Multiple Access Points and SSID's

Hi all,

I'm in the process of installing a 13 access points throughout a building.

I have assigned a different SSID for each access point.

The problem I have is that when the laptop moves closer to the next access
point, the hand over does not always occur. Sometimes when it does occur,
the second access points attempts to gain an IP address and then stops and
says "no or limited connectivity" in windows. Sometimes the second access
points gets an IP address and says connected but won't actually allow
browsing in IE.

I'm wondering if this could be solved by giving all access points the same
SSID?

Any thoughts would be greatly appreciated.

Same SSID, different channels.

Ever notice that most buildings to not have a 13th floor?

Be sure to locate your 13 access points in a manner where those on
different non-overlapping channels, do not hear or interfere with each
other. You'll need a channel plan to prevent mutual interference. I
strongly suggest you read through this document from Intel on "hot
spot" topology and planning before blundering onward:

Not a good idea.

Yep. That's exactly what will happen if you do it that way. You
should use a single SSID and different channels. Use non-overlapping
channels such as 1, 6, and 11.

Yep. However, be advised that some client radios will stick
tenatiously to one access point before finally deciding to let go and
scan for a better connection. This arrangement has a problem where
one is not being able to select a specific access point or even
determine to which access point one is connected. It's usually not a
problem for most roaming users, but be prepared to deal with it.

I would suggest you install 12 access points and one spare. Leave out
the 13th.

some access points don't roam well, like the two I have,, can roam one way
but not back - in the back roam the radio connects but mapping for the
ip/mac is still aimed at the one it orig roamed to AP so while it says
connected, it is radio connected and is not network connected. .

I say go with 14 AP's 7 is a lucky floor number and floor 14 is twice as
lucky because if you climbed the stairs all the way past 13 without a heart
attack, you're damb lucky.

-->I have 3 AP's in my building, 7th, 3rd and 1st floors and used same SSID
for all of 'em.
Set my ( 802.11b/g ) channels to 1 for 1st floor, 11 for 3rd and 6 for 7th
floor ( roofdeck).

Works well for me. I take a laptop in the elevator and from the basement,
locks on to each AP on the way up to the roof.
With 13 ap's though, you will have to channel space in combination with a
signal meter or netstumbler type program, etc. to get the channel
interference down though.

Hope this helps! :-)
