Ubuntu Networking :: Wireless Keeps Dropping At School

Oct 5, 2010

I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).

However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?

Ubuntu Networking :: Can't Connect To School Wireless

Jan 4, 2010

I installed Ubuntu 9.10 onto my laptop, and having wireless issue. I was able to connect to wireless at home, but cannot at school. Then recently, I reformatted by desktop at home, and now I can no longer connect to my own connection. But yet, I'm able to connect to my neighbor. I considered installing ndisgtk package, but then i thought if I'm able to connect to some connections that means I'm not missing windows driver (maybe I'm wrong ).

Ubuntu Networking :: Wireless Connection Not Working In School

May 5, 2010

I am using Ubuntu 10.04 LTS - Lucid Lynx(great interface!). But I am experiencing a very weird problem. The wireless internet works just fine at my apartment. But when I am in my school, it just stops working at all. It didn't use to be like that. It used to work in school too few weeks before. But I don't know what happened all of a sudden. I have checked with my school system administrator to know if there has been any change with the network. He said the network has always been the same.

Ubuntu Networking :: Wireless Internet Dropping Out?

Feb 17, 2010

This is weird. I will be working on the internet with several tabs open and all of a sudden the pages won't update. I can't go anywhere - it's like I lost the connection. I am also downloading bittorrents with uTorrent running with WIne and that doesn't seem to be affected. I also have gPodder and I tried to update podcasts with that and it also hangs up as if it can't connect. The only way I have been able to solve this has been to reboot (which I just did).

Ubuntu Networking :: Wireless Dropping But Not Windows?

Feb 25, 2010

Having major wireless issues with Linux. I have DSL and had a Westell router/modem combo and my wireless would stay up for no more than 15 mins at a time even while idle, and in order to get wireless back I have to reboot and then I can get another 5-15 mins of wireless before it drops. When it drops it prompts me for my wep key and wont accept it yet if I reboot it catches the wireless right away for a very short period. So I go out today and spend over $100 bucks on a Netgear dgn2000 thinking it would fix the problem... Nope I am still in the same boat as I was with the Westell.

I am not seeing my router model listed under the wiki link sticky.. (Edit) thought I installed ndiswrapper, it was it was in my downloads anyway I can't install it I get the following error (Not a valid driver .inf file.)I have tried 3 distros and have the same problem. I went to Netgears site in search of Linux drivers but all I found was the firmware updates. Could some one please shed some light on what I need to do to get up and running?This is a new laptop and I am pretty annoyed with myself for formatting it out of the box rather than reading up a bit more about Linux (been using for one month).I don't understand it Ubuntu 10.9 ran wireless perfect on my older system, (full install) and I have no trouble with my lap top that is running Windows.I really hope to get this resolved I really enjoy Linux and I don't want this to be the one handicap which would force me back to Windows, that would be very upsetting

Ubuntu Networking :: Wireless Won't Reconnect After Dropping?

May 26, 2011

I'm having a problem with the wireless on my Asus EEEPC 1000HE using Ubuntu 110.04. Digging into the laptop forums, it says there is a problem with wireless on some models of the 1000HE, but it is not the same wireless device and my wireless problem doesn't seem as bad as listed, so I think it's a different problem. But my problem is that if wireless drops for any reason, it will not start working again unless I either reboot the computer or click the wireless icon in the systray, click disconnect so it stops flashing (like it's trying to reconnect) and then suspend my computer or log off and back on. And it only does the latter because I added a file located at /etc/pm/config.d/00sleep_module with the one line that reads SUSPEND_MODULES="rt2800pci" (my wireless driver) So that one line seems to cause wireless to get a fresh connection after suspending (or something. I'm not a very advanced LInux user). I've tried running the command "sudo/etc/init.d/networking restart", but that does nothing for me. I'm not sure what other command to try to see if can fix it.[URL]

Ubuntu Networking :: WiFi Dropping And Dropping Speed

Feb 25, 2010

As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.

To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

OS: Ubuntu Server 9.10 + desktop installed

Ubuntu Networking :: Thinkpad W500 Wireless Connection Keeps Dropping

Oct 27, 2010

I have a Thinkpad W500 with:

Code:
Network controller: Intel Corporation Wireless WiFi Link 5300
I have Ubuntu 10.04 32bit installed:

Code:
Linux dani-laptop 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC 2010 i686 GNU/Linux

It has been working fine since I installed 10.04 but recently (end of last week I think) it stared dropping the wireless connection very often. So it will disconnect and reconnect, but I can't seem to find a pattern, sometimes it goes for hours without an issue and sometimes it does it several times in a row. Below is an extract of syslogs from when this happens. But not sure if what I need is there... the only weird thing I can see is:

Code:
Oct 27 18:58:33 username-laptop wpa_supplicant[1296]: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

Ubuntu Networking :: Losing (dropping) Wireless Connection After Changing MAC Addr?

Aug 8, 2011

Sorry if this has already been solved;answered anywhere else - I tried looking it up but to no avail. The problem persists & the hints I found around the forum did not provide a solution to the case, neither other net solutions i looked up I run Winblows at the lab and sometimes take my Ubuntu PC with me. There is an open Wireless network where they set MAC permission, and there's no pwd to access. It so should be fairly easy to change m MAC and access it, right! No. I run ifconfig and macchange, successfully change my MAC addr BUT the connection drops! Then if I change it back (MAC to my original address) it goes back online. And yes, I shut down the service -- "ifconfig wlan0 down" and then up..WHAT ON EARTH am I doing wrong??? No webpages touch this 'trouble-frigging-shooting instance!

Debian Configuration :: Can't Connect To Wireless Networks At School

Mar 10, 2011

I installed Debian sid recently. I installed the B43 driver and wireless is working just fine at home and elsewhere. I can't connect to the wireless networks at school though. There are two networks, one is unsecured (and you have to enter your login details after connecting - I can't connect at all though), the other is secured. I was previously using Ubuntu, with network manager, and I have all my settings the same for the secured network as I did in Ubuntu. In Ubuntu I can connect to both networks just fine. In Debian I can't.

Ubuntu Networking :: Tunneling Through School AP

Mar 14, 2011

I am trying to tunnel through my college's free AP so I can get access to protocols outside of http and https. The school has an in-browser DNS redirect until you log in.The output of "cat /proc/version" on the server OS is "Linux version 2.6.35-27-generic (buildd@palmer) (gcc version 4.4.5 (Ubuntu/Linar o 4.4.4-14ubuntu5) ) #48-Ubuntu SMP Tue Feb 22 20:25:29 UTC 2011" The client OS is Windows 7. What I have done so far is use Proxy Cap to redirect applications to a Putty tunnel connected to the server. Eventually I want to tunnel that SSH connection through my school's firewall, so that I can keep encryption and have a reasonable amount of ease with setup.

I am not particularly educated on the inner workings of the DNS redirecting so I was not sure what to search for. My attempts to connect Firefox over normal http proxies failed and since all ports are blocked besides http and https I didn't attempt any socks or SSH. I have also tried simply hosting the SSH server on http ports with little success. I hope that I can do this without having to purchase a domain, but that's starting to seem like that won't be the case.

Ubuntu Networking :: Map To School Share Network?

Feb 1, 2011

I am trying to map to my schools shares VIA their network.

Normally on windows, I would just say Run and type the network path and it would open a window with the folders.

the path is \KNA11.XX.ON.CA you need to be on our VPN to connect to it, which I am.

How do i access this directory in ubuntu? And even better, make it a permanent shortcut or mountpoint so that i can easily access it later without having to re-mount it.

Ubuntu Networking :: Cannot Connect To School WiFi - Need Certificate

Oct 28, 2010

At home, I can easily connect to my home network with ubuntu. But at school, things are differently. The wireless security is tighter, and I need more then just my username and password to connect.
(See attachment for Screenshot)
The last two lines, okay, but I seem to need a certificate, and that MSCHAPv2, Anonimous identity. I don't understand what I need to enter in those fields. I only got a username and password from school and that's all I need for windows. So why does Ubuntu want/need more info?

I was having trouble with my wireless connection, it was dropping every 5 minutes or so after upgrading to 10.04 and ran across a thread where someone recommended entering

OpenSUSE Wireless :: Connection Dropping On Both Laptops With 11.3

Feb 8, 2011

I'm using an Acer Aspire 3000 since Opensuse 9.3. Wireless connection was fine with ndiswrapper. I upgraded to 10.0 and wireless was perfect with the broadcom firmware. Now I just installed openSUSE 11.3 and my wireless connection became a nightmare: connection drops multiple times in a day and network manager remains stuck in "Interface Configuration". Sometimes I'm asked for the wpa password but Network Manager is unable to reconnect until I disable and re-enable my wlan card using the killswitch. The access point is the same zyxel b+g I own since 5 years! I just bought a new eeepc and I installed on it openSUSE 11.3 too. The network connection behaves the same!! The Network Manager says "Interface configuration" and I must switch the wireless off and on to have the network back. I made a radio scan and I'm using a channel on my own. I also tried to disable dhcp without success.

Ubuntu :: Hardy Heron Kept Dropping Network Connection (both Wired And Wireless)?

Apr 30, 2010

using Hardy Heron on a old Thinkpad T41.This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time.
fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..

OpenSUSE Wireless :: Dropping Connection After Unspecified Time

Mar 21, 2010

Toshiba A215 laptop
Driver is rtl8187
I really need to make the connection constant and non-dropping. I've had opensuse 11.2 since march 7 2010, figured out most of it by lurking and reading threads didn't want to make threads but I really don't know what to do to make this connection stay on. I am posting Terminal commands from when I am both on and offline.

How I attempted to fix this issue myself: I downloaded wireshark, wicd,knetworkmanager. Tried running all of them nothing worked. I went into Yast and switched off networkmanager and went traditional still nothing. Tried adding opendns to traditional. nothing. Went back to NM would get online then after an unknown time I'd lose connection even though NM said i was still connected. Offline running terminal commands from what I read on here in other threads and stickies
