Hi,
I have solved this problem with a little different aproach and much less
money. You don't need a wireless accesspoint.
I have 3(xp, xp, linux-mandrake) desktops and 1(linux-debian) server
at home and a laptop(w2k/RedHat).
Two of the desktops are connected by wire, one is connected with
wireless, laptop can be connected with wire/wireless depending on which
room I am in.
The debian machine has 3 network devices:
eth0 (eepro100) -to dsl line,
eth1 (tulip) -to 8 port 100Mbps switch,
wlan0 (hostap) -USRobotics Wireless card
The hostap driver is capable of performing all the AP related functions
in software. It works with most PRISM 2/2.5 cards, should work with
orinoco.
eth1 & wlan0 are then bound into a bridge:
/etc/network/interfaces
auto br0
iface br0 inet static
address 192.168.11.1
netmask 255.255.255.0
network 192.168.11.0
broadcast 192.168.11.255
bridge_ports eth1 wlan0
I use NAT on br0 to make internet connection available to all my
internal network.
The server also runs:
dhcpd (DHCP server, all the client machines use DHCP to get their
internal IP address)
DNS server
dhcp-dns to update dns entries whenever a new client connects
smtp & imap server for mail.
By creating a bridge, I was able to keep all my client machines on
the same subnet and saved myself from the routing nightmare.
