Very simple connection process, no PC or login to the website needed. The most difficult thing is for me to look up my own password : ) - it uses the same password as the main Wi Fi. I tested as far as my detached garage in the back of my house and now I have internet there. I am buying one more unit for my son's room

It works well enough for the kids to stream Disney plus on one tv and for my daughter to do homework on her laptop but that's it. Does not offer the speeds advertised but I don't want to waste my time and money sending it back. Spend more money. This is definitely a piece of hardware where you get what you pay for.
