Transfers slow only one way

I have two Series 2's on my network. Right now I have one wired and one wireless (Linksys B on the TiVo). If I transfer from the wired to the wireless it's not bad, almost real time. But when I try to transfer from the wireless to the wired it's pathetically slow. I'm eventually going to wire the other one once it's cool enough to venture into the attic but what can I do in the meantime?
