• Wireless network connection problem

  Nice day

  I have a wireless network connection problem and I ask for help to resolve.
  What surprises me that this problem appeared suddenly, I used to connect to the WIFI correctly but two days ago my laptop could not connect to the WIFI and more.

  Other devices and computers connect with success so I think that the problem in my laptop.
  I don't have any changes on my laptop or windows, antivirus, drivers... updates or installed new software.
  Troubleshooting of Windows detected 'router or access point issues '.
  -Reset the router does not resolve the problem
  -Network adapter is enabled.
  -State of wireless card "working properly" and "update".

  I read a solution on this site, which was to change the properties of the wireless adapter, but the changes mentioned does not appear in the pilot of my laptop...

  * My laptop info. :
  DELL INSPIRON 3521
  Windows 7-64 bit
  Dell WIreless 1703 802.11b/g/n(5.2GHz)

  Sorry for this long to make, I appreciated all the help.
  Thanks in advance.

  Hello

  Have you tried to reset your laptop to a time before this issue started with a Windows 7 Restore Point?  If it is a parameter change or software this restore point can help solve what is at the origin of the problem.

  I'd also, of course, when you are resetting the router, to make sure that you let it sit for at least 30 seconds to a minute before plugging power back in.  You may need to do a few times to clear his memory to be able to connect.

  In addition, have updated the drivers for the wireless card?  What version of driver currently installed in the system?  You can consult our support site, enter your serial number and click on drivers & Downloads to find the driver for your wireless card.

  Finally, have you tried to empty the wireless profiles that are currently stored in your system?   If you delete the profile current wireless (which is to control your connection to the router), reboot your system, and try to reconnect Windows will rebuild the profile and hopefully allow you to log in again.

  I would like to know if any of this helps.  To help resolve this more effectively please click on my user name Dell Todd and send me a private message with the Number of Dell Service from your system.  Please keep all troubleshooting and discussions on this thread open so that others can find the information they need to solve their problems.

• Home wireless network connection problems

  What should I do if I normally connect to the wireless network does not appear?  It is not a network card problem, because I can connect to other wireless and school and other places.  I tried to reset the router, ping and by unplugging and seeing what I could understand on the computer at home, but nothing does.  Any ideas or suggestions would be greatly appreciated.

  Thank you.

  Unplug the modem and Router 3 + minutes. And then reconnect the modem - when it is running
  Plug in the router - when it is running - restart the computer. This is known as a hard reset.

  Check with your router manufacturer support.
