RC4 wireless bug - the same like RC2?

AP cards: CM9
clients: Realtek 8186 (OvisLink WL5460AP)

Clients randomly lost communication with AP. I need to disable and enable wlan card.
Probably clients switch to sleep mode.

The same problem appears with two RB333 with Atheros (CM9) - WDS mode.

I have too! this problem but with no WDS with ap bridge mode (edimax 7206apg)
with 2.9.X no problem!

please email to support@mikrotik.com when you are experiencing this problem, we could look info this.

I have same problem too.Clients ap with realtek chipset(ovis5460,awap201,CC WA-2204A) are still connected in acces list but dont communicate.I have to remove it from access list after reconnecting start communicate.
