Help! Home Network's SICK!

HELP!

We had our cable modem connected to a NetGear
router. One of the outputs of the router went to
a hub. All was well.

My daughter came home from college and hooked her
own NetGear router to one of the lines. This additional
one is essentially the same as the other router, except
that it also has a wireless feature. We had three
macs and a PC on the net. My daughter added her
router, to which her PC is hardwired and her mac
(powerbook) runs wirelessly (internal Airport card).
A total now of four macs and two PCs in the house now.

We had a power hit at the house, and I pulled the
power on all the boxes (computers, hubs, routers)
to reset them, as we've done dozens of times whenever
this sort of thing has happened in the past.

Results:

The PC on my daughter's router was using its default
IP address (169..something..169) and linking to my
own powerbook, so when I brought my powerbook back on
line again, the re-init caused my automatic DHCP IP to
always end up being that 169...169 address. So we took
the PC off the net, and I was able to get back on the
internet.

The wireless router has stopped working. My daughter
has attempted several times to reset it and reconfigure
it to accept both her and my powerbook, but no luck.
Wireless refuses to work.

Our shared HP Laserjet has stopped working. It's a mac
version (2100M) connected to the net via an Asante ethernet-
to-serial bridge adapter. I've known about its penchant for
needing to be the last item powered up so it doesn't
get all confused, and I've reset it last several times
to no avail.

Anyone got any idea what's going on? With all the
routers and hubs being dongle (DC) powered, a power
interruption shouldn't have done anything terrible.
All the computers are running fine otherwise. Just
no wireless and no Laserjet. Is there a particular
order I should init the various boxes in, like I
have to do with the Asante bridge?

Any comments/help appreciated!
