Hold tight, this is a strange one...
I have a board with two network adapters, one lan and one wifi, each one properly configured and has its own ip address on the same network.
Whenever they're both connected, they both work fine, but whenever I disconnect the lan cale, the wifi connection drops too.
googling about it points the blame on some router setting, so here's my router model: tp link td-w8901n
thanks
