Wired and Wireless ethernet problem A20 Lime2

[sdrollinger]

Hello,

I have a wired Ethernet connection and a wireless connection.  I'm using the wired Ethernet to communicate to a computer not on the network which collects data and puts it in a local (olimex) MySQL database.  Then we query the information from the MySQL database from the wireless network.

The problem I'm having is if the wired Ethernet connection is made (plugged in) I can't query from MySQL.  Also if I ssh into the device from USB I can't ping anything on the wireless network.  Once the wired Ethernet is disconnected everything works again.

Here is the contents of /etc/network/interfaces
****************
auto lo
iface lo inet loopback

auto eth0

iface eth0 inet static
address 192.168.200.100
netmask 255.255.255.0
hwaddress ether 00:80:A3:99:B4:C6

auto usb0
#iface usb0 inet dhcp
iface usb0 inet static
address 192.168.2.1
netmask 255.255.255.0
#gateway 192.168.2.1

#auto wlan1
iface wlan1 inet dhcp
wpa-ssid YourSSID
wpa-psk YourPass
*****************

The wlan gets assigned an address something like 10.24.64.xxx
Any help would be appreciated.

In the MySQL config file my.cnf
bind-address = 0.0.0.0
I read this should make it listen on all interfaces.

Thank you,

Steve

What is the output from ifconfig and route with and without the ethernet connection ?

Sorry guys, this is not what's happening. When the the eth0 is connected everything is still working fine.  The only problem we are experiencing is querying MySQL from the wlan interface if the eth0 is also connected.  I will post the my.cnf file as well.

Here is the route information

Two strange things :
- your default gateway is currently the IP of the board itself, it should be the IP of your router.
- the MySQL bind-address isn't 0.0.0.0, like you mentioned earlier.
