Homemade dual band network

[wrkngclasshero]

I have the wireless N airport base station (not the dual band) and I also have an old airport express (B/G only). Is there any way I can set up my home wireless network so that the express handles all of the B/G traffic and the base stations handles all of the N traffic (thus not slowing down my N stuff with the G stuff).

If this is possible, would somebody be able to provide idiot proof, step by step instructions for me. Thanks a ton!!!

Page 37. Set up your AEX in Bridge Mode and connect it to one of your AEBS's LAN ports. And be sure to set your AEBS to 802.11n only (either 2.4GHz or 5GHz), and give both networks unique SSIDs (ie, NetworkN and NetworkG)
