Networking :: Windows Can't Connect Internet After Install
Sep 21, 2010
im installing Windows 7 and CentOS 5.5 on my computer..but, since i installed centOS, my windows can no longer connect to the internet. i already diagnosed and it said that my ethernet/LAN cable didnt connect (the error message is "plug an ethernet cable into this computer") although i've already checked that it is properly connected and when i see the ethernet port behind my PC, the LED indicator is on.However, when I switch to CentOS, the internet is working fine.
I have a dual booted Windows XP and Ubuntu 9.10 box and have an unusual problem in that after connecting to the internet on Windows I cannot connect using Ubuntu. I don't believe it is actually a problem with configuring my Ubuntu connections because when I get up in the morning Ubuntu connects without any problem - this problem only exists (and persists for at least several hours) if I try to connect immediately after connecting on Windows. I don't know how long the problem lasts because I usually get so ***ed off I just go to bed and then in the morning I can connect. As I have recently been forced to change my ISP due to moving house, is it possibly a problem with my provider's service and not a Ubuntu problem at? I have a second Ubuntu 9.10 box which I have to manually connect [URL] which does connect even when the dual booted one won't.
My friend is trying to share his clearwire connection with me using Windows ICS. Using network-manager or wicd, I am unable to connect to his share. I am able to connect unencrypted with iwconfig, to the ad-hoc network, and then use dhclient to gain ip address.
I am not able to connect to WPA encrypted share using network-manager or wicd. nm-applet crashes when trying to connect. I am attempting to setup wpa_supplicant, but haven't got it working yet.As usual, the wireless networking out of the box experience in Ubuntu doesn't work. This is extremely frustrating. If Ubunut's goals are to be the default desktop, then these guys need to get wifi that "Just Works"...
I installed Ubuntu (10.04) today and it has gone smoothly except for the fact that I can't connect to the Internet when in Ubuntu (connection works fine in Windows XP). I am using a wireless USB card (Linksys WUSB600N) to connect.
The weird thing is that the card detects all the local networks, asks me for a password to my network, and it even says it is connected to my network after I put the password in -- but when I open Firefox no pages will load.
There is another weird quirk as well: Ubuntu will not restart or shut down properly (it hangs around indefinitely with the little white / orange dots going across the screen) unless I first remove the wireless card from the USB slot. But that doesn't bother me as badly as the lack of Internet.
I've replaced Ubuntu 10.10 with F13 and can't connect to the Internet.
I'm using a WiFi connection to my router. I receive an IP address via DHCP. I can connect to the router's web configuration interface, 192.168.2.1. Same with my NAS web configuration interface.
I've also tried with Live CD (F13 and F14beta). Same thing: receive IP, connect to router's web interface, can't connect to Google.
As a check, I tried Ubuntu Live CD and I can connect to the Internet.
I've also tried F13 Live CD on my laptop. Can't connect to the Internet.
I've just installed ubuntu 9.10 (64bit) on a new Dell Precision M4500 (actually I've made it dual boot with Win7).
I'm unable to connect to the internet. For now, I'd like to get the ethernet card working.
Connection is fine under Windows 7, so I think it is not a hardware problem.
To start with in ubuntu, I *was* able to connect to the internet via the NIC. Subsequently (not sure why), the ability to connect became intermittent: at startup, I would either be able to connect or not. If able, I remain able until reboot; if not, I remain unable until reboot. Now, I am not able to connect at all. All this makes me suspect that the NIC driver in ubuntu is OK.
On the suggestion of a local expert, I manually edited /etc/resolv.conf(originally blank) to contain the lines: search tamu.edu nameserver XXX.XXX.XXX.XXX (using the IP the expert gave).
less /etc/network/interfaces shows: auto lo iface lo inet loopback
I have a Dell XPS 420 with Ubuntu 10.10 (2.6.35-23-generic x86_64). My internet used to work (out of the box) without any problems, but after install of Windows Vista (Home Ed. 32bit), I am unable to use the internet in Ubuntu. The network card is a Linksys WMP600N Wireless-N PCI Adapter. In Windows it works without problems.
In ubuntu, the network manager indicates that I am connected to the network, and I have an IP address in the 192.168.* range. I am able to ping the router, but unable to ping outside addresses. I have not changed anything, but still my wireless connections has stopped working.
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.
I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
I have a dual boot laptop. It has both Ubuntu 10.10 and Windows 7 running on the same machine. Windows can connect to the wireless flawlessly, however, Ubuntu seems to be so fuzzy. The first time, it can connect to the wireless internet in the dormitory. The succeeding days, the network icon just keeps on turning as if it's trying to connect. What's wrong? Is it because of the drivers? If that's the case, then why are there times when I can connect to the wireless internet?
When i boot my computer and open ubuntu version 10.04.1 the internet wireless connection i have connected automatically. Now, for one reason i don't know, the internet did not connect to the internet. The progam display a message to uncheck the checkmark in the File Menu. After doing this, i refresh the system but it still not connect.
I'm running Ubuntu 10.04 inside VMware Player running under Windows Vista and I can't connect to the internet or the host computer from the Ubuntu.
I have set all the VMware services to manual (like VMware DHCP Service), but starting them manually doesn't help.
In VMware, the network seems to work (there is a green dot beside the network icon) and I have tried both Bridged and NAT settings.
ifconfig doesn't show the eth1 interface, unless I give it as a parameter (or use -a). I think this means that Ubuntu thinks that the network isn't connected at all.
I have a fresh install of CentOS 5.5. I am trying to browse to the Windows machines on my network (Places > Network Servers > Windows Network), but I get a blank window. I am able to ping the Windows machines using their IP address, but not by their name. What do I need to do to be able to see the Windows machines and also to connect to shared folders on these machines? So far I have tried starting SMB (via System > Administration > Server Settings > Services). I have also tried changing my smb workgroup to "WORKGROUP" (the default was mygroup which did not match my Windows machines.
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

After working tirelessly for that past 2 months to make my ethernet card works on my toshiba laptop, finally the computer recognizes the ethernet card. But the problem now is the network configuration as i can't connect to the internet. i'm able to assign the eth0 an ip address and netmask and make it up running, and when i do ifconfig -a i can see all is fine but yet i'm not connected to the internet. So i checked /etc/sysconfig/network-scripts and found out that ifcfg-eth0 and resolv.conf are not present. Now my question is how can i create them(step by step pls)? and what should be their values? And is that all i need to do to configure the network and have my internet connected?
I'm trying to connect to the ethernet using my ethernet cable but it seems that my Desktop is not able to get and ip address.
I connect the cable to my laptop, using slackware OS too, it can connect and surf the internet. Before i install my Desktop with slackware, i have tried connecting to the internet using windows which shows that the network card is working.
I have tried to use this command as root:
Code:
But the system still does not get the ip address of my network.
I wonder if slackware has install my network card in my system.
My 1st question: How do i check if my network card has been install and configure in the system?
This is the network card in my desktop when i use lspci command:
Code:
My 2nd Question: How can i set up the desktop to connect to my network?
My proxy server just stopped from connecting to the Internet. I am using webmin squid proxy. All my setting are fine, meaning that l did not change them. My ip address for the Internet is 192.168.0.1 and for my internal LAN 10.0.0.34 and subnet mask is 255.255.255.0. I have check all the settings seems fine and the squid is running on webmin what could be the problem or where should i start my troubleshoot it. Firewall is turn off. It was working this morning. I did not do any configuration.
I installed fresh copy of fedora 11. I can't activate or deactivate ethernet from system>Administration>Network. Why is this............I can connect to internet directly by enabling network icon on right topmost corner. Even doing so dosen't guarantee connection at times. What could be wrong here ? Also my network icon shows it is disconnected whenever I start my computer. Cant fedora 11 just connect to the internet while it boots ?
I just installed Fedora 14 on my laptop as a Dual Boot with Windows 7.The problem I am having is that I can't get fedora to connect to my wireless internet.I can access it just fine on the windows side.On my Fedora desktop at the top there a little icon with two little computer monitors there is also a little x by them. Here is whats in the computer as far as networking devices:
Realtek RTL8191SE Wireless Lan 802.11N PCI-E NIC
I also have a:
Realtek RTL8187 Wireless 802.11b/g 54Mbps USB 2.0 Network Adapter
No matter how I configure settings it don't work.If I have to download something on the windows side to fix this please let me know how to get it to the linux partition.
