  • My guess is that existing WAPs should get a firmware update to include support for WPA3.

    So now in addition to seeing "WEP" and "WPA2" as options, we would see "WPA3" as well when choosing which encryption standard to use.

    Isn't the main difference in WPA3 a more secure "handshake" process to mitigate the latest KRACK vulnerability? I think this could be implemented with a firmware update, but I could be wrong.

  • This could be, in many cases implemented with firmware update, but I think that it will be only on enterprise models and not consumer/prosumer models. We can expect increase in processing complexity that a lot of devices will not be able to handle, also, manufacturers will have to apply for WPA3 certification, and this is not feasible from business standpoint. Another thing to consider would be that companies can release updates only to buyers with an active maintenance contract, or could limit themselfs to only newer devices, etc.

    If you're building a new enviroment, can you wait whole year to get WPA3 certified devices? You can ask you manufacturer if they will give an assurance, but I would not expect them to do that for another half year.

    If you have enviroment and you only need few new devices, can you wait and change all of them with certified later?

  • WPA2 has gone through different iteratations on the same hardware for years. It would be fair to say that older chipset APs could struggle a bit with the CPU cycles it’ll take to decrypt and encrypt data using WPA3.

    It won’t be long before AP vendors announce 802.11ax with WPA3. It’ll be the clients that lag behind. Aerohive already announced 802.11ax enabled radios.
