Ubuntu Networking :: AR5001 Chipset - Wireless Networking Randomly Loses Connectivity And Can Not Regain Connectivity
Jun 25, 2011Wife's laptop has AR5001 Wireless Adapter laptop model is Toshiba Satellite A215
Problem : Wireless networking randomly loses connectivity and can not regain connectivity, the only apparent solution is a full power down , this is not even certain to work. The card works under Windows, she hates Windows. (I love her for this) I know it's not faulty hardware , because it will work for days on end under Windows without problems.
Things I've tried : madwifi drivers (any and all versions available) : These increase stability of the signal and seem to delay the inevitable however it still happens. When using these drivers the only option is to unload them modprobe -r then reboot then remove them again and re add them. It makes no sense why this works, and if I don't remove them prior to rebooting it will not work.
ATH5K drivers : These are pretty much junk, results are unpredictable at best, sometimes it will work perfectly for a few hours, sometimes it will not work at all. Nothing is repeatable, I can't seem to force whatever condition is causing this. rfkill does not show the wifi being blocked (hard or soft), unblocking it anyway does nothing, only way to make this work and it's iffy is to fully power down wait 5-10 minutes turn it back on and it MAY decide to work.
Firmware update : Updated the Toshiba BIOS to the latest version of the firmware 2.0 no joy here either. Same issue both sets of drivers.
Tried different distros and kernels : I've tried Mint 9, 10 ,11 ; Ubuntu 10.10, 10.04 , 9.10 and 11.04 (which is currently installed) , Fedora and OpenSUSE. All are giving the same problems. I have also tried a slew of different kernels no joy from any of them (I'm not at the computer with the issue now I will post exactly what kernel versions I've used when I have access to the machine).
Another useful bit of information, the hard switch to disable/enable wifi WILL disable it but turning it back on does absolutely nothing. The hotkey does nothing at all. The bios does not have an option to disable or enable the wireless card.
I will also post the typical lsmod , lspci , iwconfig all that good stuff when I get back to the computer in question. I'm probably just going to buy a PC card for it and give up on that one, but this is driving me insane and I would really like to see it resolved even if I do replace the hardware.
Ubuntu Networking :: Browser(s) Not Working Properly?
Mar 20, 2010Alright I just installed Linux as the only and got it all set up but now I have a problem with firefox or actually any browser. As far as I understand my internet works fine, I was able to download updates from the software center and various programs too. My problem is that when I try to go to any other website than google the browser just freezes up. The bar in the left bottom corner just says "Waiting for <site name>" Strangely google and google mail works. Ive tried going through all of the network settings but I am at a loss now

Jan 27, 2011I have a dual boot (XP Pro and F13) laptop. This laptop has a Ralink RT2501USB Wireless Adapter which works perfectly fine on XP. But when it comes to F13, adapter only works properly when I am physically next to my router. When I move few feet away the strength of the connection drops from 100% to around 40%. But even though 40% should be okay for slow connection to internet, I can't get any internet access at all. I have tried three different routers with same results on each.
When I boot same machine with windows XP, all works fine. I can move to any part of my house and I will still have the connection without any issues.I can see that RT73 driver is installed if I check in add remove program under system.I am not an expert but to me its seems that the drivers on F13 for RT2501USB are not as good as on windows?
Ubuntu Networking :: Weird Network Is Not Working Properly
Apr 18, 2010I have just recently installed Ubuntu karmic on one of my machines. The network worked perfectly until today, when it just wont connect. I have double checked that the SSID and Password are correct. It is a WPA network. I am sure it is a problem with my computer, not the network, because my brother's laptop (which I am using right now) has ubuntu 9.10 installed on it and the network is working perfectly.

Sep 12, 2010I use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Fedora :: Checking If OpenGL Is Working?
May 31, 2010I'm trying to get a program to compile with OpenGL support and it's saying that the headers are missing. But I think (or thought!) that I already had Open GL up and running. My suspicion is that I need to install the appropriate -devel files...but I just can't seem to find them. Furthermore, I don't want to tweak my system and install proprietary Nvidia drivers if things are already working just fine.
I have a Geforce 8300 GS in a i586 32bit Dell Inspiron 530. I'm trying to compile Cinelarra and keep getting:
Quote:
OpenGL 2.0 libraries missing Hardware acceleration using OpenGL 2.0 is disabled
Does anyone know which driver (ie: 96xx? 173xx?) I should be using for this? Where are these libraries? How can I find them and tell Cinelarra where to look?
And even more basically: How do I tell if OpenGL is working or not? Maybe I don't have them afterall..

Ubuntu Networking :: Dual Ethernet Networking - Lose Internet Connectivity?
Apr 18, 2011I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.

View 2 Replies View RelatedUbuntu Networking :: Different Connectivity Under Different Kernels?
Apr 19, 2010I use a laptop with a built-in WiFi card (Intel PRO/Wireless 3945ABG [Golan] using iwl3945 module). It's OK but sometimes is not very stable, occasionaly it simply dies and I have to reboot. It was even worse but I improved it by applying a new driver.I also have a very nice USB WiFi card (D-Link System DWA-140 802.11n Adapter [ralink rt2870]). It's much better and faster.
So the problem is that in Ubuntu 9.10 (2.6.31) I can use only the built-in one. The other one (D-Link) also works but I can't make it connect to my router. The built-in card connects to it but the D-Link even does not list it among possible connections (but it lists other possible connections which I do not want to use).The funny bit is that this problem disappears when I use an old Kernel (2.6.28-18 ) : both cards work fine and can connect to the router at the same time (obtaining different ip's). I then disable the built-in one and happily use the external card.
Unfortunately the old Kernel has issues with sound and video, so I would like to use the latest Kernel with the external card. I tried WICD but it didn't change anything.I can add that under the old Kernel the USB card is used as a ra0 device while the new Kernel lists it as wlan1.
Ubuntu Networking :: DWA 547 Connectivity Stability?
Apr 4, 2011I have an issue with my Dlink DWA 547 802.11n PCI adapter, I'm under LUCID fully updated.I have no trouble connecting to any wireless but after a few minutes I'm loosing the connectivity strenght (getting ping reply from my router that vary from 2ms to 200ms). But as soon as I'm rescanning the network using the command (sudo iwlist wlan0 scan) everything is fine (constant 1-2ms ping). I'm using wicd as network manager. I have tried to schedule a job in crontab to launch every 10min a network scan command, but didn't succeed to have it working, morehover I don't think that's the good way.

Jan 14, 2011The goal: ipv6 connectivity using 6to4 The problem: no connectivity on some internal hosts (mixed win & debian) and no ipv6-web access on any host. Let's start with my external box. It is headless debian lenny dhcp/local-dns & cache/firewall. It has the following interfaces after a reboot:
[Code]...
My understanding is that ipv6 will auto-configure itself and that the radvd file is all that is needed by the external host to give all the ipv6 enabled internal hosts ipv6 web access. My question: How is my external host misconfigured? Or are the problems specific to the internal hosts? I am assuming that I have issues on both the external and internal hosts since some of the internals have golobal ipv6 address and some don't. I do however wish to address the external host first.
Networking :: Connectivity Stops On Fc12?
Jun 9, 2010I am installing fc12 in a datacenter that does not yet support fc12. I have fc12 successfully running on several other machines in a different unmanaged datacenter. Here is my problem. After booting the machine I run a data transfer intensive operation. I use scp to transfer a 1GB file. After some percentage, 10 to 30, the network appears to go away. No ping, ssh, traceroute, etc are successful (in or out). At the KVM console I can check the status of the network service, it indicates its up. Restarting network, turning off iptables, ifdown/ifup do not have any effect. Only a system reboot will temporarily allow network connectionifconfig show LOTS of RX errors and dropped packets.

Jan 13, 2010Machine 1) I have a Server with RHEL5.
eth0 = 192.168.48.x (static class C ip connected to VLAN switch)
Internet available via HTTP proxy through vlan but from other main server but not from machine below.
Machine 2) I also have a Server with RHEL4.
eth0 = 124.30.XXX.xxx (public IP for availing internet)
eth1 = 192.168.60.xxx (class c ip to share internet via squid on the same LAB)
eth2 = 192.168.16.xxx (class c ip connected to VLAN switch)
Now what I want is ssh connectivity available to Machine 1, so as to enable remote machines on the internet connected. I know that it might be hard for Machine 1 to share ssh directly on the internet but if there is any kind of tool or tricks to setup pls tell. So the only chance is ssh via machine 2 then after connected to Machine 2 then again ssh to Machine 1. But how do I make ssh available online? IPtables are set correctly machine 2 can't be ping on the internet.
Networking :: Get WIFI Connectivity To Board
Mar 28, 2010I am working on a project to build an embedded board with WIFI connectivity. My present status:
- I have a embedded development board TS7200 .
- It has USB and Ethernet Port.
- I am able to get port Linux on it and run program to communicate between devices and a computer using socket programming and Ethernet.
I need help in deciding how to get WIFI connectivity to the board. I guess it would mostly be using WIFI dongle? Any suggestion for a WIFI dongle?How should I get it working? Where should I look for proper reading material? I am am planning to do some basic program practice using WIFI on my laptop. How can I do that ?
Fedora Networking :: How To Enable TCP / IP Connectivity With XP Machine

I have a type of middleware server running on the linux machine and I want to be able to run the client for the application on the windows machine and work that way. I have heard Samba as a solution but my understanding is SAMBA is mainly for file sharing.. and is not necessary for establishing TCP/IP connectivity. Is this a correct statement? How can I go about setting up TCP/IP connectivity between the two machines?

Oct 11, 2010May I please have some help configuring wireless connectivity?I just moved and went from connecting to a LAN infrastructure to connecting with a wireless cable modem. The modem is dual-purpose, it has two ports, one for an Ethernet cable, and an access point for a wireless connection. The ISP is CableOne. My laptop, which I use most often, is wireless capable, and I want to use the wireless feature. The laptop is running Fedora 13 KDE, with a VirtualBox virtual drive running WinXP.
I have used NetworkManager to create a wireless connection and name it. I have also used WPA encryption for this because I don't want anybody else using my bandwidth. Moreover, I have tried no encryption and WEP, all to no avail.
