Ubuntu Networking :: Internet "stops Working" After Being Connected For About A Minute?
Jan 21, 2011
my netbook (running 10.10) has recently decided to only work with my wireless for a short while after connecting. After this time, it just won't load a page at all, but remains connected to the router. Disconnecting then reconnecting to the network allows me to use the internet again, but only for a short while. This is a recent problem, and the netbook used to "just work" with wireless.
I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.
Often i have an active connection on the tree network with an internet dongle according networkmanager, but ping is not working and firefox and thunderbird also don't have a connection. Skype however is working at that time. (testcall to skype is working) My present solution is to disconnect and connect a couple of times again until i can ping a commonserver on the internet, and then everything is working normal. Many are stating networkmanager is buggy, is this a known bug and is it worked on or do i need to install another program. Has any of you an idea what could be going on and how to solve it, permanently. In the way it's automatically right when connecting.
My dongle is of type: Huawei E 1550 and often i have a normal connection.
This holds true in Transmission and NOT in Vuze. UPnP is enabled, ports are randomized and open each time. Pings to outside still work fine, but I cannot browse to websites (404 errors) when the app is running. I'm stumped, is Transmission locking all other in bound traffic/ports except the one it wants to use?
Not sure if I've listed the specs of this machine before, so I'll do it again. 'm running an HP Pavilion 760n with 512MB of RAM and (I think?) a Pentium III processor... not sure on that one right now. It's currently running a laptop version of Ubuntu 10.04.I went to log into my online classes tonight only to find that the computer wasn't responding at all. I did a hot shutdown and restarted it, and now the system isn't detecting the internet connection at all. It should be noted that the connection was working perfectly fine earlier today, perhaps 6 or 7 hours ago.I know it's something to do with my computer and not my router, as I'm on my wireless network from a Windows 7 laptop and it's connecting just fine.
In viewing another thread,..lems+-wireless, I found a bunch of commands that it was said would be helpful diagnosing this issue. That said, below is the output of all the commands that I could think of.
Sudo ifconfig -a eth0 Link encap:Ethernet HWaddr 00:e0:18:5c:45:7a inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0
I have to connect to my university's network. I was using ethernet through our router, but now I cannot do that. I recently installed the TRENDnet TEW-643PI and it works perfectly on the Windows 7 partition. Is there anyway to get the card working on Ubuntu without being connected to the internet?
I was trying out the fedora live cd but I couldn't get my Internet to work. When I open firefox it always said server not kind no matter what I searched or put into the address bar:
I tried many different things but none o them worked I am able to ping m router an I'm able to login to my routers page I am also able to login to my modems page and it says connected to the Internet I tried restarting the modem and the router but I still got the same problem I also tried disabling the firewall but still had the same problem I tried a command and I was able to receive packets from google.com, but It never went through in firefox I also tried out a torrent (I had it saved on a USB) and it worked it was downloading fine I am able to ping googles web page but I am not able to search anything.
In firefox preferences and in network proxy I tried many different proxy settings bit none o them worked I always get the message server not found. All this was done while connected directly with Ethernet cable modem and router but untried wireless and it didn't work either on the top right corner of the screen the network icon says auto eth0 active. I'm using fedora 12 livecd.
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
I just recently erased my hard drive and installed ubuntu 9.10 all over again. I updated as expected and everything was going well, until, my internet stopped working after maybe 40 mins or so after a successful boot. Now this same thing happens every 40 mins and I have to reboot the computer by forcing my laptop to shut down by holding down the power button. This also made me aware of another problem when restarting or logging off my laptop. The laptop hangs at that terminal-syled screen and the underscore blinks and fails to shut the computer down/log off. I resort to holding down the power button to restart. I am using a wireless connection with WEP key protection.
Atheros network chip Laptop Acer Aspire 5532 It just happened again..... I am typing now in tomboy notes.... Time to restart again...... I also try to open terminal and it fails to function (after the internet stop working), any reason for that? I would also like to note that the signal strength decreases as time passes by.......
I seem to have is trying to get the internet to work. I can go to ..... ect but when I try to run playonlinux it says you do not seem to be connected to the internet, please post if you have anything useful, as I said I am very new to linux so be as detailed as possible.
Im having problems with Ubuntu 10.04. My wireless disconnects frequently and firefox seems to stop working. it seems the connection times out sometimes when firefox stops. other times the connection just disconnects. When I was running 9.04 everything worked and nothing disconnected, so I know its not my computer.
My laptop is an IBM t40, 1.4 ghz, 2gig of ram.It does not seem to mater if Im using the wireless or the wired connection. The problem happens either way.does anyone have a solution for this?
i did install opensuse and everything ok; i did configure it to be the server and gateway for a little office network Everything seems to be ok most of the time but sometimes (usually between 5 and 7 pm each day) internet stops working and there is no way to let it start again. So i turn off the suse, switch all cables to the old fedora server, just turn it on fedora and internet works. Turn off fedora, connect suse, let it start and everythng ok...it happens all the times
After upgrade from 10.04 to 10.10 on my dual core, 64-bit machine, my miro software has problems downloading torrents. Torrent will start slow and then, after a minute or so, it slows down and stops saying "starting up". It appears there is a bug report, bug 668615, but I've found no fix.
This is my second day with ubuntu on a dell mini 10v with broadcom wireless card. I hooked up to a wired connection and ubuntu installed the drivers for the broadcom card.When I put the cursor over the wireless icon on the desktop it shows the name of my wireless connection,active,and my ip address but when I open firefox I get a "server not found". I'm confused as what to put in the boxes for ssid,mode,bssid,mac address,and mtu under network connections. I've tried pretty much every conceivable method at my disposal,even went on my d-link router settings and nothing has worked.I do not have windows installed,using 10.4
I can connect to my router but no web pages will load etc... I can connect my phone to the router and USB tether it to my laptop and everything works fine. I can also connect to my neighbors router and everything works fine.
I have tried put my routers IP in /etc/resolve.conf but to no avail. I also tried putting 126.96.36.199.
Edit: Toshiba Sattelite A215 laptop (RS690 wireless card?) and a Linksys router.
My PC is connected to an modem (DHCP) with IP 192.168.1.21 on eth0 Internet works perfectly I have installed an additional LAN card and configured it as eth1 with IP of 192.168.0.1 When I connect this LAN card to a LAN switch which in turn is connected to 6 other PCs, the internet stops working. As soon as I switch OFF the LAN switch, I am able to access internet. The IP addresses of the other PCs are configured as 192.168.0.2 etc. with gateway as 192.168.0.1 and DNS same as the DNS on the external interface. I can ping 192.168.0.1 from the LAN but neither LAN nor the main PC can access net. I was planning to Masquerade and NAT the other computers without using squid
My setup is as follows
ISP - Modem(192.168.1.1) - Ubuntu desktop 9.04(external interface eth0 192.168.1.21 & internal interface eth1 192.168.0.1) - switch - LAN (comprising of Ubtuntu 9.04, 9.10, 10.4 & XP machines with IP 192.168.0.2 - 8 and gateway of 192.168.0.1) I did NAT as per [URL] This worked perfectly well 1 day Next day onwards whenever the LAN switch is "ON" the main Ubuntu wudnt get internet and the internet connection would work only when the LAN switch is turned "OFF". Even if all the PCs in LAN were to be switched off, the main Ubuntu would behave similarly i.e. internet would work only when switch isn't connected to it or switched off.
I want to set a up a network of inter connected pcs, for example on pc A linux is installed.now pcs B, C , D, etc should connect to A and do there work, for example A want to do C/C++, development, whereas B wants to do some PERL development or whatever, this is just an example, 2 different pc users might do same work also, and the connecting pcs may have Windows or linux or bsd.OSes now what h/w or s/w is required and what steps are required to set up this network, main pc would be connected to internet and also connected pcs might want to use internet also..have installed opensuse edulife , and use this as PC A for testing.. and I use bridged dsl Broadband connection to connect to internet , by the username and password provided by the ISP, in windows its easy to setup this connection, however not able to do on linux,
I just got a new power supply in my old desktop, and installed ubuntu on it. I've got three NICs in there (for a later project), and when I connect my cable modem to any one of the NICs, then little connection triangle-spinny-thing in the upper-right tries to connect. But it never gets all the way connected.
just installed Ubuntu Netbook remix on my acer aspire one, and come across a problem Ive never faced before. Im able to Connect to my router (and access it through the internal ip address) but as soon as i try access anything outside of my network there is nothing!
This i found odd as first i thought it might have just been my Routers problem, but seeing as all my other computers were connected to it with no problems (wired and wireless) I quickly traced the problem back to the laptop.
After this i decided to see if after a simple update would fix the problem. so i connected it up through the Ethernet port once again it connects to the router but no internet! I have tried everything in my knowledge, but with no success!
I can connect my wlan card to router (gateway) ,but I can't go to internet, pinging my router (and everything else) also falied. Same problem was with knoppix but with help of others i solved it modifing etc/reslove.conf IP address to my gateway (nameserver). At ubuntu resolve.conf seems ok, as there is already IP address of my gateway?
I am connected to my wireless network but can't connect to the internet. I have searched the ubuntu forums for solutions but none seem to work for me. I can post terminal outputs if required (I know that much).
I have installed ubuntu a few times in the past but if I've had to get messy with the command line I bailed. So given that I wanted to set up a home server/media center, I tried win server, but given research had told me that it is easier to accomplish all the features I wanted with Linux I decided the time had come to really see what I'd been missing out on. So what I am looking to accomplish is a full lamp stack, xbmc, samba, mail server, VMWare server, rtorrent, ftp, an probably a few others I have forgot because I can't get to my check list right now. Settled on ubuntu 10.10, had installed it a couple of times while it was still in beta, just to get a feel for it and get everything working so that when it was released I could do a fresh install knowing how to configure everything.
So on Sunday the time came. Everything was going fine until last night, I was installing roundtable webmail and all I came to download something and FireFox can't display any web pages, postfix can't deliver mail. The server can ping local machines but not google.com or another internet site, I can ssh into it an get a remote desktop session via various methods, both either over the local network, or internet. The website is getting served both locally or internet. I just cant seem to make any outbound connections to the outside world.
Im using a laptop with a wireless card inside it is a Realtek RTL8187B network adaptor. I go to wireless connections in the toolbar at the top of the screen and click on my internet modem and it says its connected. So I go to firefox and it brings up google. I try and do a search and it says something and at the bottom of the page it displays a button that says "Try Again". Im booting ubuntu from the cd drive so its not installed on my computer what should i be trying?
I have an old GX 159 Dell Desktop I tried to install Ubuntu 10.10 on it and it worked like charm the problem is when I connect my Alfa 1 wireless adapter and connect to the network it won't let me connect to the internet. Well I have been succeeded to connect to the weather center, but I can't update or open the Internet even if I have been able to open Hotmail.com after 2 minutes it won't open anything after that
Note: I didn't install the driver for adapter and I don't know how to do it because I tried before and I failed adding I used it on more than one distro. By the way it works perfect on Windows?
On the 25th of January, one of my computers randomly stopped being able to connect to the Internet. It was running a dual boot (Ubuntu 10.04.1 LTS & Windows XP SP2), and is connected to the network via an ethernet cable (no wireless). According to the Network Manager, everything is working okay (there was no change from when I was able to access the Internet).
When I would use Firefox, I would get the message "Waiting for (page)...". However, this is not a Firefox only problem, as every program requiring Internet access (e.g. Evolution) is unable to connect to the Internet.
I compared the Internet settings to those of my father's Windows XP SP1 computer, which is able to connect to the Internet. There was no difference, except for the IP Address and Hardware Address. Because of this, I incorrectly deduced that either the actual Ethernet cable or the wall plug was faulty. I tried using a different cable and connecting to the Ethernet wall plug used by the aforementioned computer. Nothing changed. I was still unable to connect.
I didn't worry about it until Tuesday, when my other computer had exactly the same problem. It is running a triple boot between Ubuntu 10.04.1 LTS, Ubuntu 9.04 and Windows XP SP2, and I am unable to obtain Internet access using any partition. As with the previous case, my computer showed no change in the Internet settings, and the computer also shows it as being connected to the network. It is also connected via an Ethernet cable.
I have a Toshiba Satellite L505D-GS6000, and I installed Ubuntu before and it worked flawlessly until I decided that I had to go back to Win7 because of certain program compatibility issues.I'm back here trying to set it up and am having no issues except for with my wireless. I can see all of the SSID's, I am able to connect to my wireless, and it displays that I have been assigned an IP and all of the other settings given by DHCP.
I have been trying to fix this for hours, googled, searched these forums, and have spent time with some people on the Ubuntu IRC channel and we are unable to come up with a fix.
The strange thing is that although nothing will load when I try to visit facebook.com, google.com, or any other website... I opened the update manager and I noticed that it would download for 30ish seconds, stop and do nothing for 60ish seconds, resume for another 30, stop, resume, etc. until it finished. I am able to ping my router, and 188.8.131.52, but I am unable to ping [URL].
I'm running a Natty machine wired to a TP-Link router (TL-WR841N) with additional Ubuntu and Windows machine on WiFi. Recently I've had some problems with connectivity on the Natty machine. Connectivity is fine as far as the router, but not beyond it. This applies to all browsers, Software Center, Aptitude and anything else you can think of. Now, normally at this point I would call my ISP, but the thing is, all other machines have connectivity. I've checked the cables twice and anyway, if it were them, I wouldn't be able to ping the router. Router has ping functionality to outside and it's working, have tried ubuntu.com and google.com. Also, connectivity between the wired and wireless machines is fine, pings are flying across the network beautifully.
My PC is connected to an ISP with IP 192.168.1.21 on eth0Internet works perfectlyI havenstalled an additional LAN card and configured it as eth1 with IP of 192.168.0.1When I connect this LAN card to a LAN switch which in turn is connected to 6 other PCs, the internet stops working.As soon as I switch OFF the LAN switch, I am able to access internet.The IP addresses of the other PCs are configured as 192.168.0.2 etc. with gateway as 192.168.0.1 and DNS as the ISP DNS.I can ping 192.168.0.1 from the LAN but neither LAN nor the main PC can access net.I was planning to Masquerade and NAT the other computers without using squidMy main PC runs on Ubuntu 9.04 and out of the 6PCs on LAN, 2 are on Windows XP, 1 on Ubuntu 10.4, 1 on
