Group Key Renewal
Greetings. I'm new to this site and I have purchased my first TP-Link router. My question is more out of curiosity than anything else. I was going through the router configuration settings. When I came upon the setting for "Group Key Renewal" I was a little surprised to see the default setting was 0 (zero). Meaning no renewal. Pretty much everything I've read about this setting, the default has been 3600 seconds or one hour.
Given the difficulty of cracking a long and complex password, I felt that an hourly group key renewal was redundant. Does the software engineers at TP-Link think the same way or am I completely wrong about what the function of a group key is. The default value is 0 so the engineers don't think its important to renew the key as a timed event. Am I right?
Cheers.
