Question about W60 AP security

Hi,

Happy W60 AP user here. I have a question about the security measures, however.

An AES encryption key is generated from the link password configured. Is this key static or does it include some periodic rekeying
mechanism?

Re: Why is nv2 so much slower than 802.11?

For many years I was routinely using nv2 in my layer 2 (bridge/station-bridge) point-to-point links. I assumed that given its proprietary nature, it would offer enhanced thruput, and it allowed me to avoid exposing multiple SSIDs in public that were useless to end-users. That's not the point of NV2...

As far as I know, (correct me if I am wrong) the decision to choose a MCS relies mainly on the S/N ratio. The problem is, in non optimal situations maybe there is a good S/N ratio but the actual CCQ is low because, for example, multipath reflections are causing retransmissions. In that case you may ...
