not allowed routers where i work, id like to know if it'a possible to have hidden ssid (so no one sees my ad hoc)

share the hard wire internet connection, set my wifi computer wireless ip then i go my network places, "set up a home of small office..." dont know wtf this does, but after i can connect and use the hardwired connection...

works great untill the iphone goes into lock mode, i guess wifi is shut down, connection is stopped. when i unlock it it comes back, but i cant access the internet connection unless i redo the "set up a small office..."

anybody has a clue what "set up a ..." does or how i could have it reconnect without having to go thru this every time it locks up?
