I have enabled the Guest Network feature on my Internet-2 Box. I also have a WLAN Box (extender). The main WLAN network performs correctly from (in range of) either box. But the Guest network only works via the Internet-2 box.
When only in range of the extension box it says it has a self assigned IP address and no Internet access. Would be nice if the Guest network worked everywhere the main network worked. Is this a feature, a bug or a config error.
In case someone else arrives here. It turns out, from Swisscom technical support, that the Guest WiFi network simply does not work on the WLAN box. WLAN box is only 5Gz and Guest Network is only 2.4Gz !!!
Ah, interesting information. I do indeed have a Xytel switch in between the Internet box and the WLAN box. I will look into it when I have some time.
But it still does not excuse the fact that Swisscom tech support did not know that a switch between the two boxes could cause such a problem. I would have thought that would be relatively common configuration.
That is the reason why Swisscom sells recommended Switches by Netgear, which are preconfigured for this kind of setup. Or why they offer config files with the necessary settings to be downloaded and installed onto such Netgear Switches. If you want to use your own equipment you would have to configure the details yourself and honesty VLAN settings are not a very common support case. But yes, a very ver well educated support line can know about this technical depth and problems arising with other hardware than the official recommended or sold one.
