WiFi very slow to reconnect (if at all) after sleep or hibernation

Hi

Nice work on trying to get it going.

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

A general comment .

We all have a general problem. There are many 3rd party applications that when installed and used insert themselves into the Network components of Windows, some of them also alter the default of the configuration. Most of these applications are Not thoroughly test. They are tested to work but usually it is on some simple standard system. it does not tested and take in account the hundreds of iteration of End-Users Network configurations with its wide variety of Hardware and other Network related applications.

Among these applications are 3rd party security suits, Network Managers, 3rd party network related wizards, Virtual applications, users playing around with settings found over the Internet with limited info about what they actually do, and many more.

To complicate the issue, some of these applications load process at startup and interfere with the Network even if the application is Disabled, or and Uninstalled.

I found rather known 3rd party Network application that use to leave around 100 entries in the registry, and an Undelete-able icon on the Desktop after it is Uninstalled.

As sad, as it is at times the only functional solution is Re-Install of the OS to brink it back to standard status.

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

As for Power Saving there might be more settings.

Look at the Laptops BIOS too, some of them have hardware embedded scheme.

Also look at the StartUp and Processes to make sure that there is no 3rd party utility involved in the WIFI mangement.

This can help to find out.

Assuming that the signal is strong, and that there is No electrical environmental noise.

Check the Computer's support site and make sure that you are using the latest Drivers*** for the Network cards.

Check the Router's support, and make sure that your using the latest firmware for the Router.

Uncheck the Network Card's Power Saving (I.e., do not let the card save power).

There might be some variations on where the Power saving setting is.

Here are few examples, YMMV, look around in your systems.

***On  Drivers Update .

Try to install the latest drivers of the card from the support page of the  manufacturer.

Download the drivers and unpack them to a folder of your choice.

In the Device manger, right click on the adapter.

Click on Update Drivers, and choose the Browse my computer for drivers,

Choose let me pick from a list, Click on  Have a Disk and point to the folder with the Drivers.
