Ubuntu Networking :: Connects To Internet But Not To Home Network?
Aug 25, 2010
I installed Ubuntu 10.04 32-bit on an old desktop (1.5ghz Pentium 4, 20GB hard drive, 768MB RAM) a week or two ago, at the same time that I installed Xubuntu 10.04 on an even lower performance IBM tower server. The server functions perfectly and my other (Windows XP) desktop recognized it from the start, as did the Ubuntu desktop. However, I rearranged a few ethernet cables the other day without turning off the desktops and ever since my Ubuntu machine does not recognize my server, even though all of the devices are connected via ethernet cable to a linksys router and it connects to the internet without a problem. I'm a linux newbie - this is my first move away from Windows - and I don't know where to turn. Far more confusing is the fact that, when I boot from a LiveCD, the network is recognized and I can read/manipulate files on my server without a problem. Oh, and I briefly flirted with OpenSUSE KDE (not as noob-friendly as Ubuntu, so I'm back) and encountered the same problem.
Needless to say, booting from the hard drive is preferable to booting from CD every time
I recently installed Xubuntu 10.04 on my desktop computer that had a USB wireless adapter DLink DWA-140. I didn't have to install any additional drivers to get it to work. I put in the network SSID and the password and was connected immediately. However, when I try starting firefox it doesn't load any sites. Can anyone help me in approaching this problem. I have a DLink DIR-655 router. If I should gather more information to get this problem solved then please let me know and I will do so. Edit: Now I am unable to connect to the network. When I click the network icon in the taskbar, my home network is not visible while it is visible under another ubuntu computer I'm running.
I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet
I know Windows forward and backward but I am so new to linux it's just wrong. I just installed fedora (like 1hr ago) on and old toshiba laptop with a WiFi PC card. Everything seems to work fine except. My Networks connects to my home Wifi network but it will not connect to internet. When it connects the IP address isn't even close to being in the same range as my other laptops and PCs. Like I said I'm new to linux but I'm wanting to learn. Any fixes for this issue? Which linus book is the best one to read for a beginner? Other then not connecting to internet I have no complaints.
Got a laptop with a RTL8187B wlan card, installed opensuse 11.2 on a 50gb partition. Card was detected straight away but only connects when I enter ip addresses manually, DHCP don't work.
When it is connected it always stays at a speed of 1mb/s and it cannot ping my router or anything else.
Me kernel is 2.6.31.8-0.1-desktop
Searched around the forums but no love, tried compat-wireless but it started crying about dependencies. Modprobed it too..
In openSuse I can connect to a wireless network. It says that it is connected, and I can open the router page (http://192.168.1.1/basic.html). But I cannot load any other pages. Nothing else recognizes internet either; I tried using konqueror, YAST and wget with the command line, and none of them could load anything. It is not a router problem or a wireless card problem because both Ubuntu and Kubuntu can connect, from the same computer. I know this is odd because in the only other thread I could find with this issue, it was a different distro and installing openSuse seemed to fix it.
I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.
Let me start by saying that I am new to ubuntu, and that I always use forums as a last resort.
I installed ubuntu 10, and immediately after the Wifi card deected my network name, and actually connected to it, but then I opened up firefox and....no internet.
Since then I have been trying to fix this problem, and after some research I found out that my card (PCI Cwp-905) is RT2760 based, and I downloaded the linux RT2760 drivers for it.
The driver folder contained a readme file with commands you should enter to install it, and other setup files. The problem: every command I typed in didn't work. I tried "make", and then "sudo make", but just got permission denied each time. I am now at a dead end. (Please note that I changed my directory to the folder location before doing this)
Does anyone know what I am doing wrong? If you want I can attach the driver files.
I bought a laptop today (Compaq Presario cq62) and loaded Ubuntu 10.04 on it. Everything has been running great, but the Wifi has been acting up. It connects to my router for a few seconds to a minute, and then stops all data transfer (although it still shows that I am connected to the internet). My other computers running Mac work fine. I took my laptop to another place with wifi, and it did the same thing.
The data transfer seems to stop when there is a lot going on. Whenever I try downloading new software, it gets to exactly 5% then stops. If I disconnect the wifi, and reconnect it works again for another minute. I may need to be walked through any terminal codes.
On that note, where would be a great place to read up on using Ubuntu (online book?)
trying to run 10.04 netbook live from a memory stick with a view to installing it on my laptop. However although I can see my wireless router and connect to it I cannot access the internet. I have tried this on my laptop and desktop with the same result. I was however able to download Seamonkey browser using the software manager....this also cannot access the internet. Both of my PC's have no problem when using XP or Linux Mint.
I have also discovered that if I piggyback, using Ubuntu 10.04, on a neighbours open wifi link I can gain access to the internet. My wifi is using WEP protection but as I said I can set the link up to the router, entering the appropriate key code, and have a good signal strength, I just cannot access a google search page.
The computer connects wirelessly to a router. The router is connected to the internet and that is working well. (If i use a cable connection to the router, I can reach the internet).
Why wont the wireless connection reach the Internet? It is a strong connection. It worked before wirelessly. I am on 10.04 beta, with the recent updates installed.
i have a leased line ( speed 2 MB ) which we use to connect to our mail server , oracle ERP etc.. we have a dhcp scope defined as 192.168.100.1-192.168.101.254. with a default gateway as 192.168.100.90 ( which is a cisco router ) we have a pix firewall ( 192.168.100.10 ).. now the gateway passed all the request to firewall..
we have an ADSL of 4 MB speed.. ip is 83.*.*.230 from ISP. i have a proxy server ( squid ) eth0 is connected to ISP (83.*.*.230).. eth1 to LAN ( 192.168.100.79 ) now the problem is when i put default gateway to eth1 ie 192.168.100.90 the squid connects to internet via leased line.. if i leave the default gateway field empty on eth1 , the squid connects to internet via ADSL ( which i want ) but the problem is no one on the lan cant ping the squid server ( no connectivity to internet for the whole LAN ) how can i solve this problem? i want squid to connect to internet with ADSL, but if i put gateway on eth1 ie LAN squid goes through leased line which i dont want to happen.
Since I have 3 Network cards in my Desktop PC I've configured it to act as a Router using GNU/Linux Ubuntu Lucid in combination with Samba so I could share my internet connection. It works on any laptop a connect to it using any of the network cards ports [regardless of the operating system installed on the Laptops], but when I plug that same network cable to any Desktop PC [regardless of the operating System installed] it doesn't even light the LED in the netcards. From the Client PC seems like nothing is plugged in the the netcards.
I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

I'm trying to connect to a Cisco VPN at work from Ubuntu 10.10. On earlier versions, I was able to import the config and get it working. In 10.10, though, the best I've gotten is being able to connect to the VPN, see the welcome message, and have packets sent over the tunnel. I don't receive any packets, though.
The command-line vpnc client connects just fine. I found this bug report: [URL]
The symptoms it describes are exactly what I'm seeing. The apparent solution is to "make sure in your config that LZO Compression is enabled (checked) under Advanced"; however I see neither an option for compression nor an "Advanced" tab, button, or anything on my VPN config in Network Manager.
I got a little problem with network manager. I got two connections in it, with two different DNS-Servers, because the one of my provider is very slow I surf with opendns, but sometimes that slows down too, so I want to change if necessary. Both connections got the same fixed IP.That worked all fine, until I got my new router (it's a Netgear WGU 624). It's connected by cable and I configured it like the old one. But for some reason instead of connecting to the manually configured connections, my fedora 10 creates a new one "auto eth 0" with a dynamic IP. So every time I boot or switch on from standby my PC connects with this one and I have to manually set it to the right connection. There's no chance to edit or delete it cause those two buttons are grey and won't work. I also tried restarting network manager manually and I also tried starting it with su as root.
I'm running the newest version of Ubuntu on a usb while I have a hard drive problem with win7. Internet problem is that I'm using a D-link N USB adapter to connect- it recognises my home network, even looks like it's connected, but nothing happening.
I'd like to set up my home network with an Ubuntu file/internet server. In addition, I would use this server to monitor internet traffic. What hardware/software would be required?
My current network is as follows:
Laptop 1 Ubuntu 9.1 Laptop 2 Vista Laptop 3 XP Desktop Ubuntu 9.04 (would be used as server)
All connected thru linksys wireless router to cable modem.
I have been trying to get a home server to do what i want but just not getting there.I only need it to serve up the files to a home ( non internet ) network.I saw that filezilla also comes in a Linux version also. I am going to give it a try next. Anyone use the linux version of filezilla ? What happened did it work not work ?
I'm sorry if i'm posting this on the wrong place and if this problem is solved in another post but I couldn't find anything to solve my problem. I'm kind of noob when it comes to these kinds of problems.
I have an Acer Aspire One 110L. I had Ubuntu 9.04 on it working fine but one day something happened. I connected to my wireless network and I got no Internet. I couldn't even ping to my router. I thought it was some kind of bad update I've installed that made it to my computer, so today I've installed Ubuntu 8.10, following this tutorial: [URL].. While following it, I used a wireless usb card to connect to my wireless network and download the packages needed. I've installed WLan via ath5k Method at the beginning, but right after unpluging the USB wireless card, the other wireless card from my Aspire One had the same problem as before. It can connect to the network but I can't even ping my router. No signal. I've tried the madwifi method too but the problem is still here, because it must be something else. The drivers must be fine.
Can anyone please tell me what to do here? I'm pissed off already with this problem. I don't really know what is the problem. I have another 2 computers at home and they work fine via Wireless.
I use vpntunnel.se and followed their tutorial for OpenVPN and it connects and assigns an IP. However, once the sequence is initiated and I open my browser I cannot connect to a webpage and get a "cannot resolve" error. I e-mailed their support and they suggested I change the DNS of my network settings. I did that but the same problem. Once I close OpenVPN my internet works again. It works in windows, so I know it is not my router...I use a wireless connection with my router. I don't know if this has something to do with anything...
I am using a fully up to date openSUSE 11.3 and today, I decided to upgrade my KDE 4.4.4 to Factory. The update went without a hitch, everything continued to work, including all of the items in my workspace.So now I am running KDE 4.4.95 and it looks nice. I like the new System Settings where the advanced tab is gone and everything is presented in a single window.
The only snag I have hit so far, is that Knetworkmanager no longer displays the network that I am connected to when I right click its icon in the tray. The screenshot may make clear what I am talking about.I am currently connected via a wireless network, which nm-tool confirms. However, it is not shown in the Knetworkmanager menu.
my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."
I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.
just wanted to ask what is the name of the process that connects to the internet in fedora 12, i tried networkManager and /sbin/dhclient but when i tried to stop them, the my connection didn't disconnected.
I installed Debian Squeeze on my system two days ago, using a wired connection to internet (which worked fine). After that, I had to install the non-free wireless package in order to scan wireless networks. It now works fine, and I can connect and get to internet. But with wired connection, i connect via eth0 and none of my applications work. And they're not in offline mode.Also, i already went here: URL,,, and I checked if that was my case. I tryed what they say several times in some different ways, but I still can't connect. Even more, if I change something like they say, I get "unmanaged device" and I can't even connect to the internet. And the wired connection works, I'm using it right now on my ubuntu 10.10.
If you want more information, I just tried to ping sites like google.com or ......com using network preferences and it does work, it gets 100% of the packages back around 50ms later, so the internet appears to work. Also, when I connect via wireless, everything works perfectly.
I have an acer aspire one running Linpus Lite (i think) - worked fine for a year on wireless and LAN but yesterday I started it up, it connected fine and clicked up the wireless icon but when clicking the "Browser" icon it won't open the browser screen - repeated clicking brings up a screen that says Firefox was stopped and is still open - please shut it down- How do I do this when there are no screen commands ? I have tried switching off and re-starting the unit but no effect. What can I do to fix it ?
My wireless adapter connects to my WPA2 network perfectly, but when I run firefox it says it can't load the webpage, no matter what page I go to. Also, downloading new software doesn't work either. Any ideas please?
Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.
Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.
I have set up a FTP server in my home (FileZilla) and everything works how it is supposed to. I understand that port forwarding is required and can easily set that up. My question is what IP address do I use to connect to it when I am outside of my home network. Do I use the one my ISP gave me? And how do I figure out what that is? Could my ISP be using NAT that could be messing things up for me? Could there any other configurations that I need to perform ? Also do ISP's frown upon home ftp servers? (USA)
