WPA2(AES) or WPA3

[PanLondonSI]

Recently my iPhone says that I have ‘Weak Security’ on my Wi-Fi. I’m pretty IT savvy and know my way round routers. I have WPA2 selected but the router does not have any better security available to choose. When I spoke to Vodafone on their chat, they told me WPA2(AES) & WPA3 is already enabled. But clearly it isn’t. My question is (in the chat, the operator kept avoiding the question), do Vodafone provide routers that enable us to use WPA2(AES) or WPA3?

Great article over at ArsT explaining the WPA/WPA2/WPA3 protocols

Unfortunately there is a vulnerability in the existing WPA2 protocol and it is not been patched on some devices out there
Search for: "KRAck".

Issues such as KRAck are one of the reasons that some ISP such as Vodafone lock down their hardware so tightly. We still regularly get the stories posted from several years back about unpatched routers, rest assured that the Vodafone routers are reported as patched!

Even if they weren't the problem persists that you need both router and clients with that hardware WPA3 ability built in before you can use it.
