I have setup two interfaces from my laptop running ubuntu natty 11.04. One interface is wlan0. The other interface is eth0. I have configured wpa_supplicant on wlan0 on subnet 192.168.1.1 I have configured eth0 on subnet 192.168.0.0.

I can always browse to most websites (eg. google.com) all the time, regardless if eth0 is up or not. But when eth0 is up (ifup eth0) then I can't open some websites, like github.com, or leafletjs.com... Chrome says "This webpage is not available"

Here is my... Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.0.0.0 * 255.0.0.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default homestation 0.0.0.0 UG 0 0 0 wlan0

(homestation is the hostname for 192.168.1.1, my router)

And this is my current network configuration (/etc/network/interfaces):

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet static
    address 192.168.0.1
    netmask 255.0.0.0

    auto wlan0
    iface wlan0 inet static
    address 192.168.1.254
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 192.168.1.1

    # WPA configuration
    wpa-driver wext
    wpa-ssid Movistar_15332923
    wpa-ap-scan 1
    wpa-proto WPA
    wpa-pairwise TKIP CCMP
    wpa-group TKIP
    wpa-key-mgmt WPA-PSK
    wpa-psk XXXXXXXXXXXXXXXXXX

Any help will be appreciated!
