Ubuntu Networking :: Wifi Fails On Only One Of Two Machines?
May 30, 2011
My netbook runs 10.10 and my desktop runs both 11.04 and 10.10 atm. My netbook can connect and stay on the internet, but my desktop (in either version) connects for ~ 5mins then stops working without warning. It says I'm still connected, but I can't ping anything on or off the network.
My wireless card has always worked fine with every other wifi. Just not this one.
My Realtek RTL8187 Wifi fail to connect using WPA security. The authentication window shows up repeatedly every time I try to connect. Please note the password is correct. I searched and haven't found a conclusive solutions as of yet.
Has anyone else experienced a failure to connect to a mobile network. I have root access wireless tether on my Droid X and I can't seem to connect to it. It times out. My buddies windows box can, and his Iphone will as well. I can see the network just fine, just no connection. Tried changing frequencies as well. And restarting both the phone and laptop.
I am running Ubuntu 10.04 on a PackardBell notebook and have just got an Orange Livebox 2 for broadband connection(after years of dial-up as no adsl in my area).I am trying to connect via WiFi to the Livebox to configure, but neither NetworkManager nor Wicd will connect. NM sees the Livebox but simply fails to connect after trying; Wicd says "Bad password".The WPA2 password I have entered is definitely correct, and I have connected without any problem from an AcerOne under Linpus.I have also tried to connect using Wicd and an ethernet cable, and this doesn't connect either, returning "Connection Failed: Unable to Get IP Address"
I've been installing multiple versions of ubunutu over years and now I better understand why I faced always problems with wifi configuration on these different baselines : Debian root of course.
Now on Debian 7.4 : The Broadcom BCM4313 driver is not loaded by default (not free product) for my wifi card. This is stated thru the UNCLAIMED declaration
My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.
I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

Installed ubuntu 9.10 dual boot with win7 yesterday. Everything working but Wifi. Wifi works fine with Win7. No Wifi in Ubuntu. Very confused. I have info from the wifi trouble ticket post.There does not seem to be a driver for this card anywhere.

I have a pc which has 2 network cards, 1 wifi and 1 ethernet card.
I'm using wifi card to connect to wifi network (internet) and i'm planing to share this wifi/internet connection via ethernet to wireless router (siemens sx763) so i can have internet on my other devices, e.g. mobile phone, laptop.
Recently I updated my openSUSE 11.2 and I'm not too sure what all were the recent updates but I suspect networkmanager also got updated. After I restarted my machine, my laptop fails to connect to the wireless access point. I tried both in gnome as well as KDE but the same error. This is the log I found in my /var/log/NetworkManager which I believe should give some pointers.
I did a search of this error in google and all I got were few results which complained about bugs in some debian distro.
My wireless card works fine and so does the access point I try to connect to since my Ubuntu installation is able to connect fine as well as my windows Xp.

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:
Code:
I notived the following problems in /var/log/kern.log
I have 2 connections, wlan and wired, and I'd want to have a few websites (in my browser) to connect through the wireless connection while other go through the wired rj45 connection. s it possible? (without unplugging the rj45 cable...)
the only error message I can find comes from "dmesg|tail"all it shows is "no IPv6 router"any body know what is going on here or where where to look for more clues the next time I get around public wifi Oh the windoze washers and apple polishers don't seem to have any problems at all
Ive managed to install samba, I've shared a folder. I can access from a Windows 7 machine via \ubuntupublic. I can put files in the folder form the ubuntu machine and edit them on the windows box. I can put files in the folder/share from the Windows box but then I cannot edit them on the Ubuntu machine (they are read only and have a "Lock" over them). I can fix this by going to the properties of the file/folder in Windows and manually assigning "Everybody" full control (then the lock disappears and all is well.) I want read/write access to all the folders contents from both machines all the time (security is NOT a concern I WANT the permissions wide open) what am I doing wrong?
I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
I wanted to be able to have separate NICs with separate IPs connecting to separate gateways on a machine so I could put an ftpd on each one. I tried binding an ftpd to each, and running separate instances of the ftpd. I tried virtual hosts.
NOTHING worked. I could either use one ftpd or the other. I could either connect via ssh on one IP or the other. the second I turned one NIC off stuff would work again. I messed with basic iproute commands, andnothng worked until I got this script to run, which allowed me to use each NIC independant of the other.
Code: #!/bin/sh #ip route flush all ip route del default dev eth1 ip route del default dev eth0 ip route del table 1 ip route add table 1 to default via 10.10.10.1 dev eth1 code....
But now, samba client doesn't work. cifs mounting doesn't work either. It can't connect.
BEFORE I ran that script, I could connect via ssh, or to the ftpd running on the machine using a LOCAL IP - 10.10.10.2. AFTER, I have to use the external IP, or I cannot connect. I know that has something to do with it, but I do not have the advanced linux routing knowledge to redo the script or come up with a solution.
Networking on Fedora 11 doesn't work for me on various machines. Fedora 10 does, but only if you don't do an update.Why does Fedora get worse the more you keep it up-to-date?
I've got a desktop running 10.04 64bit with a broadband connection connected through usb on eth1, I also have a laptop running 10.04 32bit and I've got both connected with a cat 6 crossover cable both on eth0, connected directly without a router. I would like to share files and Internet between the two.
I have no idea how to search this one. I can connect to the internet no problem. I can connect to Windows XP and 7 using
Code: nautilus smb://192.168.0.x
I cannot connect between Ubuntu machines. Which thread am I looking for? I've been using Ubuntu for years, and still do not have a clue about this, but it's not been an issue until my family wants to play games over the home network.
I manage a cluster running RHEL 4. Recently, the head node lost contact with some (but not all) of the other nodes on the LAN. This is very bad because almost all of our data is on an NFS server, so our users can't work until I fix this. The problem apparently started this morning (Jan 19), although there's at least one machine on the LAN that I had lost contact with before then.Here is all the information I think might be useful.From /var/log/messages:
Code: Jan 18 21:45:21 XXX kernel: tg3: eth1: Link is down. Jan 18 21:46:02 XXX kernel: tg3: eth1: Link is up at 1000 Mbps, full duplex.
I may be missing something very easy here, but I have a fresh install of Ubuntu 10.04 64 bit (I have also tried 10.04 32 bit) and I cannot connect to my windows machines. I can't connect by going to the network window, or by connect to server via ip. Basically, I can see the windows machines but then I double click it, and it asks for the credentials. I'm the admin of all of the machines, and I only have one login to my windows machine, which is my name First Last. I am entering this, and my password (which I'm sure is correct) and click "Connect". It thinks for maybe a half second, then presents me a blank credentials box, wanting me to start over.
I can connect to my Macbook without any troubles.
I'm using an Acer AspireRevo 1600, wired connection.
Linksys Router with firewall 1 Linux Server -- Running Dapper Multiple Linux ThinClients running off the linux server Multiple Freestanding Linux Machines -- Running ubuntu variants Multiple Freestanding Windows Machines -- Running windows variants
The issue is that certain websites will not load on the freestanding linux machines, but they will load on our linux server and all the windows machines. examples: [URL].. These sites will start to load, but they never really finish and just seem to time out. I have tried changing the dns on the freestanding linux laptops to use 208.67.220.220 and this does not solve the problem.
I have checked the firewall rules and they seem pretty standard.when the linux machines are used on other networks, these websites work, so the problem seems to be related to this particular network.
When I do (freestanding linux): Code: traceroute acer.com -I The trace times out at 30 hops When I do (linux server): Code: traceroute acer.com -I The trace reaches the destination at 19 hops
Both of the traceroute requests start by going through the router. So the big issue is that websites will load on our linux server and all our windows machines, but not on freestanding linux clients.
Me and my friend have been talking about networking our two machines over the internet. So he has done his side. Now i need to do my side... Any ideas on how i would go about configuring my computer to do this?
I have just upgraded 2 machines to ubuntu 11.04. One was an upgrade, the other a new install. On both machines, I cannot ssh to any machines running Ubuntu 10.04.2 I can ssh to machines running 10.04.1, 10.10, etc. and all those machines can connect to the 10.04.2 machines. I get: Read from socket failed: Connection reset by peer To workaround the problem, I have copied the /usr/bin/ssh on a 10.10 machine to the 11.04 machines.
I have Ubuntu Server 10.04 running as a samba server and a VPN server using PPTPD. I am trying to connect two users to the VPN, which I am running Windows Ultimate on one, and Windows Home Premium.
Connecting to the VPN server from any location, I get an error 619 on the windows machines, and I have googled for what feels like days about the error and can't find a working solution. I look in the /var/log/messages file and see:
Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded. pppd 2.4.5 started by root, uid 0 Using interface ppp0 Connect: ppp0 <--> /dev/pts/1 Modem hang up Connection terminated Exit.
