Ubuntu Networking :: Can't Connect To New Networks

Jan 24, 2011

I have an hp dm1z and ubuntu 10.10 64bit. After I suspend (close the lid) and wake it up (open the lid) at a different location with a network connection (wired or wireless), my system always fails to connect. I need to reboot and then it sees the network and connects fine. I have tried /etc/inet.d/networking restart, but nothing changes. The only exception to this rule are two networks that have WPA security settings and are stored. I can always switch between those two. I have tried ifconfig eth0 up & down and restart networking. I have also tried to connect manually (dhclient) and no success. None of these work. I am including the output of lshw -C network.

lshw -C network:

Ubuntu Networking :: Can See Networks But Can't Connect?

Feb 1, 2011

I have an MSI Wind U100 netbook running Maverick, and it has a Realtek RTL8187SE Wireless controller according to lshw. My computer can "see" some wireless networks where they are present, meaning when I click on the little network icon at the top of my screen it shows the available networks. But when I click on them to connect, the icon does its little "connecting" motion, but I never receive any message saying "Connected" and when I open Firefox and try to browse to google.com, it says "Server not found"

Ubuntu Networking :: Connect To 2 Networks At Once?

Mar 22, 2011

I have an ethernet card connected to my LAN and a USB cell modem internet connection. I am running ubuntu 10.10. The problem is this: I can use either network, but only am connected to one of them. If I connect to both at the same time my speed drops to zero.f I disconnect one, the other starts working. I have done a lot of searching and reading, but it looks like I don't know how to find what I am looking for.My LAN was setup as 3 WinXP computers peer to peer. One of those computers was replaced by this one that I am having trouble with (computer A). Another one was replaced by one that is not yet on the network (computer C).Computer B dual boots Win XP and ubuntu 10.4. Mostly it ns xp for Quickbooks and BobCAD, also it is connected to the printer. My router is setup for DHCP

Networking :: Connect Separate Home Networks?

Dec 13, 2010

I have my main network with internet and DHCP which is on 192.168.x.x with a router.Now I have set up an Ubuntu file server and i want it on a separate home network with static ip addresses range of 10.x.x.x. and it is also connected torouter.So i will have two networks, one private static with no direct internet access, and the other with internet and DHCP. I want to know how I would "bridge" these two networks so that I could access my file server from the DHCP network. How is this typically done?

Fedora Networking :: Detects Wireless Networks But Cannot Connect?

Nov 29, 2010

Basically, I just installed Fedora in my desktop (use it on my laptop), and have a big problem, which is that Fedora (13), detects my wireless card (Edimax nMAX EW-7728IN), but when I try to connect to my wireless networks (WEP & WPA) it hangs and asks again for the password. I know the problem isn't from my routers,since I'm right now connected via Fedora 13 in my laptop.

Ubuntu Networking :: Can Connect To Insecure Networks / But Not Secure Ones

I recently ubgraded to ubuntu 9.10 from 9.04, but I had the same problem there. I can see the secure connections, but when I try to connect to them, it tries to connect, works at it for about a minute, and then asks for the password again. This just started a week ago or so. I am new with ubuntu, so while I know that there are terminal outputs I should probably post, I don't know which ones.

Ubuntu Networking :: Connect To 2 Networks And Access The Internet?

Mar 4, 2010

1) I connect to the internet on a wireless router from my isp.

2) I use an older router for my media server (pc) to my ps3. The router given to me from my isp is the only one I can use to connect to the internet, yet it has the worst UPnP support (ie: none).

So with this current setup, I have to disconnect from the the wired network to be able to access the internet. So how can I access the internet while still connected to the wired network?

Ubuntu Networking :: Cannot Connect To Unencrypted Wireless Networks

Mar 23, 2010

I have a machine running Xubuntu [2.6.22-14-generic]. I have been trying to get this machine connected to wireless for ages, and I'm having another stab at it. So far I have install ndiswrapper and loaded the driver for a Linksys wireless adapter. The output of 'ndiswrapper -l' reports:

Code:

wusb11v4 : driver installed
devoce (13B1: 000B) present

So as far as my newbie knowledge goes, I believe that step to be completed, correct?When I turn on the machine is type in

Code:

sudo sh
modprobe ndiswrapper

to get the card running to where it will appear in the iwconfig dialog.The commands 'iwlist wlan0 scan' will list all the wireless networks around me, but I have been un-able to connect to any network, even unencrypted ones. I have tried to connect both through Wicd and command-line to no avail. For command-line I have used:

Code:

sudo ifconfig wlan0 down
sudo dhclient -r wlan0
sudo ifconfig wlan0 up

[code]....

With the final 'dhclient wlan0' commands, the following is returned:

Code:

There is already a pid file /var/run/dhclient.pid with pid 134519120
Internet Systems Consortium DHCP Client V3.0.5
Copyright 2004-2006 Internet Systems Consortium

[code].....

I have attempted to go ahead a step further and connect to an encrypted wireless network, however, I receive the same message, as well as another error message upon trying to enter the key, with the following code:

Code:

iwconfig wlan0 key s:"thekey"

Error for wireless request "Set Encode" (8B2A) : SET failed on device wlan0 ; Invalid argument.

Ubuntu Networking :: Wireless Can See Networks But Fails To Connect

Jun 30, 2010

I have an Atheros AR242x card. It can see my wireless network (WPA2). When i attempt to connect to the network it asks for the WPA2 passphrase. After entering the password it begins connecting but hangs up for about 3 minutes before saying wireless disconnected. The wireless worked for one day on a fresh install (Ubuntu 10.04)and then started doing this.

Ubuntu Networking :: Detect Wireless Networks But Cannot Connect

Aug 1, 2010

I have a WLAN Driver Azure Wave AW-NU222 Wireless LAN Card in my Medion computer.

After installing Ubuntu it seems to detect the wireless networks in my area. However, when I try to connect to my network, it tries for several minutes and then times out with no error message. I have set up the credentials and also tried removing the encryption (WPA-PSK) from the network itself, but it still doesn't connect.

Connect via an Ethernet cable is fine, and I know that the network is good because I can connect via my Windows Laptop and various other wireless devices.

I suspect it's due to drivers, but I'm having trouble downloading a driver which I can try and install using Ndiswrapper. The Medion website just a windows executable when I try and download the driver specific to my machine when I really need the .inf file.

Ubuntu Networking :: Cannot Connect To UNencrypted Wireless Networks?

Sep 27, 2010

Here is a situation I have never come across (though I have only been using linux since 2004).I am running ubuntu 10.04 and using Wicd Network Manager.I can connect to my WPA encrypted home network, but if I go to my coffee shop to use their unencrypted wifi - I cannot.Even using the terminal. I think it is the way the device sees the network - but I don't know how to fix it.I have a screenshot with wicd here:And one with connecting to the essid here:Afterwhich, dhclient was unable to obtain an ipaddress - just like wicd above.

My iphone connected to this network easily without encryption or needing to use the browser to authenticate, etc.Any ideas on how to fix this?Specs:Samsung NC10lspci:

Ubuntu Networking :: Unable To Connect To Secure Networks

Nov 12, 2010

I have been using Ubuntu for quite a long time and I never got around fixing this particular wireless problem. I have tried Network Manager as well as Wicd. I am never able to connect to a secure network (WPA). When I use Network Manager, it just tries for a long time and gives up. As for WiCD, it again tries for a long time and finally says "Bad Password". Of course, the passkey is correct. When I connect to an unsecured network, it goes through just fine. I have a Dell Inspiron 1545 which uses a Broadcom 43xx Driver.

Ubuntu Networking :: WUSB600N Unable To Connect Despite Able To See Networks

Jan 3, 2011

I've managed to install my WUSB600N on 10.10 (which was NOT easy!!) and I can see all my local wireless networks, but I can't connect - it attempts to connect then disconnects after what I guess is timing out.I know that you can place these cards in broadcast mode (I think), where you can see networks but not connect. Considering that to get this card working I had to attempt about four different sets of instructions to get this far, could I have placed the card in a broadcast mode? I've been at this for about three days, and unless I go out an buy another network card (I'm currently connected using it through windows) then I'm going to have to give up on Linux, which I really don't want to

Ubuntu Networking :: 11.04 - New Wireless USB - Finds Networks, Can't Connect?

May 20, 2011

So I was the one who couldn't get their ethernet port to function properly. Most likely, this was the result of bad hardware since none of the community's suggestions for software fixes did anything. I believe this is probably true.Indeed, when I bought a cheap $10 wireless USB dongle, it immediately worked better than all the previous things. It detected networks, displayed network strength and even allowed me to attempt login.

The only problem now seems to be that it cannot login. I've rechecked the password countless times, but it just shows the 'connecting to wireless' animation for a minute or two and then poops out and says, 'disconnected'.I assume if everything is getting me this far, the driver is not the problem with the device. Is this a safe assumption?

Networking :: Available Networks But No Able To Connect On Puppy With Broadcom B4312?

Apr 22, 2011

I'm running Puppy Linux from a SD card on a netbook and there wasn't any drivers for the wireless adapter so I went online and found a module for my Broadcom B4312. The module is already installed and when I go to check for available networks I'm able to see my network and a neighbour's network. The problem: I can't connect to my network, which has a WPA2 Passphrase protection. Theoretically this driver won't allow Puppy to link with WPA2 protected networks so I changed the protection to a WEP one and even like this it won't connect.

Networking :: Only Firefox Fails To Connect In Some Networks Using Fedora 14?

May 23, 2011

In all but one place my HP Pavilion laptop running Fedora 14 will work flawlessly to use the Internet for e-mail, ftp, http, etc. In one network there is a wireless router - Cisco/Linksys E3000 - that allows every computer to use the Internet normally for wireless or for wired connections, every computer but mine. If I use Google's Chrome I can access the Internet. I can ping any web site too, but the moment I try to access anything with Firefox 3.6.17 there is a long delay and the standard error page appears. Weather or not I use a wired connection is apparently irrelevant.The Windows 7 computers in the same network are free of this curious problem. Strangely I have noted a problem like this, possibly the same problem, with another network at a coffee shop and they both share the misfortune of using AT&T, which is proud to not support Linux ... for customers of course (it's good enough for themselves I'm sure)

Ubuntu Networking :: Atheros Wireless Card Can See Networks But Can't Connect

May 30, 2010

I've installed it no problems on my desktop and I really love it. Now I'm trying to install it on my Satellite and I'm having a couple of problems. When trying to connect to my wireless network, I can see my network, but it will just keep asking me for my WEP. I've confirmed that there is nothing wrong with the network or the password I've provided. Sometimes when I boot up, the network manager just says that the wireless networks are disconnected and can't find any. The wired connection always works just fine.

Here are the system specs:

Toshiba Satellite M45 S169
Ubuntu 10.04 Lucid Lynx LTS Fresh Install

Ubuntu Networking :: Network Manager Tries To Connect To Out-of-range Networks

Jul 2, 2010

I have a problem with network manager. I use Ubuntu 10.04 on a Dell Latitude D530. I used to have the same problem with Ubuntu 9.10 before I upgraded. I typically connect to two wireless networks: HOME and WORK. Both networks are set to automatic connection mode. I am at work, I connect to the network WORK. At the end of the day, I just close the lid and go home. At home, I open the lid and have the following problem: network manager still displays the network WORK whereas it is clearly out-of-range and it automatically tries to connect to it. It does so until network manager asks if the password is correct.

If I want to connect to HOME, I have to tell network manager to do so. Then, I receive a notification that I am disconnected to WORK. Next morning, I go to work, and I have the same problem, network manager tries to automatically connect to HOME. What I would expect from network manager: when I am at home, NM automatically connects to HOME and does not display WORK, when I am at work, NM automatically connects to WORK and does not display HOME.

Ubuntu Networking :: Won't Connect To Open (unsecured) WiFi Networks?

I have no problem with my wireless network at home, or visiting friends, but it won't connect to public, open, unsecured WiFi networks, eg hotels, trains, ships.I'm using Ubuntu v9.10, NetworkManager applet v0.7.996, on a Dell Inspiron 1750 laptop.If I left click on the NetworkManager, the available wireless networks are displayed and I can see the relevent open networks, named as expected and shown without the lock icon. I click on the relevent entry, watch a spinner for 30 seconds or so and then it drops off and I have no connection. This happens for "all" open connections.If I look at my defined Wireless Network Connections now, I can see, eg, "Auto Internet@Sea, Last used: never". Editing that connection:

Ubuntu Networking :: AR9285 - Unable To Connect To WPA-Enterprise Networks

Aug 25, 2010

I have a Toshiba NB300 netbook that has an Atheros AR9285 wireless chipset and is running Ubuntu 10.04 Lucid Lynx. At my University there is a FreeRadius authenticated wireless network (called "UCC") that I would like to connect to. Using NetworkManager I have created an automatic profile called "Auto UCC" that contains my user details for the connection. When attempting to connect to the network, the NetworkManager icon spins for a couple of minutes and then presents me with the authentication dialog. If I re-enter my details (and disable the CA cert prompt), it repeats the process seemingly infinitely (spin-spin-spin, auth box) Attached is a copy of the syslog from first attempting to connect to stopping the connection attempts. The wireless card's 'lspci' line is
