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 network...like 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 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. uname -r
I'm not sure if this started with the 2.6.34.4 or 2.6.34.7 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?
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.
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.
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.
Hey all, I have got this strange problem with my Slackware server acting as router and gateway to my internal network. It randomly disconnects the WAN connection after X days ( it is between 2-7 days ). This error messages occured in /var/log/messages just before it lost its WAN connection:
Feb 20 14:36:00 tml dhcpcd: eth1: failed to renew, attempting to rebind
When I first turn it on to the desktop, it automatically connects and disconnects automatically 5 times then sometimes it would disconnect a few times randomly out of the blue.
This ia an external single usb wireless adapter you plug in the usb port on my desktop tower.
This is going to sound weird but my wifi interconnection is really good i never have any problems but when i open skype, go to options and click test webcam my wifi disconnects and will not return till i restart the pc
I'm running 10.04
keep the connection and the webcam working will be great
I am on a toshiba laptop with a wireless internet connection, I have recently purchased a logitech pro 9000 webcam , I plan on using it for skype. So the wifi is working fine, I plug in the usb webcam and all of the sudden I just lose connection and my keyring doesn't even remember the wep key for my wifi. I am amateur with linux based system but I have taken a operation system class so I know some stuff and can follow instructions quite well.
I have experienced sudden wifi disconnects. My laptop fails to reconnect even after repeated attempts. It is only after a reboot that I am able to connect to the wireless.
I have an hp compaq 6720s laptop dualboot vista/ubuntu lucyd.My wireless card is Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02), controlled by wicd 1.7.0 (gnome network manager connects/disconects the net continuously).The problem is, any time I do a scanning with wicd or from command line to see the wifi nets around,my wireless is disconnected, then it connects again because is set to automatic reconnection
I have a Dell Studio 1737 running Ubuntu 10.04 LTS.My WiFi was working fine a few days ago until I tried to boot into another mode that allows me to boot into my other Ubuntu 10.04 or Windows Vista.I booted into that Ubuntu, which I thought had been overwritten when I was having problems and installed the one I am currently using.I shut down since it didn't have anything of any use to me at the moment, and I booted back into this current Ubuntu.Now, whenever I shut my laptop screen and open it back up to login, the WiFi is disconnected.(I was also having this problem on the Ubuntu that I booted into earlier, but that WiFi did this from the start on that one.)
About 20 seconds after I unplug my Laptop from the AC adapter myiFi connection disconnects. The only way to get a connection again is to shut down my laptop and remove the battery and the AC adapter (WiFi-adapter reset) and reboot my laptop. I'm running 10.10 32-bit.lspci shows me these information about my WiFi-Adapter
I have a Lenovo T440p.I am on Debian Jessie. I use KDE as my desktop environment. My Wifi adapter is IntelĀ® Dual Band Wireless-N 7260. I have configured my laptop not to suspend itself when the lid is down. I can verify that the laptop still runs when the lid is down, because I can hear the music if it is already playing. However the Wifi always disconnects when the lid is down. If I am downloading a file, it always gets interrupted.
After a new fresh-from-DVD install of Fedora 14 64-bit (over top of Fedora 12 64-bit which went over top of Fedora 10 64-bit before that) my Linksys WUSB600N adapter connects at login to my WiFi N router with WPA2 Personal.
That is great, as previously (fc10/12) I had to use the Ralink drivers per ogetbilo's thread on this forum (that thread kept me on the net for many years now). And at some point this even became a pain because sometimes the system would boot and refuse to connect to the wireless (which would hang trying to connect) and then crash to a dump screen on shutdown (bug reported). The fix was hoped to be found in upgrading to F14 and the newer kernels with working native Ralink chip support.
But I still have an issue... the connection stays up for a few minutes then drops. If I disable/re-enable wireless it (at least sometimes) re-connects. But obviously that is not workable. This is a USB adapter and I am not entirely sure that there is not some USB powersave issue going on, but I do not see anywhere to disable system USB power saving either.
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
I have an Asus laptop with a BCM4318 wifi chipset. result of lspsci command about wifi cards:
Code: 00:09.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) For some reason, I often get disconnected. Once it's disconnected, I cannot connect anymore and I need to reboot my laptop in order to get the connection back! I didn't have this problem when I was on Ubuntu 8.04. I checked in /var/log/syslog and I found this when the network is disconnected:
I 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.
I have a strange problem; I did an upgrade to ubuntu 10.10 succesfully. But now sometimes when I activate something (anything from O-O to synaptic or whatever) the OS just shuts down .I don't get any fault messages or other stuff.
I have upgraded a friends notebook from 10.04 to 10.10. Everything was fine with 10.04.The upgrade process runed smoothly but after booting 10.10 the X system randomly restarts. It seems to not be able to run for more than 10 minutes without X abruptly restarting and the login page being presented. I still couldn't even identify some pattern nor relate the restarts with some specific software.I've looked in /var/log/messages but there is nothing registered there that seems to be related to this issue.Despite being an old notebook, I don't think it's hardware related because the problem appeared for the first time after Ubuntu upgrade and it keeps repeating itself after that.
On my computer, I mount at boot time through the /etc/fstab some shares.I was working flawlessly on 9.04 and previous version.Since 9.10 version, it sometime fails to mount the share and I need to run PHP Code:sudo mount -a to get my mount shared mounted. (the command "mount -a" always work).
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.
Suffice to say I had a dual boot at work with an essential windows 7 and non-essential linux install on it, and randomly upgrading the distro made windows7 unbootable. Cue a missed days work, much embarrassment and ear bashing from those who are convinced Linux is written entirely by communists and hippies. In the end I had to re-install windows, which cut off the ability to boot to ubuntu - although I've left the existing ubuntu partitions as they were.
Although I can get away with allocating a few partitions to ubuntu, I can't really justify fiddling with the MBR based upon this experience. I need a fast boot and persistent data for doing anything further with ubuntu at work, so I'm wondering whether a safer bet would be to setup a usb stick with enough grub to boot to the existing ubuntu install? Not a full usb distribution, just enough to boot into the existing install? how this would be doneIs it really just a grub-install /dev/sdXX (where XX is the usb)?
I just completed the upgrade to 10.04 LTS and have noticed an issue with my wifi in KDE (Kubuntu) not acquiring my IP address. The wifi works fine in Ubuntu and Lubuntu.
I have lost wifi access with the upgrade to 11.4.Previously, the receiver icon showed on left click a menu of available networks, and on right click, available network by network settings for editing. The menu also included enable wireless connection and enable wired connection. I have wireless enabled.
But with the upgrade, the same menu appears on left click or right click, and they both show a greyed out "wireless disconnected" tab, so you can't connect from there, the tab is disabled. There's also no place else to go to find available networks or to lock into one. There also does not seem to be a place to find wired networks either.I installed my wifi network in it, and put in the correct password and set it to come on automatically, and 3x restarts did not yield any changes. Apparently network finding is disabled in this version or at least my copy.It isn't the computer: I'm on line with it now on the Windows XP side.
This is doubly problematic because if I can't get on line, I can't download a fix, and even if I could by downloading it to the Windows side, it is probably a binary with some very scripts and meticulous BASH coding or tarballing something else that I have no idea how to do even with a walk through by an expert because most of the time the experts assume I know as much about using a Linux terminal and code as they do, and I basically know absolutely nothing, it is all Greek to me from the point at which they say "open a terminal." "Go to root" might as well be said in Chinese as far as its usefulness to me. What is the plan here? A complete redo from the get go?
i have Dell 1535. I installed Kubuntu 11.04 on it, now wifi is not working at all. Here is the output of some command i saw already in previous post related to this problem.
I updated successfully to 10.04 via wireless, then I downloadsynthesizer via wireless. The next day, today that is, can't get wireless to work. It keeps prompting mor the passphrase, I enter everything correctly, all the other computers in the house have no problem.
