• How can I secure my laptop when I surf the internet via a public router at work?

  How can I secure my laptop when I surf the internet via a public router at work? I mean if I use a router to work and others use too and I use a private laptop! I heard that someone hase the knoladge he can enter my laptop the couscous that he uses the same router I do. you have a special program for that, or is there a place in my computer that I need to enable to avoid the unwanted entries?

  If your Windows is updated and your Windows Firewall is enabled and that you have updated anti-virus, that would be fine. In Windows 7, you must check Action Center in Control Panel to see your security status, if something is wrong that it will show a message in Windows XP and Windows Vista, he calls the center of security.

  They may only enter your laptop or hack, if your firewall is disabled or there is a vulnerability in your system or a Malware would cause of vulnerability, and in all cases to ensure that your Windows updates and anti-virus is running, you are protected.

  Another thing is that if your router requires the password, then choose strong password and change it regularly, if it is public without password or authentication, then you need to careful when visiting Web sites because they could be monitor and publicly display information. Some websites have encryption that in Internet Explorer, it shows as a lock icon pad indicating that your transaction is encrypted and you're safe.

  It depends also wireless encryption in your company that will be in service by admin or SOUND Department if it's WPA2 which is good but for WEP or WPA, you should be very careful. I suggest to discuss this issue with your COMPUTER service too.

• XPS M1330 can not find network card after reinstalling Windows Vista

  Hi all

  I'm passing my computer to a member of his family and wanted to give them a new installation, so I used the disc of Windows Vista (32-bit SP1) shipped with the laptop and reinstalled Vista on the computer. Everything worked fine until I wanted to connect to the internet, then Windows tells that there are no available networks. When I chose "Why doesn't windows find all networks" he stated that "this computer doesn't have a wireless network installed and configured card". I put in the Dell driver and Utilities CD that shipped with the computer and installed the drivers which seemed related to networking or communications, but the problem persists. I guess it's some sort of driver problem (as the computer used wireless before the reformat (a few hours ago) and so the device itself seems to work.)

  I would greatly appreciate any help to get this race. :)

  Thank you!

  Hi Chris,

  Please share the system model and the operating system installed on your computer?

  If you are facing problems with the wireless, you can follow the steps below to check if the drivers are listed as installed in the Device Manager:

  • Press 'Windows' + 'R' key on keyboard.
  • Type "devmgmt.msc" into the box run without quotes.
  • In the Device Manager window, expand network adapters and verify if your wireless card is on the list.

  If the wireless driver is not present in the system and is displayed as a network controller in the section other devices with a yellow question mark, you can download the drivers from the link: http://dell.to/QjjZDA -> Enter-> the serial number of your system, select the operating system-> expand the category network to download/install wireless drivers

  I hope this helps. Please respond to the findings.

• NB200 can connect to wireless networks, but cannot connect to the internet

This week, I am away from home and discovered that while I can still connect to a number of different wireless networks, I can't connect to the internet with Internet Explorer.

  If he has problems with the update or the permissions then simpler is to download the full version and trash the version currently installed to do a clean install of the new version.

  Download a new copy of the Firefox program and save the file on the desktop disk image (dmg)

  • Trash the present application Firefox to do a clean (re-) install

• Since I've upgraded to internet explorer 8, he can't see that I'm connected to the internet

  I have upgraded to internet explorer 8, but now unable to connect to the internet using my wireless connection.  Wireless has excellent resistance and worked very well with the previous IE.  I tried to reinstall and the same problem occurs.  It does not seem to accept as a connection.  The computer is windows xp. I put internet explore in the firewall exceptions.  When I open the browser, I get the connection to diagnose button and when I push it says an error has occurred because it is not able to diagnose the problem, but it does not say what is the error or how to fix it.  Is it possible to go beyond that, or I'm stuck using an earlier version of Internet Explorer?

  Thank you
