Zyxel ax7501-b0 guest wifi problem

Chris_V

Hi,

I have this Router Model from Yallo.
It works almost all ok, but I'm struggling to use the home guest network on 2.4 GHz for some older devices (set on the "More AP/Guest" wireless option).
For some integration I need to use it to add devices using my phone (Iphone 12 pro). but when using this phone model on the created guest 2.4G wifi I cannot have the internet connection. but if I use the older Iphone 7 it works.. but I need it also with the 12 pro. unfortunately I cannot find any wifi settings on the phone to make it work.

as for the router guest wifi settings "More AP Edit" I set security the WPA2-PSK with password and in "Wireless Network Settings" I tried with and without "Guest WLAN" option (which is very confusing to have it a second option with again "external" and "home guest").
in Other Wireless settings set the 802.11 mode to b/g/n (the older device cannot work with b/g/n/a).
how said most of these settings works (internet connection) anyway with the Iphone 7 but none with the 12.
tried multiple time also to restart the modem but not success.

can someone explain me the problem and limitations of these different settings and  maybe a solution?

tnx

@Chris_V the router is provided by the ISP or you bought it from a store?

IMVHO (which could be completely wrong) you should ask your ISP, which might (or might not) not allow the configuration of all the details of this device/CPE.

Hello @Chris_V

Does your iPhone 12 see the WiFi network id (SSID) of the router at all?

Looking at https://support.apple.com/en-gb/guide/deployment/dep268652e6c/web it seems that iPhones later that iPhone 11 support the 5GHz WiFi band.

Apple give setup instructions at https://support.apple.com/en-us/HT204051 for WiFi on iPhones.
    - and troubleshooting instructions at https://support.apple.com/en-gb/HT204051#:~:text=Reset%20your%20network%20settings&text=If%20you're%20using%20iOS%20or%20iPadOS%2014%20or%20earlier,that%20you've%20used%20before.

So if your iPhone 12 does not see the SSID on the 2.4GHz band, can it see the SSID if you enable 5GHz WiFi on your router?

Kind regards,
      Tony

mMontana, yet didn't asked to ISP because wanted first understand if I'm doing something wrong in the settings. 

tonygibbs16 tnx for the links, will read it better, but the Iphone 12 sees the 2.4 GHz guest network SSID and connects to it, just soon later comes the "no internet connections" warning under it. this when with same wifi is used with internet connection by the iphone 7. already tried to remove it and add it again or restarting also the 12 but not working yet. 
and the other two regular wifi (2.4 and 5GHz) are successfully used with the Iphone 12, just the guest isn't.
for this I'm asking here

Ok @Chris_V You're welcome.

Maybe enabling 5GHz Guest WiFi will be your solution...

Kind regards,

tonygibbs16, tried quick yesterday but it didn't change. also with the 5GHz Guest Wifi the Iphone 12 can only connect but hasn't internet connection.
