Welcome to Vodafone Community
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?
Even the older VOX2.5/HHG2500 has WPA2! WPA3 will not really come into its own until all your devices can use it and it's available on the majority of routers.
As for why your device is telling you that you have weak security - purely and simply it's an Apple device, they like to scare their customers in order to get them to spend more money!
"...purely and simply it's an Apple device, they like to scare their customers in order to get them to spend more money!"
Not an Apple fan, I see. However you're wrong. The device is purely stating it can support higher encryption modes over wireless, it's nothing to do with scaring anyone to spend more money.
To the OP: The latest VF router (THG3000) does not support WPA3 with the latest firmware, but it does WPA2. It may do so in later firmware iterations.
