Do I understand that correctly, it just doesn’t work over WLAN, or do you have the same problem with a LAN connection?

For me, your site works over LAN (Swisscom) and also over 4G (Swisscom).

The server information is also available:

Have you tried entering a different DNS in the router? Personally, I use the Adblock DNS from nextdns.io behind a Cloudflare DNS.

Alternatively, you can also use the following:

1.1.1.1 (Cloudflare), 8.8.8.8 (Google) or 9.9.9.9 (Quad9)

@Fliossapa82 this depends on the router. We have an IB3 at home. The setting can be accessed there at https://internetbox.swisscom.ch/#network/settings/ip-settings.

You then have to scroll to “DNS server”.

To isolate the error, the suggestion from my colleagues with the DNS makes sense, but it still has to work if you don’t mess with the DNS and leave everything on automatic. Hence my questions:

Does the problem also exist if the newly commissioned PC is switched off?

Apart from the website that is not accessible, are all other websites easily accessible from all devices (Swisscom, SRF, Blick,…)?

Does an error message appear when you try to access the page?

Have you already restarted the router (IB) (power off, wait 10s, power on)?

@Fliossapa82

Which internet box (router) do you have?

Normally you can enter 192.168.1.1 into Internet Explorer to get to the login page.

Exactly @Fliossapa82,

Simply connect the PC to the router (if you want it to be connected to the Internet, then it should already be connected 😉 ) and then you can directly access the link I shared above. Enter the password and username according to the information from @WalterB and voilà.
