When using Ruckus APs in a High Density enviroment, some clients refuse to roam when they should and others roam excessively.
What (if anything) would be better than the following config for avoiding roaming issues in a high AP density environment?
..assuming a non-encrypted guest network...
Create 2 WLANs:
description "public 5Ghz SSID"
description "public 2.4Ghz SSID"
Create 2 WLAN groups:
Then assign the WLAN groups to the appropriate radio of each AP.
1) Turn off band-balancing a.k.a. band-steering to prevent an AP from accidentially pushing a 2.4Ghz client to a further-away 2.4Ghz radio instead of the intended local 5Ghz radio.
2) set ofdm-only to prevent old "B-only" clients from dropping the AP to "B-only" mode.
3) set bss-minrate to prevent clients from going to lower speeds. (and encourage them to roam to a nearer AP on their own)
4) set smart-roam (not recommended by Ruckus?) to kick clients off an AP when the AP sees a very poor signal from the client. (and "force" a client to roam)
5) Use different SSIDs for the 2.4Ghz radios vs the 5Ghz radios.
Even though I've already turned off band-steering and load-balancing, the clients may still decide to jump back+forth between 2.4Ghz and 5Ghz radios.
Using a different SSID for each band makes a client less likely to decide to roam between bands.
This still leaves the possibility for 2.4Ghz clients to decide to excessively jump between 2.4Ghz radios.
If you need a way to prevent that kind of roaming, you could take the additional step of assigning a unique SSID/WLAN to each radio on each AP.
If your environment doesn't suffer from excessive roaming, you can add a single "public" SSID that exists on all radios.
End users would then be able to choose the SSID that works best for them.
If anyone has a better solution, please let me know.
I syslog to a linux machine to store logs that I can check for roaming and other problems.
Max O'Driscoll posted good information about syslogging to an external windows server:
smartroam factors + equivalent db/signal-percentages:
kick-off a client when the dB value is below:
1 5db/ 2%?
These are the dB/signal-percentages you see under the monitor tab when looking at clients.
