Ubuntu Networking :: Lost Internet While Downloading Android SDK?
Aug 31, 2010
I was downloading the Android SDK when, mid download, I lost my internet connection. Now I cannot connect to the internet via hardwire connection. I can still connect on Vista, and I can connect via wireless, but I cannot have a hardwired connection.
I'm trying to set up a wireless AP with Internet sharing. I currently have the AP setup with hostapd and a dhcp server. The clients can connect but there is not Internet sharing. Now my situation is somewhat uniqe in that my internet connection is my teathered android cell phone. The tether app is azilink and i use openvpn to create a virtual networking interface(tun0).
I have a Droid Eris teathered over USB. I would like to share the the internet connection over WiFi. Currently, I forward tcp:8080 to tcp:8080 with the android tools. (I'm using the proxoid application.) Then I set firefox to use localhost:8080 as a proxy.How can I share this connection over WiFi?
I thought this will be as simple as in Windows 7 (connectify+virtual router). But it's not. So far I've managed to install a driver for an usb wifi dongle and now Ubuntu sees it
Code: $ iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 unassociated Nickname:"<WIFI@REALTEK>"
[Code].....
Could it be that the wifi interface is down or something?
PS. when I left click on network manger, I see that under wireless networks it's written "disconnected".
I have just bought a HTC Desire Z mobile phone, running Android 2.2.
It has a feature to allow, via the USB cable, use of the Internet connection on a PC so that the phone can connect via that, rather than use the 3G or wi fi when those are not available or not wanting to use them. I want to download lots of applications without draining my 3G data allowance.
I have searched via Google, and some people have said that it just worked for them. They plugged in the phone to their Ubuntu PC and they could use the Internet on the phone.
But I cannot get it to work. I am new to Android, and still figuring out the phone. In the Settings/Wireless & Networks, there is an option for Internet Pass-through, which is trying to connect but never does. Then it comes up with a message saying: "Unable to connect to PC" and asks me to install HTC Sync software (which is Windows only).
Is there something I need to install in Ubuntu to get it to work?
I've been reading around, but not had much success at all in trying to share the internet connection from my laptop to my phone.all the articles i read refer to earlier versions of Ubuntu and the packages they mention have become obsolete, according to the apt-get tool.im not that new to Linux, but my networking probably isn't up to scratch.if anyone could help me, that would be great, im using Ubuntu 10.04 at the time of writing.
as the title says , when iam downloading anything from anywhere ,, even when iam updating , i cant use anything else on internet ,,, no chat , not even browsing ,
I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.
I added RAM to my Acer (dual boot Windows XP / Ubuntu 9.1). Windows continues to work. Ubunty will no longer recognize the internet connection. I don't know if adding the memory is what did it, but I am puzzled why I can use the ethernet card from Windows but no longer from Ubuntu.
I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!
As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.
I am a non-techie, have been gratefully using Ubuntu 8.10 for a few years for the basics: email, web, documents, photos. I have somehow lost my internet connection, but strangely my email still works...!?!? My router is showing all the correct green lights, but I cannot get to any url. I am posting this thread via work (windows) pc. I have searched on this forum and in anticipation have done as much homework as possible, see below.I have a Netgear wired router. I cannot find Network manager on the menus and tried this from the terminal:
Code:
network-manager bash: network-manager: command not found networkmanager
I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!
I used this command to restart the networking but in vain Code: sudo /etc/init.d/networking restart
On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.
We have an Asterisk machine that we suspect periodically loses internet connectivity, causing all calls to drop. First, would this sort of thing be logged anywhere out of the box? I haven't noticed anything in /var/log, but that doesn't mean it's not there. If this is not typically logged, how I might go about logging it? I'm currently running a bash script from cron every 5 or 10 minutes which pings Google and writes success or failure messages to a log file. This works fine for extended outages, but if the internet connection drops and comes back between cron runs, it won't be caught.
After running a large update and rebooting a few weeks ago, I found that my internet connection had stopped working. My internal network still worked fine though, so it I know it's not the card itself or its configuration. After a bit of trial and error I discovered that simply running dhclient brings the connection up again, so it appears that something is interfering with the initial dhcp update to my ISP (or something like that; I'm no expert in this area. ) My usual policy in cases like this is to wait through two or three updates in the hopes that it's just a temporary problem, but it's been a while now and subsequent updates haven't fixed it.
I've tried looking around, but I can't come up with search criteria specific enough to narrow it down to my specific situation. I'm not even sure where to begin looking to diagnose the problem, nor do I know which package update(s) could've affected it. I'm not sure what might be useful, but here's the relevant entry in /etc/network/interfaces. I have it configured with a static internal address, with my router as the gateway.
On one of my F10 boxes yesterday, I installed several NM packages with yum update after being advised of their availability. Today, (the first reboot since installation) I no longer have network access on that box.
I installed Fedora today, and I automatically had internet connection, I never had do configure anything myself. Then, I was playing around with VPN for a good while (trying to set up the VPN connection to my University), and now, I suddenly lost my connection to the internet!
But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!
Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...
I already restarted the Computer, but that didn't work, and Google didn't really held either.
I thought to uninstall Gnome Network manager since it was always asking for to connect with wireless internet but it was working fine with wired internet.I uninstalled it and installed wicd. and then for some unknown reasons the internet disappeared.Kindly let me know How can i get back network manager without having internet and make internet work on my computer.I did searched a lot on Ubuntu forums using somone's else computer but no success.So if you let me know how to approach the problem in right manner it shal be great .
I have been using ubuntu netbook 10.10 on my Dell Mini 9 for the past few month without any problem; it connects wirelessly to the internet via a wireless router. Yesterday in the middle of web surfing, suddently firefox cannot see any website outside of my home network (Firefox displays Server not found page). No help when I rebooted a few times and connect to my home network via wireless or even wire cable; it can access files in my network file server (DNS-321) but not the internet. My desktop computer running Windows Vista and ASUS media player has no problem accessing the internet.
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
I have installed the wireless driver shown in the additional drivers tool but am unable to understand how to set up a wifi hotspot so that i can use internet on my android phonethe guides google returned are a bit too complicated with ip tables and all
I installed everything and am running android OS on Ubuntu (using androidphonedriver guide). The problem I'm having now is that I don't know how to install android market application to be able to install other apps like opera etc.).
Note: Not upgraded yet, still using Ubuntu Lucid Lynx.Recently I've had a strange problem with my internet connection. When downloading something I am unable to use the internet with other net clients. An example, this morning I was downloading a very large set of backup files from an online server where I store backups. The files totalled 1.5 GB and I was downloading them using a SFTP client called FileZilla - during the download I was UNABLE to access the internet using Firefox, pages did not load at all - NOT slowly, but NOT at all, the "can't find the server" message was displayed by Firefox.LikewiseThunderbird was not able to check/download email. Confirmation that no internet access (other than FileZilla) was possible was shown by trying to 'ping google.com', the response "ping: unknown host google.com". During all this FileZilla was downloading very happily and quickly and as soon as the downloads finished everything worked as normal.
The problem is not limited to FileZilla, when downloading a file with Firefox the same problem occurred. It is as if when downloading something all other net connections are put on hold including DNS lookups. In the past my internet connection might slow down as a result of downloading but I'd still be able to access the web and email just slower as a result of the download. This problem has only started happening in the last week or thereabouts.
I've just discovered the app TuneIn on my Android phone, it allows you to access radio stations that broadcast over the net, as well net-only ones, in an easy searchable interface (the 'backend' is the website radiotime.com).
Is there a way to do a similar thing on Opensuse? Currently I have a small list of stations in banshee which I had to manually add - a very painstaking manual process. Is there a plugin for banshee or another program that does this well?
I've been tinkering around with Linux over the past couple weeks. I've played arodn with both Ubuntu 10.10 and Linux Mint 10 and it's been a 99% positive experience. I have noticed an issue regarding my internet connection.
I've noticed when I download a file in Ubuntu (either from the software manager, BitTorrent or just a regular download in Firefox), browsing the web on my computer becomes near impossible. The download itself runs at a good speed for our DSL connection (around 200 KB/sec) but anything else near a standstill. Just loading ESPN.com on my PC can take a minute or two. Someone else playing a game in the house will go from a regular 100-200 ms ping to 5000+ right when the download starts. When I stop the download, internet browsing and gaming speeds go right back to normal.
The weird thing is the same thing happened when I installed Linux Mint 10. When I boot into my Vista partition, this isn't an issue. Downloading a file in Vista doesn't affect anything, but it's happening every time in both Ubuntu and Linux Mint.
