Ubuntu Networking :: Wireless Connection Not Stay Connected For Long
Feb 8, 2010
When I turn on the computer, it connects to wireless automatically. That's good. But it doesn't stay connected very long. Especially if I turn on a p2p program or make a call through messenger. Then I get disconnected suddenly and if I want to connect again it doesn't work anymore. Network - You are now disconnected and that's it. Every time it happens I restart the system. I use an Acer Aspire 5738z laptop.
I am running Ubuntu 10.10 on a Dell Dimension 4700 desktop computer. I just upgraded to 10.10 from the previous version after getting my D-Link wireless adapter back after loaning it out. My internet now won't stay connected. I can connect when I firstrn on the computer, with after 2-5 minutes it drops the connection and gives me the "Wireless Network Authentication Required" prompt. It won't connect again without unplugging the adapter and plugging it back in.I borrowed a Belkin wirelss adapter to try it, and it does the exact same thing. PLEASE can someone help me, I really need the internet up on the computer(Also, when I first got the adapter-- while running the old version of Ubuntu-- it would not recognize or connect at all and I spent 4 hours messing with drivers and settings to get it to work, which it did flawlessly. Until I upgraded.)
I am not new to linux, but brand new to wireless. I partined in Win 7, loaded Ubuntu 10.4 and seemingly on boot I am connected wireless as I am in Win 7. However the moment I open Firefox I am no longer on line. Its not important to discussion, but I am not a avid windows fan and at 80 Linux is my hobby having experienced 8-10 distros.So I hope someone out there has the patience to advise me. Thank you so much for reading my tale of woe
having trouble with my asus 1000 rt2860 wireless n card and WPA/PSK/WPA2 connections. Funky thing is it worked in the 2.26.32-21 kernel (iwconfig shows ra0 as the wireless interface), but when the kernel was updated and pushed through in the ubuntu updates to 2.26.32-22 the wireless card won't stay connected and iwconfig says wlan0 is the interface. I checked the proprietary drivers and they said that the driver for my card was active, but not in use. How do I use the ra0 instead of wlan0?
how do i use the driver that's listed as not being used? I'm having to boot up lucid with the older kernel now, it's annoying, lots of programs aren't running as expected as a result. I've tried manually installing the driver from the RaLink website as detailed in many other posts concerning this wireless card. It seems to work for some people, but not with me.
I am running a dual-boot with Ubuntu 10.10 and Windows 7 and I can't stay connected to the internet with Ubuntu, but Windows does. My router is a D-Link GamerLounge DGL-4500. I have wireless internet access for about 10 seconds but then it drops. Access to the router doesn't go away though. Other computers can connect to it just fine, and my computer (Toshiba Satellite A505) has connected to every other one I've tried on. I can still log in to it and change settings and all that, but I can't access the internet through it. I also can't ping the router.
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
Ubuntu 9.10 working great. Installed Orange 515m as per fix shared on this and other forums; however while it works great at home, it will only 'connect' once at work - on subsequent attempts it connects, but browser etc behave as though they cannot find the modem and I cannot make further connections via gmail and Firefox. I had just made the swap from Win 7 to Ubuntu 9.10 for work as well as home, but I cannot be in the position of being unable to access my emails and so swapped my hard drive back to Win 7 drive today
Situation: Someone intelligent physically dropped a HD from a dying machine into a newer one, things magically went well (with exception of X, fixed) and now we have this NIC problem. The owners of the server refuse to upgrade to fedora 12 unless there is no other choice, so here I am consulting the experts as I promised i would Ty for your help in advance

As part of my transition moving away from Windows altogether, I've been trying to get the VPN to work properly under Ubuntu 10.10 32bit, through the wifi connection. The provider is Ivacy, using PPTP, and the usual instructions (below) are followed: [URL]. The VPN originally connects fine, browsing etc works all fine, for a limited period of time though. Within roughly 10min the connection stops working; I'm not yet sure whether the determining factor is time or bandwidth, but it remains short-lived...
There is no indication of the VPN connection dropping, it seems to remain connected, but no packets are received. To get the internet working again I have to manually disconnect from the VPN; then I can browse without the VPN, or reconnect the VPN and it will work for another small lapse of time. In addition, I'm not sure if this related, but after reconnecting a few times to the VPN as described above, eventually I get an error message, "failed to start the VPN service" (or words to that effect). The VPN connection worked very reliably under Windows.
I am useing a PC as a simple display and I need the monitor to stay on for long periods of time. I have set the power saving setting to "presentation" mode and it is not supposed to turning the monitor off. Is there somewhere else I need to adjust this??? I am running OpenSUSE 11.1.
I've recently installed 10.04 LTS on an old laptop. I've not been able to connect to the internet at all. I finally finagled some drivers for my Broadcom BCM4318, and seemed to get everything in order, but it says that the "Radio hardware status changed to DISABLED"
Then, I pushed the button on the laptop to turn the wireless on, and it worked! But then as soon as I let the button go, it turned off. Is there some way to toggle it so it's always on?
I am very new to the wonderful world of Linux and from what I've read about and my limited experience (approx. 3 hrs) I like it; but I'm having one problem that I need to get fixed: I'm dual booting currently with W7 (boo) only because I can't get my internet to stay connected(?) for extended periods of time using F15.
When I first installed F15, everything went smoothly, it asked me for my PW for the wireless internet and it said that it was connected. After I loaded Firefox for the first time, thinking to myself "Awesome, it set itself up completely and is running perfectly) I was let down. On my laptop I have Quickbuttons. Touch sensitive buttons above my F-keys (incase you didn't know what I was referring to. When I connect to the internet, with my wireless card on, I can successfully load 1 internet page. Halfway though the page load, the internet light/button starts to flash repeatedly on/off rapidly. Internet connectivity seems to have stopped at this point as I can not load another internet page or use the chat window any more. If I disconnect from my internet and reconnect, everything works fine for 1 more internet page then back to flashing and no more connectivity.
If I restart using the Windows OS, everything works fine and my desktop is working normally as well, so it must be something with F15. What do I need to do in order to get the internet card to work continuously? What am I missing? Please remember, I'm very new to this and all the troubleshooting web pages that I've found thus far are talking WAY above my head.
I have Ubuntu 10.10 on a Toshiba satellite L300 with an Atheros AR5001 wireless network card. I can get the computer to see the network but it wont persist, it keeps going offline or asking to be re connected.Also Firefox will not find the internet even if the wireless icon shows the wireless network is alive.I can use the laptop for the internet if I plug in the LAN cable but have no luck with the wireless. Security for the modem is using WPA&WPA2 and it will connect according to the icon in the title bar for the wireless network. I have tried the Atheros site for a driver but had no luck finding one. Not even sure if that is what I need to do.
I am closing this thread and ask this question in the "Network and Wireless" area. As for the installation of 10.04 - wonderful. However, my problem is not an installation problem. Ubuntu 10.04 - Fresh install on machine with no previous OS it was a beautiful install experience. I have a Linksys WUSB54GC little plug in thing that is in one of the USB ports At the top of the screen it says that the computer is connected to the network genevapubliclibrary 100%
But when I access firefox, there is no internet connection. I checked the Preferences, Advanced, Network tab, Connection and the Settings button. It is set to "No Proxy". This is the same setting as our library laptop - also wireless - in firefox but using vista. If this has been addressed elsewhere, I apologize. I tried looking for linksys wusb54gc but no one had this problem.
I did search, but could not find a solution.Right I've installed Ubuntu Server 10.10 on an old machine, installed fine and the system is running. I have a windows 7 desktop that is connected to the internet via wireless. The desktop then has an ethernet connection which is shared to the ubuntu server. The network looks like this.
Modem > Router > Desktop > Switch > Ubuntu Server My problem here is that there appears to be no connection from the server to the desktop. The server cannot connect to the internet.
When i ifconfig the ubuntu machine shows.eth0 link encap:Ethernetinet address: 192.168.137.2 Bcast:192.168.137.255 Mask 255.255.255.0 However on the windows desktop (the machine sharing the internet) these are the details for the connection to ubuntu server.ip 169.254.170.50 mask 255.255.255.0
is this a dhcp problem? is my server configured wrong?
My problem is that every time I use the Ethernet connection (I don't have wireless card) there is a delay of around 30s, even though my download speed is not affected at all once the connection is "established" , no matter what application I use (Synaptic, ssh, firefox, google chrome,wget, update manager, etc.). A weird thing is that my ethernet connection always appears as active.
I'm sure I'm not the only one who has experienced this issue, since I've read the same problem on other forums, but no one has come up with a solution. I hope that there will be a solution at last by this time. I've been around with this problem for about 1 month, I've tried all sorts of tweaks that involve disabling ipv6 and nothing happens. I don't really know what triggered off this issue because it all started all of a sudden and I don't remember having installed any important update by the time this happened (I did a clean installation of Ubuntu 10.04 32bits on the release date).
Running Ubuntu 10.10 on Hp Mini 1030nr My wireless card is a Broadcom BCM4312. I have the b43 driver installed. When I disable networking I can change to monitor mode but then it changes back to manage mode when I enable networking again. I tried using airmonNG but it;s not working.
I love using wheezy but i keep having to take my computer downstairs to hook it up to router through ethernet, i need it to connect through wifi and stay connected.
heres my problem, if i use live image and connect to network its fine but during installation process it gets to the network configuration, it will keep disconnecting at dhcp and if i try and continue it gives me the error packages broken due to it not staying connected.
MY WIFI CARD IS A TP-LINK WDN 4800
if i try and just do a net install then it doesnt show my wifi network.
it uses in both cases ar93xx atheros driver for installing, i just need to know how i can try and keep a stable connection over wifi so it can install over wifi so i dont have to keep taking pc downstairs to install it.
i done something that stopped me being able to login into wheezy i was left at black screen with blinking command line, i have reverted to mint debian until i can get a stable connection over wifi to install wheezy again.
I just installed Fedora 12 on my HP a430n PC.I used to run Fedora 10, then moved to Linux Mint 7, then to Ubuntu 9.10 and now I am back to Fedora because I want to become more adept with manual package installation and adding repos.When I ran Fedora 12 immediately after then install, before running yum update PackageKit or the software update, it would use my wireless adapter (Netgear WG111v2) and connect to and stay connected to a network just fine. No hiccups.After running the updates and restarting the computer, the wlan won't stay connected for longer than 20 seconds, which is frustrating when trying to install mp3 codecs.
This seems to be a bug in the latest driver update for the WG111v2, but I might be wrong. Anyone have a fix or a way to revert back to the initial driver (I don't know what the original wireless driver was called).
I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
For example, I have a script that writes the time to a pipe in /etc/pipe. It writes continuously in a while true loop. How long will the data in the pipe be available for reading? If I only decide to read the pipe a day later with cat /etc/pipe, will I get all the time values right from the time I started writing?
Conversely, what if my loop only wrote the time every 10 minutes. Will I be able to access everything a day later?
Finally, pretend my loop writes the time continuously (like my first example) and I read the pipe every 30 minutes. If my computer shuts down right before I read the pipe, will the pipe be empty when I reboot or will it hold all that data?
I'm running Ubuntu 9.10 with fluxbox installed. Occasionally my internet connection will stop working, but when I check on wifi radar, I'm still connected to the network. The router is not plugged into a computer at the moment, just the cable jack. It is likely a hardware problem however, since my other laptops also experience disconnects. Any help beyond "change the cable" would be greatly appreciated. For instance, even though I am connected to the network, I cannot post at the moment due to lack of internet connection.
I can connect to the wireless at my school, but the connection drops frequently and regularly. Network Manager still shows bars indicating the network strength and shows that it's connected to the network in the dropdown. Selecting the network again causes it to indicate that it disconnects and reconnects. At this point I have wireless until the connection drops again. Possibly relevant details: This is the Purdue PAL2.0 network, which can be tricky to connect to, particularly for Linux users. It's a hidden network using WPA2 and PEAP. My computer is a Dell Inspiron 1420n laptop, circa August 2007.
i done desktop config in ubuntu server 11.04 and connected via tightvnc,uvnc and in remote desktop viewer from another ubuntu machine also. I am not able to access(connect) the server in GUI mode(when monitor is removed) but i putty is working fine in cmd line.
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
i m connected it with wired bb airtel connection but its not working i have one more operating system windows 7 thats working nicely with that connection.
My mom has ubuntu 8.04.2, and it does not stay connected on the wireless usb cards. I tried 2 different ones, 1 azio and 1 is something else. But both get connected, but they die out after awhile. I am at work typing this, so I will probably try to move my router up higher or something, but it is weird it cuts out like every 15-30 minutes, and it starts at like 4 bars.
She is running it out of a live DVD( I Know, you shouldnt use a DVD as your main OS) but she only needs the internet, and uses google docs to save stuff or a USB stick. Anyone know what might be the cause of this disturbance in the connection. It is a cable connection, and the main modem is in my room, and we got a netgear router( maybe the problem?). I tried the same exact system/live dvd environment at my work place and it held connection pretty good, but I believe it did disconnect a few times as well.
