Ubuntu Networking :: Lost Connection To Network Printer - Re-establish It?
Feb 12, 2011
I have had long term access to a networked HP Photosmart printer but now I get the following message:
Unable to open device hp:/net/Photosmart_C5100_series?ip=192.168.0.161.
when trying to access it.The ubuntu desktop is wired to the router as is the printer and another iMac wirelessly can still print to the HP. HPLIP status shows the icon for the printer but with a red x indicating no connection to it.The only recent network change was the removal of another router from our network. (service is DSL via a combo modem/router from service provider which previously was connected to a Dlink router which has now been removed from the chain b/c was redundant to the modem/router)
I'm trying to connect to a hidden wireless network in ubuntu through the terminal but i am unable to do so.
I first tried using ifconfig,iwconfig and dhclient initially but i am only able to get an ip address without the default gateway and dns server addresses which i normally get through the network manager applet.
Then i tried using cnetworkmanager but failed miserably again i keep getting this error
Code:
Another applet is running: Bus name already exists: org.freedesktop.NetworkManagerUserSettings (pid 1851)
Then i used nmcli available with the network manager package. i was able to establish a connection only with the connections showed in the list. i use a hidden wireless network. i am unable to connect to the hidden wireless network using nmcli without actually creating a connection from the network manager applet.
I'm new in SUSE 11.4. My problem is: I'm using Alfa AWUS036H card. It's recognised and I can establish connection to my network, but cant get to Internet. I can't surf the web cos Firefox tell me that connection is timed out. Now I'm confused why I can't surf the web even if I'm connected. Also, I trayed to instal linux drivers for this card folloving Ubuntu "how to" and it just dont work.
For strange reasons I was stuck without an Internet connection for about 2 hours. I couldn't establish a connection, even local network only via DHCP. This was on Natty. After 30mins passed, I rebooted to Maverick only to get the same results. With nothing else to do, one hour after, I booted into Windows XP to play Dragon Wars 2. Lo and behold! I had Internet connection. At first I thought it was a technical problem with my ISP. So I rebooted hurriedly to Natty and after several minutes of trying to coax Network Manager for a damn fre*kin* connection it still couldn't.
Back again to XP, I couldn't believe that I wasn't experiencing some kind of on/off signal from my ISP. It wasn't just a coincidence that I could connect on XP and not on Natty. The connection was fine! And I've reason to believe for the past 2 hours, my ISP wasn't the culprit. .. this time it was on my end.Now - on Natty - I manually configured the connection (Instead of DHCP) to be greeted with the familiar Connection Established prompt from notify-OSD.
Since a few days ago, I have too much problems to connect.When I try to connect to Internet with Firefox, the following message is printed out (, most of the times):Code:Unable to connect Firefox can't establish a connection to the server at URL...
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?
I installed ubuntu Karmic Koala 2 weeks ago, and while I have been able to connect to my school wireless, I have not been able to establish a PPPoE connection (username and password).After my most recent try, following this guide:-karmic.htmlMy wireless connection has gone as well.My network manager applet shows my school network, and shows that it is trying to connect, but it cannot establish a connectionand i apologize in advance for any information that i am lacking. please let me know, and i'll try to get the information.I'm running ubuntu on a separate partition, alongside windows XP home.
When there is a power failure at my university for about 30 minute, my computer stays up because of a UPS, but the switch it is connected to via ethernet is reset. After this, my machine loses network connectivity until I manually select the network using nm-applet.
In System -> Preferences -> Network Connections, the network has the "Connect automatically" box checked.
However, in /etc/NetworkManager/nm-system-settings.conf, there is a line that says:
Code: no-auto-default=00:30:48:b0:11:07, and that is the MAC address of the ethernet card.
I had some problems installing 10.04, which I'm not going into here unless I have to, but it appears to be up and running now except my PC can't access the network, even though it's wired. This is the first time I've tried putting on a new build by myself as my son always used to do it (my PC used to belong to him many years ago, and is old, like me.)
t "Failed to Connect Firefox can't establish a connection to the server at127.0.0.1:3580." when I try to open a Help File of one of the applications I have.My /etc/hosts file has its entries right:127.0.0.1 hostname.hostdomain hostnameMy firewall is also disabled.
nmap -sT -O localhost gives me (I have included some): 2401/tcp open cvspserver
I initially loaded Fedora 14 onto a Desktop and started to configure it to be a server but as soon as Iso software updates My network connection completely drops.
I am trying to establish an ssh connection to my server. I have a regular ssh connection working through the command line, so I know my key works and I have the port forwarding on the router correct.
When I go to Places -> Connect to Server the window comes up properly. The only problem is that the drop down menu only has one option in it for Service Type. It is Custom Location. I have had this set up in the past and there were other options there. I chose the ssh connection and everything was fine. Now it doesn't work.
I have tried to completely uninstall nautilus and reinstall it, but that didn't work. When I did uninstall it, I uninstalled gnome-session as well, and I reinstalled that one too.
I am trying to set up, I am having problems understanding what steps I need to take but have done the following on recommendation of help from linux forums but am not getting anywhere with what I have done. PC:
Laptop Dell latitude D610 Ubuntu Gnome 2.26.1
I currently have a wired connection to my laptop but am trying to set up wireless, I have put the antenna on the router and have a wireless network showing called NETGEAR, amongst others, which is my primary router name so i'm trying to connect to that but the actual wireless antenna is on the switching hub. For all intents and purposed assume I am a complete newbie with ubuntu and linux command line stuff, I know basics like pwd, ls and so on but need a good bit of help trying to do this. When I click on this wlan network NETGEAR I get asked for the password, on the bottom of the switching hub is a code for WLAN and I put this in, it then asks for a password for a default keyring, which I do not know. How do I find this out?
But I am still not sure what I am supposed to be doing or looking for to resolve this connection problem, not only am I not a network expert I have no knowledge of linux either and steps to follow to establish a connection.
I'm using Ubuntu for almost two years and everything has worked well till now. One day I have reinstall ubuntu in my computer, but then something went wrong. I couldn't anymore establish my internet connection. I have tried everything but nothing helped. I even reinstall my ubuntu multiple times but there was no efekt. Even when I installed Kubuntu or an older Ubuntu 10.10, there was no internet. I'm also using Windows 7 but there is always a internet connection. I didn't change any hardware on my computer, only a new AMD graphic card. I'm using wired optical Internet 10/10 MB.
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
Dual boot Vista Basic and Ubuntu 10.04 on low spec PC. I can connect to the wireless when I am next to it. I move to the room where the computer is normally used and I lose connection. I can still see it but it fails to establish a connection. Okay, sounds like it's just too far way but when I re-boot and use Vista, it works fine (1 or 2 bars, but it works). Is this a driver issue? Anything I can do apart from move my wireless router?
I am kind of new to linux and have installed the lucid lynx ubuntu distro (10.04) and then "upgraded" it to ubuntu studio but it still says is the lucid lynx. I got a Samsung Q430 laptop with the Atheros AR9285 wireless adapter.I have everything up and running EXCEPT my wireless card. The wireless card DOES work, it does see all the connections available, but when I choose to connect it does not, and keeps asking for the password.
Weird thing is that when I use my samsung galaxy tab as the wireless adapter for its 3G signal, it does seem to work fine (although really slow). I have tried looking for a solution, some say to just install the drivers, but ubuntu does not recognize anything to need a driver except the video card. I have installed linux-backports-modules-wireless-lucid-generic I have also tried the bleeding edge drivers.
After a while of experimenting by myself I came with the following, somewhat rudimentary. I managed to fix the problem by installing the windows wireless driver utility. Here is a tutorial on how to do it. So I just installed it, went to system/administration/windows wireless drivers and just installed it. Downloaded the file from here [URL]. It may not be the best way to fix it, but it does work. Still if you can use ethernet, don't hesitate to do it.
I have tried to mount an HP laser printer on my home network through a VPN IPSES connection from my laptop, but I cannot manage to see the printer or make it accept commands.
My desktop computer, running 11.04 (fresh install) sometimes can't establish a wired Ethernet connection. Sometimes when I boot, it keeps trying to establish, but with no luck. I keep trying to choose "Auto eth0" from the networking menu, but still, it doesn't succeed. If I reboot, it sometimes works. I can't establish a connection about half the times that I boot.
The computer is connected with a cable to a router ("Belkin Wireless Pre-N router"), and the router is connected with a cable to a cable modem.I've been using Ubuntu for a while, and I've had a problem for the past few versions (since around 10.04)? I thought that it might be some old issue that got resolved, so I did a fresh install of 11.04 today, and still have the same behaviorI'm willing to try things next time I can't get a connection, but don't know what.
I have an issue relating my broadband connection, which I am not able to solve. I hope and wish, that I would find some way out here.
Some introduction: I am using Dell Inspiron (i3 processor) laptop, which I recently bought. I have win 7 preinstalled in it. In win 7, the wired broadban connection (Airtel connection) is working fine and have no issues.
I have been using mobile GPRS(BSNL, Ltd) through bluetooth, and that have been working fine. But today when I tried to connect through landline connection, it didn't workout. But the bluetooth connection is still fine. When I tried to do the connection manually through Network Manager, it is not taking the MAC Address. Till now, after installation, I have not updated my OS.
I surfed the net and tried some commands, whose results I am posting below.
From a post I found out, that I should change my duplex settings (from 100 full to 10 full), but I could not get much. The corresponding commands and output,
I installed CentOS 5.5 on my Compaq desktop PC connected to a LAN/Router, at the installation somehow the LAN connection was automatically determined and I was able to use the browser without doing anything.However when I added a print server to the LAN/Router I lost network connection from my Compaq PC running CentOS 5.5. Is there a way to rerun network manager installation to determine the new LAN settings (with a print server attached)
I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result
I am trying to set uamsung clx2160N as a standalone network printer on my home network. It is a printer with standalone network capability and is connected directly to my router and has a static IP number. We have a few Windows computers at home and they had no problem detecting the printer, installing the drivers and working. Unfortunately my Ubuntu computer recognises the printer and I can even access it's setup and diagnositcs through its IP number. However when I try to add it as a printer, drivers for it cannot be located. #ve tried setting it up three ways:1. Using Samsung's own setup package - finds printer and all the details it needs to work but offers no drivers2. Using Ubuntu's printer setup - recognises printer but stalls at Searching for Drivers dialog3. Trying to *** printer using CUPS - no problem finding and recognising printer, but when I come to search for the driver I get Internal Server Error.
I have of course been trying to do all of these as root. That's the limit of my knowledge reached and searches on the net aren't helping me either. The printer works fine directly connected via USB, so the drivers are on the computer somewhere. How do I get them set up to use the printer on the network?
I played with the Network Settings section in YaST, because I wanted to use the wireless network card I installed into the PCI port. OpenSUSE recognised the type of card and its MAC number, and told me that I needed to install a firmware (fwcutter something). I tried some changes on the cable internet connection (like activate on plugged) while I tried to change the wireless connection (like activate on boot).
What I have now is that my cable internet connection is not working at all (it was working just 3 days ago), my wireless internet connection is, as always, not working either. I managed to work the wireless card on Windows XP by finding its drivers.
Since the problem is with my office computer, I cannot answer the exact brand names of the ethernet card and wireless card. Shall I reinstall OpenSUSE 11.3 from the DVD I have?
Second problem: OpenSUSE does not recognise my external harddisk, it gives an error about mounting the device.
After having updated unconditionally all packages in Kde-desktop-factory-repository to get the latest version 4.4.4, I can no longer connect to the Internet through Knetworkmanager. I receive the the following message from a pop-up window when clicking on the Knetworkmanager icon
Code: KNetworkManager cannot start because the installation is misconfigured.System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution.KNetworkManager will not start automatically in future.I tried opening Knetworkmanager in a terminal as root user through 'su' but received the following message:
Code:# knetworkmanager knetworkmanager(2331): KUniqueApplication: Cannot find the D-Bus session server:"Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
