Unable to identify wireless home network printer to install

Spruce Street

I hope this doesn’t end up as a duplicate up my earlier attempt to ask
question. I timed out just as I sent and it doesn’t seem to have posted.

Two wireless laptops connected wirelessly through a Linksys access point
that is hardwired to a Dell 1700n printer. Previously no problems with
either machine printing.

Dad is a Dell D620 running XP Pro, Network Associates AV, and recently added
Spysweeper.

Mom is a Sony Vaio PCG TR3a running XP Home, Network Associates AV and also
recently added Spysweeper. Also, we recently rebuilt her hard drive. Since
then, Mom cannot print unless Dad is awake. I am unable to install the Dell
1700n on her computer because I can’t find it on the network.

I have run Home Network multiple times, bounced router and machines. Dad
can see all and do all. Mom can see Dad, and his files and the Dell printer
on his machine, but I cannot find the printer from her machine. I can Ping
the IP address of the printer from her machine, but I can’t browse to it or
have the network go to it by entering either the IP address or the port name
(scavenged from properties in Dad’s computer) in the Add Printer wizard.

The other peculiar and annoying element, maybe not relevant, is that when I
run the home network wizard, it sets up a network bridge that ruins my
connectivity to the access point until I delete manually it. This never
happened to me before and I haven’t been able to control that.

Help!
