RE: Wireless ADSL stuff

["Mark Harrison" <Mark.Harrison@xxxxxxx>]

>From Linksys:

"Roaming is the ability of a wireless computer user to communicate
continuously while moving freely throughout an area greater than that
covered by a single access point. In such a system, the users end node
undertakes a search for the best possible access to the system. First, it
evaluates such factors as signal strength and quality. Based on that
information the node next selects the strongest Access Point and registers
its address. Communications between end node and host computer can then be
transmitted up and down the backbone. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search.
Upon finding a new access point, it then reregisters, and the communication
process continues."


Blech!

Thanks to everyone for their help and suggestions (esp. Mark and Mary for
giving up a Saturday afternoon). I've now got the following set up on my
living room floor for testing purposes (good job I'm single)

Alcatel 510 DSL router
Linksys 8 port switch
2 x WAP 11s

All took about an hour to set up out of the box, plus a scary half hour
where I thought a failed firmware update had fried one of the WAPs! Using 3
workstations plus the router with the switch gives far better performance
than peer-peer networking even with encryption turned on.

For those of you using these in corporate settings, is there a minimum
recommended channel spacing between adjacent APs, and do they operate on a
hand-off basis like cellular phones should do, or are they like cellular
phones really work, and you have to loose the signal from the really weak
base station before you can log on to the base station you are less than a
foot away from?

Any resources that can point me in the direction of encryption together
with XP, and is it possible to mix 128 and 64 bit encryption (I'm pretty
sure that one is a no-no)? In particular what is the difference between
open and shared key, and both?

Tim - who's been using wireless for ages, but only peer-peer.
