Connecting to a wifi but not others

So my laptop won’t connect to my wifi at home but will connect to my university wifi and other wifis, however at home, all my other devices and family’s devices are connected to the home wifi with no issues… when I troubleshoot it, it says I need to plug in an ethernet cable but thats not really practical for me to sit next my router if I need to use it at home… Any help would be fantastic! Thanks in advance x
