bought a 240AC - guest network w/ captive portal

[BroncoBilli]

Booted up this AC240 and added a guest network, with captive network assistant turned on, and captive portal set to "internal", and access type set to "local user account". I went into advanced settings and added a local user. Great. Now, when I connect to that wireless network on Windows 10 (latest), it says the wifi is 'open' and "connects", but the Edge browser says, "The wi-fi hotspot your using may require you to go to its sign-in page", and there is a "connect" button. when I click on it, nothing happens. If I do the same process with my apple iPhone, it takes me to  a login page. If I use Firefox Mozilla, it says "log into network" and below it says "192.0.2.1 uses an invalid security certificate", and "accept the risk and continue?". The place where I want to use this AP is full of anti-techies. Installing a certificate on their device won't be possible. Plus, they're going to want to connect on their TV and stuff. Yikes. Yeah - in fact, how WOULD you connect to wifi that requires a login/password from a TV? Never thought about that until now.

Anyhow, how do I get around the bad-cert issue?

ANSWER: I turned off WebAuth SecureWeb under Management/Access. Wow.

Now: about TV's and connecting to captive portal Wifi. Is this simply not possible?

- using http (turning off Secureweb) looks like your only option on this product but we aware that means the usernames and passwords will be sent over the air in clear text if you're using an open SSID, so anybody can capture those credentials.  Professional products allow you to use a proper public certificate which would avoid those problems (but you'd need to update the cert annually).

- to mitigate that you could at least use WPA2 with pre-shared key on the SSID - and then maybe you don't need the login?

- many game consoles, TVs, google/amazon products now support captive portal for login to public wifi - so really just depends on the product.

Yeah, well... the TV is Vizio, and came from Costco, and does not allow captive portal. Neither does the Roku box I added to the TV. If neither of these very popular items allows captive portal, then I'm assuming that's about 90% of the market out of there for people who stream TV's. I guess this is Microsoft Edge's problem w/ captive portal, not the Cisco box's... Since Firefox allows me to 'continue" using the wonky cert, and Edge simply farts out, I'm guessing it's Edge's issue...
