[tlug] Local network routing problem

Hello TLUGers, the signal from the wireless router in the basement is
not strong enough to reach the second floor reliably, so I thought I
would put to use one of the spare wireless routers I have to make an
additional access point upstairs. So, I connected it to the ethernet
jack on the second floor and everything is fine -- sort of.

The network of the downstairs router and the wired network is
192.168.1.0. I made the network for the second floor router
192.168.0.0. This works fine, but my son can't access the shared
folder on his windows desktop machine (on the wired 192.168.1.0 net)
from his Macbook (on the wireless 192.168.0.0 net).

So, I thought I'd put them all on the same subnet. I made the upstairs
router the same 192.168.1.0 network, made its IP address 192.168.1.151
(beyond the range of DHCP addresses of the basement router), and had
it assign addresses 192.168.1.152 to 192.168.1.200 by DHCP. For some
reason, I still can't see the Windows shares like this. But worse
still, I can't ssh into my Linux box in the basement (192.168.1.2)
from my laptop on the upstairs wireless network (with IP address
192.168.1.152). It tells me no route to host.

Then I got the bright idea of making the netmask on the two networks
255.255.0.0. But when I did that, I couldn't log into any remote
machine. I kept getting ``No route to host'' errors.

Perhaps someone can explain to me a couple of things:
1) How come when my laptop is on the same subnet, it can't find a
route to my desktop machine in the basement?
2) How do I access Windows shares from the upstairs wireless network?
This is important because the printer is served by samba on my Linux
box downstairs.

Thanks in advance for the enlightenment.
