Hi, Pilgrim Plaza.
I feel your pain.
I wanted to stay connected to family and friends while walking the Camino. I even wanted to blog while on my journey. All this meant I needed to figure out a way to stay connected to cyberspace, without adding a major amount of weight.
One of your messages implied that you want to connect from a friend's house. I assume that this friend has internet, either wirelessly or with a cable. If you are planning to stay there for a short time, just use his/her laptop.
However, if you plan to stay there for a length of time, you want to connect your own laptop to the internet so you don't have to depend on/bother your friend every time you want to go on line.
First, does your laptop have internet access at home? Do you use a wireless connection or do you connect using cables?
It sounds like you use cable. Nowadays, most laptops are capable of connecting over the internet wirelessly, even if you normally use cables. This is what Wifi is all about.
You can find out whether your particular laptop can connect wirelessly pretty easily - contact me and I'll be happy to help you out (or at least send you in the right direction).
If your laptop connects wirelessly, a screen will probably pop up somewhere on your monitor when it "senses" that there is a wireless internet connection floating around somewhere in the neighborhood.
If your laptop cannot connect wirelessly and can only connect with cable, a notice will also pop up automatically when you cable it in and it senses a connection available.
Your laptop is like a bloodhound which picks up an "internet connection scent" in spite of what else it may be doing and will let you know. It is one of the things laptops are designed to do automatically, like automatically changing the time and date.
There are several levels of privacy with internet connections.
1. There are public connections, which are easy to get into but are public. You don't need a password for this. However, you don't want to do anything that you want to keep private while using a public internet connection because people you don't know may be able to access your stuff. When using a public internet connection, be especially aware of closing/signing out completely and carefully. I agree with SY who advised you to get software that helps keep bad guys out. Public internet connections are how people can use their computers at Starbucks, McDonald's, and many other places (internet cafes) that have free WiFi.
2. There are "secure" internet connections. If you use a secure internet connection, you need a password to "get in" or "unlock the door." You might even see a little picture of a lock on the screen. All you need to do is get the password and type it in when your computer asks for it. This is more secure but definitely not perfect. Also, sometimes these connections are not free.
Let's go to the bigger question of why you want to take a laptop with you in the first place? Big, heavy, vulnerable in many ways (stolen? lost? broken?).
Your friends here on the Camino forum can give you better advice if you give them a better understanding of your situation. It seems complicated but it might be easier than it appears.
Hope this helps but sorry it went on for so long.

PS - I ended up taking my smartphone and my iPad. And I know many here would argue about my having taken either. But they met my needs
PPS - If your friend
does not have internet at his/her home, you have run into a whole new set of circumstances (my Mom doesn't have internet at home and it's a challenge for me when I visit). If that is the case, just ignore everything I've said in this posting.
