You want the APs to be on different radio channels so that you do not experience radio interference. Wireless devices can roam between them so long as they share the same SSID. The channel doesn't matter when it comes to roaming handoffs, the client is switching from one BSSID to another BSSID within the same SSID. But if you use the same channel, you are creating radio interference in the overlap area that will result in a performance drop and in extreme cases might cause a wireless node to get knocked off entirely and have to re-associate.

I totally disagree with this
in the case of WDS and the subject of this thread.
The WDS specs state that the
AP's radio signal between each other must be on the same channel. The only way you can do any different is to have an AP with two radio cards, one for WDS on one channel, and another for associated devices on another channel. I don't think most home users would have the option to do this (nor would they really need to) with the current brands of AP's on the consumer market.
If you aren't using WDS, as it sounds like JimDarcy is not, then you could have different channels for each AP and this would reduce the interference between AP's just like when you are dueling with your neighbor over channels. But, again I have found that my
8320 doesn't do a great job handing off between two different channels.
Anyone else have luck with an 8320 handing off consistently between two AP's with different channels?
Here is a link to some technical info on WDS and how the channels work if you want more info on this: (WARNING, PDF)
