I recently bought an Archer C7 router which I use in Access Point mode to boost the wifi from my crappy Sky router. I also bought an RE300 to extend the signal into my office as my PC wasn't getting a good signal.

This all works fine, but I am getting logged out of certain sites daily. For example Hotmail. I check the box to keep me logged in, but every day I need to sign back in. I also have 2 factor enabled so I need to use my authenticator app every single day as well. It happens with other sites that I use the authenticator with too. My tv in the bedroom (which also uses the RE300) also needs to sign up to the internet every time I turn it on.

Do you have any ideas why this would be happening?
