View 5 RepliesI've been using my upstairs computer with no problems recently up until this evening, when I rebooted it did an automatic scan of my disks, so I left it to it's thing and when I came back ubuntu had successfully booted, and had seemingly successfully connected to my wireless network as usual.
I've been through the wireless troubleshooting guide, paying special attention to sections 4 and 6 but to no avail, while I'm apparently connected, and have been assigned an IP by my router I'm unable to access anything outside my computer, including the router itself. This happened before, however I solved it by reinstalling ubuntu, and I'd rather not do that again!

I am facing very strange problem with my Dell with WiFi card (04:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100) It seems I am connected to the WiFi but can not access internet I have to disable networking and re-enable it to access internet.

Working with a Dell Inspiron 6000 and installed Ubuntu 10.10 just to get familiar with some form of Linux. The wireless card is Dell's 1470 and the chip on the card is labelled BCM4311 so that's what I went for. At first it showed an unconnected wired NIC and for wireless it said "no firmware", but now it doesn't say anything about either one of them, it says "no network devices available". I followed the instructions here [URL] for both "STA - No Internet Access" and "b43 - No Internet Access" and when it says to go to the additional drivers menu to enable the new driver, there's nothing on the list. I then tried [URL] that guide and [URL] that one. Don't say things like "just run a qf13 on the PCL so the ergotron bus will be cleared, it's probably a thermawhatsit in conflict with the meatloaf kernel" as I won't have a clue how to execute said instruction. More useful would be "open a terminal and type 'ireallyenjoynewcarpetting' then check if the output says 'blargh 010101' ".
View 9 Replies View RelatedProblem with this bizarre Wifi problem. I have searched and searched and cannot find a solutions. Unfortunately this affects 3 computers in my household. And as the resident amateur Linux tech support/Linux advocate, I will be held responsible if I don't figure out how to fix this quick. After some extensive playing around, this is the situation. I have this problem on Ubuntu 9.10, Mint 9 (based on Ubuntu 10.04) and PC Linux OS 2010.:
- About a week ago the wireless network I use stopped working. There was a major power failure on our block during this period. No idea if there was a connection. Since then, I have been able to connect, but I am no longer able to access the internet. I can ping my own IP and my router, but no website (niether by IP not URL).
- When I booted my computer in Windows, it connected to the internet. My neighbours (whose network I am using) are also windows users, and are able to access the internet without problems.
- I have found exactly the same problem on my wife's laptop running Ubuntu 9.10 and on a Live CD of PC Linux OS 2010
- I am still able to log into all other wireless networks without problems.
I am perplexed. Is it possible for a wireless network to prevent internet access to linux computers? And inadvertently? I tried disabling IPv6 (which wasn't being used anyhow), but this didn't make a difference. I also tried manually entering an IP address and other network details into the network settings.

I have a Centos5.4 64bit laptop, having an eth0 and a wlan0. I connect this wired eth0 to a wall socket to access Internet via DHCP (eg the assigned address is like 192.168.192.xx). I do not have access to the ADSL router. How can I turn this laptop into a Wifi access point to allow, say my Ipad or any wireless-only client, to access the Internet thru this laptop ?
That is, communication between iPad to laptop is wifi(ad-hoc connection ??), laptop to the ADSL router is wired LAN. The laptop need to have some bridging build in ? If you can refer me some concepts, then I can follow up from there.
Or better yet, has anybody does this before ?
I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?
the only error message I can find comes from "dmesg|tail"all it shows is
"no IPv6 router"any body know what is going on here or where where to look for more clues the next time I get around public wifi Oh the windoze washers and apple polishers don't seem to have any problems at all
I have a server that was set up by a friend so I have a location to save all my documents for work in a RAID array.
It is on a static IP address, I can ping the hub and other computers on the network absolutely fine.
I can't connect to the internet, the router in question is a Netgear CG3101D. Logging into the router I can see that the server is a trusted device and in all the parameters are the same as other computer running Ubuntu Studio.
Does anyone have any tips of how I can find out how to find what is wrong?
It is Ubuntu 10.04.2 LTS (Lucid).
I'm setting up an old box as a dedicated file-sharing server on the LAN as well as an internet web server for my personal web site but I have no network connection. My computer is connected to a router which is connected to my DSL modem. The router has the Ubuntu box's MAC address as well as a Win7 box, which connects to the internet fine.
Here is what I've tried:
1. Check routing table
Code:
2. Try to add a default gateway to the internet on eth2, this happens:
Code:
3. I edited resolv.conf, which was empty, adding:
4. I edited /etc/network/interfaces as follows:
Code:
Then I type the following:
Code:
And it keeps doing this endlessly because it's not finding the DHCP server, presumably...? This didn't solve the problem and so I attempted another configuration:
Code:
Still, not internet connection and no ability to apt-get anything (says packages not found)
So, this didn't work either. What I've tried should work, especially the route command. Now why won't it work?
i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.
i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.
here is what my setup looks like:
Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35

I'm running an own PPTP Server, but I can't get it to access the internet. All my PCs at home run in the 192.168.0.0/24 net, the PPTP Server has local IP192.168.0.5 and remote IP 192.168.0.80-99. The router to the internet is at 192.168.0.1, and the IP of eth0 on the machine where the pptpd runs is 192.168.0.4. I want to be able to connect to the internet trough that VPN and access my local LAN servers (which works fine so far). I can ping internet and local IPs successfully, but can not access them with a browser, or connect to them in any other way. I have 'accepted' all in/output and forwards.
I am running a Squid proxy on the same machine, and if I do:
iptables -t nat -A PREROUTING -j REDIRECT -i ppp0 -s 192.168.0.0/24 -p tcp --dport 80 --to-port 3128
I can access the internet through Squid, but of course Jabber/ICQ etc. Won't work then because it just refers port 80. But I want the PPTP Clients to connect to the internet directly, if I don't use that rule it's not possible to load any pages. But pinging works all the time. DNS is also working fine, but I can't even access webpages via IP directly. How can I allow the PPTP IPs 192.168.0.80-99 to get direct access to the Internet with Iptables?
I've installed centos 5 on an old computer with success and it works great.I can access the web server hosted on the centos server from any computer on the wireless and wired local network. I can also use ssh (putty) and nx client from any computer on the local network (wired and wireless) to access the centos server.On the wireless router I've configured a port forwarding to the wireless network interface on the centos server. I can access the centos server from the outside (internet) through this port forwarding both through http and ssh or nx client.MY problem is that I can't access the centos server from the internet through the wired network interface. Any attempt to view a web page or login with ssh or the nx client will timeout.
View 9 Replies View RelatedFirst time poster, some time Linux user. I've been reading and trying to create a wifi access point on my debian server. that is {intenet-router} <-> {server + usb-wifi} <-> {network users}
I've opted for this configuration as the server will become a firewall, traffic monitoring (sick of my windows machine getting hacked). I've spent a lot of time and I don't seem to have any un-clicked links in google left. I've read quite a few howtos and threads on this site and others ... I'm definitely missing something. Running: Debian Lenny (no gui)
[Code]...
I've also installed hostapd, and attempted a few things in there. Long run I want to allow wifi users to access the net. But will probably need iptables etc but just want to pass this step. I've see a few howtos seem to use ath0. It's probably only a minor issues.
I have a local network of two computers running ubuntu connected via a Netgear FR114P. I also have one of the computers connected WiFi to the internet. Can I get on the internet from the alternate computer via the network? Some assistance is appreciated as I am a relative newcomer to this area.
View 2 Replies View Relatedi would like to setup one of my old pcs as a file server and internet gateway; we are living in a large building shared with 40 others. the ubuntu box would be the one connected to the internet via ethernet and sharing connexion via wifi. i haven't started yet - presently, i am doing the ground work and reading before to start i understand sharing the internet is relatively simple and can be done from the GUI
What we would like is slightly like BT Fon or BT Open Zone in the UK: you can hook on a free network but in order to access outside (internet: email, web, ftp, etc) you need to login login would help us monitor fair usage. I imagine something with username and password for each user would do: as we are a few in the same building not everyone is actually paying for the connection and we don't want to end up with rather large excess bills. So the ones who are paying access both files and internet; those who dont just have access to the files on the local server.
Do i need Ubuntu server to set this up? What hardware would be ideal - given we are all far from rich but willing to have a nice setup
It would be great if you could share some knowledge around the topic and eventually provide some tutorial; also any heads-up on the hardware side would be great! (signal booster, etc - there's 3 floors and 3 buildings)
I use openSUSE 11.1 since quite a bit and I frequently use YAST (not as root of course). However, since the problems I have to deal with while trying to install WiFi internet access I meet the following problem. I call YAST, get the small authentication screen, I give the right password, which seems to be recognized as such, but I never see YAST appearing. So I can't manage neither my hardware, nor my software.

There is a new feature in Windows 7 that make u able to create a virtual WiFi and share ur internet access with many others.
I know there is ad-hoc but sometimes it has problems, for example I couldn't connect to my friend's ad-hoc network (he is using Windows 7) but I _could_ connect to the virtual WiFi he created, it appeared just like any other wireless network unlike ad-hoc
so is there any way to create a virtual WiFi and not ad-hoc in Linux?
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.

View 2 Replies View RelatedI just installed Ubuntu 10.10 tonight on my Acer Aspire One D250 and have no internet at all. I know both the wireless and wired internet work, as I am dual booting WinXP as well.
View 3 Replies View RelatedLet 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.
The place I will be staying at (Japanese Guesthouse) only offers internet through cable. What I'd like to do is be able to connect my other devices through wifi (Cellphone for example) to the Ubuntu machine connected through this ethernet cable in order to access the internet.I've searched for a good hour but I'm getting extremely confused about the gateways, bridges or whatever else people suggest. Most of what I've been able to find actually only covers getting internet through wifi and then sharing it through lan (I'm trying to achieve the opposite).
So if anyone could point me in the right direction, or at least tell me what terms I should be using for my searches, it would greatly help.Some computer info might be useful. I'm using a Dell XPS M1210, the network adapter is an Intel Pro Wireless 3945ABG and I'm running Ubuntu Desktop Edition 10.10.
I just installed Fedora 13 64bit Gnome, but I can't connect to the internet for some odd reason.
If you look at the image below:
I have marked the network icon, but on my desktop I don't have that icon for some reason...
Since I'm new @ Linux(Picking it up again) I went to the services and checked 2 services:
The network manager service was running but the status said: This service is dead.
And the network service was also running but status was: The status of this service is unknown.
I also went to the Administration menu and checked Network, the first tab showed no devices, but when I went to the hardware tab it did show my card.
I also don't believe that this is hardware problem since the card worked just fine under Fedora 9 or 10(Don't remember).
So if anyone got some solutions for me it would be great...

I've been running ubuntu for about 6 months, so i'm still abit of a newbie at linux but heres what im having issues with:I'm having troubles connecting to the internet on ubuntu, i have no problems connecting on xubuntu on the same machine. I can connect to my network but i cant access the internet on firefox or snaptic or any of that, but the weird thing is i can successfully ping address' in the terminal. I can also connect to my router config page in firefox using 192.168.0.1.
My internet worked perfectly about a month ago on this ubuntu install, so i cant figure out what i did to make it stop working. I think it may have something to do with the/etc/resolv.conf file because it only exists as /etc/resolv.conf.tmp and when i run "sudo dhclient wlan0" (or eth0) it says:
