If a network of neighbors appear on my list of WiFi in the about this Mac, should I be concerned about security?

I am trying to solve a network problem.  In the process, I was browsing the WiFi networks listed in the report of the system slot on my Mac.  I found all my networks expected but also found a network I won't name My Next Door neighbour.  Although I've seen this network on my computer when you connect to one of my networks (and thought it was simply a neighbor whose own network was narrow and strong), I was surprised to find it in a list on the WiFi system report page.

I don't know if I'm too react or should deal with this neighbor might somehow be surfed on my internet account and/or have access to sensitive information on my computer.  My network is secure with WPA2 Personal.  So the neighbor.

Thanks for any idea that you can provide.

Jim

In the report of the system, the network of my Next Door neighbor is listed under the current information network or other local Wi - Fi networks?

Current must be the network you are on, and it should be your own. If my Next Door neighbor is under another heading, it's OK. This means that it is available, but you are not connected to it. On my Mac, the other category is all of my neighbors, about 10 of them. Other is like all networks not selected under the Airport icon in the menu bar, they are of no interest because you are not connected to them. They are like the list of the radio stations on your radio, they are listed because you're within range of them, but they can't touch you. Unless you are connected.

  • Why I still see other appearing in my list of wireless network connection when network discovery is turned off?

    Why other users who are are my nearby?

    Can I be sure that they cannot see me when discovery of the network on my computer is off?

    Should I worry about these other users?

    I am the only computer in my home group, and my wife uses a Tablet using my wireless network key. but no one else has access to my home group.

    Discovery Network turns off the discovery of other devices that are already inside your trusted network (like your TV system game, tablets, phones and other computers).

    It does not affect the list of wireless network connection, which is actually just a list of wifi nearby broadcasting system has found.  You can not turn off without turning off your wifi.  But this isn't a security problem.

  • A user network folders that appear for all users

    So, I have one that I'm stumping. I work in a school with a portable one-student-per-computer program. I created images for several models of computers and they deployed on the student machines. I did this with my login.

    Now that school has started, I noticed that several times when a student logs on their computer, they see a list of my network disks. They do not have permission to access the drives. There is a group policy in place of our network admin, who is supposed to let students see their own network drives, but these do not show up until you manually disconnect each of my network drives.

    The systems were Sysprep before the image was captured.

    I think there must be a copy cached my network disks resides somewhere in the picture, who gets shot in the images get deployed. I looked under the C:\Users\Default folder to see if I can find something here, but I couldn't. Google searches do not seem to be much help either.

    Anyone have any idea?

  • How to uninstall an add-on that does not appear on my list?

    When I go on my Facebook page, part of it has a message that maybe reading "ads go to save" a hundred times on the page. If I click on a photo or something, "ads browse for save" will reappear, as long as the window is open, it is almost impossible to comment/read of other comments. I clicked on the link and it brought me to browsetosave.com which gives instructions on how to uninstall from firefox.

    The PROBLEM is that 'Browse to save' does not appear on the list of extensions/add-ons/plug-ins. It's happened before with an 'ad' different Web site and I had to uninstall/reinstall firefox. I was hoping to not have to do it again, especially since I don't know what is the cause. I would like to make the screenshots (although I don't see where to add it).

    Any help would be appreciated!

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do not click on the reset button on the start safe mode window or make changes.

    Do a check with some malware malware, analysis of programs on the Windows computer.

    You need to scan with all programs, because each program detects a different malicious program.

    Make sure that you update each program to get the latest version of their databases before scanning.

    Alternatively, you can write a check for an infection rootkit TDSSKiller.

    Hello

    I don't know if I understand your question, but you want to connect two laptops via the WLan. Am I wrong?
    Well, this type of network connection is called Ad hoc.

    Choose Start-> settings-> network connections, and then click the local network connection you want to share. On the left side of the screen under the management of the network, click on "change settings of this connection. Under the Advanced tab, under Internet connection sharing, check the box "allow other users of the network to connect through this computer's Internet connection".
    There is also a check box to allow other users to enable or disable the Internet connection, if you are so inclined. If your network doesn? t need to access to the Internet, you can skip this paragraph.

    The host system must also be configured with an Ad Hoc network connection and a Set Service identify (SSID). Right-click on the wireless icon in the system tray and choose "view wireless networks". Do NOT yet connect to any wireless network that could appear in the box. Click the Advanced button. This will bring up the Properties window of wireless with the wireless networks tab at the front. Click the Advanced Options button at the bottom right of this tab, select the option "networks from computer to computer (ad hoc) only". Make sure that the box "Auto connects to the non preferred networks" is NOT checked. Click the close (once) button to return to the wireless network tab.
    Under preferred network, click Add. You now need a SSID for this machine, which is actually the name it will use to announce themselves to the other members of the ad hoc wireless network.

  • Home network not working not not because of 'ComputerName' not in the list of shared folders.

    My simple home network of 2 PCs with XP, SP3 and a Netgear WNDR3700 router was working fine. I changed ISP and now cannot get the home network to the top. Run the home networking on every PC wizard implements the internal IP of 192.168.1.1 for the router and 192.168.1.2 and 192.168.1.3 for 2 PCs. Shared folders and files appear to be configured correctly and successfully, I can ping the router and the other PC from each PC. After the Microsoft troubleshooting procedure, everything is good until I get to the stage where the "ComputerName" must appear in the list of shared folders in computer management, System Tools, shared folders, shares. All other devices and shared folders appear correctly on each PC. It is about the last step in troubleshooting, but I can't in front of her. What can I do? Or is the wrong thing? I'm almost to the point of thinking there is something in the registry (added with my ISP change process) that stop working. Help!

    In general, it is due to a firewall, in which case advice Jack will help.  In addition, there are a condition [rare] where the Type of a computer node becomes defined 'Counterparts' or 'P Pei' that will stop the communications between computers.  Bring up a command prompt (start-> Run-> "cmd") and enter the command:
    ipconfig/all

  • Realtek network controller Not found. If hibernation mode, please plug the cable

    I had this error before. I understand that it is the controller not to wake computer recovery. At the time where it happened the first time (several months ago) I accepted it as being dead. 3 days ago, I decided to update my drivers, including the network driver and like magic, my internet works again. I went to bed last night, (do not remember if I tried to shut down my computer) and came this morning to the screen stuck on the screen saver. After a hard reset, I'm back in the same boat. This error appears when I try to repair/reinstall the Realtek Ethernet Controller driver. Windows repair thing when I click on the currently connected to comes up with cannot find a network card or something similar.

    THINGS I'VE TRIED (in every imaginable command):
    -Disconnect the power supply for 30 minutes
    -Remove the CMOS battery for 30 minutes
    -Remove my RAM for 30 minutes (with the CMOS battery and separately)
    Reinstall/Repair of the driver
    -Reset the default bios settings
    -Hit my head several times on the table
    Implies that I agree that the map was dead was fine, until it worked magically for a day. Any help would be highly appreciated!

  • iOS10 WiFi keep forgetting about the hidden network

    I am on iPhone 5 iOS version 10.0.1 on the T-Mobile network. In my workplace, we have hidden wifi network. It was working fine. But after my upgrade to iOS 10, the continuous phone to forget the network hidden whenever it goes to another network wifi (for example at home). Other colleagues who has iPhone 6 or 6 s has any problems. Any help is appreciated.

    Hello prasenjit.oracle,

    From your post, I see that your iPhone is not able to re - connect automatically to a hidden wireless network after you connect to another network as your home Wi-Fi. I know it's a practical function, so I can see why you would be tender hand to help solve this problem. I'm happy to provide advice!

    As a first step, I would recommend that you restart your iPhone before you test the issue again. If the problem persists, I would recommend that you reset the network settings. To do this, go to settings > general > reset > reset network settings. This also resets the Wi - Fi networks and passwords, cell parameters and VPN and APN settings you used before.

    See you soon!
