Sounds like it’s an issue with your router configuration and NOT your steam deck. If you have tethering on your cell phone you can use it temporarily to test if you get Wi-Fi that way, though I wouldn’t download anything over it if you have a data cap.
Since it sounds like your ISP has complete control of your router I would call their customer support and let them know you have a device that cannot connect. Most likely they’ll either do something like a factory reset on the router or ask for specific hardware information (like the MAC address) about the device you’re having trouble with (in this case your steam deck) so they can check the setting and ensure it isn’t blacklisted or something.
If they for some reason still won’t help or can’t get it fixed, you can always go out and buy your own router and hook it up. You’ll still have to contact your ISP again to get it setup but at least you’ll both have full control over the router configuration, and you won’t have to pay a monthly fee to rent a router from them.
EDIT: You may also be able to factory reset the router yourself. They usually have a pin hole in the back or something you can press with a paperclip or needle that will factory reset them when held down for a few seconds. Keep in mind anyone else connected to the router will have to redo all connections for all of their devices.
