[erlang-questions] erlang nodes over a wifi network

Hi all,

I'm trying to connect several  erlang nodes over a wifi network. The
same application works  perfectly over ethernet but when I go
wireless, approximately every 5  minutes I get a noconnection error in
some of the nodes (nodes  reconnect by themselves after a period of
time that goes from 5 secs to  1min).

I'm setting the following kernel parameters  in the sys.config:

[{kernel, [{sync_nodes_mandatory, []}, {sync_nodes_optional,
['']}, {sync_nodes_timeout, 5000}]},

Nodes communicate with each other  issuing rpc calls.

Are there any recommendations you could  point out in order to connect
several erlang nodes over a medium quality  wifi network? (quality is
in average 50%). The network quality is  not perfect but seems good
enough for other applications (ssh, http...).

Any help would be greatly appreciated.  Thanks in advance.

Quique
