How to wirelessly connect to a SMB from Android.

I’m looking for a way to connect to my home-server running Ubuntu 10.04 with Samba, and my lappy running Ubuntu 12.04 wirelessly to my Android running ICS. I’ve looked at many file browsers like Astro & EX-Manager, but they can’t seem to find the servers?

I have to be able to connect wirelessly and with an unrooted phone.
