Until today I had one wireless network in my building. Now I have two wireless networks in my building. The problem is that my iPad 2 with iOS 5 keeping searching and switching between the two. Many times I try to go to a web page and get an error message saying the server cannot be found because the iPad is between networks. Is is possible to make the iPad forget about one network? I fdon't want it to always connect to one as I often take the iPad to different spots and need the auto scan for new networks. I just want it to never search or hook up to a network I wanat to exclude.
