1.You can certainly manually configure the power levels on some or all APs, but I wouldn't necessarily recommend this. You can do this through a WCS template for lightweight APs (go to the radio pages - then select Power Assignment then Custom and your desired power level) and push this template to the desired APs
With one customer who had open guest wireless access, we used AP Groups to disable the guest WLANs from the APs that are near the perimeter of the building to prevent people from pulling up in the parking lots for free WiFi.
Another option, which most of my customers use for guest access, is to use web authentication, usually in conjunction with customized web login pages with the client's graphics/logo and a usage agreement. This login page typically requires a password which the staff can give out, and which can be changed as often as desired (weekly, monthly, etc.).
2. just try that but really want a way to list every client.. not just one. I know the wlan they need to be on so i am using the command "show wlan x" and then will check the number on the wlan agains the list of clients we have.
3.WiFi is always promoted using 'theoretical' speeds and by this standard 802.11ac is capable of 1300 megabits per second (Mbps) which is the equivalent of 162.5 megabytes per second (MBps). This is 3x faster than the typical 450Mbps speed attributed to 802.11n
4.Optimised roaming works by sending clients a deauth if they fall below a set of pre-defined thresholds, there are four globally configurable variables that influence the logic behind whether or not to send a client a deauth:
Enable / Disable Optimised Roaming per-band
Reporting Interval (seconds)
Data Rate Threshold (mbps)
RSSI Threshold (set via CHDM)
5.here is no magic to making multiple-AP (roaming) 802.11 networks work. Wireless clients just assume that all APs with the same SSID are configured similarly and are all just different points of access to the same underlying wired network. A client will scan all channels looking for APs publishing the SSID it wants, and will pick whichever one suits its needs best (usually that means whichever one shows the highest signal strength).
Once on the network, clients stay with the same AP as long as it is meeting the client's needs (i.e. as long as its signal strength is above a "good enough" threshold). If the client later thinks it could be better off with another AP on that network, it will do periodic scans of all channels looking for other APs publishing that SSID. If a scan turns up a candidate AP that is enough better than the AP it is currently on, it will automatically roam to the other AP, usually without so much as a missed frame.
6.Yes its supports supported in Model AIR-LAP1262N-A-K9.
