Evo malo da se.pozalim da imam slican problem kao s tplinkom. Nakon puno spajanja/klijenata AP ne dozvoljava vise nijedno spajanje.pa se vise nitko ne moze spojit dok ne istekam ap iz struje. Neznam.jel.to zbog trenutne kolicine klijenata ( u jednom momentu i 80-90 )ili zbog memoriranih klijenata koji trenutno nisu spojeni. Lease time je postavljen na 00:10:00. Postoji li mogucnost da nastimam da svakog klijenta koji se odspoji drzi u memoriji par minuta i da ga skroz izbrise tj. Da ponovo trazi lozinku
To još uvijek nakon svega napisanog na jednom AP-u?
Može bit i Cisco/Meraki, to se ne radi.
80-90 korisnika ide, al' ono, goli minimum, dva AP-a, optimalno 4.
Ovisno o prometu i to bi znalo izdahnut.
Jesi provjerio CPU zauzeće pri tolikom opterećenju?
Jedan qoute sa Cisco support foruma:

Let me answer your question not with a NUMBER of clients, but rather with a "how it works and why you shouldn't over populate your AP".

1. Its not really what the AP can handle. In fact standard 802.11-2007 tells us there can be up to 2,007 AIDs per AP. Although you wouldn't want 2007 clients on a AP for obvious reasons.And in fact I don't know if Cisco or other vendors have a hard limit as to how many can associate to an ap.

2. The issue becomes not in how many connections a AP can handle. Rather how much congestion is within a cell when you have an excessive number of device in a cell (also referred to as channel). Access points are HUBs. Only 1 device can trigger a frame at any givien time. No full duplex

3. CSMA/CA is what makes 802.11 work. There is a phyiscal and virtual carrier sense that is occuring all the time on a wifi nic. The NIC senses the channel energy (noise as well as 802.11 frames) and they sense frame triggers.

4. So if only 1 client can trigger a frame at any given time. As you add more and more devices to a channel less and less medium becomes avaiable.
