I found this forum in my quest for finding the answer to a question about my WPA Security for my wireless lan.
Basically, I saw that alot of you guys know a great deal about securing wireless connections, and I figured it was worth a try to ask you guys.
All I want to know is: When setting up my WPA security, I have a couple of options. One of them is setting the Shared Key (which is obviously the password duuuhhhh) then there is another option to specify the Group Key Renewal (also known as the Re-Key Interval).
The default setting for the Group Key Renewal is 3600 seconds. The only thing is, I DONT KNOW WHAT THE HELL THIS OPTION DOES?!?!!?
I was literally talking to 4 of the the Live Chat support people at LinkSys.com and asked them about this. They are so clueless.. if you guys want to have some fun just go to the linksys live chat and ask them some simple questions and see how dumb they are. (where do they find these people??)
Anyways, I am hoping one of you guys can explain this group key renewal thing to me. What are the advantages/disadvantages of setting the interval higher or lower? And more importantly, what EXACTLY does this damn thing do???
