Disabling Internet connection via Ethernet cable

[HeavenlyGifted]

Since I can't exactly get the appropriate way of searching for this in Google.

I would like to ask for help here, if somehow someone could understand what I'm trying to ask for.

I want my router to function only as a WiFi and technically not let anybody connect through an Ethernet cable. since it is really annoying how it disrupts the way the frequency of the WiFi or the bandwidth distribution.

Could you provide as much detail about your router as possible?

Brand, model number, etc.

A touch of superglue and blank connectors work to block use of the ethernet connections. LOL
