Ubuntu Networking :: Enable Wireless Bridge - No Corresponding Option
Mar 24, 2010
I want to create the following network:
I have a Belkin 54g ADSL Router/Modem connected to ADSL
I connect my laptop (Ubuntu 8.04) wirelessly to this router
I have a Netgear DGN2000 Router/Modem with NO connection to ADSL
I connect my desktop to the Netgear using a wired connection
I want to bridge the two routers and use the internet on the desktop
The Belkin 54g Router setup has options for Wireless Bridge.. I have selected "Enable Wireless Bridging"; as far as I can tell there is no corresponding option in the Netgear DGN2000's settings to act as a wireless bridge. I have changed the ESSID, Security, and Channel all to the same settings and when I turn on the Netgear router the signal strength of the network dramatically increases. I am unsure whether this is the "Bridge" connected... or if the Netgear's signal is just drowning out the Belkin's signal. In any case I cannot use the internet when connected to the network with the Netgear turned on. What do I do?
Or is there some way I can share internet like this:
wireless wired
ADSL--->Belkin54g----------->Laptop-------------->Desktop

I am using Ubuntu Lucid Lynx (10.04)I have a wireless card in my PC that I only use very occasionally so I uncheck the Enable Wireless option on the network tool icon to stop the system attempting to connect to my wireless network. That works fine for that session, but the system does not seem to remember this setting and attempts to connect the wireless each time I log in! Is this a feature or a bug? and does anyone know a way of defaulting the wireless option to off

My wireless broadband connection was working fine until this morning. I am running UNR 9.04 on an acer aspire one. For some reason i have no option to enable wireless and i don't know what i have done. When i right click all that shows up is "enable networking" but there is no optiont to "enable wireless" anymore. I tried flicking the switch on my netbook to see if that had caused the problem but after doing it and rebooting its still the same.

I'm running 11.04 on a Compaq presario CQ56. The network dropdown menu doesn't even show "Enable wireless" as an option, which makes me think that the wireless card's driver and/or firmware isn't installed. The network card is a Ralink, but I can't figure out which model/chipset
Here is the relevant output for lspci -vnnk:
02:00.0 Network controller [0280]: Ralink corp. Device [1814:5390]
Subsystem: Hewlett-Packard Company Device [103c:1636]

I am new to linux world, recently installed ubuntu desktop 10.10 on old laptop (fujitsu-siemens amilo). When installed, I noticed that the
1. Enable wireless is grayed out
2. Wireless is disabled
Recently acquired a d-link dwl-g122 ver. C1 USB wireless, didn't want to fiddle with original. I am totally new to linux, this is my first installation.
Tried the gksudo gedit /etc/network/interfaces added these lines: auto wlan1
iface wlan1... IT CHANGES to device not managed, tried /etc/NetworkManager/nm-system-settings.conf:
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
Changing it to true the d link is again disabled?
3. When d link is plugged, ubuntu boots but stuck after login screen?
On Vista, home network I use wpa2 psk protection, essid not broadcasting, hidden.

I am trying to connect networks connected via locked down wireless routers. Here is the setup:
Internet <-> eth0 - server - eth1 providing DHCP <-> hub <-> wired clients & to WiFi router with NAT & DHCP <-> WiFi clients.
I want the wired clients and the WiFi clients to be able to talk to each other directly, but the locked down WiFi router (meraki) is in the way. the wired clients get their IP address from the server, the wireless clients get theirs from the meraki WiFi router. I can't reconfigure the WiFi router to bridged mode without paying meraki a sizeable annual license fee. What options are out there to get through the WiFi router? I came across OpenVPN and ethernet bridging, but broke networking on the server when trying to configure the br0 interface. I followed these instructions: [URL]

I have spent the last 24 hours trying to work a wireless bridge (a D-Link DAP-1522) into my network configuration. It would connect to our gateway here at home (some 2WIRE piece of garbage AT&T hands out, but I digress), and two computers (an Ubuntu Desktop and an Ubuntu Server) would connect via the bridge.
The bridge SEEMS to connect to the router, and indeed, the Ubuntu Desktop PC is able to access the internet. The server, however, is not, and neither computer can communicate with the other (ping, SSH, etc.) furthermore, the router recognizes the presence of these two computers on some level, but does not seem to know their IP addresses (I assume this is related to the computers' inability to communicate).
Before I get too far into this, here are a few links/items for the sake of clarity. The first is a shoddy diagram of my (proposed) network topology, for all of you out there who, like myself, understand things visually:[url]
This is the output from running "ifconfig eth0" on the Ubuntu Desktop PC, which sits behind the bridge. The PC is connected, and can ping hosts across the Internet, but can only ping the router locally (that is, it can't ping any other device in the house, on either side of the bridge):
Code:
The router uses wireless encryption, not MAC addresses, to restrict access/traffic, and all wireless devices (including the bridge) have been provided with the proper credentials. There shouldn't be any devices being denied access on account of their MAC address. In fact, the router's control panel lists the PC and the Server among the recognized devices (even lists their MAC addresses), but provides no IP address and always considers the two computers to be "offline." And yet, I am writing this very post from the Ubuntu PC. Sigh.
I am very comfortable with computers, and reasonably comfortable with Ubuntu/Linux and the Linux command line -- I've been using the operating system for just over a year now -- but networking issues have always been perched right on the edge of my understanding. In short, it's likely this issue has more to do with me than it does with the hardware itself (although the more forums I browse, the more I start to doubt this bridge...).

I have a wireless network that is upstairs, i cannot run a cable down here, however i've got 3 boxes that i want to run as servers..
1. Desktop running 10.10 (the one with the wireless card)
2. Server running 9.10 (no wireless card.. is currently connected through a wireless B gaming bridge)
3. An old P4 that I will be putting 9.10 on and running as a server.
Take the Desktop that has the working wireless card as my normal desktop and also running as a passthrough for the switch to go to the other two while still allowing all of the port forwarding to the other two to be handled by the router upstairs so basically what I want to do is this
= wireless connection
- wired connection
[Internet]--[wireless router]==[Desktop]--[switch]--[server1 + server2]
Everything i've come across so far has been for going from a wired router to turn a box into a wireless AP unfortunately i need the reverse.. a wireless bridge. if someone can point me in the right direction (or i'm not against hand holding if it's available.

I first want to say that I am very new to Ubuntu so please forgive any ignorance I have successfully given internet access to my xbox by connecting it via crossover cable to my ubuntu 10.04 laptop and given the eth0 settings "share with other computers" My issue is that the ip address being given to the xbox is 10.42.43.10
How can I change this ip address given, or use a static ip address (ie 192.168.x.x) because using this ip address keeps my xbox from accessing windows shares on WORKGROUP on my 192.168.x.x network.

I am trying to configure an external wireless bridge for a few systems to replace a very long, duct taped cable.
I have it set up and it is connecting, at least I can see the pfsense router on the other side and ping any machine in the network.
Here's the issue, I cannot get dhcp to work across the link. I set a static address (dns servers and all) but when I try to ping google i get "Network is Unreachable"

I have a Windows 7 machine which is having issues with a Linksys Rangeplus wireless card, specifically kernel dumps every couple of hours. I have an old (really old) tower sitting in my room which I would like to turn into a wireless bridge so that I could connect the windows box to the internet without dealing with the blue screens. I plan on using Knoppix as I have it available already, but if it would be easier with another distro I can always download it. If this doesn't work I'm going to have to buy an old WRT54G offline and convert that with DD-WRT...

Using Ubuntu Server 9.10 x64 and a tomato router to act as a wireless bridge to connect to another router. The reason I ask is because I do have the router set on WDS mode on the tomato firmware. I think I have it configured to the best of my ability, but when the interface is up, the signal doesn't get pushed out (no received packets) and it gives something at the bottom of an ifconfig eth0 "Interrupt:28".

I'm trying to share my ethernet via my wireless card. It doesn't work. Here is some info:
lspci
04:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
lsmod
b43, mac80211, cfg80211, ssb
I've tried everything listed in these forums but every time I run
sudo iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
I tried the STA drivers and get the same thing except the kernel module loaded is wl instead of b43. Is it even possible to set this card to master mode? I can't find jack on the net.
uname -r
2.6.31-19-generic

I am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.
Wireless router <=========> Laptop <-----> Switch <-----> PS3
---- wired
==== wireless
Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.

how do you manually reassign a wireless bridge in xubuntu 10.04.. Or basically configure it without having to do so through the installation process.. Hopefully there are commands for it.

[PC]--(wire)--[Router1]--(wire)--[Laptop]==(wireless)==[Router2]::[Internet]
My setup is above, I hope it comes out OK on this forum, and someone can understand what its supposed to be! My problem is I am not sure how to get [PC] to be able to see [Internet]. From [Laptop] I can get both networks to work, and have tried using brctl to bridge them, but as soon as I do "ifconfig br0 up" neither network... works anymore (cant ping either router).

Have a question regarding the implementation of TCP keep alives.
If I enable the option of keep-alives on a TCP socket, is there any way that my application can get the response to the keep-alive back from the kernel. Basically, I have a 'select' blocking on a socket on which I have enabled keep-alives. I need to know if select would unblock if a response to a keep-alive sent by the kernel is received on the socket.

My current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.

I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.

I want to connect my modem straight to my fedora 13 box, using it as a firewall, and I want to use my wireless card to set up an ad-hoc to give internet to the windows computers in my house. My router has been messing up and I am trying to create a quick fix until I can solve the problem.
My eth0 has internet connectivity but when I use the brctl command to try to create a bridge it doesn't let me add my wireless card, wlan0, and also I lose internet while my eth0 is in a bridge. I am fairly new to Linux.

I have a BCM4312 wireless card, using the B43 drivers. It works perfectly fine, except when I bought a new Buffalo Router. I set up the wireless security to be WPA2, but when I use my laptop to connect, the only options are WEP 40/128 key, WEP 128 bit passphrase, LEAP and Dynamic. No WPA of any kind. When I go to edit the wireless settings, I can change the security to WPA2 but when I try to connect again, the wireless manager simply creates another wireless profile with the exact same name with the security WEP. What do I do about this stubborn wireless manager?

I own an hp dv9000 laptop, it comes with a Broadcom STA Wireless card... I currently have my laptop connected to the internet through a wired connection, but there is no option at all for wireless.I've already installed the Additional Drivers to install the Broadcom STA Wireless Drivers, and after I reset, there was no difference, no option to choose wireless instead.

I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."

I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.
I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.
Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.
As my only network options are wireless, this has become a substantial inconvenience.
----
EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working.
-----
EDIT 2:
found this thread:"Wireless disabled by hardware switch" bug? - Natty
seems to be a similar issue. I'll be following how that one develops, too.

I am a day old in ubuntu-world, and I am having internet issues. Yesterday, after i had installed ubuntu alongside windows 7. To begin with it did not detect wireless (not networks but wireless itself), so i figured it was something to do with the adapter and came to these forums where many things were suggested. none worked. So I restarted the system for good measure and lo and behold it detected wireless networks and connected to the internet almost immediately.
Now, after a day, when i have logged in to ubuntu again, there is no wireless detected. The same problem. When I right click on the network icon in the notification area i see that Enable Networking is checked but "Enable Wireless" is darkened. There is no way to check it.
Can anybody please advise as to what to do next. I am using ubuntu 10.04 LTS (Lucid Lynx I believe).My system config is i7, 512MB ram.
