How insecure is an unsecured wifi connection?

When you sign to a non-secure network connection (say McDonald's) - how unsecured is - this about someone see my information?

For example, if I had to put a password - is this visible to anyone who attempts to get information?

What about using something like GoToMyPC where my home computer comes to my remote computer screen?  If I work an unsecured connection, can someone hack info from my computer?

Thank you!
Annie

Completely uncertain. Never do anything important or requires a security when you're on a public wireless network. MS - MVP - Elephant Boy computers - don't panic!

    Hey nic,.

    You must give us more details about your problem. Your explanation is very deep and so it might be a little hard to give exactly the instructions how to resolve you this problem.

    First you make sure if your wireless network card is listed in the device correctly without yellow exclamation point Manager.
    Then, make sure that the WIFI is enabled with the hardware switch and FN + F8.

    You see the WLAN router if you are looking for WIFI networks at your fingertips? If so, can you connect or you get an IP address?
    Also check the DHCP of your laptop configuration and disable the Save function in the energy WLAN Vista power management.

  • Satellite M50 161 - how to set up the WIFI connection?

    I use my Satellite as a second computer. My PC is primary and is using a NETGEAR card.

    I used a card reminder in wireless cards because my home office is a bit far from the PC.

    Of course, my laptop has its own part of the ways to get online.

    I've always taken for granted connection. I don't even remember the 1st time I am connected. In fact an engineer could have done to the delivery!

    PC had problems connecting. Host Web server problems. I was expecting sort of my laptop to connect in any case, as it could / should connect to it's own wireless installation to get online. I'm not an expert as you realize.

    It dawned on me while I had no idea how to switch on and connect using the built-in wireless card that not Netgear obviously. Or I'm expecting a lot and the lap top is actually a slave to my PC connection and always will home in on the netgear connection.

    BTW, I'm back online via the netgear but would like to know. Excuse my ignorance...

    To be honest I m a bit confused.
    I put t know exactly what you want to do.

    If you want to connect to the Wlan router and then activate the wireless card on the laptop with the WLan switch on the side of the laptop and the FN + F9 key combination.
    Then configure settings such as the SSID, encryption, Mac address, etc. by using windows has the configuration settings or 3rd party software like utility Intel ProSet or Atheros client utility (depending on the Wlan card).

    Hello

    Go to your router admin pages...

    • Click Start, type cmd, and then on enter.
    • In the black window resulting type ipconfig and press to enter.
    • The router admin pages is accessible by ip address which is defined as the value default gateway for the network connected to your router device.
    • Open a browser and type http:// (the gateway ip address is in the format x.x.x.x, where x is a number, probably 192.168.x.x).
    • This should open a login page of your router. A user name is admin. typical passwords are password, admin and blank (no password).
    • If the user name and passwords you try do not work, see the documentation or go to your router manufacturer's website help pages.

  • How to change a unsecure network connection?

    Because I'm not sure which router you have that's going to be quite general.

    Click Start, go in run, type "CMD" and in the command prompt, type "IPCONFIG" no citation.

    Find the address of a default gateway and enter this address in the address bar of your web browser. You will be asked to enter a user name and password. It is common that it is admin/admin, admin/password, admin/1234. After getting that distant and connected, an update so that we can better you go after knowledge that makes your router. If you happens to go there and feel comfortable going forward, look for the wireless settings tab and there should be a sub-category of security. Use WPA2-PSK, whatever you ask for password will be your new password in order to access your wireless network.

  • How to put a WIFI-connect button directly on the home screen?

    Hi all

    I know there is a wifi - connect button in the notification Panel, but I have to turn on my screen, open the Control Panel, then click on the "quick settings" button, then click on the WiFi connect button... " 4 actions connect within my own wifi network!

    (Note that I don't want the automatic connection setting because I don't want to be connected to each time)

    I wish I had just a "wifi - connect ' on my screen which allow me to connect just by clicking this button."
    I can't find a widget or application in my phone to do this.

    Do you know how?

    Thank you very much

    Hello

    The best thing would be to follow the advice of dandy63of s, by downloading a third-party application that can handle it. The closest you can get this as standard (without having to download any third-party application), would be to add a shortcut to settings > Wi - Fi. This can be if you long press on an empty space on your home screen > select Apps > shortcuts > settings > Wi - Fi.
