Problem with Linksys WRT32X 5GHz radio

I had a problem whereby I could not get my android device to connect to the 5GHz wifi on my Linksys WRT32X router. Using a wifi analyser on my phone, there was no transmission from channel 65 which it was set up to. I changed the channel to 50 and the link was then successful. I have read other reports regarding certain channels on WRT32X (5GHz) being inoperable. It uses the Marvell chipset, Does anyone have any more information on this.
