Ubuntu Networking :: Wireless Network Connection Active But Still Not Internet Connection?
Jan 24, 2010
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?
I have the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
I have a question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.
During the installation of Opensuse 11.2, I tried the wireless internet connection, and it kept coming back failed.I continued to install the system and when I got on, I entered the SSID (think that's the right way to say it), and the password.When showing that 'map' or whatever, it showed the SSID in the networkmanager.It also said "active".But when clicking on Mozilla Firefox, nothing happened. It just said the server is down.I'm on another Linux system now; so I know the wireless works. It worked great on a third one as well.It is some Atheros Communications, AR5001.I'm not sure what other information you need. Just let me know and I will do what I can to provide. I don't have opensuse up at the moment. I screwed up the dual boot. so right now it's been erased. I'll ask for help on that in another topic.
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
I've installed opensuse 11.2 on an old IBM thinkpad. The install went without a hitch and when I got to the desktop I inserted my Dlink DWL-G132 wireless USB adapter. Opensuse immediately recognised that a wireless device was attached and I could see my wireless network listed. I entered my WPA password and was able to connect to my routers configuration page by entering 192.168.0.1 in the URL bar of firefox. For some reason I am unable to navigate to any webpage. When I enter a URL firefox acts as though there is no internet connection. The only way I can get the internet on my laptop is to connect it to my router with a cable. I used a wired connection and ran the update utility thinking that perhaps an update would fix the issue but it did not. I know the adapter works because the laptop used to have windows xp installed and I could connect fine with that.
Does anyone here have any idea why I would be able to connect wirelessly to the routers configuration page but not to the internet? I appreciate any advice anyone may have.
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 have just done a new install of the latest opensuse 32bit and for some reason I cannot connect to the internet, when I click on mange connections the vpn tag is highlighted and all the other tabs are grayed out and I cannot select them. So I can't setup a internet connection wired or wireless. I was just using Kubuntu and did not have this problem. My card is broadcom.
I have a wireless cable modem/router and a PCI-E 1x wireless card in my desktop PC. It works perfectly until I connect my Ethernet cable to my local router and printer, no more internet connection. I am guessing there is a setting somewhere that tells the networking software that the hard wire connection is the primary internet gateway. How do I tell it to use the wireless as the primary gateway?
I'm using 10.04 I tried to connect to a free WiFi connection. I had the password for it too. I had been able to access the connection 2 weeks ago with no real trouble. Now, the thing at the top of my screen indicates I'm connected BUT I can't get Firefox to access any sites. I can't download email using Thunderbird. Pretty strange isn't it?
Finally I thought I solved my problem with the help of Dmizer. My networkcard wasn't functioning correctly due to the hardware switch on my laptop. For more information about this check this thread: [URL]
Now I have a new problem, probably caused by the problem above. I have a connection (so the network manager says) but no internet. I checked the network settings by using the ifconfig command in a terminal. This tells me that I have an address of 10.43.42.2 (or similar) which should be something like this 192.168.x.x.
I had already tried to use a command like "ifconfig release" but this didn't work. I know too much windows like but i had to try something. I also had the connection properties checked and changed to my network settings. After i did this I had still the same address (10.43.42.2 or similar).
Unless someone knows what is going on I'd like to know how to refresh of renew my IP address from the DHCP server.
Some information about my hardware and drivers:
NIC vendor: Atheros Communications Inc. NIC chipset: AR2413 (i guess, i do not have my laptop with me at the time of writing) Old driver: ath5k New driver: ath_pci (installed from madwifi)
I have no wireless internet on my 11.04. I can access my wired connection but my wireless doesn't show connections and isnt able to connect to any wireless network in the neighbourhood. (I had this probz too in 9.10 and 10.04) But none of the solutions work now. I already tried to blacklist the blacklist at76c50x_usb

There is this active connection in firestarter: ec2-174-129-193-12.compute-1.amazonaws.com (Port 443 - Service HTTPS - program python)After doing ps aux | grep PID it shows: /usr/bin/python /usr/lib/ubuntuone-client/ubuntuone-syncdaemon...This comes up in the firewall in each login, how do I get rid of it and how did it get there in the first place? Another question is if there is a way to limit a program's access to the internet. For example KCalender.. The things I type up in there may be stored somewhere. How can I disable complete access to the internet for that program and any other program so they can't backup, share, check etc. ?
I cannot Browse Even Internet is Active. Connected using Mobile Broadband using Samsung Mobile USB MODEM. (Modem is recognized Successfully and Connection Shown as active!) I cant browse or even use apt-get update in terminal.. no use. (Even I can see the Gprs icon in the Mobile Phone). WiFi is Perfect in this ubuntu (everything is fine) and Mobile modem working Successfully in Windows too. I have attached the picture.please see it.so you will understand everything

I installed Ubuntu 9.10 using the default setup (Gnome I think) and on my Gateway Notebook using a wireless connection. It appears to be working great and I can even see my Windows drives and network storage on my home office systems.I have also set it up to run my favorite Bible software on Windows running under VirtualBox. I then installed the KDE Desktop so that I can select either desktop when logging on.
However, once I am in the KDE desktop, I cannot connect to the internet. I have checked and double-checked and the wireless settings seem to be the same on both the Gnom and KDE Desktops but still no network or internet connection when using KDE. I might mention that I am using the 64 Bit version of Ubuntu.
I've been using this network forever With windows and I can't figure out how to connect to it now with ubuntu...I have a build-in wireless card and I know the name/password of the connection, but my computer cannot seem to locate it. I've looked through guides and none of them work..
I'm using a WUSB54GC network adapter to connect to my home wireless network. My network was not visible, so I added it and it shows connected, but when I launch the browser, I can't get a connection. I'm using Ubuntu 10.4. All other computers on the network connect fine and I disabled my firewall to see if that made a difference.
i just installed the 10.0.4 version. My problem is that I cant connect to the internet. When I add a new wireless connection, it says that its connected but i cant ping the router or connect to any websites. It keeps auto assigning me with a 10.42.43.1 ip which doesn't make any since because my router's is nowhere close to that.
I have an old Compaq Presario v2000 that recently had Ubuntu 10.04 installed on it. The wired internet worked when it was installed, but the wireless didn't. I tried to download the drivers for it and it failed everytime. I did an update thinking that the update might fix the wireless, but it didn't, it actually made my wired connection stop working. So now I have a newly installed OS on the laptop, and I can't do anything on it because there is no way to get any internet.
I just installed Ubuntu 10.04 . Need to get my wireless router working on my HP laptop. Have been using a Linksys WRT54G Router with windows and it is working properly. Tried setting up in NetworkManager but it does not work.
When looking at things in the Ubuntu terminal it says the network is DISABLED.
I had been happily using a wireless connection for about two weeks. The connection then went down for a few days. Since it came back up, I can connect to the network, but cannot access the internet. Other users of the network can both connect to the network, and access the internet, though people have experienced the same problem as me the last time the network went down (they could connect to the network but not access the internet). I have tried deleting and re-starting the connection, to no avail. I have looked around the forums, but haven't found anything that can help: do any of you have any suggestions? I am malarial and at the end of tether.It is not a problem with Ipv6, which is set to ignore, as it was in the past when the connection workedI am running Ubuntu 10.10 on an X61 Thinkpad. Below is the output of iwconfig, route -n, lspci, and what happens when I ping other network
Iwconfig: eth0 Link encap:Ethernet HWaddr 00:1d:72:9e:09:8f UP BROADCAST MULTICAST MTU:1500 Metric:1
We just set up a password for our wireless router (D-link DIR-615). WPA personal. After doing that, I can no longer connect to the internet. I can connect to the wireless router, however. Same problem for the Apple Macs in the house. We called Dlink. The fix for a Mac was to add DNS servers (22.214.171.124) under TCP/IP But there doesn't seem to be anywhere to specify a DNS server in Ubuntu.
I'm trying to setup network server for a week now and I was able to setup network in which i can ping the other workstation that is connected to my switch which is also connected to my server and I can also ping the server from local workstation.
I have 2 NIC, I use eth0 to dial to my dsl connection(ppp0 has the IP of my internet) and I use eth1 to connect to the switch and use to connect to the other local workstation
Now my problem is I don't know how can I share the internet connection from my eth0 or the ppp0 to my eth1 to the network, what do I need to be able to share the internet connection to the workstation that is connected to my switch.
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?
