Ubuntu Networking :: Cannot Access Internet Using Firefox When Wireless
May 3, 2011
I just loaded Ubuntu 11.04 onto Acer Aspire 5100 computer. I can access the internet through Firefox when I connect ethernet lan cable but it doesn't work when I use wireless connection. Although I do get the indicator in top right that says my wireless connection was established. Why I can't access internet with Firefox in wireless mode? I tried toggling the wireless switch in front of Acer but that didn't work.
After my "upgrade" to 10.04 I am unable to access the internet at home with wireless using Firefox, but am able to access the router. I am however able to access the internet at work, both use WPA password protection. I was also able to do the updates over wireless at home, despite not being able to access the internet. I am currently at work, and downloaded Google Chrome and did not import settings from Firefox, to see if there were any settings issues with Firefox itself.
I am coming from Windows XP Pro, on the same machine (and where I am writing this post from) so the internet clearly works on XP. On F13, the eth0 connection is activated and the drivers for the NIC chip were installed with the OS. The NIC is Intel Pro/100 VE. The problem that occurs is that the system updater (in GNOME) can access the internet, and installed a bunch of updates after installing the OS. I know it can get to the internet because the updates worked and in the System Monitor, I can see both uploading and downloading occurring during the updates. Now the problem is that when I open FF, I can't seem to get to pages, and I get the usual FF error (pic -- [URL]). However, I CAN get to [URL] as well as [URL] , but I cannot access several other subdomains on fedoraproject.org . I also cannot get to any other page online, ([URL] for example).
I have a machine (lets called it machine 1) with two networks card, eth0 and eth1. Both have static IPs. Once in a while the machine refuses to give access to the Internet via Firefox (eth0 is the route to router). Other machines on the network have no problems accessing the Internet. Eventually the machine would just magically start working again, but this time it just seems to have stayed broken. I've done some simple diagnostics and found:
a) I have another machine running Apache with a Wiki on our network - [URL]. Machine 1 is unable to connect to this Wiki. I get 'the connection has timed out'. I can ping 192.168.1.73 and it responds in the usual fashion.
b) If I try to ping www.google.com it times out with: ping: unknown host www.google.com. I can ping google using its IP address.
c) On machine 1 I have tried traceroute on both www.google.com and its IP and I just get:
1 * * * 2 * * *
And so on until hop 30. Doing this on any other machine on the network works. So while it seems I can ping internally in our network and outside, but when it attempts anything traceroute or URL related it does not work.
Running Ubuntu 9.10 Ive just got my wireless connection working after first having got the wired eth0 connection working.
With the wired connection I could SSH into my server through my firewall/router (via a forward). I can run up VNC, from there firefox, browse the web - all is well.
I have now setup the wireless connection, using a static IP, and I can likewise SSH into my server. I can run up VNC. I can ping my router. I can log onto it via VNC. I can browse to my router. But I cant browse the internet.
But I cant ping google.com. The reason is there is no host lookup service. Nslookup eventually says no servers could be reached.
So specifically, if I ping www.google.com Im told "unknown host". If I do an NSlookup on it I get timeout, no servers could be reached. However if I ping 126.96.36.199 I get responses.
I see no relevant entries in my firewall log.
Unfortunately I cant traceroute because the package isnt found - and of course I cant install it because I have no internet !
Strangely (to me at least !) if I then tunnel through SSH and browse the web, I have no problems. It works ? I know I am browsing through my SSH tunnel because whatsmyip gives the IP of my router at home, not where Ive SSHd in from. I can surf just fine.
why I cant do host lookups any more (and this did work with my wired connection, but whether its related to my change to wireless, or static IPs or both I cant be sure - it certainly appeared to happen at the same time). And, more to the point, what I need to look for/do to rectify it ?
As a bonus Id be interested in why I can SSH and browse via tunnelling but not direct from my server (via VNC). Just for interests sake !

I have a dual-boot desktop with Windows 7 and Ubuntu.Problem: Linux does not recognize my D-Link DWA-131 Wireless N USB Adapter. So, I can't access my wireless router or the internet.D-Link has a Linux driver for the DWA-131 posted on their website URL...that includes a readme file with long, strange, convoluted instructions on how to install the driver.
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

I have installed ubuntu 10.04 and STA wireless driver. I am using a wimax modem, the wireless is connected (have IP addresses) but I do not have access to the internet.I also have installed a windows XP as a guest OS (ubuntu is the host) on vmware. By using a bridged network connection, I am able to access internet. So I guess the problem is related to the ubuntu wireless driver.
With Encrypted Wireless Connection Not Able to Access Internet - no pings, internet browsing, etc. However, without encryption I am able to browse the internet. I need encryption ..
I am pasting diagnostics collected by shell procedure collectNWdata.sh..

I spent $70 on a brand-new Wireless-N adapter for my Ubuntu computer in hopes that I could get it to connect to the main router in the house and get me internet access. However, the driver install CD is designed for Windows and thus will not run. I have tried to get it to set up, but it takes no action when plugged in and I am still without access to the internet. what I can do to get my computer connected and save me from having wasted $70?
At work, we (like almost everyone) are still full-on windows. I am currently trying to get away from windows because I am not a fan. my current windows machine (different from my Ubuntu machine) is accessing the wireless network fine, and there are no obvious problems there. Also, my Ubuntu machine can access my wireless network at home, so I know there are no driver issues. I set up the connection for the Ubuntu machine, and it seems to be connecting OK. I can ping internal IPs and by all statuses, the connection to the router is functioning. However, when I attempt to load a web page or ping a domain or external IP, it fails. I tried to ping the IP, thinking if that worked, it's probably the DNS, but pinging both domains or IPs fails. I have looked around at forums and posts, but none of them seem to match my issue (that's probably not true, but I am struggling to see the commonality).

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:

I am building a CarPC which I'd like to have wireless internet access on. I have Verizon phone service so if there is a Verizon air card (not wireless card, an air card so I can have constant access without having to search for hot spots) that would work with Fedora 10 I would be very happy. I don't really know where to start and I can't find too much on Google, so I'm just looking for what options are available.
I started using Arch just a few days ago. forward traffic to the Wireless access point I created on arch. i am using cable internet (ppp0) which I want to share via a usb wifi adapter running as a WAP. I followed the instructions in this link to enable the AP mode. Afterwards I followed the instructions provided in the Arch Wiki to forward the traffic but because of my inexperience I am still unable to connect to the internet. Here is the output of iptables -nvL :

I am not really that good with linux, yet, I have a smc 2602W v3 wireless pci card, and I want to install it on linux, so I could access the internet, but I haven't found any solutions yet. Btw latest ubuntu desktop version. Info about the card: [URL]
I have I fileserver on my home network. It has a static IP and is plugged into the back of the wireless router. It is fine on the network but cannot access the internet. I noticed this when I was trying to update my package list. This is what is in /network/ interfaces:
Has anybody been successful in getting a N130 with a RTL8192E wireless chip to access the internet? I�ve tried practically every suggestion quoted on this message board �downloading drivers, from Samsung and Realtek which won�t open also linux versions with the same result, trying the Ubuntu compilation of Wine etc, etc. Am about to give up, which is a pity, because the Netbook version Ubuntu is very user friendly.
I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code: lancer@lancer-desktop:~$ ping www.google.com PING www.l.google.com (188.8.131.52) 56(84) bytes of data. 64 bytes from 184.108.40.206: icmp_req=1 ttl=55 time=179 ms 64 bytes from 220.127.116.11: icmp_req=2 ttl=55 time=176 ms 64 bytes from 18.104.22.168: icmp_req=3 ttl=55 time=158 ms
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)
I have an acer aspire one notebook (I gather firefox 2 is interwoven on the system?). Anyway, keep pressing firefox icon and it churns over put nothing happens. I found the following advice on another site: (Sorry this is so long, but I wanted to give you as much info for you to help me)
Press Alt+F2 to show the Run program window. Check Run in terminal, leave the input field blank, and click Run to open a terminal. If you're not familiar with the Linux command line just follow the instructions step by step. The easiest way is to simply paste the commands into the terminal with Ctrl+Shift+V. Most of them will only give feedback if an error occurs.
The first command uses wget to download Firefox 3.6 from an official mirror. You can edit the lang variable at the end, in this case en-US, if you'd like another language. All available languages are listed here, just hover over the download link to get the language code from the status bar.
wget -N [url]
The next step extracts the just downloaded file and modifies a link to point to it. In a few cases a connection refused error message may be triggered by sudo, which is not an error but a bug in sudo and can be safely ignored.
The next step links all plug-ins (not to be confused with extensions) to it.
Launch the profile manager using the command below. Create a new profile, name it anything you like and select it. If you want to keep your bookmarks export them via the bookmark manager first. You can then delete the old default profile.
firefox -profilemanager -no-remote
As a bonus you can also change the icon to the official Firefox icon.
Finally reboot the AA1 to make the desktop aware of the new icon and browser location.
However when I try the above I get the following responses at each point:
I do now have a new icon on the desktop! but still no internet.
I have just upgraded my system from fedora9 to fedora11.IN 9 i didnt hav any problem in accessing internet from firefox.but here in fedora11 firefox is not working .firefox cannot establish a connection to the server.i have tried to fix the problem by disabling firewall and proxy.but still im having the same problem..
I just tried installing Google Earth on my fresh 64 bit Fedora 11 install using autoten, which I used earlier to install java and some codecs. I also used leighs guide to install 64 bit flash and remove nspluginwrapper. All was working fine. Then I decided to use autoten to install googleearth. It failed early giving an error saying:
First error was: resolving dnmouse.org... failed: Name or service not known. wget: unable to resolve host address `dnmouse.org' Error getting repository data for googleearth, repository not found # checking installation.. Size of report file is 0 lines
Error window opened up saying: Google earth, was not installed correctly, please check you have an active connection. From this point on, Firefox cannot access the internet. I can ping google.com and dnmouse.com successfully. I did the update that included the new firefox 3.5, so accessing the internet and my connection is active. Konversation is working correctly. Just firefox is having the problem. Message: Firefox can't find the server at start.fedoraproject.org, or google, or redhat etc. I renamed the .mozilla folder, and restarted firefox, no luck. My /etc/resolve.conf contains the correct nameservers. Also tried a reboot, no luck, still have active eth0 connection but no FF internet access.
After about a week of successful running Xubuntu 10.10 off a live USB Firefox suddenly fails to work with the message "Firerfox can't find the server" Opening the error terminal in firefox yielded the message "Livemark Service: feed processor recieved an invalid channel for http://fxfeeds.mozilla.com/en-US/firefox/headlines.xml"
I'm having trouble setting up my desktop pc to access the internet via my wireless router. i have tried to set it up in networkmanager (it shows as connected when clicking on the NM icon) but when loading firefox or when trying to update opensuse i just cannot get a connection.
Am using Ubuntu 9.10 live disc.Plugged in the 3G wireless usb modem and followed network connection prompts- internet connection is working (little lighthouse icon and network manager indicates that it is connected).Firefox however does not want to connect to the internet.I've done the usual checks- deselected "work offline"; looked under advanced preferences and ensured 'no proxy' under the network connections tab. Problem seems to be firefox not recognising the live network connection, so any tips or workarounds are welcome.
I've been running Suse 11.2 KDE on a 64-bit Dell Studio 1535 since last week's release, and have had no trouble using Firefox. At some point today, however, it stopped accessing webpages -- or, when managing to grab a page, it would do so without full html rendering. 95% of the time I get an error splash, while the other 5% I get some sort of truncated page that looks nothing like it should. Konquer and Opera work fine, as does KMail.
I tried deleting the profile.int file (no luck), then uninstalled/re-installed (no luck), then uninstalled and deleted every Mozilla/Firefox file I could find in order for a fresh install -- but this has not worked after several attempts. I still cannot get Internet access. How to completely wipe-out Firefox in order to allow for a totally new installation?
I have a dual boot in windows 7 and ubuntu. WiFi came with windows 7 but doesn't work at all in ubuntu.There are no drivers in my hardware drivers. I use one of those laptops that came with a built in atheros wireless adapter.
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
