Ubuntu Networking :: Unable To Connect To The Internet But Can Connect To The Router

Apr 6, 2011

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.

Fedora Networking :: Unable To Connect To Wireless Networks And Unable To Configure Network

Jul 27, 2010

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.

Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network

However, there is no Network option under System>Administration.

Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

Ubuntu Networking :: Unable To Connect To A Small Number Of Random Websites: Otherwise Networking Is Fine

Dec 29, 2010

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net

As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)

ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Ubuntu Networking :: Unable To Connect To A Certain W-LAN

Jul 14, 2010

I have Karmic Koala and together with my neighbours we have a W-LAN which I was always using without problems. Now, a couple of weeks ago, my neighbour has changed the password to this W-LAN and since then ubuntu is unable to connect. The network is being recognized, but after the request to unlock a key for the network manager (besides, how can I unlock it once for all?) there comes the window with the request for the network-password, after typing it (correctly), nothing happens. The request for the password comes two more times and then ubuntu states that it is unable to connect.

- We have changed the password again - didn't help
- On Windows I and my neighbours get the connection
- My Ubuntu is able to connect to all other W-LANs

Ubuntu Networking :: Unable To Connect To A VPN

Nov 16, 2010

I have an Ubuntu server dedicated to running an openVPN server on my VMware ESX 4 host. On my Windows clients I am able to connect to the VPN; however, on my Ubuntu 10.10 workstation I am unable to connect. Here is what I have done. I have network-manager-openvpn and dependices installed as well as the openvpn package. When I hit the add button in the network manager for VPNs, I fill out all the needed information, but am unable to hi the apply button. I have also tried using the openVPN method for connecting. I download the client.ovpn file from the VPN server, and issue the following command:

Code:

openvpn --config client.ovpn

It asks me for the authentication user and its password and produces this:

Code:

Mon Nov 15 21:37:20 2010 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables

Ubuntu Networking :: Unable To Connect To WPA Home

Apr 20, 2010

First off, I should state that I am still using Hardy. I realize that it is many versions from the current release, but my schedule is full and provides little time to ring out a new distro and considering the nature of my problem I don't see much need.

The problem is that I cannot connect to my WPA home network. The wireless card is working because I can connect to any WEP network and before upgrading to Hardy I could connect, although not at first.

Have recently installed WICD which has not helped. WICD tries to connect but reports that it cannot obtain and IP address. Network Manager did not report anything but did seem to translate the password into an encrypted key (saw posts relating to this before but no obvious fix) Since switching to WICD I have not had the opportunity to test connection to a WEP network.

I do not wish to change the security of my home network to accommodate the operating system.

Ubuntu Networking :: Unable To Connect To Internet

Jun 10, 2010

Currently I have an Acer Aspire One netbook with Windows XP on it. I want to switch to Ubuntu, so I have the OS on a flash drive and I can run it fine. The only problem is,I cant see any wireless networks in range. I know the router is working because I can connect with Windows fine. A notification also pops up telling me i have to install missing drivers. But when i click on install, the progress gets to 99% and fails. It says i need the Broadcom B43 driver, but i don't know how to get it.

Ubuntu Networking :: Unable To Connect To The Internet

Aug 3, 2010

I've been trying for 3 days now, gone to a couple of ubuntu sites, asked some friends who unfortunately don't have the time to assist me, and gone through several forum responses on here to try to find the solution to my problem.The problem is my inability to connect to my wireless network. I have a linksys USB device for my wireless, and the wireless router is literally right next door to my room. I am able to find my router and my neighbor's router from my computer. However I can not connect to my router. It is WPA enabled, and I have the correct password. It is just unable to connect to the network, it tries for a few minutes then doesn't connect at all and says wireless network disconnected. I am currently hooked up to an unsecured wireless network, but I can't connect to the internet. I am using firefox, but it doesn't seem to connect to any site I try.

Here is the lspci

Code:

captain@The-Ship-Of-Capn-Alex:~$ lspci
00:00.0 Host bridge: VIA Technologies, Inc. VT8375 [KM266/KL266] Host Bridge
00:01.0 PCI bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP]

and when I ping I type in [URL] in the terminal and all that comes up is

Code:

ping: unknown host [URL]

Ubuntu Networking :: Unable To Connect To Wireless / Why Is So?

Aug 14, 2010

I just dual-booted my Acer Aspire 3810TZ laptop with Ubuntu 10.04. When I first tried to connect to my home wireless network, it connected fine. However, now whenever I start the laptop, it will not connect. The network appears in the available networks list, but it fails to connect. I know the network is ok, because I can still connect to it fine from Windows.

My network adapter is Intel Wifi 1000 BGN. Apparently (from [URL]) the drivers for this card should be part of the distribution.

I can't understand why it connected once, but (without any changes to the system at all) it won't work now.

Ubuntu Networking :: Ar5001 Unable To Connect?

May 12, 2011

The problem is wireless connections show up in the connections list but when I try to connect it will just keep trying to connect and will never actually complete. During the connecting process it will constantly ask for my WPA2 key. Wired connection does work but that is only a temporary fix to this problem. The phy0 wlan hard block is stuck to yes also, so that could be the problem.other info:Running Ubuntu 11.04 dual boot with windows vista 32 bitWireless card is Atheros ar5001 on Toshiba satellite laptop

Ubuntu Networking :: Unable To Connect With 3G After Not Using It For 2 Months

Jun 5, 2011

Yesterday I tried to connect using my 3G, it has been working since I installed the computer more than a year ago.

When I try to connect I get the following in the syslog (and daemon.log)

Code:
Jun 5 10:50:21 ubuntu NetworkManager: <info> Activation (ttyUSB0) starting connection '3 Bredband'
Jun 5 10:50:21 ubuntu NetworkManager: <info> (ttyUSB0): device state change: 3 -> 4 (reason 0)
Jun 5 10:50:21 ubuntu NetworkManager: <info> Activation (ttyUSB0) Stage 1 of 5 (Device Prepare) scheduled...

[Code]....

After alot of swearing ang scratching of the head I've resorted to trying this from i live cd, but with the same results. I know I've been able to connect using livecd before so I'm a bit worried that something might have happened with the hardware.

What I'm hoping for though is some way to determine that it is the sim-card and/or something on the operator side that is bork.

how to further pinpoint the issue? And/or troubleshoot the hardware? I should be able to send AT-commands directly to the modem, does anyone know how and/or the syntax for establishing the data connection?

EDIT: I'm using an Asus eee 901 with builtin 3G modem.

Ubuntu Networking :: Unable To Connect Via Ethernet?

Jun 22, 2011

I had this sticky problem with b43 drivers. Unfortunately, on my Acer Extensa 5620z I'm not even able to connect via ethernet, so I can't download upgrades, driver or whatever. This was initially with 11.04, so I've decided to get back to 10.04, but the problem persists. Then, here we go with details:

networking checked - is enabled.
Ip configuration (I've got static local address) - is ok.
Ifconfig - recognizes eth0.
Iwconfig - recognizes wlan0.
Ping - 100% packet loss, always.
dig - goes on timeout.
netstat -an - doesn't show any connection with external address.
