Jun 5, 2011

I have ubuntu 11.04 installed. I have a D-link USB Wireless Adapter. Ubuntu detected it and it worked fine. I have a Beetel 450TC1 Router which broadcasts my internet connection. Ubuntu recognizes it, and keeps on trying to connect.It asks me for Authentication again and again.( Don't tell me to check the password again, it does work on everything else )And its not the router problem also, as I tried broadcasting through a laptop I have, Ubuntu again detected but couldn't connect and kept asking me for Authentication

Ubuntu Networking :: Wirelessly Connecting Desktop With A Linksys Wireless Range Expander?

Sep 30, 2010

After spending several months coming up with ideas (and ultimately failing), I have found the easiest and simplest way to connect your Ubuntu desktop (or laptop w/o a wireless adapter/card) to the Internet using only a Linksys Wireless Range Expander and an Ethernet cord.

YOU WILL NEED:
Linksys Wireless Range Expander (WRE54G)
Ethernet cable

Linksys wireless router (that is providing your home/office with wireless Internet) The WRE54G can be purchased online through various websites, including eBay. They run anywhere between $10 and $40, but it's going to be cheaper than a USB Wireless Adapter (and no software needs to be installed, making it universal for most Linux distros).

Ubuntu Networking :: Connecting To 2 Different Networks At The Same Time?

Apr 10, 2011

I have 2 network cards in my computer, and I would like to connect them to 2 different networks. Both connections work fine when I use them so that the other one is unplugged, but as soon as I connect the second plug (doesn't matter which one is first) they both stop working.I've been googling and reading dozens of pages about how to set this up, but I still can't figure it out.

One connection gets its addresses from DHCP and that connection is used for pretty much everything. The other connection has a static IP, and is used to access just one other computer, which is in the same subnet as that static IP.I'm using Ubuntu and I've been using the NetworkManager Applet to manage my connections. If I've understood my googling correctly, NetworkManager Applet can't be used alone for this kind of setup, is that correct? (Even though it has that "Routes..." button and "Use this connection only for resources on its network" which I've tried for the connection with the static IP, but they don't seem to help.)

So my questions are:

1. So I really can't use NetworkManager Applet for this?

2. What software / tools should I use instead? (My googling brought up such wildly different solutions, and I don't know which ones are outdated, if any.)

3. Should I get rid of NetworkManager Applet completely?

I'm familiar with routing in theory, totally clueless about the networking tools in Linux, but happy to read manuals and happy to learn to use the command line versions if anyone can point me to the right direction.

Ubuntu Networking :: Connecting To Two Networks At The Same Time (11.04)?

May 28, 2011

I would like to my laptop to connect to two networks at the same time.The first network is wireless through which I access the Internet.The other network is a wired router to which my laptop and another computer are connected. would like to connect to the two networks at the same time so I can access the Internet, and talk to the other computer on the wired lan.My problem right now that I can only connect to one network at a time. Even the act of plugging in the cable for the wired network causes the wireless to cease functioning.Could somebody give specific steps. I am on Ubuntu 11.04.

Ubuntu Networking :: 3945ABG Not Connecting To Secure Networks?

Dec 28, 2010

I'm having another slight issue. On a clean install of Ubuntu Studio (10.10), I have installed network manager (manually, using .deb packages, one at a time, including all the extra ones it required) and I can only connect to non-secured networks. If I try to connect to our home network (which has WEP security), it sits thinking about it for a while (with the wireless light flashing, indicating it is doing something), but after a while, it asks for the WEP password again. it works fine if I turn the security off

Networking :: Ubuntu Gateway Server For Connecting Different Networks?

Mar 26, 2009

I have setup an ubuntu gateway server by using four NIC cards.

eth0 :210.212.235.107 is connected to the internet
eth1 :192.168.1.222 is connected to the local network
eth2 :192.168.2.222 is connected to another network

Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.

Fedora Networking :: Connecting To Non-broadcasting Networks Via CLI?

Aug 10, 2009

using a text interface for my computing but I have run into an issue. Does anyone know of a CLI networking tool that will allow me to connect to a non-broadcasting network? I have tried cnetworkmanager and attempted wpa_cli. The first does not seem to support it and I have not played too terribly much with the second. I have discovered that when I boot my comps into KDE and tell NetworkManager to connect to the network cnetworkmanager can find it then, but that does me no good for what I want, which is to boot my computers straight to runlevel 3 and get connected. If it means anything I am running F11 on a Dell Inspiron 1521 Laptop with a Broadcom wireless card (awfully annoying to set up, but it is working fine) as well as F11 on a desktop of my own designing with a Netgear wireless adapter.

P.S. I realize that broadcasting the network would be the trivial solution but alas I am not the admin on the router and he is out of town.

Networking :: Connecting Two Debian Machines Together With Crossover On Different Networks?

Jun 24, 2011

Here is the setup I have. Two debain (squeeze machines) A1(eth0,192.168.33.1, netmask 255.255.255.0) and B1(eth0,192.168.43.1, netmask 255.255.255.0). They both have 3 nics'. So I am trying to connect to each other with a crossover cable and I have added the routes manually. eg: on machine A1 route added was

route add -net 192.168.43.0 netmask 255.255.255.0 gw 192.168.33.2 eth1

and on machine B1

route add -net 192.168.33.0 netmask 255.255.255.0 gw 192.168.43.2 eth1

For project purposes they both have to be on different networks, evn thouhg they are in same room.

Ubuntu Networking :: No Longer See Any Networks Under "Wireless Networks"?

Jan 7, 2010

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.

This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

Ubuntu Networking :: Broadcom Wireless No Longer Recognizes Wireless Networks?

Jan 11, 2010

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.

Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fianc饠after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.

I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:

Ubuntu Networking :: Pavilion Dv6 Wireless - Can't Find Local Wireless Networks

Jun 11, 2011

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.

Ubuntu Networking :: No Wireless Networks Found After A While

Sep 5, 2010

I'm running Ubuntu 10.04 64bit on a Thinkpad T61, and I keep running into some issues with the wireless networks. For a while, the connection works fine (sometimes several hours, sometimes 15 minutes or so--there doesn't appear to be an event associated with it). Eventually, though, the connection disappears; first, though the widgets say I'm connected, nothing will go through, and soon after, it realizes I'm not connected and, moreover, it can't find a single wireless network, despite the fact that it was just fine a couple of minutes beforehand (and other devices still have access to the WLAN, so I know that the router hasn't crapped out). I've tried using wicd, but the same thing happens.

Ubuntu Networking :: Wireless Only Works On Certain Networks

Oct 11, 2010

I have a pretty beat-up laptop, on which the inbuilt wireless doesn't work, and so I now have an ASUS WL-167g, which is acting up!It almost always connects to the required networks without an issue, but then once I'm connected it's REALLY slow on some of them! For example, while I'm at school, it works flawlessly! And at a couple of friends' houses, it works too! however, at home, and at a couple of other places, despite the fact that it connects, its so slow, that google takes like 5 mins to load and searching for anything on google leads it to time out!! This happens whether I'm right next to the router (full signal strength) or 2 floors up (at like 3 bars strength)!

It's getting pretty frustrating to have to swap my lan cable between my desktop and laptop constantly, and also to not be able to use my laptop away from my desk!Does anyone know what might be going on??Also, while i have you guys here! I have another problem -- with the inbuilt card.. Initially, it wouldn't work at all.. but more recently, it has started to function (it connects and works on my home network fine) the only problem is that about 10 mins after I turn the wireless switch on on my laptop, it hangs! (EVERYTIME) (if it's relevant, my laptop is a SONY VAIO VGN-S46GP). Again, any input would be appreciated!!

Ubuntu Networking :: Wireless Networks Not Showing Up?

Oct 17, 2010

I have ubuntu 10.10, and at my house I primarily used wired, and it works fine, and under windows earlier today I was able to locate networks, so my wireless card is working. I'm currently at my girlfriends house, and trying to connect to her wireless internet. When I try to connect, I can't find any networks. I've made sure her network has sharing and discovery enabled, however in my wirelss manager it comes up as blank. There's the option to add wireless manually, but do I really need to go through the trouble of finding the routers mac address and all that, it should just show up?I could switch back to windows to see if I can connect, but I'm almost positive it's just the linux wireless manager..

Ubuntu Networking :: Wireless Networks Only Sometimes Showing Up?

Nov 6, 2010

I arrived in the Central African Republic only to find that my wireless (on an HP Mini 5102) wasn't working -- it didn't detect any wireless networks. So I wiped off Windows and installed Ubuntu 10.10, Luckily, it did! (Partly.) At first, I still didn't get any wireless networks. I messed around with all the various things you have to do to get Broadcom wireless drivers working. Finally, following a forum suggestion, I installed Wicd -- and this did the trick. Not knowing any better, I kept Network Manager alongside Wicd, but Wicd is what works much better. (Is there a reason to un-install Network Manager?)

However, when I try to connect wirelessly to the network at this country's one cafe with wifi (which usually works really well, by CAR standards), the network doesn't appear. At the office, when I open Wicd, it includes a box with the message "<connection name>: obtaining IP address", and bit by bit it connects. But when I open Wicd at the cafe, this doesn't happen -- it just gives me a list of random signals from nearby offices (all secured and low-signal), none of which I can connect to. Any ideas how I could get the cafe network to show up?I'm at the office now, and so it's working. However, in order to get it working I had to restart three times -- Wicd only seems to work about half or 33% of the time. Sometimes I get the message: "Connection failed: unable to get IP address" and sometimes I get the message "No wireless networks detected." Then I try again and eventually it works. So far.

Ubuntu Networking :: Not Detecting Any Wireless Networks?

Feb 27, 2011

First time ever switching from windows. Mainly doing this cause I though it would be fun to learn a new OS and see how it is.From watching a few videos it looked like all I have to do is click on the wifi logo at the top of the screen and I would get my router and a bunch of others (does this on windows) but when I click on it I dont get anything. I think it might be that im running this on a laptop. My wifi card is: Standard Dell Wireless 1501 802.11 g/nIts a new dell inspiron 5000 laptop i customized a little with more ram and a new video card.

Im guessing I will need to provide more info but as I said at the start Im new to this and not sure how or what info I would need to provide. Please just tell me how I can get any data you need and il get right on it. (I used Wubi to install this, went off without a hitch)
