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!
So then it does have to loose contact with the first access point
before
it looks for another. It isn’t a massive deal, but I’d hardly
equate that to roaming freely. I see what you mean regarding the hub versus
switch argument. I’m visualizing this as I type. Only the relevant
lights
are flashing. I do seem to remember reading something on the Compaq website
regarding keeping adjacent cells at least two channels apart – not
really
an issue with 14 channels and two access points J

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.
