mdns won't work with new radio

[tuskiomi]

SOLVED. Solution below

My team has been having this problem for the past few weeks now, and I cannot seem to find a solution.
We can control the robot and have code, but there is no support for mDNS.
Normally this wouldn't be an issue, but our Smart Dashboard is not behaving properly because of this. We just re-flashed the router yesterday, and there is no luck. We also cannot connect to 172.22.11.2

SOLUTION: turn off IPV6 adresses
