I currently have a net gear Router. Before upgrading iPad to iOS 5 everything ran seamlessly. Now that I have upgraded the OS, my wifi signal drops frequently. I don't know what to do. I have reset all settings, full factory settings restore, reset router and I'm lost. I took my iPad to McDonald's today and it ran flawlessly...no problems. So I obviously have something going on with the router....but I just don't know what to do.
