I've recently had a visit from a corporate IT representative. He suggests we change the bss-minrate so that the signal distance is less but stronger. Apparently 45Mbps down is not good enough. We have an AP in every room so coverage is great. I understand this is all done via CLI, I can log in but cannot find the option. I have read the bss-minrate vs smart-roam article but it doesn't tell me how to do it.
Could someone advise the basic commands I need to know and also the options I have for changing the signal distance? Also should I be aware of any possible outage when making this change? Can I apply this to a single WLAN-Group for testing only?
Thank you both for your input. I have just three questions.
Is there a command like a "show" command in Cisco that I can see what the current rate is at?
In reference to the NOTE from Kristijan, if I set it to 12, does that mean it will only allow 12Mbps rate and above?
In reference to Monnat's recommendation, is there any way to check what speeds devices are running at so I can make a decision what to set my minrate at? In this particular WLAN every device is exactly the same (wireless GPS transmitters).
you will see something like this...
NAME = your_SSID
Tx. Rate of Management Frame(2.4GHz) = 6.0Mbps Tx. Rate of Management Frame(5GHz) = 6.0Mbps
Beacon Interval = 100ms
SSID = your_SSID
Description = blank
Type = Standard Usage
Authentication = 802.1x-eap
EAP TYPE = PEAP
Encryption = wpa2
Algorithm = auto
FT Roaming = Disabled
802.11k Neighbor report = Disabled
Web Authentication = Disabled
Authentication Server =
Called-Station-Id type = wlan-bssid
Tunnel Mode = Disabled
Background Scanning = Enabled
Max. Clients = 350
Isolation per AP = Enabled
Isolation across AP = Disabled
if you set minimum rate to whatever (6, 12, 24...) that will be the lowest rate at which the AP will communicate with clients.
The answer to your final question is > just check what 802.11 standards those devices support. Check in their options or just google it. Or check on the wi-fi.org under certificates database for particular product and you'll see a specification and what that device supports
