iPad2 prefers weak open Wi-Fi networks over a strong, secure, known networks
My office is in a building with a restaurant about 50 feet, and several brick walls away. The restaurant has a free/open Wi-Fi network. I frequently have lunch there and read the news on my iPad.
My office Wi-Fi router is about 10 feet from my desk. The office network uses WPA2.
Almost every time I grab my iPad in the office it connects to the very weak, not really working from here, unsecure restaurant network. It doesn't matter if I was last using the secure office Wi-Fi. "Forgetting" the open network doesn't help since it's immediately found again.
I have the same problem at home where my own home (preferred) network is secure, but several neighbors have open/unsecure networks.
Why does the iPad always prefer open/unsecure networks that I never want to use, over my own secure networks? Is there a way to stop that behavior?
It seems like there should be a switch called "ALWAYS USE KNOWN, LOCKED WI-FI NETWORKS IF AVAILABLE" or something like that.
The iPad status bar only shows the signal strength, not the network name, so every time I turn on the iPad I have to go into the Settings page to make sure I'm on the proper network.
This also seems like a real security problem since any apps that are running when I turn on the iPad probably try to connect to the Internet as soon as the open/unsecure network is available.
