How do I know if my wireless system is secure?

How can I check my system to see if my wireless is secure? If someone can't use it is close.

Use appropriate encryption method, if your devices support WPA2. WEP is already broken, do not use it.
Use strong passwords, 16 characters or more. The more the better, use lower & upper case, numbers & Charachters like () * & ^ % $#! in combination.
Add all the mac addresses of your own devices to the trust list, & enable mac filtering
Finally and most importantly, change your password from time to time.
In addition, in most of the home modem-routers you can check what Macs are connected to your network, make sure all the Mac there are yours.

    How will I know if a connection site is secure? In Safari or Explorer there is a locking visual icon in the web browser window, but not in Firefox. Is there an add-on that meets this need?

    The padlock shows only that there is a secure connection and does not guarantee that you are connected to the right server. So you could always be connected to the wrong server if you make a typing mistake in the URL and someone said that mistyped the URL. The lock feature has been replaced by the identity button of the Site on the left end of the address bar (address).

    The Web site I will use frequently requires 128-bit encryption. He mentioned using https: instead of http. How do I know for sure the site is secure? I searched the padlock at the bottom of the screen and once that wasn't there the next time here.

    The lock is no longer a part of Firefox; It can give users a sense that a site is secure by not providing all the information related to a site. Familiarize yourself with the Site identity button in Firefox:

  • Satellite P20-604 - how do I know if it has a wireless card or not?

    I have a P20-604, which I think was not preinstalled with a wireless card. Just to make sure that my details are:

    Model No.: PSP20E-0Du43-G3
    Serial No.: 14735613G

    If she does not have a wireless card, how do I determine what parts to buy so I can set up a wireless connection?

    Thank you.
    Seem

    Hello

    As far as I know that the wireless card is optional on this unit. This means you have the opportunity to upgrade the unit with the wireless Mini-PCI card. At the bottom of the unit, you will find a machine slot for this card.

    Please visit this site to check what wireless card is compatible with your device:

  • P3K49EA: How do you know which wireless adapter you have?

    Hey,.

    I was looking at the Wi - Fi drivers for this specific unit but for many other portable, I can find the drivers for the network for a series of adapters Wi - Fi, like Intel, Realtek, and Qualcomm.

    Many times, a way to solve the problem of falling of the internet is now by installing the last Intel Wi - Fi and Bluetooth card, but there are other drivers for the cards made by other manufacturers, how do I know for sure that my device has a processor intel Wi Fi adapter?

    I don't know that, in some cases, you can check back and see exactly which wireless adapter you have, but who are these dependent region?

    For example. each laptop, Pavilion, envy and water courses that are sold to the United Kingdom, all have an Intel wireless adapter? and if it was a laptop computer with an AMD processor and chipset?

    Really looking forward to hearing from you guys.

    Thank you

    Steven

    I suspect that you have installed the Realtek wired ethernet driver and Intel wifi driver. Only the driver for the hardware you have installed. In fact, the tag on the laptop won't tell you much. If you look to the top of the support page for your specific model, it will show the drivers for all the optional features available in this series of models. And Yes, the wireless cards can be region-specific. The regulation on radio communication varies around the world. That's why several wireless drivers are listed, some of which you can't use. Unless you are having problems just use office supplies Windows driver. If there is a problem, it may be necessary to know your specific hardware so that you can find a more specific driver from the manufacturer's Web site, or you can search the Internet for other people having a problem with this specific device and use other suggest drivers. I hope that this is a logic.

  • How can I know if someone is trying to hack into my system?

    Original title: Hackers

    How can I know if someone is trying to hack into my system?

    If you see something strange, like move your mouse, you windows open randomly. In some cases, you may not notice anything.

    I suggest to do some checking, first run Windows Update and install all updates, if your system is outdated, it is easier to get hacked.

    Other than Windows, you must ensure that other applications on your PC are updated such as Java, Flash Player, and if any application asked for the update, please do.

    Make sure, of course, install Anti-Malware software and update it.

    Run a full system scan with:
