In condo complex and have MY wireless router/cable box. I want to ONLY
connect to MINE.

If mine should hiccup etc at startup, there are many nearby non-protected
wireless routers from the 40 other tenants in complex. Right now if I " view
available wireless networks" there are 22. I would like to " ignore all
others" and ONLY use mine. If mine has an issue, I understand that I won't
be able to connect. - How to do so using Windows XP ?

Your wireless device(s) must support MAC filtering. You need to
enable such filtering on your access point, and set it to accept the MAC
address(es) of the remote machines you want to allow.

You will also need to enable MAC filtering on your client end, and
tell it to use only the MAC address of your specific access point.

If your devices do not support MAC filters, you will need to use
other devices that do.

Happy tweaking.

Which will do nothing to help his original question. That and MAC filtering
is false security. All it takes for someone else to overcome it is to reset
their client card to use one of your MAC addresses, which are broadcast in
the clear and easily detected. That and if/when your card dies you'll have
to remember there's no way to get back into the access point because the new
card's MAC isn't known. More trouble than it's worth.

Not sure that's going to work either.

You can configure windows to either connect or not connect to unsecured
networks. Don't recall right off where that checkbox is present. But that
will keep your machine from trying to connect to anything else besides the
network you've got setup already.

Some wifi card have more configurable software than others. Intel's
software offers quite a few features for use with their cards. It may be
worth considering a switch to a different wireless card to gain better
client-side features.

You don't need MAC filtering. The Windows XP supplicant ("WZC") has an option
to not automatically connect to any network not on your "preferred list". If
you turn the option on and put only your network on your preferred list,
you'll be OK. You will, of course, want to turn on encryption (WPA-PSK will be
fine for your purpose) so that someone else can't replicate your SSID and
cause you to accidentally connect. That will also keep unwanted users off of
your network and do it much more effectively than MAC filtering would.

One caution: Many supplicants, including WZC, have the annoying habit of
automatically adding a network to your preferred list if you connect to it
manually. So if for some reason you do decide to connect to someone else's
network, don't forget to delete it from your preferred list afterwards.

Bob,
I went here and they mentioned it, no specifics though:
http://support.microsoft.com/kb/815485/en-us

I AM running XP SP2 on new laptop (HP w/AMD x2), WPA set and I have all
updates, so I have this on my pc already , right ? ( as in I don't need to
download it).
But - is this something I invoke ? Just that checkbox ? If not, how to
utilize it ?
When I look at wireless networks, what's available/ settings etc - here's
what I see:
"Wireless Network Connection - Properties shows available and Preferred
list. If I select ADVANCED it shows
"Networks to access" - I chose "access point (infrastructure) only" and have
"automatically connect to non-preferred etworks" unchecked. That my only
option.

I have the wireless areas I DO use arranged so home is first.
So I thought
if my wireless router not on = no connection, but still if mine is off,
these others have no security and my Pc found them and connected.

I DId just update firmware on the linksys router = maybe now I need another
XP update ?
or should that have done it ?

thanks
bobb

Yeah, but see below.

It won't connect to one of them if
- It's not on your preferred list, AND
- You've turned off "Automatically connect to non-preferred networks", AND
- You haven't connected to that network before (or you have but you've
subsequently removed it from your preferred list).

Other supplicants behave differently. The Intel supplicant, for example, lets
you tell it not to connect automatically to some network on its permanent
machine-specific list, then goes ahead and automatically connects to it
anyway. I haven't seen that behavior in the Microsoft supplicant.

: I DId just update firmware on the linksys router = maybe now I need another
: XP update ?
: or should that have done it ?

SP2 doesn't include the upgrade to the supplicant to allow it to handle WPA2
(which is slightly better than WPA). If you want that, you have to go find an
additional patch on the Microsoft Web site.

That won't help.

>tell it to use only the MAC address of your specific access point.


Many (most?) clients won't do that.

No, you will need to (1) use a unique SSID for your network and (2)
configure your client _not_ to connect to open networks. If you further
use WPA with a strong passphrase, there is no real chance of connecting
to the wrong network.
