Networking :: No Connection With WEP Encryption While WPA Works

Dec 16, 2009

There is a strange thing going out there in my box, I've tested b43-fwcutter on wpa-psk encrypted network, and there was no problem connecting (my card is broadcom 4318), recently I was trying to connect to WEP encrypted network without success. Network connection tested on other laptops (Vista, XP machines)so there is no possibility that the key isn't valid.

Ubuntu Networking :: Enable WPA Encryption On My Wireless Connection?

Jan 10, 2010

enable WPA encryption on my wireless connection? Wireless networks are detected and listed, so the wireless card is functional in the most basic sense, however, when going to connect to any particular network,I am not given the option of entering a WPA passphrase, only WEP, and as my router is set to use WPA, this is a problem.I am trying to get this going on a fresh Karmic install on a Toshiba A15-S157 notebook.Thus far, I have found this: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/315489 which would seem to relate to my problem.I looked in my logs and saw this entry: Jan 10 16:06:35 cody-laptop firmware.sh[863]: Cannot find firmware file 'agere_sta_fw.bin', and have since found that file, and have downloaded it to my desktop. It seems like this may be the solution, but how to exact it, therein lies my (momentary) problem.

Ubuntu Networking :: 9.10 Beta - WEP Encryption Key For Internet Connection

Feb 17, 2010

A while back I posted [URL] a question about Ubuntu 9.10 not recognizing my WEP encryption key. The problem that I had is still essentially the same: After upgrading to 9.10 beta, then trying to upgrade using the alternate install disc for the full version (because of the same problem) I ended up having to do a completely new installation. Anyhow the problem still stands: my internet card works and it detects available wireless networks, the only thing is that after entering the key in, it will attempt to connect, then after a min or so, it will ask for the key again, ad infinitum. The upshot is that I can't connect to the internet at all. Right now I'm on Windows 7 RC.

The only thing that has changed is that I tried disabling encryption entirely, and Ubuntu was still not able to connect (I think the connection just timed out after a few minutes). I should add that I have Verizon FiOS, an Actiontec router, and my computer (since it is far away from the router) connects through a Hawking_300N extender. Right now I am using Windows 7 RC (which unfortunately expires in a little over a week), so I can access the internet through Windows, and check for any posts, but I can't immediately provide any command outputs, I'd have to restart, and that would take a few minutes. Further, I have tried both Network Manager and WICD, both of which produced the same results. I have not tried any WPA encryption mainly because the router is shared, and I don't to mess with everyone using the router unnecessarily.

Ubuntu Networking :: Wired Networking - Connection Works But No Internet

Jun 1, 2011

I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.

Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.

The output of some terminal commands are below.

However a pint to that ip address (my router) is successful.

Ubuntu Networking :: Wired Connection Works But Only By Pppoeconf

Jan 3, 2010

It's been a while since i've been trying to deal with this problem but it was useless. I've found many related problems to this, most unsolved and those who had solution wouldn't work for me. I have few mates who have the same problem and still didn't find a solution as well. Here's the problem:

Both on my Desktop and Laptop, the network manager won't recognize that there is a cable pluged on the computer so that it would start my connection. The solution to make it work is pretty simple and its everywhere: use pppoeconf.

Altough that does the trick to make my internet work, i get another problem that i found out to be related to this one, which is: I can't use VPN. Which make me assume that one problem is related to the other, is that on my laptop, which has wireless internet, ubuntu will recognize it and then i can simple use vpn. My desktop, on the other hand, isn't that lucky and does not have wireless, so i can't just use vpn. So far, i've been using vpn on windows when needed, but switching systems is really a pain, not to say i'd rather do that on ubuntu.

Few other suggested solutions were to use 'wicd' and other network managers, altough for some people that did work accoding to what i saw on boards, that didn't really work out for me as well. Wicd coldn't recognize it either. Other suggestion was to check on some txt file on ubuntu, erase few information and let it 'fill up' automatic, it didn't work as well(sorry i don't remember all details on this one).

This problem happened on:
First, wubi for ubuntu 9.04
Ubuntu 9.04(normal install.)
Ubuntu 9.10
Happened both on my Desktop and my notebook, but the same version i installed on both of them were used on other computers and they did work on them so i strongly believe it has to do with the os itself.

Networking :: Wireless Connection Only Works When Close To The Router On Fedora 13

I have Fedora 13 installed on my Fujitsu Siemens Laptop. I can only connect to my wireless router when the laptop is close to it. When I try using the laptop in the next room, it keeps asking for the password and eventually disconnects after 3 or 4 attempts. The wireless connection worked fine in Windows XP.

Ubuntu Networking :: Can't Connect To The Internet When (connection Works Fine In Windows XP)?

Apr 30, 2010

I installed Ubuntu (10.04) today and it has gone smoothly except for the fact that I can't connect to the Internet when in Ubuntu (connection works fine in Windows XP). I am using a wireless USB card (Linksys WUSB600N) to connect.

The weird thing is that the card detects all the local networks, asks me for a password to my network, and it even says it is connected to my network after I put the password in -- but when I open Firefox no pages will load.

There is another weird quirk as well: Ubuntu will not restart or shut down properly (it hangs around indefinitely with the little white / orange dots going across the screen) unless I first remove the wireless card from the USB slot. But that doesn't bother me as badly as the lack of Internet.

I can connect to the internet on Win7 without issue. Boot to Ubuntu 10.10 amd64 & it works sometimes & sometimes it doesn't.

I've attached 4 screen photos; 2 when internet is working (Working ifcomfig & Working route -n) & 2 when internet is NOT-working (NonWorking ifcomfig & NonWorking route -n).

Networking :: Wireless Connection Works But Doesn't Show In Iwconfig Command

Mar 21, 2010

Ubuntu 9.04 with working wlan. I had to restart router & wap. It doesn't seem to ever retry to connect. I know my router & wap are good, I have wireless working on other laptop (running Puppy) I had to go into 'edit connections' in drop down and use 'wireless' tab then edit 'wireless connection 1' and hit 'apply' is there a better way to do this? also, no connections show up with command 'iwconfig' edit: with ifconfig, eth1 si showing data my ip address and packets sent & rcvd. I think I'll try do duplicate this event and use 'ifconfig eth1 down' and then up again to see if it reconnects.

Fedora Networking :: Worthless Wireless Connection \ Works Well For A Few Minutes Then Has A Period Of Inactivity - Then Slow?

Nov 24, 2009

I'm running Fedora 12 on an Acer Aspire One with KDE. The built-in wireless works without a problem EVERYWHERE except at work. It's a shared wireless connection using WPA/WPA2 security.I can connect but it's "hit-and-miss" if I can do anything with it. Somedays it works well for a few minutes then has a period of inactivity - then slow - randomly receives...It worked flawlessly when the computer was running Windows7 no one else has connectivity issues but I'm the only one using Linux.

Debian Configuration :: Networking - Netinst CD - Internet Connection Only Works After Edit The Interfaces And Resolv.conf Files Manually

I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.

Ubuntu Networking :: Internet Ftp "connection Refused" Works Locally

Mar 23, 2010

I am trying to set up an ftp server on my home machine so a friend and I can exchange large files. I have set up pure-ftp server and gftp client.Pure-ftp works fine behind my Dlink DSL 2740B router using host name '192.168.1.100' but not over the internet using host name '80.47.xxx.xxx' I get the message

Quote:

Looking up 80.47.xxx.xxx
Trying 80.47.xxx.xxx:21
Cannot connect to 80.47.xxx.xxx: Connection refused
Operation cancelled

I have set up port forwarding as per the attachment.I haven't set up a software firewall and my iptables -L looks like:

Quote:

$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)

[code]....

The username I am using is part of "ftpgroup" and is the same user that works behind the router.Putting the computer in the DMZ doesn't help.I have a similar problem with SSH so I assume the problem is with the router.Other threads suggest the culprits should be port forwarding or a firewall but I can't see what is wrong.

Ubuntu Multimedia :: Sound Works At First But Keeps Dropping Connection

May 16, 2010

I've installed Lucid Lynx in both kubuntu and xubuntu variants, and experienced the same problem, (Note I'm also still running 9,04,on the same computer, trouble free). With 10.04, the problem is that sound playback software works initially, but drops the connection with the sound driver randomly, at times varying from a few seconds to a couple of minutes. It seems to happen regardless of whether Alsa or PulseAudio is set as default. This happens with Movie Player, VLC, Audacity, and with Flash in Firefox - they all appear to start normally, with sound, but soon fail. (Again, I don't have this problem with earlier releases, using the same computer) I know little about sound configuration.

Ubuntu :: Connection Monitor Script Works Incorrect?

Jan 21, 2011

My promlem is that i wrote a few simple script to monitor the network connection as follows:
script 1 "netmonitor.sh"

Quote:
#!/bin/bash
# /usr/local/bin/netmonitor.sh
ping -c 1 "$HOST" > /dev/null 2>&1
if [ $? = 0 ]; then
echo "`date` Network is ready!" |

[Code]...

Is it possible, that if system don't use the connection after getting the DHCP lease, it close the connection automaticly? Anyway it works ok, but i don't want to owerwrite my router's flash in every 5 seconds with te new lease, my script probably defeat it soon if i don't do anything

Ubuntu Networking :: WPA Encryption Fail?

Apr 3, 2010

I'm on an Acer Aspire One.Clean install of 9.10.I was using 9.10 and my wireless was working fine.Then for no reason it would not connect.So I decided to reboot my router and reinstall ubuntu.Still does not work.I have figured out that it seems to be WPA encryption that is at fault.When I turn it off on my Linksys the netbook connects fine, turn it back on and nada.

if i try to use a static address then the laptop seems to connect but I cannot ping the router or get to the internet.If anyone has any ideas I would be grateful, I would rather use WPA than WEP.My iphone connects and this netbook connects with Windows, so I know the linksys is not at fault.

Hardware :: Eth0 Dead After Power Outage - Eth1 Works But No Connection

Oct 10, 2010

I setup a mythbuntu pc with an onboard card (eth0) so I could watch and listen to movies and music stored on my other pc in the basement. Everything worked fine until we had a power outage. I turned on the pc after the outage and had no networking.

I looked and saw no link lights. I verified the network port but plugging in a laptop. I got an ip and able to connect to the internet so the port is not the issue. I plugged in a pci 10/100 card (eth1) and booted up, got link lights, but no networking and not able to even ping the gateway. I setup a static ip in /etc/network/interfaces and added a route to the gateway/router. Still nothing.

Ubuntu Networking :: Router Encryption Settings 10.04 - Can't Authenticate

Nov 27, 2010

Using a D-Link wireless router, trying to get it through the authentication process with the client through a D-Link DWA-125 USB wireless. When I set encryption to "none" on both ends, the router links up OK, but when I enter matching encryption settings on the router, and then in the driver data file (RT2870STA.dat) on the client side, I can't get it to authenticate. I've tried all possible combinations in the .dat file with no luck. I'm fairly well convinced that there is a bug in the .dat file settings, and that the wireless port setting need to be forced at startup through the /etc/networking/interfces file, or some such procedure, to override the settings in the .dat file.

[Code]..
