IOS – What does it mean if I see “security recommendation” next to a wifi network
ioswifi
I recently went to a restaurant and found that their wifi network has "security recommendation" next to its name. I've never seen it before, and wonder if it might be a new thing introduced in iOS 10.
After connecting to an open network, iOS 10 will display a "Security Recommendation" notification beneath the network's name in the WiFi menu settings. When a user opens up the Security Recommendation, they're greeted with a notification that "open networks provide no security and expose all network traffic." There's also a recommendation to configure your router to use AES encryption for the network.
My guess is that the iPhone doesn't consider the connection valid because there's no DHCP service assigning it an IP or perhaps gateway allowing it access to the internet.
Try running a DHCP server on your laptop or enabling network sharing even if the laptop isn't on the net.
If you have checked both the user keychain and the system keychain for old passwords, we're left with obscure guesses.
Two things come immediately to mind (from the obscure side).
Your mac will join any base station with that SSID. I have seen people literally setting up a second router in busy coffee shops - you have to hold the option key and make note of the mac address you have connected to and see it change to catch this.
If your wifi connects to the router wifi, it doesn't mean the dhcp server has any more addresses to lease. You will need the owner to reset or power cycle the router to see if the leases are all out and unexpired. You basicall have a great pipe connecting you to the main, but no water is flowing to you until you get a lease.
