Wifi issues with iphone not responding

Question

Phone: iPhone 4s.
This issue started approximately two weeks ago. My phone initially started with the Wifi connection greyed out, I followed the appropriate steps to resolve this issue, and was successful. Now I can turn the wifi connection on without problems, but my iPhone will freeze (delay), then return me to my homescreen. Occasionally I do automatically connect to my known wifi, but then will disconnect and return to 3G. If I make an attempt to go to settings to manually reconnect, the phone again freezes. The phone seems to freeze after I click settings, then when pressing Wi-Fi, the bar turns dark bold, but freezes and doesn't open. I then have to click my home button, return to the main menu. Also if I open an app during the seldom opportunity my phone is connected to wifi, the phone will disconnect, return to 3G and freeze. I have rebooted my routers, forgot networks, reset network settings. I have thought about resetting the entire phone, but my phone will not stay connected to wifi long enough for me to back up my data to iCloud. I am thinking of stopping into my local verizon store, but I think they will redirect me to an apple store; which is 35 miles away. Of course the problem with me not connecting to Wi-Fi is my increased use of data. Now I am over 75% for my monthly usage with 2 weeks remaining, and do not see justification in possibly having to pay the overage fee. Many times when my phone freezes due to these wifi issues, or will not respond, I have to do the manual power/home reset. In conclusion, I need to figure out how to maintain my connection to Wi-fi, and stop my phone from not responding when I open my wifi settings. Thanks in advance!

My Iphone 4S is doing the same thing..  All of a sudden the WIFI button is gray and not working.  I chatted online with a Rep.  He had me call *228 and hit option 1, then call again and hit option 2.  All of a sudden the WIFI button was black.  But it could not find any network.  I shut it off and restarted it and now button gray again.  I called that number again and still gray.  I read somewhere else that a lot of people have a problem with the WIFI button.  They say it basically just stops working.  This was a replacement phone because the volume stopped working on my original phone.  I assume they gave me a refurbished one because it didn't seem new.   I'm due an upgrade in 3 months.   I'm disabled and just hate driving to the store again.  I wish there was an easier way.
