I can connect to the wireless at my school, but the connection drops frequently and regularly. Network Manager still shows bars indicating the network strength and shows that it's connected to the network in the dropdown. Selecting the network again causes it to indicate that it disconnects and reconnects. At this point I have wireless until the connection drops again. Possibly relevant details: This is the Purdue PAL2.0 network, which can be tricky to connect to, particularly for Linux users. It's a hidden network using WPA2 and PEAP. My computer is a Dell Inspiron 1420n laptop, circa August 2007.
I recently installed fedora 15 on my computer but I have a huge problem. I can connect to my router wirelessly for a couple of minutes only. Afterwards my computer has no Internet connection although the network manager and the icon on the upper bar says that i am still connected. I tried editing the /etc/rc.local and /etc/resolv.conf as mentioned in other posts in here bit no luck so far.
I just installed Fedora 13 from the Live CD. FIrst off I read the guide and the first step doesn't even work for me. System>Administration>Network does not exist. If I go to System then Preferences I see a Network Manager but it looks nothing like what these screen shots look like. [url]
No wireless card show up in the wireless tab of Network Manager. How can I fix this since my card is listed in ifconfig and iwconfig. Wifi card is a Zonet zew2500p
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
I'm running Ubuntu 9.10 with fluxbox installed. Occasionally my internet connection will stop working, but when I check on wifi radar, I'm still connected to the network. The router is not plugged into a computer at the moment, just the cable jack. It is likely a hardware problem however, since my other laptops also experience disconnects. Any help beyond "change the cable" would be greatly appreciated. For instance, even though I am connected to the network, I cannot post at the moment due to lack of internet connection.
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.
I'm using Scientific Linux on a laptop, connecting to a debian server on my LAN via a basic BT HomeHub router. When starting a file transfer with ftp or rsync from the laptop my connection is dropped, every time, after a couple of seconds. I have to reset my network adaptor and restart my network manager (wicd in this case) in order to get network connectivity back. I had a very similar problem before - [URL]. On this occasion my workaround was to replace NetworkManager with yast. I am now using SL though so no yast available, and I am not using NetworkManager any more anyway.
After connecting my phone via bluetooth using Blueman and then activating Dialup connection in Blueman, it says "Now DUN is available in Network Manager" or something like this. But, there is NOTHING about DUN connection in NM. What this thing is telling about?
i am using mobile broadband to connect with network after i connecting mb.it drops it's connection for every 10 minutes.i need to restart to reconnect it.it is happening in kde.
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
[code]....
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
I just wanted to know what's your opinion on my problem.I have few linux servers that can be located on any place in the world, only port 22 is open. At my office I need connection to every server, but every server must be isolated from every server.So by now I worked only with ssh authorization by username and password. What seems to be preferable ?.
1 Going on working with ssh with authorization. 2 working with ssh but with adding keys 3 start to work with vpn
So if I am keeping use ssh with authorization I need something that will change password every month only for security working with ssh key, it seems like key depends on gateway where key created so if change gateway I lost connection using vpn sounds good but in this case I mush isolate servers from each other.The best solution I think is combination of any two methods
how to change the IP range provided by default by Network Manager / dnsmasq from 10.42.43.-- to something else?
I have setup a working network using a Bell wireless modem (Canada) and Network Manager in 8.10, 9.04, and 9.10.to do Internet connection sharing. In 8.10 the only way I could get it to work was with WICD and KPPP, many hours spent on this one. I got it to work in 9.04 and 9.10 using network manager, but certainly not out-of-the-box. If someone would like some tips on how I did it, in each case, let me know.
My current challenge is trying to set the dhcp range of dnsmasq (which I am 99% sure is what is handing out addresses) from th 10.42.43.-- address range to a 192.168.0.-- range.
I HAVE edited /etc/dnsmasq.conf and can get the edits to this file to break the setup (dnsmasq will not start) but have not been able to get it to change the IP address range.
It seems that either this file is ignored, or overridden by some other process. I have looked at the very good post at [URL] about dnsmasq but this does not do the trick.
By the way, the way I can get this to work is to start NM, establish my cellular internet connection, then kill dnsmasq then establish my ICS network (on eth0). If I don't kill dnsmasq, then it does bring up the connection, but it then shuts down in a matter of seconds. It is all very manageable using a launcher (kdesudo pkill dnsmasq) on the task bar, but not all that elegant.
the IP range and where this is provided to Network Manager or the network itself is my real question now.
I'm running lucid 10.04 on my netbook (regular desktop distro though). I enabled the proprietary drivers needed to get wireless working (I have an hp mini 110 by the way), but the applet in the taskbar will never show a connection, even if it is connected.
- a wired network - a wireless network - a mobile broadband network as both "system connection" and "automatic connection".
I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.
I've read a lot on the internet about various ways of doing this but i've been unsuccessful each time. Basically what i've done is accidently un-installed network-manager because I was having trouble staying connected on my WPA network. The easiest way of reinstalling it I know of is using the CD but I don't have a CD ROM drive and the pen drive I used to install it I no longer have.
I tried using a program called Keryx but you need python installed and from some reason this doesn't come with ubuntu 10.10. I've also downloaded the .deb packages but I still need to download 200kb which is a killer. I've also downloaded it from here too [URL] but the install file makes no sense to me as i'm not a massive linux user. One last thing reinstalling isn't really an option as i've already put a lot of time into setting up this computer.
I'm trying to share internet connection with my wifi capable mobile device. For that I'm creating ad-hoc wifi connection in networkmanager with 'shared to other computers' ipv4 option. And there is the problem - the device cannot get the setting via DHCP. The firewall is adjusted properly by NM, dnsmasq is started. I've looked at dnsmasq arguments string and found that the temporary config file which is provided by NM is empty. So, where else should I look for a possible reason or should I just post a NM bug?
Fresh install of Fedora 14 from Live cd.Used it for an hour or so, d-loaded some programs, had ti all running great. Wired connection to internet. Had the Network Connection Manager icon in panel. There was an icon saying new updates, alot of them, like 400 or so. Told it to go ahead and up date, left room. Came back hour later was done, said it needed to re boot, so I did. From then on, no internet, not icon, no Network Connection in the drop down list for preferences.
What I have tried:Worked off live cd, again, all works fine, icon, manager, internet all there.In installed version: In terminal, typed service Network Manager, it said unrecognized service.Did yum install network manager. It started to do it, but looked like it was trying to get stuff off mirrors, and of course there is no internet access. error PYCURJ ERROR 6.Of course I can re install, but I figure I will just end up in the same place a few hours from now.
I'd like to use NetworkManager on a freshly installed CenntOS 5 on laptop Lenovo ThinkPad T61p. I followed: [URL] Everything went OK, until I selected my active LAN connection in "Edit Connections". After clicking on "Edit", it's not possible to change anything - all is grayed-out. I'm guessing it's a permission problem. But I don't know the internal structure of NetworkManager and what files to look at. I was also expecting that after stopping the network service "Syetem->Admin->Network" would be inactive, but it isn't. Shouldn't the old network manager be uninstalled as well?
I am having problems with my 3 dongle- when I connect it to my netbook it flashes green so it detects a 3G network. However there is nothing in network manager enabling me to choose the mobile broadband so I can't use it. I know there should be an entry "mobile broadband" after the wireless networks listed.
I know the dongle works because I have previously used it successfully- I was using Linux Mint 8 and have now updated to version 9 and when I have tried to use it have been unable to do so.
I have gone into the connections and my 3 connection is present but there is no way for me to select it in network manager.
I have a Ubuntu 10.04 laptop that gets its Internet connection via WIFI using WICD as network manager, and Windows XP desktop with no Internet connection. What I want to do is share my Internet connection from my laptop with my desktop via a Ethernet cable. But i have no idea what to do. How do i go about doing this?
I have installed recently the Fedora 8 in a computer and during installation it was set a static IP with the netmask and gateway. At first it worked well, but after some boots the connection begins to fail. It seems that the network-manager withdraws the static IP and tries to get connection via DHCP. Below is the /var/log/messages file during the failed connection:
Code: Sep 19 10:36:53 canario avahi-daemon[1695]: Interface eth0.IPv4 no longer relevant for mDNS.

I have updated the system this morning and the vpn stopped working!It gives me an error: invalid secrets.I use network manager to connect to a pptp vpn connection, I use fedora 12.Does anyone know the problem?
Just replaced a working install of Ubuntu because i like GS over unity but i cant get my USB760 EVDO card to work. The usual fix of editing the cd.rules file and copying some information into modem.fdi does not seem to work on F15..
Also, noticed that when i attempt to create a broadband connection using network manager it allows me to go through all of the setup dialogs, but never actually adds the broadband connection.
How do I tell the shared connection that it has a static IP and that I dont want a DHCP on the network?Do I have to set up DHCP on the box with the shared connection, even if that box only runs DHCP for a single IP address being the eth0 that is shared?Or can I tell the shared connection that it has a static IP and still allow network manager to run the shared connection?Or should I specify static IP's for all clients and the shared network manager and install say firestarter on the gateway to run the NAT for the eth0 out to eth1.
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.
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.
I have 2 workstations that I'm trying to network together so that I can backup each to the other. One is XP sp2 and the other Fedora 9. Since installing Samba on the Fedora box and trying to get it configured, I have a problem that Add/remove programs won't do installs because it says there's no connection to a network. Network Manager says there aren't any connections, but it worked before the Samba install. Mozilla and Thunderbird can access the internet OK. Both workstations are connected by cable to my router and thus to my ISP (DNS server).
Two questions:- where can I find hints on setting up a wired connection (which card's MAC address does it want? router or wrkstn?) and Am I right that Add/remove is stuffed because of Network Manager?I now have Samba working from Linux to XP, but still can't get into Linux from XP. I tried the Linux PC's MAC address and set up a wired connection in Network Manager. NM still thinks there isn't one...
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.
