HTC Magic :: Wifi Compatability With Routers

I have my new Magic and it works awesomely at the office, my wife's office, my inlaw's router, coffee shop routers.no problem.I take it home, where my 2 laptops, Wii, Palm and Zune all connect and work no problem.So all parts of the magic equation of me getting WiFi at home (thus saving my data plan from racking up huge bills) are a go, except it's not.I have a DLink 614+, and it'll see it, try to connect then say 'unsuccessful'. I've tried rebooting both items, changing the security options on the router etc... but to no avail. HTC Support says it could be something with THAT specific router, but they have exhausted their support binder.Short of swapping out the router with my inlaws, or buying a new one ('cuz then I'd have to change 2 laptops, a Wifi, Palm and a Zune), anybody have any suggestions to make this router work with my Magic?
