Wifi Won't Stay On All the Time
Newly purchased, 2.1 non-rooted.
So I have my Captivate connected to my home wifi, but after 30min or so, while I'm not using it, it switches back to 3G data transfer. Now this isn't really that bad since it switches back to wifi literally 3 seconds after I unlock it, but I'm still worried that it could be syncing my apps and updating while on 3G data transfer (I have a 200MB/month plan, so I try to use wifi when I can).
Anyone know a fix for this that DOES NOT involve flashing to 2.2 (I know there's a button for exactly this thing, but I really don't want to root my phone. Rooted my LG Vu awhile back and it became a real hassle to maintain)? I have an app called Widgetsiod that can disable 3G data transfer, but it only works if you turn it off while 3G data transfer is on (if it goes into wifi mode and then comes back out of it, 3G will still be on).
tl;dr: Phone loses wifi after 30min of non-use.
