Network mapping goofiness
Four computers, two (1&2) wired and two (3&4) wireless all connect to the same router.
1&2 are on the same homegroup - the others can't join. Previously 3&4 were on the same Homegroup and the others couldn't join.
1&2 can't map each other on the Network map.
First snip is from Comp1 and the second is from Comp2
