You don't ping a subnet mask. However, if you haven't already try pinging the bridges default address of 192.168.1.250, instead of 10.xx.yy.1

Also, just mess with the subnet mask on your computer. Try it at 255.0.0.0 and 255.255.255.0

Also navigate to the routers homepage which should be 10.xx.yy.4 xxyy being your team number of course. Make sure all security is off. In fact I think you should be able to DMZ everything too, which should solve your problem if it is security related.

DMZ would be a dangerous thing to do if connected to the internet, but for connecting to a robot, you should be fine, haha.
