Thanks for your reply.
DHCP Lease duration we have set to 1 day for our student devices, we have 3 vlans that all have there own IP/SSID assigned with /22 subnet should provide 1022 devices per ssid ( ample for our requirements) staff and students are split with departmental laptops on there own ssid also.
i have had to do it this way for our filtering requirements etc.
we are running windows server no other services are running so its own dedicated virtual machine database size is only 600mb we dont use the captive portal or anything like that it is purely for staff or students both locked down filtering etc server is 4gb ram and dual 2.8ghz processors - i was under the impression that the controller was only used for initial setup and if you were using the guest captive portal?
AP seem to have an even split across all so around 25 i have also set the balance workstations per radio to 30 all set to use HT20 not 40
i read somewhere that you can use the secondary port on the AP Pro to give it 2gb uplink (this seems questionable) as i cant find any details anywhere on there site, do you know about this? i always assumed it was for attaching another device like the documentation states.
i think it may be to do with co-channel interference. can you recommend any tools we can use to test?
thanks for your help
