Ubuntu Networking :: Unable To Browse On One Connection
Jun 21, 2010
We have two internet connections here, one through Allegro which goes through an ISA 2004 box and an ADSL2+ connection.Everything works fine when connected via the ISA box. Windows machines (and last I checked, a Macbook) work fine on the ADSL2 setup, but nothing Ubuntuesque will work properly through it.DHCP is fine (and the same thing happens with a static IP), it gives a proper address, DNS works fine, it's just whenever a page attempts to load, Firefox will sit at the "Waiting for <site>..." status until it gives up. apt does the same thing.What I've tested it on so far is:
- a homemade 9.10 box
- an IBM xSeries 346 running 10.04
- an Acer Veriton M460 running 10.04
- an Acer Travelmate 6293 running 10.04
None of them will work with it. The Travelmate and the IBM are dual-boot, both will work fine on the connection under Windows. The Veriton is Windows only (tested using a Live CD) and is much the same.The router is a Thompson TG782T (Telsta branded). I'm at a loss with this. Any ideas? I can provide more info if needed.

The problem that I have been struggling with is while connecting to VPN server, I can't connect to other sites.
I am on 11.04, but this have been happening on 10.10 as well.
On Win7, I was able to browse the VPN and the other sites at the same time without any issue.
I also tried by checking ON the "Use this connection only for resources on its network" option (under IPv4 settings tab) but doing that is allowing me to browse all sites except the VPN site. The method that I am using is "Automatic (VPN)".
Need your help to solve this issue.

Running Ubuntu 9.10.
I'm connecting to a network via a Belkin F7D1101. The adapter appears to be working fine, as I can see various wireless networks available and I am able to connect to my personal wireless network. The problem is that even though I am connected and have a valid IP, I am unable to browse the Internet. I can't even ping the router!
I initially thought it may be an issue with WPA, but I have installed wpa-supplicant and as a means of testing, I turned off WPA on the router, and the issue still stands.

From today, I am unable browse internet using Fedora 10. Before this, I was using net in F10 with no problem, F10 was automatically configuring for net settings. But now I cannot connect to internet in F10, but I can connect to internet using windows xp. I have ADSL modem which automatically connects to internet when it is switched on. When I press any site name in Firefox it won't display any thing (in status it shows done).
And even following command not works.
Code:
ping www.google.com
But following command works fine ( I know yum search for software in repo using internet). I wonder how this commend works, while I cannot browse web.
Code:
yum search player
(I am completely dependent on linux). One more thing before occurrence of this problem I had installed xmms, xmms-mp2 and xmms-skins. I don't think this created problem.

I have a fresh install of Fedora 13 on my Toshiba Notebook. I am able to connect to the internet but can not browse neither by Ethernet or wireless. I have an Intel Pro/Wireless 2200BG wireless card and a Marvell Technology Group LTD 88E8036 PCI-E fast Ethernet card installed. The command ifconfig shows an ip address. I am able to ping by URL and IP address. It does the same with the firewall disabled. I have also disabled the iptable & ip6tables in the services. I have even set fire fox not to use proxy settings. I am just not able to browse at all.

Yesterday, I had the problem where I would browse to linuxpc2 and it would send me to linuxpc5. Theses computers are on my AD domain (server2003), so I decided to set a dhcp reservation on the server and del /var/lib/dhcpcd/*.* This fixed 1 of the 3 linuxpcs that had mixed up or matching ip addresses. What is happening now, and I've never seen this happen before, maybe it's a server thing, I'm not a huge network guy, so here it goes... from the server I can brows with the explorer to linuxpc2 and all is well, it's IP is 192.168.0.150, but when I ping it, or do anything command line (ping linuxpc2) it pings the address 192.168.0.101 (it's old address). From a linux box browsing to smb://linuxpc2 shows me no shares, and ping goes to ...101 address. If I brows to smb://192.168.0.150, all is well and ping 192.168.0.150 is fine also. What could be causing this? only 2 of my 8 linuxpcs are doing this. all installed and configured within the same day using suse 11.1 and updated.

I have been using Hardy for about 3yrs now and using dialup to connect to the internet. I have a 64bit ASUS with a nVidia ethernet interface........I have just recently switched to cable broadband with a wired connection direct to the eth0 port. I have another computer running puppy linux in which the broadband works. hence this is how I am typing this now. I have connected my ubuntu machine to the cable and the network admin shows a wired connection but will not let me browse on the net with any browser. Not really sure how I got puppy to find it, but it did.
I have used the network manager on both machines with one connecting and the other not. I know there a newer ubuntu's out but I really do like Hardy and want to keep it, but without internet connection other than dialup it seems a bit lame. I am not above using command line options as I use wodim and wget all the time, so my question is.

clean install of Slackware 13.1 64-bit. From day 1 I have been unable to browse Samba servers and shares on my home network. NFS, FTP, SSH, etc all seem to be working fine. I've been updating it regularly in case this was a bug, but I'm not so sure any more.
Reboot in WinXP sp3, I can browse fine. My wife's Win7 laptop works fine. My old Slack 12.2 system worked fine. I have not made any changes to the network other than adding this computer to the mix.

Ubuntu 11.04, wireless adapter BCM4312.The connection works for a while, for a random length of time from a few minutes to a few hours, then stops working. The laptop says it's connected, and the router says it's connected, but the browser can't find any Web pages, it can't find the router, and there is no response to pings from the router or any other device on the local network or on the Internet. "Host unreachable." When I try to ping to the laptop from another one, it times out.If I shut down the computer and try again a few hours later, it works fine again for a while, then after a while it stops working again.
In case it's relevant, sometimes when I restart networking from the command line, it says "ignoring unknown interface eth1=eth1," even though ifconfig -a lists eth1 as up with an ip address. eth1 is the wireless adapter. Another laptop with Ubuntu 11.04 connects to the same router with no problems.Using a fixed IP address doesn't change anything.

I just installed FC15 from scratch, and everything seems to be working OK, except that I cannot view other computers on my local network. I didn't have any problems when I was running FC13.I am able to get on the internet, and view the website I configured on this machine, but anything "network" related I cannot see.But now when I open Network, I am presented with MYGROUP, WORKGROUP, and my domain name (which is my actual "workgroup" as I don't have a domain). I cannot get to any of them - get the same timeout error as above.

I am trying to keep a VPN connection open between two Ubuntu 8.04 LTS servers, one in Holland and one in China. Unfortunately, because the connection in China is not great, about 1 time a day the connection drops. I have therefore devised a script, to be started by crontab once every 5 minutes, that checks the connection and if necessary restores it.
Code:
#!/bin/bash
ping -c 2 -W 10 10.10.10.73 &> /dev/null;
PING = $?;

Recently I have encountered Problems with my Wireless that I have not had before and I cannot fix. So I am asking for help.
6 month old Dell Insperion 1730 Laptop
Dual boot Karmic/Win 7
WUBI install.
No problems till about a week ago.A week ago I upgraded to Lucid and could not get the DVD drive to mount no matter what. The OS saw it but would not mount it...... uninstall and re -install Karmic.As soon as the patches are installed from the update manager, I lose my wireless completely. Wired connection still works.
I have tried different things from here and other sites. Basically I need to know how to enable my wireless card. There is no switch and key combinations (ALT+ F2) don't do anything. Connectivity in Win 7 is fine.
The Applet says wireless is disabled and so does the output from $sudo lshw -C network.It sees the interface but the network is disabled. lsmod shows the driver. iw list scan says does not support scanning. Newtwork is down.I know there is something in the updates that is messing the Intel WiFi Link 5100 up. On a fresh install all works till updated.

I am running Ubuntu 10.4 AMD64 on a HP Pavilion dv4Z-1200 laptop which I had manually assigned a temporary static IP through the DHCP server to the wireless connection, say 92. The server assigns the IP based on MAC.I later reassigned my standard IP to it, 80, but whenever I connect to the network with the Ubuntu wireless connection set to Automatic, it is still picking up 92 (which is outside the range of the DHCP assigning authority, which is 100-120).
I can force 80 manually, but I would rather the DHCP server issue the correct address, rather than tell it which one I want (kind of the whole purpose behind assigning static IPs, no?)I don't know... there is something wrong with this OS installation, because my internet connection is painfully intermittent, to the point of unusability, where other computers on the network are working fine. If I boot the same machine with 9.10 64AMD, the wireless assigned IP is correct and the internet seems to be working fine.

recently installed Ubuntu 10.10. Everything seems to be working fine on the installation except I have never been able to connect to the internet (I'm on mac connected to the same linksys router at the moment). I've been working on this for several days and have exhausted all the possible causes. Here is my setup.
My setup:
-I have tried running both 10.10 and 10.04 (I have 10.04 installed at the moment)
-I have windows xp on a separate hard drive on the same computer and the internet works fine when I boot in windows
-I have tried both automatic DHCP (which my windows uses) and manually connecting to my network under the IPv4 settings
-my "Connection Information" info under networks manager has all the correct information listed as far as my driver, IP address, Bcast, mask, DNS serves are concerned (except I don't know what 'default route' is for so I can't verify that that is correct.)
-my ethernet connection is wired connection that is connected to a linksys router
-my ethernet driver is sis190
-I can ping my router successfully, but I cannot ping anything (i.e. websites) on the other side of my router

Just turned on my computer after being away for a month and I am unable to browse the web when connected using my ethernet card.Skype is able to work fine and I am able to ping my router yet both Iceweasel and Chrome are unable to connect to any websites. Apt-get did not work as well, and Chrome states that there is an error with the DNS lookup, which lead me to try:
# /etc/init.d/nscd restart
yet it didn't work. I am able to browse the web normally when connected using the wireless card.
