I'm sorry if I cannot help you with the actual problem, but if you need
to change your default gateway setting temporarily, you can do so
quickly and non-destructively from the commandline. First check your
routing table in a console:
$ sudo route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 2 0 0
wlan0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0
wlan0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0
wlan0
In this case my default gateway is 192.168.1.1. Yours might differ, keep
a note of what it is. Delete it with:
$ sudo route del default gw
Add a new temporary one (this does not survive a reboot, so it's a safe
thing to do):
$ sudo route add default gw your.ip.address.here
Viola! You can do your tests now. You can change your default gateway
back by doing the above and substituting with your old gateway, or
simply reboot.
