All my devices seem to have problems connecting to my homes router. This problem appears only on linux and only on my router. All other networks work flawlessly. My router is a CH7466CE.
EDIT: My router seems to have unfucked itself.
What have you tried so far?
manually setting my ip usually fixed it, but not this time
Do you have a VPN running on those devices to the same network that you are trying to connect to?
Had something like this using WireGuard once
The way I usually use cable internet, is to connect another router via ethernet to the cable modem/router, and then connect all my devices to that second router. This way, I could use the provider’s router (sometimes the model they provide can’t be changed), and at the same time use a better router for my devices.
