Ok, I found a temporary fix for this. It's not Ideal because you have to do it for each Wifi Network you connect to. But if you must have the new build, and don't want your wifi dropping in and out, here ya go.
Download Wifi Buddy (free on android market.) I'm sure there are other programs you can use, but this is the one I know.
Download Gtech Net Tools (Again Free on Market).
Enable your wifi like usual.
Go into Gtech, Click IP Config. Click Wifi, and write down all your settings while it's still connected. If it drops out while your doing this, just refresh when it connects again.
Write down your connected/IP, Subnet Mask, Gateway, and DNS Server.
Exit, and open Wifi Buddy.
Click preferances, Wifi Networks, Hit your Menu Button, Click advanced.
Goto Use Static IP, and plug in the info you wrote down from Gtech.
(Netmask = Subnet Mask)
Arrow back once the info is in place, and connect to your Wifi.
It'll Stay stable, and no longer keep dropping, and reobtaining your Wifi.
For any new connections, rinse and repeat.
Cheers
