I have a relatively simple need: to set up a WLAN with maybe one Windows 7 PC, and several iPads. The PC will be running a Socket Server, and the iPads will be communicating with the server via TCP and UDP. There will be no internet access.
I have experienced lots of problems, for instance using an Apple Airport Extreme, with the iPads dropping their connection and not reconnecting.
What is the most reliable solution to accomplish this? Cost is not really an issue (within reason).
