I am currently running RC1 7 Ultimate. I have been dealing with a crazy amount of internet connection drops between hardwired and wireless. I have tried the following:

WMP-300N card (constant disconnects)
WMP-600N card (constant disconnects)
WGA-600N Dual-Band Wireless-N Gaming Adapter (constant disconnects or won't connect)
DAP-1522 Bridge (Constant Disconnects)

All of those I have proven to work in a stable Vista 32 home install and are all stable in that environment. I have also proven that is not my service provider or Apple Router that I use as a main router from my 2 laptops, 2 iphones and other desktop.

The only solution I have found to correct this issue of the constant internet dropouts is:

Bridge the wireless connection of my laptop > D-Link DIR-655 and then LAN off the router. This seems completely obscene, but look at everything I have tried. Is there a certain protocol that just refreshes your connection if it drops under X bandwidth or goes over it? I do a ton of online gaming and really would love to keep a 64bit system as I run 8gb of ram. Thanks for any help in advance.
