wifi keeps disconnecting

[bandtank]

My Droid has randomly been disconnecting from my home wifi. If I restart the phone it will connect again, but within a few hours it will disconnect and go back to using 3G. My 3G connect is solid but this phone has tons of other issues syncing with gmail and constantly disconnecting from google talk, but I'll save those for another topic. For now I'd just like to see if there is a reason my wifi connection keeps dropping. I've uninstalled tons of apps, but they were all installed before this started happening so I doubt those had anything to do with this.
