Ubuntu Networking :: Latest Image Push (2.6.32-25) Causing WLAN To Drop
Sep 8, 2010
I noticed this weekend that I began experiencing wireless issues with the NIC (Intel 5300) on my laptop. I have had no problems with the wireless using several Ubuntu versions. This began after I installed the packages associated with the Update Manager last Friday, which included the 2.6.32-25.43 kernel update. My wireless will drop out anywhere from 10 seconds to a couple minutes later after connecting to my router. Again, I have not have any wireless issues before. Below is the end of dmesg when I enable the device.

Well since tonight, after the upgrade to the latest current today, it was about a month I didn't upgrade, I cannot "git push" from my windows workstation (through msysgit shell)... I can pull, at least it tells me I'm up to date, but it keeps blocked on the 'push' command, returning only after a long timeout:
i gotta install ubuntu on 5-6 machines , The latest iso image does not offer me package upgarde (the one you get after apt-get update and dist-upgrade) . its about 300 Mb which would be a pain for downloading on different machines.. Is there a way to slip these into the iso image.
I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:
PING (REDACTED) bytes of data. 64 bytes from (REDACTED): icmp_seq=1 ttl=252 time=1.50 ms 64 bytes from (REDACTED): icmp_seq=2 ttl=252 time=2.13 ms 64 bytes from (REDACTED): icmp_seq=3 ttl=252 time=1.38 ms

Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.
I'm running Ubuntu 11.04 and I'm really new to linux. My problem is that whenever I try to browse a site I notice the website loads very slowly because it takes a long time to do lookups. I installed Ubuntu with an onboard NIC and later switched to a PCI NIC (Dlink DGE-530T). Although I disabled the onboard NIC in the BIOS, it doesn't help. Could this conflict in configuration be a problem? My download rates are fine, its just lookups that take really long ( upto ~ 10 seconds). I know the PCI network card is fine because when I jump to Windows 7, lookups are normal again (~ 300ms). At first I thought about installing the sk98lin drivers for the PCI NIC but I saw a couple of places where people have mentioned that the skge driver that comes along with the kernel is better.
I have tried a system wide as well as Firefox disable of IPv6. Here is my /etc/udev/rules.d/70-persistent-net.rules Code: # PCI device 0x1186:0x4b01 (skge) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:01:14:eb:39", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x10de:0x0373 (forcedeth) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:3e:19:ed", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" The interface I want to use according to the listing above is the one with the MAC - 00:24:01:14:eb:39.
I tried removing one of the entries in the file above and rebooting but it still didn't work. Here is a look at my /etc/network/interfaces Code: auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.10 gateway 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255
There is no wlan0 interface when trying to run FRITZ!WLAN USB Stick N 2.4 on OpenSuSE 11.2, though it works fine on Fedora 11 and Mandriva Spring 2009.1. All 64bit. Contrary to Fedora and Mandriva, there is no need to compile the compat-wireless module ar9170usb for OpenSuSE 11.2 because the kernel is very recent and includes this driver. Kernel: 2.6.31.5-0.1-desktop The /var/log/messages gives this after I put the stick in the PC. At first it is seen as a mass storage device:

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.
I'm having a problem with TCP connections taking a long time to establish, often timing out. The strange thing is it seems to only happen on some source workstations and not others in our LAN but not from home or other internet connections.I can see the SYN packet leave the source workstation, enter the firewall LAN interface, leave the firewall WAN interface and arrive at the destination server's interface. Then the SYN ACK packet doesn't get sent for 2 to 300 seconds. Once I see the SYN ACK sent from the server, the connection is ESTABLISHED.
I'm running Fedora 10 on a HP Compaq 6710b laptop. It is by far the best OS I have ever used and have no complaints, but I seem to be having some trouble with the wireless at work. The office has a single Cisco Aironet 1131 configured for WPA2 using AES with a PSK. The SSID is not broadcast. The mode is B/G mixed. My wireless card is a built-in Intel PRO 3945ABG, the driver is IWL3945 (auto configured during the OS install).
I use the Network Manager to manually add my SSID and select "WPA & WPA2 Personal" on the security tab and enter the PSK in the password field. After a few moments the wireless connects and appears to be working fine. About every 3-5 minutes while using the office network I get the "kernel error" dialog in the bottom right hand corner of my screen and the wireless drops connection. It re connects after about 30 seconds and appears to work fine until the next kernel error.
We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).
I bought an RTL8187L USB wireless adapter, and have had trouble getting it to work. I have managed to get it to work via manually configuringtime, but lost that configuration, and now it is once again not workingThe root issue appears to be (if I'm understanding correctly what I'm seeing) that when I connect, routes don't get setup properly, so when network manager (or WICD, which I've also tried) get to the DHCP step, my wireless router can't be reached by dhclient.
This is on Ubuntu 9.10, and I'm using the updated driver from realtek.com, btw, though the in-kernel driver was exhibiting the same behavior.So, two questions:- Is anyone familiar with this problem, and is there a fix available?- I believe I can work around it by setting up routes manually (e.g. with a post-connect script in WICD), but after staring at the "route" manpage, I'm not 100% sure of the commands. My router (a FIOS MI424WR) is my DHCP server, and is at 192.168.1.1, and route -n on a working PC (wired connection) gives:
Code: dave@MinasTirith:~$ route -n Kernel IP routing table
I am having problems with download speeds in Ubuntu 9.10. Downloads start at a healthy speed and then drop to almost zero. This affects apt-get install, Pan newsreader etc. With apt-get install if I terminate the download (with [Ctl][C]) and restart it I get another burst at high speed then again back to almost nothing. It makes updates a nightmare. With Pan newsreader I get high speed for most files but when downloading some of the larger files the speed drops right back to almost nothing after a while. I am on wired ethernet (no wireless). Typically I will get about 1.1MB before the speed drops - although I think it may be a function of time rather than data. I am talking to my ISP via a Netgear FWAG114 router and a NetComm NB5 ADSL modem operating in bridge mode. Although a number of users appear to have experienced very similar symptoms here I haven't found an answer that works.
I have been using Ubuntu 10.04 (32 bit) as a headless workstation, running a VNC screen. Worked perfectly for about 3 weeks, then suddenly, I lost the Drag and Drop capability, for all applications.
For example:
Dragging and dropping to move items on the desktop does not work. The item simply pops back to the original location. Dragging and dropping to move items from one folder to another does not work. Same behavior -- the item just pops back to the original location. Dragging and dropping Bookmarks in Firefox does not work. The attempted Drag and Drop is ignored. Copy and paste still works fine. The problem does NOT occur when using an attached monitor (primary display screen :0).
I suspected that the changed behavior was caused by an update (from Ubuntu Update Manager). I confirmed this with the following:
Reinstalled Ubuntu 10.04 fresh from the live cd. Configured minimal networking and installed VNC server. Tested Drag and drop -- works okay Applied pending updates (116) from Ubuntu Update Manager Tested Drag and drop -- not working
I am using vnc4server and openssh-server installed from the repositories using Synaptic.
I've been using Ubuntu 8.04 for about a year and the wireless has been fine but now it's gone screwy and I can't figure out why. This has happened on my laptop and wife's who uses Ubuntu Hardy also. The speed drops to almost 0 mb/s whenever the signal strength is less than 95%.
It isn't the internet connection as vista (I dual boot) works fine below 95% signal strength. To get the internet speed to be at a level that can load an internet page, I have to within 3 feet of the router!! Both of the laptops don't use ndiswrapper, the internet connected straight away from a fresh install.
I am running Ubuntu 9.10 on a Dell inspiron 1520 with intel 3945abg wireless card. I am fairly new to linux and just installed it earlier in the day. Everything so far has been easy to setup and get running as well as the networking or so i though...
I can connect to my network and browse we pages just fine. However, when I download a file the speed starts high, drops down to around 50kbps and then works its way back up to around 1.3 mbps before dropping right back down. I tested a file on megaupload and it seems to bounce between 50kbps and 1.5mbps nonstop.
The driver i believe is the iwl3945 if that is the default driver. I have tried disabling ipv6 and that didnt seem to change anything. I've looked around on google and the forums and havent been able to find anything on how to fix this.
Folks, I am running 10.10 with the Macbuntu addon (theming, if that makes a difference).I've noticed for a long time, when I play some videos, my network connection (on this computer only) drops. For instance, while posting this, I began to watch this video:
HTML Code: <iframe id="tsFrame55086" src="http://cdn.topspin.net/api/v2/widget/player/55086" style="width:400px;height:300px;border:none;" frameborder="0"/>
At my workplace the wireless connection is open but once you connect you first need to authenticate on your browser to be able to use the internet.On Windows as soon as I open whatever page I get the login request.On Linux I open firefox but nothing happens, just get the usual error page like if I had no connection. The IP's I get as well as DNS seem ok, I even tryed to match them up with windows.I tried a lot but can't get to the login page.
specific Ubuntu supported WLAN PCI-cards? This link shows a list of supported PCI-cards, but which is best: [URL] And the installation needs to be easy! I�ve tried installing these PCI-cards in my computer, useing Linux drivers, NdisWrapper, etc. Unforutately without any success:
- DWL-G510, Ralink Chipset, Ralink RT2561/RT61
- Realtek Semiconductor, RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller
Today I upgraded from 10.10 to 11.04. After accidentally turning off the computer during the upgrade, booting into recovery mode, remounting the file system as writable and finishing the upgrade, it worked just fine.
However, I can no longer use any wireless networks. Wired ethernet works fine, but the wireless inteface won't even show up when I run ifconfig. When I first installed 10.10, it worked instantly and I was able to use it during installation.
I have an HP Compaq nx7300 laptop with a Broadcom BCM4311 network card.
I installed 11.04 to ASUS Z9200 Notebook, at first all was fine at least 10 minutes, LAN, WLAN worked ok, but suddenly all is gone, restarted few times -nothing. reintall-nothing...here is some info....any ideas?
As soon as I add "iptables -A OUTPUT -j DROP" server lock me out and I have to reboot to be able log back. The ssh port is open in both INPUT and OUTPUT what's wrong?
I have a sh-tty B/G wireless card that does 500mw according to iwconfig. I also have a nice little panel antenna on this card that does 7dBi. This rig picks up a lot of signals and that is really great. However I am experiencing a problem. I am able to Internet browse on non-encrypted networks as long as the wireless manager shows a full four bars. However, if I try to connect to a three bar network, I will not be able to browse the Internet. I have a solid lower level 3 bars, I'm assigned an IP addy, but I get absolutely no throughput.
So, I think this has something to do with receiver sensitivity. In G mode, this card does a lousy -65ish or so at 54 meg. So what I'd like to do is drop to 5.5 or 11 meg B because at 5.5 meg or 11 meg B, the card does a much more acceptable 90+ sensitivity.Does anyone have the command string/app for this? I would like to force a card to operate in no better than 802.11B@5.5meg rather than having it auto select 802.11G@54meg.
I have (had?) ndiswrapper-dkms installed, and used it to get a wireless card working. After a kernel update, the card stopped working, and I tried to re-install it. Part of the directions included doing -r to about everything connected to the original install. Now I still show "Windows Wireless Drivers" in the drop-down menu, but when I click on it, it "flashes" for a split-second, and then disappears.'ve tried re-installing it from Synaptic, and doing "sudo apt-get install ndiswrapper-dkms" but it just returns saying that I already have the latest version.
I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.
I have bought a new laptop with win7 on it , I delete win7 and install ubuntu64 everything is ok but my wireless card won't work ( it is recognized) and even I can connect to INTERNET but nothing is download or upload so I have bought another usb wireless card but now when I connect this new card to my laptop it still tries to use the old one and so I could not connect to internet
I am trying to connect to a WEP encrypted WLAN without using the DHCP server of the AP. (=giving myself a static IP)
So far i have tried:
Code:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?
I can connect my wlan card to router (gateway) ,but I can't go to internet, pinging my router (and everything else) also falied. Same problem was with knoppix but with help of others i solved it modifing etc/reslove.conf IP address to my gateway (nameserver). At ubuntu resolve.conf seems ok, as there is already IP address of my gateway?
All I want to do is share my internet connection that comes through the eth0 cable to my wlan0 wiki card. Firestarter seems the convenient tool for doing this. BUT it keeps telling me wlan0 not ready. The card is connected correctly and network-manager does see incoming signals.
I'm a new user of Ubuntu and I think I need some help but let me mention before that I got this up working on a Debian system.My current kernel version is $ uname -r 2.6.32-27-generic.The problem is that my wlan card is not working any more such that my system freezes every time I enable networking with the hardware switch on my laptop.Therefore I bought a USB - WLAN stick and try to get this working.
Network Manager has the option "enable wireless" greyed out if I disable the hardware switch.If I enable the hardware switch and remove the module of my wlan CARD before (modprobe -r iwl3945) it says "wireless disconnected" for all networks.
anybody out there with an idea for a command to make the WLAN-Printer (HP-Officejet)work again when it stops after 30 Min - 2 h.Simple stopping the print job and print again does not help. The only way for me is to stop the print job and RESTART. Then it works again 30 Min- 2 h. I use updatet lucid lynx 32.
And I need a command like "killall pulseaudio" that I need when I return from logged-on as the second user to get sound again.
