the top panel is no longer the vertical bars symbol that it displayed in Karmic Koala; instead, the icon is a radiating fan display. In the Network Manager's edit Network Connections window, this fan icon is shown on the Wireless Connection tab, while the vertical bars icon is shown on the Mobile Broadband tab.
2. The Wireless Connection tab shows, on the line in which it shows awareness of my home wireless network (as "Auto 389690") that this connection was "Last Used" "1 month ago". It should be saying something like "today".
FWIW, the Network Manager detected my wired "eth0" connection with no difficulty.Both Jaunty and Karmic picked up my home wireless connection without any problems. Now I have no idea what to try next.
I'm trying to connect to a hidden wireless network in ubuntu through the terminal but i am unable to do so.
I first tried using ifconfig,iwconfig and dhclient initially but i am only able to get an ip address without the default gateway and dns server addresses which i normally get through the network manager applet.
Then i tried using cnetworkmanager but failed miserably again i keep getting this error
Another applet is running: Bus name already exists: org.freedesktop.NetworkManagerUserSettings (pid 1851)
Then i used nmcli available with the network manager package. i was able to establish a connection only with the connections showed in the list. i use a hidden wireless network. i am unable to connect to the hidden wireless network using nmcli without actually creating a connection from the network manager applet.
I'm trying to set up a wireless or wired network (wireless would be better...) to share my connection with my housemate, as well as with some devices. The only guide I found regarding this (I must admit, I didn't have much time to put into research), was dating back to 2005, and although doable, seemed somewhat confusing. Getting to the point: is there a way (maybe a standalone program, or some kind of plugin) to share a connection?
I've installed F10 on my laptop since few days and I'm facing an annoying networking issue: the network connection seems to work well when, suddently, it goes down for a while, and then come back.This happens with both wired and wireless (Intel PRO/ Wireless 3945ABG) connection.
I was on my wireless network when I accidently switched on "airplane mode". Several reboots later and I can't get back onto my network. It keeps prompting for a password, even though it's the correct password. I've booted into Mac OSX & Windows on the same laptop and they connect no problems.
How can I delete the network connection to take it from the top again ? You used to be able to right click on the network connection in F14, select "edit connections" and then delete anything that was offending. That seems to have been removed now though ? Where is it stored and where can I kill it ?
I'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.
I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.
My computer takes a while to connect to my Linksys N router.
It used to connect in a snap of your finger automatically.
Now it does not.
Yes I have tried manual configuration, and double checking the password, ssid, protocols, and security type.
WPA2 personal is the security type.
There are maybe 4 different ways I know how to connect. The most annoying thing is when this box pops up saying to type in a password for the network connection.. and keeps popping up even when everything is right.
All I need is a reliable, easy, and automatic program to connect me to the internet, maybe even before I log into my system.
Linux Ubuntu 8.04 LTS Desktop Edition is my system. Brilliant system.
