Arduino Wi-Fi shield switch between client and server

Is it possible to switch between client and server using an Arduino Wi-Fi shield?

That is, switch between server mode and client mode on the fly on a

WiFiServer server(80);
WiFiClient client;

This works for incomming clients, but if I try to use the client to connect to some site with client.connect(serverName, 80) ... client.stop(), the Arduino will receive the page content of that page, then it will hang, it won't accept any new clients (it won't respond when I use the browser to connect to it.

I tried using a separate WiFiclient for the connect part, but with the same result:

client = server.available();... After using connect, this part won't work anymore.

So, what I'm doing wrong?

It seems that my problem was caused by some bugs in the firmware.

The "old" firmware that was on the shield when I bought it had some problems dealing with client and server running both on the Arduino.

They fixed it and a bunch of other issues since then, so it's best to upgrade the shield's firmware to it's latest revision.

Here is a guide on how to do upgrade the firmware on the Arduino WiFiShield.

And here is a list with the issues they fixed.
