I am running RB493G with R52N-M and routerOS 5.22.
I am experiencing disconnection issue, see the log below.
I’ve tried to change many things on the wireless interface and security profile, but no success.
Win 7 and Linux are okay, but Vista and XP have problems no matter how far or close the AP is. Vista and XP work okay with other APs I tried - Linksys and TPLink with same wireless settings, so I am sure they have the most recent drivers and its config is fine.
It looks like a kind of Mikrotik incompatibility.
Here are my currrent settings:
