Ubuntu Networking :: Can't Access Internet Via Ad Hoc Network
Jun 13, 2011
I want to connect to a wireless open ad-hoc network to have internet access. It worked a while ago (1/2 year or something) but some update must have messed something up so it doesn't work any longer. Situation: There is a laptop that is running windows 7 and is connected to the internet via cabel. A open ad-hoc network is configuered with sharing of internet connection, status of the ad-hoc network is "waiting for users to connect". I want to connect with a second laptop that is running ubuntu 11.04. I can find the network and connect to it.
Problem: I cannot get any internet access while being connected to the ad-hoc network. So my questions are: how can i find out if what causes the Problem? I suspect a driver issue, but I'm not sure. required information from Howto post a wireless issue:
I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?
Background infoMy laptop (MySN MG6.c) is dual-booted with Windows 7 and Ubuntu 9.10, and connected to the internet through a router (Digitus DN-11004-O), which is set-up to use DHCP. The internet connection works fine under Windows, and my previous laptop, which also ran Ubuntu 9.10, had no problems connecting to the internet through that router.The network adapter is an Atheros AR8131 PCI-E (also detected as Attansic under Ubuntu)stem infoResults from running various diagnostics (I have removed the output that relate to the wireless connection, as I don't use it):
Code: $ uname -a Linux valyria 2.6.31-14-generic-pae #48-Ubuntu SMP Fri Oct 16 15:22:42 UTC 2009 i686
I'm trying to configure internet access using KDE network manager. Added new VPN pptp connection, set gateway and other options but manager tries to connect for about a minute and breaks then. Here is /var/log/daemon.log
Code: Jul 1 17:35:22 dvinokurov-desktop NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'... Jul 1 17:35:22 dvinokurov-desktop NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started
[Code]....
As I understand the main problem is in "(IP Config Get) timeout exceeded".
Configuration: Kubuntu 10.04 x86, VPN server with MSCHAPV2 auth, no compression, no encrypting.
I have had a heck of a time trying to get my laptop running ubuntu to connect to my home network. I have managed to get it to work at my university which would seemingly be more difficult than getting it to work at home, so I know for a fact it isn't a hardware or driver issue. If I try to connect via ethernet cable from my router, it detects that I connected the cable but says "disconnected" and never lets me connect. If I SKIP the router and go from my modem directly to my laptop via ethernet cable it works great.
Using the wireless network tool I can see all of the wireless connections in my area. When I go to connect to my network it prompts me for the WEP key and when I enter it and hit connect it just keeps cycling and eventually times out and finally again prompts me for my WEP key. I know this network works as it works just fine on my Windows 7 partition. Another interesting note - both my wireless and ethernet connections both worked flawlessly and stoopid easily on the live cd but don't after the full install.
If I manually enter in the information for my wireless through IPv4 settings and enter in the Address,Netmask and gateway I can connect to my network - but then I have no active internet connection. Same deal with my wired connection. Is this because choosing this manual method grays out the DHCP?
I am trying to connect to the college campus wifi network, but having difficulties in Linux.I am dual-booting Windows 7 and Ubuntu 10.10, and I use Google Chrome web browser on both. When I boot into Windows, my laptop connects to the network (as I can see from the taskbar icon) and I can (and currently am) connect in Chrome.However, in Ubuntu, it connects (or so the icon indicates) but Chrome doesn't load any pages.The campus network is unsecured, but once you open the browser, you are prompted with a log-in page (student ID and password) to actually connect.Here is my output for iwconfig:
Code:

Okay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
if i'm connected to my wireless network it only gives me internet acces for a few minutes. The connection with my network stays but i have to close it back of and reconnect before i get back online.
can't access internet. The up and down icon appears by the network connection (upper right hand corner). When I review connection properties, I see that the computer has a valid address, subnet, gatway, dns, etc... But it still can't connect to the internet. I can't ping external addresses either. But I can access internal addresses (local router).
I have installed Fedora 8 on an old PC to use as a home network and I am having trouble getting a Windows PC running XP to get through to the internet, but I am able to access the internet from the Linux box with no issues. I can ping the gateway on eth0 from the Linux box, but I can't ping it from the windows PC. I am able to ping the IP address for eth0 from the Windows PC. My internet gateway is a modem/router from Hughes net. I also have a Netgear router between the Linux box and the Windows PC, but there doesn't appear to be any issues because I can ping both NICs from the Windows PC. I have pasted my Linux NIC config below. code...
I installed and tested both Windows server 2003 and Red Hat 9.0 with vmware workstation7. After installing 2003 can access internet but Red Hat can't. I want to test squid proxy server, send mail server, webserver etc. So, I would like to know how to setup WMware's network configuration for Red hat can access internet.
Below link is the configuration of VMware network setup both Server 2003 and Red Hat.

I am using wireless connection to access internet.
I have a fedora 10 box with two network card on eth0 I have a pppoe connection to the internet, on second card eth1 I share my internet connection end I set up a samba server but I don't know if the settings are good. How to do this settings right to work fine, the ip are assigned by dhcp I don't use any static ip .When I try to browse the internet from the other computers some site's like {.com ; .org ; .info} are block, other site from {.ro} are working. Someone tell me something about turn off all my filters, but I don't know where to find this filter to turn it off. And when I use samba I can't have and internet access or vice versa. My network look like that:
I have a wired lan at home with 2 XP boxes connecting to a router to a DSL modem. I want to network my laptop, running only fedora os, for file sharing, printing and internet access. I will be using the laptop probably exclusively for creating/maintaining a Drupal-based (LAMP) e-commerce site to replace our old one for our small family business.
I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo) - error code connection failed - error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error - no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)
I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.
I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection
I connected my laptop running with Ubuntu 11 in the LAN but I couldn't access internet.But I could ping to the other computers connected in the LAN. I tried the same thing with windows 7 in the same laptop and I could access internet.
I've a laptop which is connected to ethernet. I want to access internet from my N900 through wifi( available on Laptop). So i created adhoc network on laptop and connected my smart phone to it. But i still cannot access Internet from my phone. Where am I going wrong?? or is there another way to acces internet from my phone via laptop?
PS: I followed the procedure given in this link to create an adhoc network.
Is there a network trouble shooting guide for OS 11.2 that I could follow? I've shot myself in the foot so I should try to fix it.
I changed the DNS server addresses and the number of IP addresses on my router. I then set my Linux system to use static IP addressing and edited the network settings for my network adapter accordingly. I can now no longer get to any web-site.
By contrast, I also updated 1 of my Windows computers in a similar way; it continues to work without problem.
I am trying to get internet connection on Open Suse 11.2 through my wireless connection. I can connect to my network but there is no internet connection. The internet connection does work with other Linux distros and with Windows 7 laptop and Windows XP machines. I tried turning off the firewall but still no connection. What is even stranger is I can ping Google but in Firefox I cannot go to Google.
I'm kinda new to this, and usually i get help from a computor technician at school. BUT sins its Saturday, i cant get any help, and i realy need it. Well my problem is that i cant get any internet access using eth0 at my computer. I dont know what i have done wrong, if i have done anything wrong, it just reinstalled. ANd i dont know how to config it.
OpenSUSE 11.3 x64 KDE I dont know what happened it is a new install thats been running for 2 weeks . Now for some reason I can not access the internet or the router. Samba is working with Dolphin I can browse shares on local network both Windblows and Linux and ping local IP's. But I can NOT ping my router (the default gateway IP) with this box or access it with firefox so no internet. A VirtualBox of XP Pro running on this box has no problems with its bridged adapter getting out and seeing the router. I disabled the firewall, added gateway IP to network settings, disabled ipv 6 from the get go, added service provider dns's to nameservers tried opendns servers also.
Brand new to the OpenSuse project. I'm have an old AMD Duron running 11.3 and I am having no luck in connecting to the www. I'm using a D-Link usb wireless adapter. I seem to have an IP address for the PC. here is the print from ifconfig:
I just did a large patch on my opensuse11.3 system (upgrade of all installed packages), and whilst my network interface works, I cannot get past my router onto the internet.
I can connect to other computers on my network (here at home), I have an IP address via dhcp from my router, but I cannot get internet access, either from thunderbird, firefox, or simply by [URL] Clearly the computer was connected to the internet just fine minutes before since I did the large patch! Also, my other computers CAN still connect to the internet.
how i can debug it? It is just too coincidental I have upgraded everything and now somethings amiss!
If it's relevant, my router is a netgear WGR614v9.
A few things I've tried...
Code: linuxthinkpad:/var/log # /sbin/route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth1 link-local * 255.255.0.0 U 0 0 0 eth1 loopback * 255.0.0.0 U 0 0 0 lo
recently ran into a problem with my internet access. Im using open suse 11.2 on a Dell Vostro 1520 laptop. I managed to get my wlan running and i can use firefox to access my router. In my router the laptop is also showing as connnected, dhcp reserved an ip for it.However if i try to browse the internet, no page is loading, actually no software that needs access to the web is working.
i've installed opensuse 11.3 x86_64 and everything works great. after install updates and restart i cannot access internet from wireless connection. Knetworkmanager says it is connected, i have a dhcp ip, gateway, and cannot access internet.... i tried to configure from yast and cannot access internet...
I need to implement at my sister this kind of connection: She is connected on Local area network that has about 50-80 pc's, but for internet access she must start an pppoe connection. For now when she wants to use lan she must put her local address (ps: they dont have dhcp), for pppoe she uses dhcp. Problem is that on that way she can't access lan and internet at the same time. She must disconnect from lan and then start pppoe connection and vice versa. I'm intrested if it is possible to have lan access at the same time as internet access. some kind of tunel through lan up to isp. I was googling little and so PPPoE tunneling. Is it that what I need here?
