I have a dlink DIR-636L router and I have a very strange issue with it.
My local network only works when my desktop is running. When it's off, all my other computers have the "No internet access" warning. When I turn on my desktop, suddenly the network is fine. The issue happens both with wifi and cable.
The only thing I could think of is that the router doesn't have dhcp enabled and that my desktop is handling addressing on the network but the router's control pannel says dhcp is enabled.
Does anyone have a clue of what could be causing such a weird thing?
