Issues with roaming wireless clients

Greetings,
In my home network, I have a TD-W8970B, operating as an ADSL router and WiFi access point, and another access point connected to the W8970B using one of its wired LAN ports, to improve the WiFi coverage at my home.
I have observed an issue when wireless clients roam away from the W8970B to the another access point. They associate properly and smoothly with the other access point but they are unable to communicate with the internet or the rest of the network for a couple of minutes. Only after one or two minutes pass after the clients have associated with the other access point, they are able to communicate in the network and with the internet again.
My suspicion is that if the clients have not explicitly de-authenticated and de-associated from the W8790B before they roamed over to the other access point and associate with it, the W8790B considers them to be still associated to itself. As a result, it keeps the MAC addresses of these clients in its switching table, tied to the wireless interface, and does not re-learn them onto the LAN interface even if the frames from these clients are received on it. Consequently, all frames targeted to these stations are sent out the wireless interface, instead of being forwarded via the proper LAN interface.
My question therefore is: Is there a way to decrease the time during which an (unresponsive) wireless client is still considered as being associated, and/or, is there a way to decrease the MAC address aging time in the switching table of the W8970B?
Thank you!
Best regards,
Peter
