I used to have WiFi issues on my OG Droid. For example I couldn't have Bluetooth and WiFi on at times and in the notification bar I never had any bars for WiFi. My speeds where ok.
This happened on multiple routers I had but like you on a open network everything worked fine.
What I had to do was factory reset my router. For whatever reason factory reseting the thing made it work perfectly.
