what happens when you connect with wireless

you see the wireless on the list
you choose to connect
it asks you for the password
you enter password
it connects
and you get internet access

at what point does it not follow those steps ?

do a tcp/ip reset

For Windows Vista through to Windows 10
Start> Programs> Accessories> and right click on Command Prompt, select "Run as Administrator" to open a command prompt box (A new dialogue box - black with white font, will appear on the screen ):​

For Windows 8

In the command prompt window that opens, type the following commands:

  • Reset WINSOCK entries to installation defaults: netsh winsock reset catalog and press enter
  • Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log and press enter
  • Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log and press enter
ReStart (reboot) the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start> Programs> Accessories> and right click on Command Prompt, select "Run as Administrator" to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

Thanks for your timely reply...
After entering password windows displays message "Windows was unable to connect to xxxx network".

I have already mentioned that I did a tcp/ip reset in my initial post.
Anyways, I have done it again and here are the results.

You must restart the computer in order to complete the reset.


C:\Users\xxxx>netsh int ipv4 reset reset.log
Reseting Global, OK!
Reseting Interface, OK!
Reseting Unicast Address, OK!
Restart the computer to complete this action.


C:\Users\xxxx>netsh int ipv6 reset reset.log

shame , that can often resolve the issue when the password is put back on

- try safemode with networking (sometimes wireless does not work with safemode )

For Windows 8 - see below

For other windows version, XP,Vista, W7 as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works

For windows 8

Install or reinstall the latest wireless driver from the PC manufacturer's web site.

Were you ever able to connect to said wireless network with this computer?

if a laptop or mobile device - see if it will work at a cafe/library or other wifi hotspot

------------------------------------------------------------------------

Uninstall and allow windows to re-install the adapter and Driver
goto the device manager > Network Adapters > click on the [+] to show all the adapters

right click on the adapter and from the menu

remove/uninstall the adapter

Now restart the pc and allow windows to detect new hardware and re install the adapter and the driver
------------------------------------------------------------------------

otherwise

all i can think to do now is reset the router as suggested - see if you can connect to it with no password
