Ubuntu Networking :: Wireless Drops In An Out (9.10)

Jan 14, 2010

I am running Ubuntu 9.10 on a Dell Inspiron E1505 and I am having problems with my wireless. It is a Broadcom B43xx series wireless card. I have the restricted drivers installed but I have trouble with it maintaining a constant connection. I attend a college where in order to connect to the wi-fi you need to have their certificates installed.The wireless certificates are installed and I'm telling Ubuntu to use it in order to connect but it drops in and out. I will be connected for a minute or two but then it will randomly drop out on me. I know its not my wireless hardware because any other wireless that I connect to off campus works perfectly fine. Any ideas on how to get this to work correctly?

I hate to bring this OS up but my Windows 7 connects perfectly. (On the same laptop. I triple boot: Ubuntu, Windows 7 [gaming OS] and Backtrack4 )If it helps any the wireless AP uses WPA2-Enterprise, PEAP, and MSCHAPv2 authentication, and the CA certificate (which I have selected to use), plus my user name and password.

Ubuntu Networking :: 10.04 Wireless Drops Intermittently

Jun 22, 2010

i have an asus eeepc that i recently upgraded from ubuntu 9.10 to 10.04. the wireless networking has worked great up until about 2 weeks ago. now it occasionally drops the connection (can't ping the gateway), even though the "blue bars" still say connected. my current solution is to click the bars, do a "disconnect", and then reconnect.i've ruled out the router being a problem (all 17 other wireless devices in my house remain connected), and i've ruled out a laptop hardware problem (when i dual boot into win7, i never lose my connection).

i'm new to linux (installed 9.10 back in february), but not new to computers/networking. i run a major campus lan [windows based] and have worked all aspects from the early mainframe days to client support to server admin to helpdesk - after 17 years, i'm now in management, so i've lost my edge a little... plus, being brand new to linux, i'm feeling a little lost in the troubleshooting aspect of this.i do believe that i've narrowed my problem down to "almost exactly" when this occurs. the wireless connection drops out as soon as i start to do "network intensive" stuff like watch a videos video, play a facebook flash game, or (and here's the kicker), try to run the update manager. unfortunately, this means that i have not been able to update for a few weeks now. i'm up to about 150mb worth of updates that are waiting.

Ubuntu Networking :: Wireless Constantly Drops Out?

Sep 15, 2010

I have been running Ubuntu for 2 years and have not had a problem like this. Randomly one day my wireless dropped out. I can see other networks on my laptop, but they are all locked so i cant test and see if i can connect to them so i went to my friends house and was connect fine for over an hour.

Also my PS3 and my windows box connect to my router and internet just fine.

I then assumed that this was a hardware issue then with my wireless card on my laptop. So i called up lenovo and they sent me a new wireless card. I installed it and still had the same problem.

Lenovo t400
Intel 5300 Wireless
Ubuntu 10.4
Router
Dlink-655

I realixe i am not giving to much information, let me know what you need and i will provide it.

I tried buying a new router now and it worked great!!!..... for an hour. Now it is doing the same thing.

Ubuntu Networking :: Wireless Still Drops Atheros AR9285

Mar 30, 2010

I bought this new computer with an Atheros AR9285 wireless adapter, signal dropped out after a couple of minutes, sometimes reconnected, I looked up different posts on [URL] and [URL].

First I installed linux-backports and linux-backports-wireless, still dropped. Then I installed compat-wireless-2.6.33 and it still dropped. Finalley I blacklisted the driver with gksu gedit /etc/modprobe.d/blacklist-ath_pci.conf and it still drops. What should I do, it seems to pick it up again after 30 sec or so, but it a bit frustrating.

P.S.: It seems to be getting much better now that I have the torrent program shut down.

Ubuntu Networking :: Wireless Drops Occassionally / Why This Is Happening?

Sep 2, 2010

I'm running 9.10 on a desktop that connects to my network using a PCMCIA wifi card plugged into a PCI cardbus adapter. Sometimes, (it seems to be when too much data has gone over the card), I lose connectivity. nm-applet still shows me connected but I can't even get to my router (ping or gui). I use ndiswrapper for the driver.

If I unplug the PCMCIA card and then plug it back in I get going again. My questions are:

1) Anyone have an idea why this might be happening?

2) Is there a way in software for me to unload and reload the wifi card?

Ubuntu Networking :: Wireless Connection Drops Out After 15 Minutes?

Jun 13, 2011

Having struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!

Ubuntu Networking :: Wireless Connection Drops When Screen Locks?

Jan 22, 2011

I just got a wireless dongle because in my house wired is not possible, but now I am getting problems. The dongle is a tp-link that turned out to be plug&play (unlike windows) and seems to work perfectly, except when the screen locks. I have tried to download overnight several times and it seems like a few minutes after the screensaver comes on or after I lock the screen, the connection is dropped. It works completely fine normally. So what changes when Ubuntu (its maverick with all updates) locks the screen? Also, when I log back in, I have to unplug the dongle and plug it back in to get it to connect again.

This is really REALLY annoying, enough to make me switch back to windows if I can only download while I'm looking at the screen.

Ubuntu Networking :: Wireless Connection Regularly Drops With Torrents

Apr 24, 2011

My wireless connection drops after a while when downloading torrents. I have to reconnect manually. Current configuration is Macbook Pro 5.5 with Broadcom card and Lucid. I've tried with Transmission and KTorrent. It's not a network problem as my Win laptop works smoothly and with higher transfers rates (i.e. 1MB/s in Win vs. 300KB/s at most in Ubuntu).

Ubuntu Networking :: Wireless Connection Drops - Access Point Not Assigned

Aug 19, 2010

I have Ubuntu command line only installed on my HTPC (it is XBMC Live installation). Kernel is 2.6.31-16-generic. My wi-fi card is AW-NE770 from AzureWave (mini-pci on Zotac Atom motherboard). I have successfully configured wireless connection to my router. Unfortunately, after short period of time connection drops. When I restart /etc/network/interfaces all goes back to normal. When connection is dropped, iwconfig shows that access point is not assigned. I have already tried installing backport drivers, removing security on the network (WEP and WPA), assigning static IP or using DHCP. Nothing works. I know it is not the router or my internet because I can be at the same time on my laptop and that works fine.

Ubuntu Networking :: Wireless Repeatedly Drops After 10.10 Upgrade - Broadcom 4309

Oct 23, 2010

My wireless connection ran without issue when I ran Ubuntu 9.x on a windows dual boot loader. Liking Ubuntu, I wiped the system and installed a 10.10 with no dual boot. After the upgrade, my wireless connection is no longer reliable.

Wireless seems to stay connected when traffic volumes are low. As soon as any significant traffic is generated such as a download, torrent or video stream, the network disconnects. Disabling and re-enabling the connection at the GUI recovers the connection. Disconnect can be generated on demand.

If I can somehow roll back to the 9.x network setup I was running. Unclear to me (n00b) if the windows dual boot was impacting that setup or not.

Ubuntu Networking :: On Laptop (Samsung R580) Wireless Connection Drops Out

Nov 22, 2010

I've recently installed ubuntu 10.10 32 bit on an external HDD in order to use it as a portable operating system. An issue I have is when running on my laptop (Samsung R580) the wireless connection drops out however the nm-applet still shows it's connected. If I disconnect and reconnect it keeps asking for the access password. The wireless card on the laptop is the RTL8192E (not SE!). I have used the install on a couple of other machines with different wireless cards and no problems. Linux Kernel version is 2.6.35-22-generic. I have searched around and see that the drivers are in early development. If I tried installing the windows driver via ndiswrapper would this affect the portability of the operating system?

Ubuntu Networking :: Dell 1545 - Wireless Connection Drops After A Couple Of Minutes?

Apr 10, 2010

I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.

I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.

Ubuntu Networking :: Wireless Internet Drops Frequently With Realtek Card On Kubuntu 10.04?

Feb 11, 2011

I'm using Kubuntu 10.04.2 LTS on a Bangho laptop. Kernel 2.6.32-28-generic i686. My card is: Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter iwconfig wlan0 gives me:

Code:
wlan0 IEEE 802.11bg ESSID:"Default_WLAN"
Mode:Managed Frequency:2.442 GHz Access Point: 00:06:4F:8D:B9:AF
Bit Rate=1 Mb/s Tx-Power=20 dBm
Retry long limit:7 RTS thr: off Fragment thr: off

[Code]...

Usually when this happens, for 10 or 20 seconds it appears to be connected (i.e. the heart symbol is there) but I can't ping google or my router, then it "realizes" it's disconnected. It takes one or two attempts to reconnect successfully by pressing the "active" button. Meanwhile throughout the disconnections and re-connections the signal is very strong (98%).

I had the same problem with my old access point, at first I thought it was the cheap/old hardware, so now I bought an "ENCORE ENDSL-A2+WIGX2 | ADSL 2+ Modem with 4 Port Wireless Router". The problem persists only with a stronger signal.

OpenSUSE Wireless :: Wireless Drops Out When Running On Battery?

Feb 27, 2010

I just got a Lenovo Thinkpad x100e. Everything seems to be running well, with this exception of the wireless adapter. When running on the battery the wireless runs for about 30secs to 1 minute before dropping out. The NetworkManager says it's still connected, but nothing goes across the network. Disabling and then re-enabling the wireless works, for about 30 sec to a minute. The weird thing is this behavior DOESN'T occur when the power adapter is plugged in.

I'm wondering what power management parts I should be looking at? I'm running OpenSuSE 11.2, KDE 4.3.5 if that helps.

Slackware :: Wireless Drops Out All The Time In 13.37

May 11, 2011

I did a fresh install of Slackware 13.37, and everything is great, and thanks to Pat and the team.

Recently I notice that Wireless drops out all the times, and it will show low connection first, then basically drops.

Is there anything I forgot to do?

For me, I normally have two ways to bring up wireless, sometime I use WICD, sometimes I just use "ifconfig....iwconfig...dhcpcd eth1"

btw, if I log in WindowsXP, wireless never or seldom drops.

Ubuntu :: Wireless Randomly Drops Connection And Refuses To Reconnect?

Mar 23, 2010

my wireless will connect to a well known connection but will sometimes drop the connection then tries to reconnect. Sometimes it will reconnect w/o a problem but most times it will fail and when it fails it will refuse to even recognize that same wireless connection.

If by a small chance it does recognize the network then when you click on it, it will ask you again for the password, which is already saved onto the computer. After entering the password it will try to reconnect, then fail.

Only solution is to reboot.

I was wondering if there was an easy temporary fix of just reloading the software that controls the wireless.Such as, my audio doesn't work when I boot. I need to reload the ALSA driver using sudo /sbin/alsa force-reload

Is there something specific to the wireless that I can force-reload and it will start working w/o having me reboot my PC?

Software :: Wicd Drops Wireless Connection When Not Actively Being Used?

Jun 16, 2011

This is a little problem I've been having. My internet connection right now is just my rooted android phone broadcasting a wifi signal. It works like a regular wifi connection. When I connect to it, it works fine. But if it goes for more than a minute without having any data transferred, it drops the connection til I reconnect. I can have it downloading all night and it wont go out once. But soon as I let it alone without any data xfer, its down.

My quick fix is to just keep it pinging [URL] and that mostly keeps the connection going (although it still drops occasionally). Anyone know a more permanent solution?

running Slackware64 13.37 with multilib, and wicd 1.7.0

OpenSUSE Wireless :: Iwl3945 Intermittent Drops With Network Manager?

Jul 20, 2010

Installed openSUSE 11.3 over an existing 'very stable' 11.2 installation and started experiencing wireless connectivity issues immediately. Network Manager would show connected 100% - 92% but I would lose connectivity to mail, browser and messenger(s). This disconnect would last less than 30 secs but would occur every 2 to 4 minutes.

dmesg reported:

[ 3663.672098] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 [1]
[ 3664.101085] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 [1]
[ 3664.529050] iwl3945 0000:03:00.0: Failed to get channel info for channel 3 [1]

BTW Channel 3 is the channel my wifi is broadcasting on. I've tried other channels and other computers and it is only openSUSE 11.3 having an issue. I am also using WPA2. Modifying the Global Options in Network Settings from User Controlled with NetworkManager to Traditional Method with ifup seemed to stabilize most of the issues, but I do notice occasional drops. I've also switched from Network Manager to wicd to provide some UI while dealing with this issue. Since iwl3945 drivers are now in the kernel I don't know if I should try to revert to an older driver or if there is another issue.

Ubuntu Networking :: Internet Drops Out For Firefox

Jan 7, 2010

We have three computers at home. I have the only one running Linux, the other two are running Windows XP and using Belkin Wireless G USB Adapters. I started using Linux around November, and used a powerline ethernet cable. (It consists of two parts. One part you plug into your router and the power socket beside it, and the other you plug into your computer and the power socket beside that. It then uses the power lines as a network, and acts like a normal ethernet cable. I used the 'Auto eth0' connection without much problem). Back then, my internet would stop working once every few hours but only for firefox. Other programs such as bittorrent and Spotify continued working.

However, since I got back from holiday a few days ago the situation's worse. The internet regularly pauses (every few minutes, including spotify and msn) for about 30 seconds, and then comes back. Downloads are not cancelled, as they are when I am disconnecting from the internet, they merely seem to pause. The other two computers in our house don't have this problem, and I have tried the wireless adapter, yet it seems to pause at the same times as the wired connection. I know that it too used to work back in November.

Ubuntu Networking :: Server 9.10 Lan Connection Drops ?

Jan 23, 2010

I got a new low power file server (Atom 330 with ion), but didn't enjoy it since.

I installed Ubuntu server 9.10 64bit.

I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan).

Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut.

I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem.

I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down.

When this drop occurs, I have to wait 2 minutes until I can ssh back into the server.

I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes.

Ubuntu Networking :: Improved Speed Now Net Drops A Lot?

Apr 8, 2010

I was having terribly slow internet speed with my wireless setup. I followed someone's advice and now my internet speed is flying. However, now I lose connection a lot - almost once every few minutes. Is there any reason for the changes listed below to make me lose connection so easily?

SETUP:

Ubuntu 910 - 64Bit
Wireless Router: WRT160N
Wireless Card: PCI Asus PCE N13

Changes that improved speed, but killed stability:

Radio Band frequency should be 20 MHZ,
standard channel change to 11
advanced wireless settings should be Beacon Interval 2306
Rts thres = 2307
Disable the Security easy setup*option.
Uncheck the Block Anonymous Internet Requests & reduce the MTU size to* 1400

Ubuntu Networking :: Wired Connection: WAN Drops But LAN OK

Aug 17, 2010

I've had a computer running Ubuntu connected to my TV for a few weeks now, but as of yesterday, I can't get it to keep a connection to the Internet. Everything works well for an hour or so after a reboot, but then no WAN connections work. When this happens, no sites load in Firefox or Chrome, I can't ping Google, I can't SSH to the box from work, and none of the pages I have running on apache load from remote computers. However, all local area connections seem to work fine. SSH from within my LAN takes much longer than usual, but it does still connect.

Networking :: Internet Connectivity Drops With Ubuntu 10.10

Jan 23, 2011

I had my desktop running ubuntu 10.10 at my sisters house hooked up to a router sharing internet with her boyfriend never had a problem with it there. I moved into my own apartment this week plugged the cable modem directly into the broadcom ethernet card and couldn't get an ip or anything it wouldn't connect period so I ended up hooking it up usb which works but only at speeds of 5-7mbit when I have 15mbit connection. So I put another ethernet card in hoping it was just problem with the card and tried it that worked.

I got a connection but it was incredibly slow like getting maybe 5k a second so I open network tools in administration menu and start pinging google. While I'm waiting on a bandwidth test to complete and it takes off getting like 20mbit keeps that connection for a while then out of nowhere just drops to almost nothing. Again for a few minutes then falls off completely so I restart and it does the exact same thing starts off slow then something clicks and it works great for 5 min then nothing?

Ubuntu Networking :: XP Drops Connection To Samba Server

Apr 7, 2010

In order to get my shares working I first have to connect to the windows shares from the Ubuntu machine. Then I can connect to the Samba shares from the windows machine. If I don't continue to use the shares. It'll drop the connection and I have to unmount the windows shares and start the process over. The wireless network still shows as being connected but I get an error on the windows machine if I try to connect. I've Googled this and it appears to be a Windows problem. I know this is a ubuntu forum but thought I'd ask for any info. I believe that this is also what is giving me shared printer issues as well.

Ubuntu Networking :: Wifi Connection Drops On Laptop?

May 1, 2010

I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.

I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.

There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

Ubuntu Networking :: Connection Drops Randomly For A Split Second

Jun 5, 2010

I could not find a solution to this problem anywhere. I use a ubuntu server to play (stream) mp3s and movies to other computers on my network. It works most of the time, but sometimes in the middle of a movie or a song it will drop/hiccup--saying it is "not reachable". I am not overtasking the server at all, and merely playing an mp3 that takes up less than 10% of the bandwidth, yet it drops it for a split second.

I have a WRT160N router (DD-WRT of course) with 4 clients connected (2 of which are wired). The ubuntu server is connected via ethernet and all machines have the same issue. It can't be the router because another Windows machine works just fine for streaming these files. I just can't understand how it can lose connection for a second or so. It may just be the file-system or some service that is hiccuping, but I have no idea...
