School wide wireless dropping.
We are experiencing a problem with our wireless network at school. What happens is; a laptop will see the wireless network fine and connect but will randomly drop connection. This could be after 5 minutes or after an hour. The wireless is still showing as full signal but it just won't connect. Then it will just connect by itself again.
This is happening school wide and to any laptop at any time. All channels have been checked and changed where necessary so there are no conflicts. The wireless has been fine for years, nothing has changed and now this all of a sudden. We are really stuck.
If anyone has any ideas that would be great. Thanks.
