There's lots of discussions on this topic on the Apple Community, particularly with iOS 6+. Here's Apple's help on this issue - http://support.apple.com/kb/TS1559 If this doesn't solve the issue I suggest you search the Apple Support Community forums as you'll get many, many answers.
Hope it works for you.

Having just a replacement iphone 4s less than two weeks ago (black screen) this has now happened. I have to told by Apple that I need to change my iphone again.
NOT GOOD ENOUGH APPLE
There is no point in having good customer service if your product quality is deteriorating. I have 3 iphones and 2 ipads in my household and will seriously think about any future purchases.

The product quality isn't dropping. You've just been unfortunate enough to have the issue occur to you, even though the incidence rate of this issue is extremely low.
Are your other two iPhones or two iPads experiencing this issue?

I use non-Apple products as well. But thanks for being insulting!
The rate of incidence of any iPhone suffering from any wi-fi issue is less than 0.5%.
This is not a major issue.
Show me any research that indicates this is a 'common' issue.
