Ubuntu Networking :: Upgrading To 10.10 Now Occasionally Crashes Wireless?
Oct 22, 2010
I have an HP 311c netbook which was dual booted XP home and Ubuntu 10.04. Everything worked fine apart from the internal wireless modem (the only reason I needed XP as it worked under Windows) I then upgraded to 10.10 and that started my network problems.
I upgraded Ubuntu using terminal and update-manager, which went ok. The network was identified, but more often than not it now seems to crash the network (and seems to happen sporadically too) - seems to be at some stage whenever the netbook is on now. This then prevents all other PCs/Ipods from accessing the internet. The only way to recover is to reboot my wireless network and the internet modem (and shutdown the netbook).
I got so infuriated with it that I clean installed from a USB key I created, Wireless network runs fine with all other PCs and IP equipment
Network: Linksys 11 B
Internet modem Virgin Media
One strange thing that happened when I upgraded, but seems to have now disappeared, is that I managed to get it to identify and actually use the internal modem, although that 'Mobile Internet' option under Network Manager has now disappeared from the list, so I cannot activate it..

Yesterday, I upgraded my Ubuntu system from 8.04 to 10.04. The installation process went smoothly, and the first boot of 10.04 was very smooth. However, after I selected 10.04 from my boot screen, the start-up process went very slow and then froze at a black screen. I shut it down and restarted it, only to have it load normally.
This happens on and off and I don't know why it's doing this.Does anyone have any idea what this could be or has had the same problems?

I just upgraded to Kubuntu 11.04 and I have a problem with network manager. When I plug in my LAN, everything works fine, but when I try to use my wireless connection, everything hangs after a few seconds. I'm guessing it's a cpu overload problem, since CPU fan starts after a while. But I can't move my mouse and keyboard doesn't work either. I tried network-manager-gnome and reinstalling wireless driver, but it didn't solve the problem.

During NFS transfers my laptop crashes my entire wireless network. Laptop is a Samsung R20, Ubuntu 32-bit 10.04 with atheros AR5001 wifi and ath5k driver. What works: ->NFS is working. I have 3 other machines on wired connections that use NFS happily. And the NFS shares work fine if i plug the laptop into a wired connection. ->Wifi works. I can browse the internet and a large download (700MB) with bittorrent takes 8 mins and doesn't down the wireless.
What doesn't work: ->NFS and wireless together. Any NFS transfer over wireless eventually downs the wifi. Forl example streaming one 3mb mp3 in rhythmbox crashes wireless after playing for about 30 seconds. When the wireless fails it breaks for ALL computers and the only way to re=establish it is by restarting the router. Wired connections remain OK even when wireless is down (both from the same router).->I have a 64-bit desktop with wifi that also suffers the same problem but that doesn't matter so much since it also has a wired connection.

Last night I already succeeded upgrading to 10.10 (Maverick meerkat), on previous version I never face wireless issue after installed additional package (sudo apt-get install b43-fwcutter). But after upgrading I saw the wireless is disabled and the hardware indicator light off. I used Lenovo notebook.
This is my wireless detail info code...

I am using an HP dv6 series laptop. The wireless works fine in Ubuntu 9.10 (must install the Broadcom STA wireless driver). When I try to use Kubuntu 9.10 my computer crashes when I try to install the driver. Is there any particular reason why it works in one and not the other?

my computer is very slow to view regular web pages, and generally fails to load them. It seems to be a problem specifically with webpages - I can work over SSH, use email, transfer files over FTP connections, with no noticeable problems, but any regular website (including this one) can take an age to load. This happens regardless of the browser I use (at least, it happens on Firefox, Opera, and Chromium), and regardless of wired or wireless connection (though admittedly I've not tried using a wired connection very much). As far as I can tell, it can also happen on any website. It is specific to linux - my computer is dual-boot ubuntu 10.04/Windows XP, and there is no networking problem when I use Windows.

I upgraded the wireless card in my laptop (sony VAIO CW) due to the original Atheros being incurably slow.The new card is an Intel 6300 ultimate n. In Windows 7, after installing the relevant drivers everything worked without a hitch.In my Ubuntu 10.04 installation, however, I have been unable to get it working.Initially I had the compat-wireless modules installed (linux-backports-modules-wireless-generic), as I had done so to try and get the Atheros card working better. I tried removing all of these, and that made the difference that iwconfig now (instead of nothing) listed
Code:
wlan1 IEEE 802.11abgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=16 dBm

I had some problems upgrading from 10.4 to 10.10, and I had to select the "safe mode" equivalent option in the grub loader to boot, or else my system would hang at the screen with the dots before the login prompt. I restored the packages and now my system works. I am not sure if this is relevant to my problem.
K9Copy worked fine prior to upgrading to 10.10, now it crashes as soon as I load it. I have searched but found nothing relevant to my problem.

Previous X was 1.4.2. After aptitude upgraded X Window to 1.7.7, startx crashed complaining: XKB could not find /usr/share/../rules/evdev file. There is no evdev file.
How do I modify xorg.conf to work with evdev? I spent few hours to figure out evdev. It seems it's new style of managing input devices in X Window. The information isn't friendly to migrate from old to this.
When I put Option "AutoAddDevices" "off" in ServerLayout section, it literally froze X Window. X started without mouse/keyboard control. I had to turn off power switch. Now, I can't use X at all unless I move back to 1.4.2.

I have a Mandriva linux box connected by cable to my router. When I stream audio using this box it crashes all the wireless computers on my network. There is no effect on wired computers. All but the one computer are windows (xp or vista). The affected wireless computers are not able to even find my wireless network. I have to reboot the router to get them online.

I have recently upgraded my USB wireless network connection for one of my computers to N from G. As I am (temporarily) based in China the device (and all documentation) are in Chinese. I THINK it is based on a Ralink 28XX chip. I am running Ubuntu 10.04. Network Manager claims that the wireless network is disconnected does not list any sources This is the basic info that I am able to find (I am using these commands in ignorance, by the way!) lsusb shows:
Code:
Bus 002 Device 002: ID 1d57:d2d1
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 148f:3070 Ralink Technology, Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
dmesg shows (after plugging the thing in):
Code:
[ 2081.028069] usb 1-1: new high speed USB device using ehci_hcd and address 5
[ 2081.178000] usb 1-1: configuration #1 chosen from 1 choice

I currently have a WiFi network at home that serves two PC's, a Laptop (all SUSE 11.3) and a couple of WiFi radios. I also use IPCop as the Firewall. The system currently uses 802.11g, but the PC's and Laptop really struggle to achieve any reasonable internet data speeds, particularly as their RF range to the Wireless Router is very disappointing, so I have a couple Wireless Access Points. Unfortunately, whilst these WAPs might slightly improve RF coverage, connecting to the Router via one of them only serves to slow down the internet upload and download speeds even further. (Not much point in paying for expensive 4M internet access if I am only achieving a typical download of 500-600k!)
I want to completely replace my 802.11g with 802.11n - to both improve range and throughput. I'm looking at the 'Netgear Range Max Dual Band Wireless-N Gigabit Router' as this also has 2.4GHz (my WiFI radios are only 2.4GHz compatible). Unless, of course, anyone has any good reason to recommend I DON'T purchase it? My problem is that I am struggling to find up to date, accurate information that can advise me on which 802.11n (2.4GHz and 5GHz) PCI cards, PCMCIA and USB Adapters are compatible with SUSE.

I've got the justice edition of sauerbraten, from the tarball on their website (though I didn't have to compile it). Occasionally, when I run it on multiplayer, a map will freeze it. I can't get to a tty unless I first type alt+sysrq+r to release keyboard control from x. Then, I can do ps aux | grep sauer to find it's pid to kill, yet it still gives nothing on x. I then kill all kde things, do sudo service gdm stop and sudo service gdm start, which gets me back to a usable desktop, but weird things will go wrong, like fonts will be the wrong colour. So, to get it back to normal, I have to restart. Is there any way (preferably without actually killing x) of getting my screen back without restarting? I have an integrated intel graphics card, and sauerbraten normally runs at an allright speed.

I'm now on 11.04 (64 bit on a desktop), but had the problem on 10 as well. I get the occasional complete system freeze. There is nothing in the logs indicating a problem and it is not the graphics card, as I cannot ssh in from another machine. It sometimes happens after three days of running and sometimes after 20 hours.

I accidentally powered down in the middle of a session by removing the wrong battery from my laptop (a Motion Computing tablet), and ever since that happened knetworkmanager crashes with a segmentation fault on startup. I have uninstalled it and then reinstalled it from an openSuse 11.4 DVD I made a few months ago, but it still crashes on startup. Ifup says it connects to the wifi (Wayport Access @ McDonalds) I have available, but browsers don't reach the internet while Ifup is connected, so I can't sign on and get access to anything more recent. Is there some file I ought to delete,or some other software I ought to delete and reinstall?

today I installed Opensuse 11.3 on my new laptop, a Samsung R540. Initially I got my Logitech bluetooth mouse working because I hate the touch pad, then I got the wireless network working by upgrading the kernel with the broadcom-wl package at which point the Logitech bluetooth mouse stopped working. I am able to detect the mouse when I go to add new devices using the gnome-bluetooth applet but it times out when it tries to connect.

The odd time I boot my laptop the screen resolution will change to 1024x768 and I would have to change it back to 1200x800. Not only that but I would have to move all the applets on the panel, to where they were.
This has been happening since I've first installed Ubuntu 7.10 and continues to 10.04.
Here's some information about my screen. sudo lshw -C video:

This problem started a few days ago. Whenever I attempt to connect to a wireless connection via network manager, my computer completely crashes, going to a black screen with no input from keyboard or mouse. It forces me to reboot using the power switch. Everything works fine when I connect to an ethernet cable, so I am sure it's a problem with my wireless driver.
I already tried (successfully) reinstalling the ath9k driver via compat wireless as was the advice from other forums, but this had no effect. I'm currently running opensuse 11.4, and haven't had this problem until a few days ago
This problem seems a bit ridiculous for a task as simple as connecting to a wireless network, so I'm convinced that either there is some sort of relatively simple way of fixing it, or windows really is the only decent operating system out there..

I am using 10.4 on a Toshiba satellite pro L100 and have got it working well enough with ubuntu. However, every now and again it freezes on start up and I think it may be before the automatic disc driver check and scan that happens on start up now and again. It gets stuck and tells me
[ 33.117318][drm:rs400_gart_adjust_size]*ERROR*forcing to 32M GART SIZE (because of ASIC bug?)
I only ask as I have to do a hard shut down and computers don't like them do they?

I recently installed Suse 11.4 on my Dell Latitude 2110 netbook using the KDE live distribution, and, after that, the Broadcom wireless ceased to work. To enable the wireless connection, I have to press Fn + F6. If I do it now, the wireless led indicator turns on for a couple of seconds, then turns off again. Moreover, the option to enable the wireless connection in the network manager is greyed out

When I run a java application (minecraft) the computer occasionally freezes. I'm not sure which version of Java I have. The online java app for telling you which version I have says that I have an old version. The command line says I have an up to date version. If I need to update Java Sun , how do I do it ? I followed the instructions once and didn't work.

I'm setting up a htpc system (Zotac IONITX-F based) based upon a minimal install of ubuntu 9.10, with no GUI other than xbmc. It's connected to my router (d-link dir-615) over a wifi connection configured for static IP (ath9k driver), with the following /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
# The primary network interface
#auto eth0
[code]....
Network is fine, samba share to the media direction works, until I try to upload a large file to it from my desktop system. Then it downloads a couple of percents at a really nice speed, but then it stalls and the box becomes unpingable (Destination Host Unreachable), even after canceling the transfer, requiring a restart of the network.
Same thing when I scp the file from my desktop system to the htpc, same thing when I ssh into the htpc, and scp the file from there. Occasionally (rarely) the file does pass through, but most of the time the problem repeats itself. Transfer of small text files causes no problems, and the same goes for the fanart downloads done by xbmc. I tried the solution proposed in this thread, and set mtu to 800 in the interfaces file, but the problem persists.

I am running Fedora 14 with kernel 2.6.35.74 x86_64 and I am having an issue with a Vfat partition that is shared with Windows 7 on a dual boot setup. this partition contains my mozilla profiles and it occasionally mounts as read only in Fedora. I wont be able to write to it and root doesnt seem to be able to write to it when this happens. I checked this by trying to redirect an output of ifconfig. My fstab entry looks like this.
Code:
UUID=5830-75A8 /home/joe/share_storage vfat rw,umask=0000,uid=500,gid=joe 0 0
and ls -l
Code:
drwxrwxrwx. 8 joe joe 4096 Dec 31 1969
These two (fstab and ls -l) always look the same whether the partition behaves as read only or not.

I upgraded to FC15 in early june, come June 15 Thunderbird suddenly ceases to send or receive any email. It pops up with the message "You may have exceeded you maximum connections" and I've tried changing the cache connection count to 1 instead of the default 5 and every OTHER post about that error suggests to no avail. Funny thing, my primary desktop is still on FC13, same thunderbird version, arch and account setup (with SSL enabled) and works flawlessly. Even with -safe-mode enabled it doesn't work. My lightning calendar also doesn't sync since then.
I have found that if I turn SSL off IMAP works again, SSL SMTP still fails. If I turn SMTP SSL off it sends mail. The calendar is an https (SSL) link. Obviously the issue is SSL and Thunderbird in FC15. There are no errors/messages in the console, maillog or the in-built error console. I will NOT use mail without SSL as I may occasionally use unencrypted WiFi.

I'm running a generic kernel with Slackware64 13.37 multilib. Every now and then it freezes at the boot time. It probably happens 1 every 5-7 times, so it's not a big problem, but it indicates that something is not right.
