Disable a specific wireless interface in Ubuntu?

http://serverfault.com – I have a Ubuntu 11.04 running with two wireless interfaces -- one onboard (seen as wlan0) and one external card via USB, seen as wlan1. I would like to only use the USB card, completely ignoring the onboard one. Currently when I enable wireless both interfaces come up. How do I make Ubuntu ignore wlan0? (HowTos)

I am running Ubuntu Server 12.04. I have a wireless USB card. When I begin the boot process I see:

Waiting for network configuration

It turns out that the network never comes up. But once I get to the command line, if I type: ifup wlan0, then I have network access.

Hi, total noob here and im having some trouble using virtualbox on ubuntu 10.04 host with winxp guest.

basically i have 2 wireless cards, 1. broadcom bcm14313 and 2.

So I have a linux box with two wireless interfaces, one is a station and the other an AP.

wlan0 (station) - Connected to the internet connection

wlan1 (AP) - Other clients connect to it.

I would like for clients connected to wlan1 to be able to access the internet on wlan0.

Let R1 and R2 be two (wireless) routers. Both R1 and R2 have one wired interface eth0 and one wireless interface wlan0. On each router, both interfaces are bridged on br0.

I have a WiFi card on my Ubuntu 12.10 desktop box, the name of that card is wlan0, when I try to manually set up wlan0 to use DHCP from /etc/network/interfaces as showing below:

auto wlan0 iface wlan0 inet dhcp

Ubuntu can't boot.

However if using network-manager applet to setup dhcp for wlan0, wlan0 works well. I wonder what is wrong with my current setting for wlan0 card.

Currently I need to manually setup my wireless network each time I boot up. I wish to automate it so that the settings are correct on boot up.

I have a usb dongle for wireless works fine can connect to any rooter.

dnsmasq-base is installed dnsmasq is not installed

when i create a new wireless connexion UbuntuAdhoc connexion try to connect during several mins and disconnect

phoenix@phoenix:~$ sudo cat /etc/network/interfaces auto lo iface lo inet loopback

auto wlan0 iface wlan0 inet static wireless-mode ad-hoc wireless-channel 4 wirel

When I issue the command

iwconfig wlan0 essid NAME

it sometimes takes a really long time to actually be able to view any webpages through a browser. I don't know why that is.

[ubuntu] Wireless suddenly dead 2 years 27 weeks ago

I've had the odd issue with my wireless PCI card over the past few months but a reboot seemed to cure it. Yesterday it seemed to die altogether. NO mention of wlan0 in any lists and no connection. Tried moving the card to another PCI slot which I knew worked as it had been housing a USB extension card but still no worky worky.
