No Network Connection?

[JediJames]

Recently I decided to upgrade to Gutsy, which gave me a nifty kernal upgrade taking me to 2.6.22-8-generic, which had a known bug with my wireless network adapter's chipset, so I still used 2.6.20-16-generic while I waited for the next upgrade. I was so happy when I saw that I would be upgrading to 2.6.22-9-generic, and happier when my wireless adapter worked. Sadly things aren't that cool, now I am unable to connect to my network via wired or wireless, does anyone known of this problem?

I'll post my 'interface' file contents for reference, but I can't post the result of 'ifconfig' or 'iwconfig' as I have booted into 2.6.20-16-generic again and the results of this version and 2.6.22-9-generic are different for some reason.

/etc/network/interfaces

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0


iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp

auto eth2
iface eth2 inet dhcp

auto ath0
iface ath0 inet dhcp



auto wlan0
iface wlan0 inet dhcp
wireless-essid default

auto eth0



iface rausb0 inet dhcp
wireless-essid default



auto rausb0

FYI 'wlan0' is the interface that 2.6.22-9-generic uses and 'rausb0' is the interface 2.6.20-16-generic uses. Any help will be appreciated, as I am still pretty new to Linux.

Re: No Network Connection?

I decided that the results of iwconfig would be useless because this problem persists over both wired and wireless, but after comparing the results of ifconfig from both kernels I noticed a couple differences, so perhaps the problem lies there.

ifconfig

If anything doesn't look right to you let me know. Just FYI, 'wmaster0' which is an unspecified device interface, does not appear in kernel version 2.6.20-16-generic. Also if there seems to be a bug somewhere let me know so I can report it to the development staff.
