These changes made to my iPad/iPhone and router worked for me. I had loss of signal even if signal indicate a strong radio symbol. This will increase your signal strength and make it more reliable. Just wanted share.

iPad / iPhone:
Go to SETTINGS
Go to BRIGHTNESS (iPhone) or BRIGHTNESS AND WALLPAPER (iPad)
Turn "Auto-Brightness" OFF
Slide the "Brightness" slider all the way to the right. (brightest)

Wifi Router:
In your routers "Advanced Wireless Settings" 
Change "Fragmentation Threshold" from 2346 to 2305
Change "CTS/RTS Threshold" from 2347 to 2304
If you have a setting called "Preamble Mode" make sure it is set to "Long Preamble"

Make sure your wifi is using a 2.4ghz signal and 20mhz bandwidth too.

802.11 B/G/A and now N  operate  in either 2.4 Ghz range or 5 Ghz.  Some will do both like N most are locked in to a single range with 2.4 being the most popular nowadays. 

If getting excessive fragmentation you may have environmental issues and be better served by switching to a 5 Ghz N router.   

Wireless acts like a big hub in as much as its shared media and any device in the airspace can compete with other devices for the bandwidth.  If more than 1 device transmits data you get a collision. 

Do those Apple devices support the N band? 

On the other hand if this works,  then good on ya!!

Wireless is as much art as science ;)

I couldn't connect at 5gHz. After much research I found Apple products and most products don't support 5. 5 has a hard time going through walls ect too. According to Apple support they only recommend 2.4ghz with 20mhz bandwidth. My old router was a N router and that worked fine. This new modem was kicking my butt!

The biggest improvement was changing lighting setting. Apple is aware of this issue which is a power management issue. They are suppose to fix it.
