regardless of which preamble-mode I am using (I have tried long/short/both), I can’t connect with Nokia E52, Apple iPad to my R52n. While the network is visible for the client, the equipment won’t connect. Not even try. Turning on debug, wireless simply doesn’t produce ANY record (while the same test with the same AP + regular notebook produces nicely “wireless,debug wlan1: MAC address attempts to associate” etc…). Not even in 2GHz-B, any Proprietary Extensions, no Nstreme.
Any other idea PLEASE?
Specs:
RouterBOARD R52n “AR922X rev.1” on RB433UAH (mipsbe), RouterOS 5.5, 5,6
Notebook WiFi - Intel WiFi Link 5100AGN
Are you using security? If yes, make sure it is AES and not TKIP.
Please contact support@mikrotik.com with the support output file which is made after you tried to connect with ipad to the AP.
Even though I do not want to use TKIP for security reasons, the connectivity will start working after I enable TKIP too (unicast-ciphers=tkip,aes-ccm group-ciphers=tkip,aes-ccm).
Only then will equipment establish aes-ccm connection (as reported by /interface wireless registration-table print detail stat).
I am not quite sure where the bug is, it would be nice nonetheless to fix it.
Later I also found other reference to this problem at forum.
