Wife does much of her work at home.

Employee came over with her laptop for meeting. she wanted to connect to our wifi.

Wife gave Router password.

I suppose network may now be compromised. As a novice, what is my next step (and how is it done)?

Thanks

How would the network be compromised? if all they did was connect to it and use it it shouldn't be compromised, if you mean how to change the password that's an entirely different process. would you mind elaborating on what you meant when you said " I suppose network may now be compromised"

You're right.  Did not think this through...lack of familiarity and experience being a novice.

 

I guess the worst that could happen is that he parks outside and leeches bandwidth.

I do not know your router, however, most routers' passwords can be changed through its menu.  Viper_Security, I have a question for you because you are very knowledgeable about security matters:  Would anyone's wifi security also depend upon the Network and Sharing Center's Changed advanced sharing settings?  I ask because at school, my laptop has all those settings off with password on, and suddenly no more "seeing" other people's devices in my Explorer's left column.  Means they can no longer "see me" either?

Wi-Fi security No,

if your network and sharing center settings are turned off you can no longer see people connected to the same LAN and vise versa, if it's on you can see other devices that have their sharing turned on as well.

 

However if someone has connected to your network before and they do as the OP had mentioned and leech off Wi-Fi, if both parties have sharing turned on, then you can,1. see the person(s) connected to your network via the computer name under the "Network" tab in the left hand menu in FileExplorer. and 2. View their files that have been allowed to be shared (they also can view yours if your sharing is turned on)

 

So if you're worried about that, the solution is simple, change the Wi-Fi password via the Router Gui :)

You're right!  Windows "told" me the same thing that you told me:  anyone already connected before settings were set of OFF are not affected by such changes.  I will remember to do my settings before allowing coffee-shop wifi, which is easy to do, all I have to do is use Windows Firewall to block everything temporarily.

Getting back to thread starter -- would thread starter be better off to change wifi router password AND write that password into a locked-drawer paper&pen notebook?

Some routers have the ability for a guest network. This is a separate wireless network name that your guests would connect to with a separate password. That way you could just disable the guest network when they aren't over and the guests would have no info on your private wireless network. Further, access between computers on the guest and private networks can be restricted for privacy reasons, but this stops the guest from using your printer.

 

Besides that, it is a good idea to change your password about as often as you change your toothbrush. This is easier said then done, but solves a lot of the more common router vulnerabilities.

(1) Would anyone's wifi security also depend upon the Network and Sharing Center's Changed advanced sharing settings? I ask because at school, my laptop has all those settings off with password on, and suddenly no more "seeing" other people's devices in my Explorer's left column.

(1) That's one of the security issues, that most people don't know when using public WiFi.

(2) Well, not completely, with the appropriate network software, this opens other doors.

Trikein, I have a Netgear 7550 AT&T DSL modem, do you know where I could start looking for such an option?

Doesn't look like that model has it. 7550 is a rebranded Westell that only has basic features. Are you using it as your wireless router?

 

Here is a example of a router that does have it, the Asus RT-N66U.
