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.
Sorry I took so long, but I decided to upgrade my Zyxel switch to the latest firmware before trying out your suggested solution with VLAN 1977.
However, it took me some time because the default IP address was 192.168.1.1 and it proved difficult to reach the WEB configurator. Happily, I found a post on REDDIT which helped me set the IP address to 192.168.1.2. Then I successfully upgraded the firmware. And it seems to work fine.
However, I can find nothing in the configuration option in the WEB configurator that look anything like your suggested changes. Pity.
Maybe I should buy the Swisscom switch, but it does seem to be a rather old tp-link device.
I'm sorry to read that your Zyxel switch is not supporting tagged vlan setup.
Note that the Swisscom TP-Link switch is more than enough unless you need multi gig capability (with the 2.5Gb/s port of the Internet-Box 3 for example). It performs well and you can set up a lot of things if needed. Obviously it comes pre-configured for Swisscom services like TV over the switch, guest WLAN over a WLAN-Box, Bonding for the Internet-Booster, etc. It's certainly not the most recent gigabit device on the market but you would likely not get much better performance with a more recent gigabit switch.... last but not least it's not very expensive 🙂
