Ubuntu Networking :: 10.10 Wireless Unstable-ar2413

Jan 4, 2011

A fresh Xubuntu 10.10 install will give me access to my network, but with fluctuating speeds, and certain pages load forever. I have tried the blacklist edit as well as ndiswrapper, and neither have helped me. I can't find a madwifi guide for this issue either. Details: Upon fresh install of xubuntu 10.10, wireless is detected. I enter my, key, hit google, and all is good. Then I try to log into my online classes. Firefox hung forever. So I tried a few other sites, and to my disappointment, random sites seemed to fail. Brand-new, fresh, clean Xubuntu 10.10 install, Toshiba Satellite M45-165.

Fedora Networking :: Atheros AR2413 FC10 - D-Link Wireless Adapter Worked Fine With Network Manager Disabled

Mar 3, 2009

I have been running FC8 on this IBM T23 with a D-Link wireless adapter. Using MadWifi this has worked fine with Network Manager disabled. But now I have nuked that installation and replaced it with FC10. Network Manager is nice, and I would like to use it. And it kind-of works. Network Manager recognizes my router and all my neighbor's routers, but I can't connect.

Fedora Networking :: Unstable Wireless Connection With Broadcom Onboard Wireless?

Dec 21, 2010

I am running FC13 on a Compaq Presario 2100 using a Broadcom BCM4306. I was able to get it running thanks to Fedora Unity Project. But It's a very unstable connection. I don't know what settings to adjust or enable or disable. It's not my router, this is the only wireless connection in the house that I have trouble with.

Fedora :: Wireless On Sandy Bridge With Atheros AR2413

Apr 7, 2011

I'm in the process of switching back to Fedora after years of hiatus, but I can't get my wireless card working. The card itself is an Atheros AR2413, and the problem is that it seems to appear OK in various places, BUT it doesn't detect any networks. I'm on Fedora 14.

Here are some commands:

Ubuntu Networking :: Weak/unstable Wireless Connection?

May 24, 2010

I understand that wireless is one of the most common problems with Linux, although I did not have this experience with past distributions or versions. After two years away from Ubuntu I installed 10.04 and everything is working fine except the wireless connection. Actually, it does work and connect, but goes up and down, loses connection and in most cases does not reconnect, unless I am 1 meter from the router. The room next door is already too far, a place where I normally have my laptop connecting perfectly with XP.

I am using a Toshiba M70,some additional information below:

lspci=

Ubuntu Networking :: Unstable Wireless Connection On Natty 11.04

May 19, 2011

I'm using an Atheros ath9k wireless card that has been pretty stable since Ubuntu 9.04. I did a clean install of Natty and ever since my wireless connection has been pretty unstable.

It doesn't actually disconnects but I lose all connectivity. The wifi card continues loaded with a static IP Address assigned to it but I cannot connect to anything. The only way to fix it is restating the network manager and I have to do it at least a couple of times every day.

I tried to whitelist ath_pci on /etc/modprobe.d/blacklist-ath_pci.conf but the problem still persists. Also yesterday I enabled the ubuntu backports on my software sources but so far no kernel updates.

Here are some of the messages filling up the logs:

I added all this info to this bug as well: [url]

Ubuntu Networking :: Unstable Realtek 8192 Wireless Driver

Aug 9, 2010

I'm having trouble with my Samsung Netbook N220 and its Realtek 8192 wireless card and could use some help with diagnostics. I would like to use the netbook as a server and after a day or so the system stops responding. What I'd like to know:

- What do the "========>ieee80211_parse_info_param(): athros AP is exist" spam messages actually say? Does anyone else have this and stability problems?

- Why is the realtek driver package not working?

I'm running Ubuntu Netbook 10.04/Kernel 2.6.32-24-generic. Initially the card was unable to connect, so I installed the Realtek driver rtl8192se_linux_2.6.0017.0507.2010 which adds a kernel module r8192se_pci.ko. At first my system was hanging during bootup. I then restored /lib/modules/2.6.32-24-generic and now the card is connecting but the system is unstable. The 2.6.32-23-generic kernel, modules listed below, still has modules as installed by the realtek driver and is not working. Below the drivers supplied by ubuntu

./2.6.32-24-generic/kernel/ubuntu/rtl8192se/r8192se_pci.ko
./2.6.32-24-generic/kernel/drivers/staging/rtl8192su
./2.6.32-24-generic/kernel/drivers/staging/rtl8192su/r8192s_usb.ko

Ubuntu Networking :: Torrent Downloading In 11.04 Causes Unstable Wireless Transfer

Jul 2, 2011

Every time I download torrents in Ubuntu 11.04 on my desktop, using Transmission or Deluge clients, the wireless transfer speed abruptly drops off, becomes very choppy, and in general doesn't remain stable. It's not only the torrent download that slows down, but it's everything including web surfing, even though I'm not maxing out my connection speed. It's not that I'm getting disconnected from my router, it's just that the wireless transfer speed drops off, becomes intermittent, and never gets back up to full speed.

At first I thought that my ISP was throttling my connection, but this issue doesn't happen with a direct cable connection to my router, nor did it happen when I was running Ubuntu 10.04 before. It also doesn't happen when I'm downloading the exact same torrents over wireless using my netbook running Ubuntu Netbook Remix. This issue ONLY seems to happen when using a bittorrent client while on wireless on Ubuntu 11.04 on my desktop. I can max out my internet connection speed by streaming videos, downloading from FTP, etc. using wireless just fine, and the transfer speed remains stable. This also seems to happen with a couple of different wireless USB adapters (rt73usb or rtl8187 drivers).

Ubuntu Networking :: Upgrade To 10.04 - Wireless Connection Is Unstable - Randomly Disconnect ?

May 2, 2010

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.

Ubuntu Networking :: Atheros AR2413 Not Working After 11.04 Upgrade?

Jun 12, 2011

After upgrading to 11.04 about six weeks ago I've had no sufficient solution to my inability to connect to wireless. Here is a summary of the problem:

After the upgrade, nm is running, and lspci detects my wireless controller (Atheros AR2413 802.11b/g), but nm can only sporadically detect/connect to wireless networks. Essentially what happens is that upon startup, I have to wait (sometimes 5 minutes, sometimes hours) for the computer to "decide" that it wants to detect the networks, at which point I can connect. After this it is fine; it doesn't disconnect after this point, but more often than not it takes so long to start working that I might as well not use the computer.

I've tried "Connect to Hidden Wireless Network", to no avail. I should mention that I also run under the Gnome Classic UI, because Unity is one of the worst UI changes I've ever seen in a version. I've read that Unity causes some problems with NM, but I have no corroborating evidence of this, and the problem persists even without using the Unity UI.

Someone recommended using an older kernel, but the file "menu.lst" doesn't even exist in the /boot/grub folder, so I have no idea how I would do that.

Ubuntu Networking :: Marvell 88E8056 Is Unstable?

Jan 8, 2010

During Karmic betas, my Marvell 88E8056 did not work at all. When Karmic got released, it started working but after December update, become terribly unstable, disconnecting like every 5 minutes. It is integrated on P5Q-E mobo. Luckily, I also have Marvell 88E8001 so I switched and it works. I was thinking that new kernel broke driver, and thought that next update will fix it. But yesterday I needed both NICs, and 88E8056 is still did not work. I am using .31-17 kernel. So I do not know if my NIC died or what? Can someone with same NIC say if it works for him? Does it work in Lucid Alpha 1 ?

Ubuntu Networking :: Unstable Mobile Broadband ?

Mar 6, 2010

I have just switched to Ubuntu from Win 7 RC. So far its been fun, learning to use terminal and all. But I have got a problem now I cannot find a solution to.

I am using 3 Mobile Broadband. The thing just worked - I plugged it in, created a new connection, modified config a little and was happily browsing.

However, it started acting out yesterday. When I boot the system with the modem plugged in, the USB stick is recignised and NetworkManager starts connecting (I have auto connect on). It then shows the "connected" message, and generally appears working fine.

On the other hand, I cannot open a single page in Firefox, it shows the default server not found page.

I used the approach Windows taught me: close, open, retry. I unmount the 3 Mobile Broadband drive, pull the modem out and reconnect it. NetworkManager then does it's job and this time everything works.

I nether had this problem in Win7 or Vista. It looks to me something goes wrong during the booting when the modem is plugged in.

Ubuntu Networking :: 3G USB Modem TechFaith Unstable Workaround

May 2, 2010

I have an USB 3G Modem to access broadband internet.The USB 3G Modem is a flying angel from TechFaith company.The modem works fine under Windows XP. The USB 3G Modem propose a data partition with an automatic installation of its driver and software. When I plug the device to the 9.04 Ubuntu workstation it mounts the data partition, but does not find the 3G modem device. I search the internet to find a solution, and the only working solution I found is the following. However, this solution is not stable, after some minutes the device is dropped (no more ttyUSB). I can not use the same process to enable the device.

Code:

su -
eject /dev/sr1
modprobe -v option
echo "1d09 1026" >/sys/bus/usb-serial/drivers/option1/new_id

[code]....

I used the wizard to configure the braodband access (Brunei/B-mobile). It works for somes minutes, and then the connection drops, the /dev/ttyUSB desappears and I can not redo the process.I have to enter the commands in a root shell, the sudo command will not enable the device. Why it does not works with sudo?

Ubuntu Networking :: Intel 4965AGN Unstable In 10.04 LTS 32Bit

Dec 7, 2010

I'm using a notebook with Intel 4965AGN and connecting to a Linksys WRT320N router. I can connect most of the time but after a while (sometimes a few minutes, sometimes a few hours) I lose connection. The notification icon would not change. I would only find out when I browse or click on a link and it would just get stuck at "Looking for <url>..." My wife's notebook would still be connected to the router even after mine has mysteriously disconnected. But she uses another os.

Networking :: 3G Modem Unstable After Upgrade To Wheezy?

Apr 23, 2011

I recently upgraded from Debian Lenny to wheezy (testing). I use a popular 3G modem, the Huawei E220. In Lenny everything worked fine. I use wvdial to connect and the script from lenny, which worked just fine.Unstable behaviour goes like this:I connect, pppd starts, then, either immediately or after a few seconds, the modem hangs up (pppd errorcode 16). Upon retry a SIM Error is being thrown or the /dev/ttyUSB0 node vanishes. Un/Re-plugging the modem and dialing again results in a working connection (mostly). Is there any possibility finding out why the modem hangs up (because a web research revealed that there are a million possibilities for this behaviour)?

Ubuntu Networking :: Eth0 Unstable - Iptables Empty - Cant Service Iptable Restart

May 13, 2011

This is my first use of Ubuntu, but I have previous decent experience on Centos & Mandriva. I've just installed Natty 11.04 on a box that was running a mandriva 2010 - and the network is acting quite strange. When I define a static IP for eth0 through the gui, along with route & dns, it sort of works: ssh is fine, vnc too. However, I have an asterisk running on the box, and it is wild: some packets get lost in the box.

An ngrep shows the packets reaching the interface, but they dont show in asterisk !!! I've done a ufw disable, iptables is empty (why cant I service iptable restart btw ?). ip route list show decent routes (eth0 default); When I switch to DHCP, it is better, but unstable... If i plug a wifi usb stick, it seems to be better... Is there some known issues that could explain this behaviour ? The nic is a: Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller

Ubuntu Networking :: Wireless - Lost It - 'wmaster0 No Wireless Extensions', But Then Refers To Wlan0 As The Wireless Connection

Mar 28, 2010

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.

Ubuntu :: Clusterssh Unstable KDE 4.3.2?

Feb 2, 2010

In one of the last KDE 4 updates, or perhaps when moving from intrepid to karmic, using the application "clusterssh" has become completely unstable. Some of the symptoms I have experienced:

1. Window focus problems. Clicking on a single xterm window from a group of xterms controlled by clusterssh does not switch focus to that window. Focus stays on the clusterssh application, so output is still directed to all xterms. Previously, I could interact with a single xterm, or with all of them.

2. Clipboard problems. After using clusterssh for awhile, and perhaps using the clipboard within clusterssh cutting and pasting between other applications completely fails. The only work-around is to completely log out of your kde session, hence killing your clusterssh sessions.

3. xterm window manipulation. At some point during a clusterssh session, all xterm windows become locked in place. You can't move them at all. This also leads to focus problems described above. The work-around for this is to switch virtual desktops, and then switch back to your clusterssh session, and now the windows can be manipulated and re-organized again.

Ubuntu :: Vino 2.28.2 Unstable On 10.4?

May 5, 2011

I have a Linux box with Ubuntu 10.4 that I use basically to play music and download files. It doesn't have a monitor or keyboard, the only way I access it is using Ultra VNC. Yesterday, the automatic update service offered to update Vino (among other things) to version 2.28.2 and, as usual, I accepted.

After the update Ultra VNC has had trouble negotiating the protocol with Vino. The only way I got it to work was to force using Tight as the compression method, which provides a crappy image quality. Besides that, at some unexpected moment, the connection just dies.

Can anyone help me to:
1.- Solve this issue with the current Vino version or
2.- Go back to the previous version that was working perfectly.
