I would use the same SSID on all the AP's if you want to allow roaming. If
the AP's are running encryption, then you might have to test if roaming works
properly with your AP's (you didn't specify brand, but I use Cisco AP1242
lightweight AP's here at work, but the principals are the same).
You should stick to the 3 non-overlapping channels (1,6,11). I would not mix
the other channels in (2-5,7-10). If you have problems with interference from
one AP to another, check the AP settings and see if you can drop the power
output to shrink the bubble. If the AP's have external antennas, you can get
attenuators to put in-line between the AP and antenna to accomplish the same
We use attenuators from http://www.tessco.com.

Subject: [m0n0wall] m0n0wall + Captive portal + 20 AP's setup question
First of all excuse me for this off topic post, but I know this list is as
one full of people with lots of knowledge and experience in setting up
So, to me it looked like the best place to fire my question.
Here we go,
We need to provide wireless acces in a residence with approx. 150 rooms.
It's devided over 5 floors and we already provided utp cabling to 4 acces
points per floor. (so a total of 20 acces points)
All acces points are connected to a switch, which is also connected to a
The m0n0wall does dhcp and runs the captive portal.
Now the question.
Should i only use the non-overlapping channels (1-6-11) and use slightly
different ssid's on all AP's?
Or should i use more then those 3 channels? (and also different ssid's)
Or should I use only one channel and the same SSID on all AP's? (m0n0wall is
the gateway for all of them anyway...)
I hope someone can give me some good advice on this.
