Right, that's bad.

Try this:

allow-hotplug eth0
iface eth0 inet static

allow-hotplug wlan0
iface wlan0 inet static

auto br0
iface br0 inet static
    address 172.28.45.58
    netmask 255.255.255.192
    broadcast 172.28.45.63
    gateway 172.28.45.32
    dns-nameservers 172.28.45.32 208.67.222.222 8.8.4.4
    bridge_ports eth0 wlan0
    bridge_maxwait 1


Note that now both the eth0 and wlan0 interfaces will have the same
172.28.45.58 address

But for right now, ignore that: just test connectivity and speed on this
netbook while the bridge is in effect.

If you can't get a good approximation of your internet
connection speed from this, there's more to track down.
