No internet access with KPN router

[hansa123]

Hi there,
I'm visiting a friend in the netherlands atm and I want to connect my Mint 20.2 MATE x64 Laptop to a KPN Experia Box. The strange thing is: both WIFI and cable fail. I can access the admin control panel with the given IP, but no website is loading and ping always fails. On windows 7 on the same laptop, it works fine. What is going on here?

Ping to what always fails; to name, IP or both? If ping 8.8.8.8 works it's a DNS issue: have you configured custom DNS on Linux? I.e., perhaps your router back home?

Thanks for your reply. 8.8.8.8 fails as well as any URL. I installed this Mint just a week ago and it worked fine with various wifis. Now with this router, neither CAT5 nor wifi work, which is really confusing to me. Other hardware works fine with this hotspot so I am not sure what can be the cause. Apparently it must be the interaction of the hotspot and Mint since Win 7 works. Anything else I could try or test?

Am afraid I've little useable suggestion. Given that W7 on the same system works it must be system-sides; given that it's both Wi-Fi and ethernet and specific to this connection it's not a hardware/signal-strength issue; DNS was denied. Any suggestion I have boils down to Linux-sides setup but given that you installed it only recently I would assume you'd remember setting up a VPN that denies access from your location or some such.

I.e., sorry; no idea. Scrounge around your networking settings...
