Has anyone else run across this or found a "good" workaround?
I was trying to setup the guest wifi... simple enough give it an SSID and a password. But when enabled and saved... I could see the SSID and connect to it... I get assigned an IP but it doesn't ask for a password and thus you don't get internet access. Normally after connecting to the open connection you get a webpage asking for a password. I can connect the the 2.4G and 5G wifi connection on the same device and modem and they have internet access as they require a password.
Even stranger... disable all wifi... then enable each one at a time save each time and the SSID of the Guest Wifi get appended to and garbled.
Called into Tech support and they have been very helpful... but the only solution is to factory reset the modem... after you reconfig and get the guest wifi working if you change the SSID it will break again. ARGH.
I have a Hitron CGN3 modem. Recently I set up a guest network but even though I set up a password, it never asks for the password but allows any device to connect. Also, when you try to use the guest network, it says there is no internet access. So it essentially useless.
I have tried resetting the guest access, changing its' password, deleting it and redoing it. Nothing seems to make any difference, the result is always the same.
This is an ongoing problem that seems to have been ongoing forever. I don't have any recommendations for you other than to buy your own router and kick the modem into Bridge mode so that the router (far more capable) will run your networks. Sorry 😞
