at node 1 gw, may notice that it added the new default "default 10.5.0.6
0.0.0.0 UG 2 0 0 wlan0" route but both the client node 2 when node 1 gw are
without internet connection, I do not know why he did not remove the first
route that is not more being achieved. Maybe it's because the wan node 1 gw
this set of static and not in dhcp mode.
