No working leases ... inquiring minds want to know

Right ... about WiFi networking...

somewhere along the line I must have missed a tutorial. What does "no working leases in persistent database" mean to me besides -- "It doan make, boss?"

I've come up with this message several times elsewhere and after getting online here with Haysus and the new WiFi yesterday as a test, today it seems to be sticking an electronic tongue out at me when I try to connect from the basement.
