Securing linksys routers

I have a Linksys wireless router BEFW11SF . it's performing well and I put
basic security measures on it (WEP, changed the password to my router, turn
of beaconing, etc). It accesses the internet fine. Is there any way,
however, to prevent laptops on the wireless network to see other laptops on
teh wireless network (ie, prevent file sharing between laptops or other
srevices). Is there a function on linksys routers to ONLY provider internet
access and nothing else.

I don't need anything specific. just what the function name is and I can
google it further from there.

This may not be what you are looking for, but (assuming you are using
workgroups, not domains) if you put each computer in a separate workgroup
(in other words, gave each one a separate workgroup name), they would still
be able to access the Internet, but I don't believe they would have the
ability to share files.

mea culpa - I misread the orig. post.

Putting computers in different workgroups will not prevent access.
If you are running XP Pro, you can limit access to any computer(s)
If you are running XP home, there is basically no security among computers.

You can stop the machines from pinging each other.

You can stop one machine from accessing another machine on the LAN by
port, protocol, IP, or subnet with a SecPol rule both inbound and
outbound, along with doing the same for the WAN.

It's a piece of cake.

No, there's nothing on the router (or access point) to block traffic.

If you want to prevent Windows computers from seeing each other, you can
disable NetBIOS broadcasts. See URL for info on registry setting.

http://support.microsoft.com/default...NoWebContent=1

Set the value to 2 for peer-to-peer. That will prevent your computer
from sending out broadcasts on the network to tell others about it's
name and IP address, it'll prevent your computer from sending out
broadcasts to find other computers on the network.

You can also disable the server service on your computers, that'll take
care of any file sharing...

With mine I just don't load ICS (internet connection sharing) and they will
not see
each other but be able to surf the internet. Tha's what I do and it works
with all
my machines and it doesn't matter what OS i'm running. If I don't want a
computer
to be seen on the network, that's what I do. Simple as that.

There are ways, such as Duane's suggestion, to control access to/from
a PC that is under your control. But there is no mechanism built into
the Linksys BEFW11S4 AFAIK that will allow a PC to access the WAN but
not the LAN.
