I used to set my WiFi security using WEP to support legacy WiFi dongles that can't handle WPA (or other new encryption scheme).
Recently, I've dumped those old dongles and got new ones. I am now moving to WPA2.
While setting up WPA2, there is a setting called "Group Key Renewal" that has a default value of 3600 seconds.
Question: Does this mean that all wireless connection to the router will be dropped every 3600 seconds to renew their key?
