View Full Version : [ubuntu] 11.04 getting troubles with wired/wireless setup

May 1st, 2011, 12:17 PM
Hi there,

I am facing a problem with the management of my network card after installing Ubuntu 11.04 32-bit Desktop edition.

There are two Network Cards and one USB adapter which I'd like to drive:

- Ethernet controller Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
- Ethernet controller Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
- Realtek Semiconductor Corp. RTL8187 Wireless Adapter

Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled.
Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw ( to the eth0 device and the network is useless.

Is there a way on how to do automatically?

I am having the same problem with Ubuntu 11.04 32bit desktop
and 2 NIC (wired & wireless):
so to use etho I have to disable wlan0 et viceversa!
Any suggestion?
