Signing into XBox from my Laptop

Also is there anything preventing you from taking the Ethernet cable from the laptop and plugging it into the Xbox or do you have to "sign in" on the laptop to get a connection, if so do you only sign in once and that's it or each time you want to connect

My xbox is not letting me sign in to xbox live but i can sign in on my laptop why is that?

having a similar problem but no error code. somehow today my profiles and all my games and other saved data were wiped and could 't even try to sign in to xbox live when attempting to download my profile. I had changed my password on live on my laptop and
verified it was changed. It will let me sign in on my laptop but not on my xbox 360. keeps telling me that the password is incorrect but I know it is correct because it lets me sign in on the laptop.

on the windows laptop, sign out of the xbox app, sign in with the ultimate sub account, download whatever games they was from gamepass, sign out of the xbox app and back in with their account and they can then play those games.

I signed up to xbox live and got a silver membership on my laptop, giving me this profile that you see. I just hooked up my xbox to the internet and i want to put my profile from my xbox onto this account.
