try with another brand of AP Client and see if it works.

In your RouterOS configuration you can block client->client communication by turning off “default forwarding” for the wireless card.

I beleive it is what Inox says, Your clients wireless cards do you use the same chipset as your wireless AP, If your AP is using atheros, then your Clients should be using the same wirelless card chipsets, such as D-link, and i beleive netgear… But i am not sure at all of what you have for CPE clients… But i have had this problem it the past or similiar, a dissocation of the client, and to fix it they hit repair , get reconnected, and in 15 or less mins they can use the web and get dissocatied… It should show up in your log when they have this problem.. If the dissocation is now show in the log, then it mite be a worm or something similar to what Normis said… Thats my 2 cents.. -Jordan
