wireless routers
Hello, I have 5 wireless routers that I need to configure on the same network. I need them to roam with each other. I understand that I need to have the same SSID & security enabled on all of them, but they need to have different channels. My routers go from channel 1 to 11. How far apart should I make the channels on each router?
please & thank you

thanks for the post jakob_di.
I'm using the 22mHz channel width. Just so I'm sure on this, I don't want them to overlap? does this mean that every single time a user with a laptop moves from one area to another, he will drop in wifi and then reconnect or will he have continues connection?

he might loose a packet or to, so if he's in a VoIP call or streaming video - they might notice this. But else this shouldn't be any problem
How many users do you expect will be using this?
Have you bought APs?

no access points. This is a basic work wireless that started of with one wireless router and now grew into five. I have a dhcp server which distributes IPs. The wireless routers are just used for wireless. Five of them in total. I'm a bit confused on the channel range. So what would happen if I was to set up my channels as 1,3,5,7 and 11? I understand that these channels do overlap. So if I was to start watching a YouTube video on a tablet and start walking from one end of the building to the other it would drop me off the wifi as the signal is picked up by the next router? Please explain jakob_di.
The only way to have seamless roaming is to use WPA-enterprise or WPA2-enterprise (recommended) security having a RADIUS server checking login credentials with a database such as your domain usernames and passwords, Protected EAP (PEAP) and EAP-MSCHAP v2 authentication with Enable Fast Reconnect checked. 
Then as you approach another AP the client will preauthenticate before disconnecting from the current AP and when the switch takes place they keep the same IP address and you won't notice when it switches from one to another.
Without using that option, when you switch APs it drops the current connection, authenticates with the new AP and gets an IP address from the DHCP server, then resumes the previous connection[s]. That produces a disconnected state for 10 to 20 seconds. Even if you use IP reservations by MAC address with the DHCP server, it still renews the lease. Using static IPs might cut the 'disconnected' time in half, but that would still be noticable if you're in the middle of watching a youtube video. (sounds dangerous walking around watching videos, by the way... haven't you seen the clips of people falling into manholes, et cetera, while walking down the street texting?)
Only channels 1, 6 and 11 should be used on the 2.4GHz band, as mentioned previously.
Here's an example of how to arrange them for full coverage

Thank you for the post darr247.
Is there a forum or a website not u know of that gives instructions on how to setup a simple radius server?

What OS is your server?
ASKER
Microsoft server 2008 (not r2)
Well, then... try these

And you might use the Request Attention link under your original question and ask the admin to add the Windows Server 2008 topic to the question, as well... I no longer have a copy of any of the microsoft server versions from which to give step by step directions.
