General :: Losing Wireless Connection After Switching Back To Vista OS

Feb 17, 2011

I have Ubuntu 10.10 installed. I am very new to Linux. I am having a problem connecting to wireless network when I reboot to Vista OS. When I am using Ubuntu, it works fine. I have to plug in the LAN cable in order to connect to internet. When I try to connect to wireless network, I don't see any networks at all. My WiFi switch is ON. I keep switching back and forth between Vista OS and Linux.Narendra

Ubuntu Networking :: Losing (dropping) Wireless Connection After Changing MAC Addr?

Aug 8, 2011

Sorry if this has already been solved;answered anywhere else - I tried looking it up but to no avail. The problem persists & the hints I found around the forum did not provide a solution to the case, neither other net solutions i looked up I run Winblows at the lab and sometimes take my Ubuntu PC with me. There is an open Wireless network where they set MAC permission, and there's no pwd to access. It so should be fairly easy to change m MAC and access it, right! No. I run ifconfig and macchange, successfully change my MAC addr BUT the connection drops! Then if I change it back (MAC to my original address) it goes back online. And yes, I shut down the service -- "ifconfig wlan0 down" and then up..WHAT ON EARTH am I doing wrong??? No webpages touch this 'trouble-frigging-shooting instance!

General :: Switching From Vista - On Sony Vaio ?

Dec 18, 2010

I have decided to switch from Vista to Linux on my Sony Vaio and wanted to know the best way to do it.

Basically i want to set my laptop like this because i want to get involved with wireless security testing.

I am thinking about taking the Backtrack wifu course

Now obviously it seems i will need Backtrack, so what is the correct way to go about installing? Should i try and purchase a cd to install or is there better ways?

Cannot wait to move away from Vista. I think it has been making me ill. ps.. i also want to learn BASH and Perl, so that is basically going to be the setup.

Fedora Networking :: Deleting A Wireless Connection / Can't Get Back Onto Network?

Jun 14, 2011

I was on my wireless network when I accidently switched on "airplane mode". Several reboots later and I can't get back onto my network. It keeps prompting for a password, even though it's the correct password. I've booted into Mac OSX & Windows on the same laptop and they connect no problems.

How can I delete the network connection to take it from the top again ? You used to be able to right click on the network connection in F14, select "edit connections" and then delete anything that was offending. That seems to have been removed now though ? Where is it stored and where can I kill it ?

General :: Adding Memory From Dedicated Kubuntu Partition Back To Vista

Jan 16, 2010

I decided to remove my Kubuntu partition until I can fully dedicate my time to figuring out linux (right now I need Windows for certain things, i.e. flash and my zune).

I fixed the MBR, but the problem now is I have a 142.77 GB partition of free space. What do I do? Do I just delete it?

When I click delete this is the message I get:
"This is an Extended partition. This partition will become inaccessable if you delete it. Are you sure you want to delete this partition?"

I am essentially asking if this just means the partition will be gone and not the memory, and where the memory goes if I delete the partition.

Fedora :: VLC Media Player - 14 - Rolling Back To V.13 Without Losing My Configurations

May 2, 2011

Before upgrading from Fedora 13 to v.14, VLC Media Player (v1.1.9) worked perfectly. But under Fedora 14, when I try to use it to play .AVI files that played perfectly under Fedora 13 (with the same hardware), VLC opens, stalls for a second, then closes. I've tried several files -- all of which play under Movie Player (and DID play on VLC under Fedora 13), so I know the files themselves are valid. I'd like either to have VLC work under Fedora 14, or revert back to Fedora 13 and permanently block any future upgrade to 14. easy way of rolling back to v.13 without losing my configurations or any of my installed software? Would using a Fedora 13 CD do it?

General :: When Switching From Mint To Windows - 70% Of The Time My Wireless Stops Working

Feb 5, 2011

I am currently dual booting between Linux Mint 10, and Windows Vista SP2. Wireless works fine in both these OSes, but when I quit Mint and load Windows, 70% of the time my wireless stops working.

ie, it does not detect any wireless networks nearby, althought there are tons of them.

Restarting the wireless device doesnt help, I have to restart my computer at least 4 times for wireless to start working again.

And as of now, my wireless in Linux Mint has stopped working.

Networking :: Keep Losing Internet Connection

Feb 16, 2009

I'm using Xubuntu 8.10, network-manager, Atheros AR2413 802.11bg NIC, and Radeon Xpress 200M with open-source ati drivers.

My problem is that I'm frequently losing my internet connection--whether I'm wired or wireless. It happens most often when I'm watching a ..... video but it happens other times too. My cpu usage is high when watching ..... (70-100%), so that may have something to do with it but I'm here because I really don't know.

I started having this problem when I switched from the proprietary fglrx driver to the ati driver. I switched because my laptop was always freezing halfway through a movie using vlc/mplayer. The ati fixed this but gave me my current problem. I do not want to go back to fglrx.

Here's what I've done so far to try to fix it without success:

-tried using noapci boot option
-tried using a different router
-tried using wicd

When I lose the connection I still have a strong signal. My lshw and iwconfig outputs are the same as before I lose my connection. However, I cannot ping my router when I lose the connection. I have to reboot to reconnect.

Debian Configuration :: Static IP Switching Back To DHCP

Jul 15, 2010

I'm new to the forum and actually to Debian as well. Have been running Ubuntu for the past few years. Just setup a small Dell laptop to use as a Squeezebox and Print server. It's been up 6 days without a hitch as far as serving music to the squeezebox and printing. The problem is that it loses it's static IP, so as long as I look it up and change the radio Squeezebox and printer definitions around on the clients everything keeps working.

Does anyone have any ideas?If the connection drops for some reason and the system has to re-initialize the connection, shouldn't it use the /etc/network/interfaces file and get back to the static IP that it is configured for?If anyone has any ideas of why this could be happening or have a solution, I would really appreciate the help.

Ubuntu Networking :: Losing SSH Connection When VPN Is Activated?

Jul 6, 2010

A friend of mine is running Ubuntu. He used to run Windows XP, but he kept destroying it completely, and I soon got tired of fixing it for him. So I setup Ubuntu, and we're both happier people for it.BUT! The other day he asked me to setup a VPN (PPTP) connection to his workplace, which I promptly did. It also just works, except for one minor problem: When he fires up the VPN connection, I lose the ability to connect to his computer over SSH. As soon as he shutdown the VPN connection, I can once again log in over SSH.I use the SSH connection for basic maintenance and for tunneling port 5900 so I can assist him over VNC.

His nic is setup with DHCP. Gateway is Port 22 is NAT'ed to, which is the IP his computer is assigned by the router (it's reserved to his MAC address).

When he connect the VPN, a new interface is created with the IP I'm very much _not_ a network expert. I can manage the very basic stuff, but beyond that I'm quite lost.

Debian :: Losing Connection With SSH And Webserver With Lenny

Aug 13, 2009

I'm not sure if it is the connection I'm losing or something else is happening and I just can't fathom it out.

I have set up Debian from netinstall. I installed openssh server and Apache. The server is connected to our local network with the IP address and shares a physical port on a simple ethernet switch.

I can SSH into the server from Ubuntu but it takes around one minute to ask for a password and another 20 seconds or so to bring up the prompt. I have checked twice to make sure their are no conflicting IP addresses on the network (all static). The connection seems fine but if I am away from the secure shell for more than a couple of minutes or I minimize the terminal window I can no longer type anything at the remote machines prompt. Reconnection without restarting the server is impossible on most attempts and the terminal just hangs before the password prompt appears.

I have the same kind of issue with Apache. I can view Apaches test index.html using just the IP address from my browser but after a few minutes I get the 'connecting to' in the status bar and it never reconnects.

Ubuntu :: Artifacts Left On Desktop After Switching To Awm Then Back To Gnome

Aug 13, 2010

I recently tried out the awm version of the desktop environment. When I switched back to the Gnome desktop, I found a couple of titlebar-like artifacts left on the desktop.I did some experimenting, using System Monitor and the Kill xxxx command and managed to rid myself of one of the artifacts. The remaining artifact can be taken care of by using kill xxxx comand for the gtk-window-decorator but, this basically renders window buttons useless after the command is issued.

I think I had a couple applications running at startup in Gnome desktop before I switched to awm, and they didn't start at startup when I returned to Gnome desktop, but the titlebar-like artifacts did.Is there a way to reset the state of the gtk-window-decorator in a manner that is less destructive, and which allows my desktop to be clear of this artifact?

Ubuntu Networking :: Losing Internet Connection At Random?

Feb 2, 2010

I am running Karmic AMD64 on a homebrew desktop PC, but I also previously had this trouble on 32 bit with different hardware and on Ubuntu 9.04 and 8.10. The router is now an ADSL+ Thomson TG585n supplied by O2 and badged O2 Wireless box III. The PC has a direct ethernet connection. The router was replaced by O2 when the problem first appeared, as the Wireless box II was suspect. However, I still have the problem and it is getting more frequent.

The symptoms are these: I generally shut down the PC each night, and only fire it up again when needed, which is usually the following evening, but it remains on for most of the day at the weekend. Very often when started, I find I have no connectivity to the internet, and cannot retrieve my emails. Strangely though, the Skype connection is still present and works, although not every time. My wife's laptop is connected over the wireless link - and that STILL WORKS! Sometimes I can connect to the router interface, but sometimes I can't. I've never lost the connection while the PC is running.

I have tried everything I can find in the router (when I can connect) and also in the Systemreferences:Network Connections and also in System:Administration:Network Tools, but can't find anything that helps. A re-boot of the PC doesn't help. A re-boot of the router doesn't help. A hard reset of the router on it's own doesn't help. The only solution to restore the connection is a hard reset of the router (using the recessed reset switch in the back) followed by a re-boot of the PC.

Since the Skype service remains working, and the lights on the router remain normal and wireless service doesn't fail, I think this has to be a DNS server problem. In the previous release, Jaunty, I changed the DNS service to OpenDNS within Ubuntu, overriding the router's settings. That seemed to help a great deal, although there was still the occasional outage which might have been another cause. I can't find anything in the GUI interface in Karmic that will let me do this, and I can't now remember how I did that in Jaunty.

Ubuntu Multimedia :: Losing The HDMI Video Connection?

Sep 15, 2010

I have a Zotac MAG HD N01 desktop computer hooked up to my 40" LCD Samsung TV in the living room. On this machine, I have Ubuntu 9.10 minimal installed, and the system is configured using the XCI script (a customization script to configure the system as an HTPC with XBMC).

Now, since the original install, I've tweak it a little, and one of the things I have it doing is its booting into a minimal desktop using the NODM login manager and it goes into OpenBox. Everything works fine and dandy, however, when I leave it for a while, it looses its connection and says "Searching for Signal" on my TV. I can remedy the situation by just hitting a key on the keyboard (Ctrl for example).

This also happens if i'm watching, say a flash video in a web browser for a while (like a hockey game), and all of a sudden, the screen cuts out.I've checked in the openbox configuration, and screensaver is turned off, but I can't seem to find where to configure any sort of power management. Is there a way to turn off the, what I can only assume, is a power management feature?

Ubuntu Networking :: Losing Wired Connection Repeatedly?

Nov 1, 2010

I did a clean install of 10.10 just under a week ago and something is really wrong with my wired connection. I keep loosing all connectivity and have to connect again from the panel app. After that, every thing works again for about 30 to 60 seconds and the the connection goes again. No lost connection notification pop up or anything like that, but i cannot browse the web or download upgrades while the connection is gone.

Then the really weird part. Sometimes my connection works just fine. On some boots everything is fine for a long time (hours?) but then the problem comes back. My network card is an Intel 82567LF-2 and it uses the e1000e kernel module. I dual boot to Windows Server 2008 R2 and there I have full connectivity all the time.

Networking :: Keep Losing Connection On Ethernet Card With Public IP's

Feb 11, 2009

I have a very strange problem with my Linux Router/Firewall machine where i keep losing my connection on the ethernet card.

I have installed a Debian 4 distro on a PC with 2 nics to create a router/firewall machine. On nic-1 i have connected the ADSL modem and on nic-2 a laptop for testing.

What i want is to build a DMZ with public IP addresses assigned to the servers in DMZ.

Schematic example:


We have a total of 16 Public IP's assigned to the ADSL modem from our ISP configured in routering mode. Unfortunately our new ISP does not support Bridge mode, otherwise i would not have this problem. (we had modem in bridge mode working fine with our old ISP, but they have stopped so we were forced to switch to another ISP. eth1 and eth2 both have public IP addresses from the modem set hardcoded in the /etc/network/interfaces on Linux pc and on my testlaptop in the DMZ (server-1) i have set another public IP (they all fall in the same network range) I have enabled IP forwarding on Linux router/firewall and for testing the firewall is set to allow all traffic.

When i try to ping the testlaptop in my DMZ from a remote machine outside in our datacenter i get no reply.

However when i run the following command: ip addr add xx.xx.xx.xx dev eth1 to assign the public IP i have chosen for the laptop to the inner nic (eth2) and then try to ping the testlaptop again from the remote machine it still does not reply ... but (and here is the most bizar thing)...

When i then run the following command: ip addr del xx.xx.xx.xx dev eth1 (where xx.xx.xx.xx is the ip of the testlaptop) and try to ping again from the remote machine then it seems to be working fine ... however only for a short time because then connection is lost somehow.

SUSE / Novell :: Open 11 Losing It's Net Connection - Particularly When Using AMule

Dec 3, 2008

I have been using Open SUSE 10.3 for about a year now and have been very pleased. I am now trying Open SUSE 11, it seems good, loads a lot faster than 10.3 and seems to run a little faster. I have had a few probs but they have been resolved with help from these forums. But I have a big prob remaining and I have no idea what could cause it. For no apparent reason I will lose the connection to the net.It happens mostly when running aMule, it can be downloading fine for some while when suddenly the connection to the servers is lost and it won't reconnect, and then also I can not connect to the net with Google etc. The only way to solve it seems to be to shut down, wait awhile then reboot. It will be OK for a while then the problem re-occurs. There does not seem to be a problem with anything else on the system. I know that the Modem is OK as I have three HDD - 1 running Win XP, 2 - running Open Suse 10.3. 3 - running Open Suse 11 & the prob only occurs with SUSE 11, I do not get this problem with either of the other HDD. I have tried three versions of aMule, with SUSE 11,the one given on YAST - v2.2.2-0, & others from Packman v2.2.1-0, & vSVN, the problem occurs with each version so I think it must lie with SUSE 11. I have opened ports 4662 & 4672 on the firewall, & the setup I use is identical to the one on 10.3 which works faultlessly. I use a NTL Modem connected to the PC via Ethernet.
