Hi Michel

For 802.11b, the simplest thing you can do is to ask your "director" to
select a different frequency channel both client and the router... but I
have feelings that the WLAN setting is so "generic" or by factory default,
e.g. default SSID, no encryption.

Therefore, you may want to ask him to re-config the WLAN equipment in a more
secured way, including encryption (WEP, WAP, LEAP), disable broadcast,
regular change of SSID, use MAC and IP filter.

Regards
Ellis Wong

And addendum to that question, do any wireless routers contain tools so that
you can block all but specific hardware addresses? That is, my home wireless
router would block all but my hardware address, much like hard-wired
networks often require registration of hardware addresses before allowing a
new system to access it. I do believe there are methods of spoofing hardware
addresses but that aside, do wireless routers have capabilities for this
sort of thing that a home user could easily administer to better secure
their home network?

Disclaimer: I'm also a newbie so please forgive any misconceptions or false
assumptions!

Hi,
I have a user who uses a wireless network at home. He just asked me
(it's a director) to find a way to avoid his laptop (Toshiba tecra running
XP Pro) connecting on the neighbor's router instead of his. He has a D-Link
614+, I don't know this model at all so I'm asking you guys if you know a
way to restrict his laptop to only HIS router.

As you can see, I'm not very familiar with Wireless :/

Thanks for any inputs
