Hello all,

I have an rb411ah with r52h, with a 8gbi antenna and 4.13 that i use to server wireless to users in my work network, max 20 users.
i'm using wpa2-personal with psk and aes.

after some time, i get high ping times (100-300ms) with timeouts.
some clients are getting kicked out with extnesive data loss.
other clients are getting kicked out with 'dynamic key exchange timeout'

all works well if i reboot the router (plug the poe cable out and then back in).

what is going on and how do i fix it?

How long it works fine after reboot?

a few days.

some unauthorised user is persistently try to connect.

have u tried mac authentication

nop.
i should see theese auth attempts using wireless logs?


wpa2-enterprise with radius on Active Directory would help?

I think you should give a try to management protection on the security profile.

But all your clients must be Mikrotik.

make an access list n enable mac authentication

i can try mac filtering -- add each mac to an access list, but this can work only for known clients (laptops & print servers).

for temporary wireless clients (guests) should i use an hotspot with limmitted connection time & bandwidth, and no auth?

Have a virtual profile for guests with limited time /bandwidth
