Ubuntu: How to get wireless lan and 10/100 running simultaneously?

2

I am running Ubuntu 10.10 on a Dell Inspiron 6400. I am able to get 10/100 Ethernet card and Wireless Lan working independently.

  • Ethernet -> eth0
  • Wireless Lan -> eth1.

If I restart/reboot my eth0 turns starts up fine. If I then manually start my wireless connection (eth1), eth0 disappears.

There seems to be issues with wireless drivers: I don't have the cleanest solution but I run this script:

rmmod b43 
rmmod b44 
rmmod ssb
rmmod wl
cp /home/stew/Desktop/brcmDriver/wl.ko  /lib/modules/2.6.35-22-generic/kernel/net/wireless/
modprobe lib80211
insmod wl.

I then do:

wpa-supplicant (with essid and passphrase)
sudo ifup eth1

Is there any way I can have them running simultaneously? From reading around I believe it's possible but not quite sure what I'm doing wrong.

Or any good references that will help me understand from a more fundamental level.

Did you try with network manager? Does network manager show you both interfaces? – Peltier – 2011-10-14T12:03:59.713

Firstly apologies I didn't realize this had been moved to superuser (Thanks Gareth for doing that!). I uninstalled network manager as I read it can interfere with NIC bonding which is what my real goal is. But when it was running both interfaces worked (not sure if simultaneously or not.) Any suggestions? – user929821 – 2011-10-19T19:10:08.570

I would very suggest doing the following:

in:

/etc/network/interfaces

define the entry for your wired connection like so:

auto eth0
iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254

or

auto eth0
iface eth0 inet dhcp

You can do the same with Wireless connection as well but I think the Network Manager might work out better for you.

One question I do have to ask is:

Why 2 connections active at the same time?

Hi Karlson, I only just saw this! Thank you. I was experimenting with torrent and thought it might be able to take advantage of two different networks, also to provide redundancy and potentially incrementally increase bandwidth. – user929821 – 2012-06-22T20:00:55.667

@user929821 The potential bandwidth that you can use only depends on your outbound connection and it's utilization – Karlson – 2012-06-22T20:15:58.513

Two different networks...4G and cable. Although my example show wlan and lan....the eventual target was cable and cell. @Karlson not sure if the at id is working. – user929821 – 2012-06-22T20:16:49.047

@user929821 at id? – Karlson – 2012-06-22T20:45:07.030
