New firmware does seem to solve the issue
Someone posted a link to the new Belkin firmware update in another thread discussing this problem. I tried to go ahead and post it here for anyone still having problems with the ipad loosing connection on the Belkin N+ router, but I guess I haven't made enough posts to be able to supply the link. Anyway since applying the new firmware my ipad has quit loosing its connection.
I did have to download the update from Belkins website and manually apply it since clicking "check firmware" on the router page did not show that the update was available.
