Packard Bell Laptop: Frequent WiFi Disconnection on Windows 7 Ultimate SP1 64bit - Solutions

Hello!
I have a problem:
For some time now, the laptop has been losing its connection to the WiFi network. It happens that you do this five times a day. Sometimes the problem does not occur, the lottery. When the laptop is disconnected from the network, it should be put to sleep and then restarted. Then there's the internet again. I am sure about the router, it works great on other devices. What's up? What to do with this?

Laptop info: (anything else you will need?)
-Packard Bell
-Windows 7 Ultimate SP1 64bit

Maybe try on other drivers. How exactly is losing? What does it display when you try to connect after something like this without putting it to sleep? Update the BIOS, though I doubt it will help.

The connection simply disappears. The laptop does not detect the WiFi network, and at the same time other devices read the network perfectly. No message appears, if the internet was "from the cable" it is like disconnecting the cable, it simply disappears. BIOS up-to-date.

driver problem in my opinion. Why? Because I have the same (Zenbook Asus UX31A).
As long as I had Win 8.0 with WiFi there were no problems. After upgrading to Win 8.1, WiFi "breaks".
Then it only helps to run the auto-repair - card reset (and there is a default gateway - before it was missing).

See if resetting the WiFi card helps you? If so, this clue will be confirmed.

I have reset the card, now it remains to wait. Thank you anyway!

Check on other drivers, as I wrote above.

will solve the problem for 1 time. But it will probably still exist. Go back with the controls - as your friend suggests - and see.

But maybe first take advantage of:
-----------------------------------
"Control Panel" -> "Administrative Tools" -> "Computer Management" (run as administrator).
Now in the program (Computer Management) select -> "Event viewer"
On the right you have the "Overview and Summary" window. Select Window -> "Summary of administrative events",
and from him -> "Bugs". Find the DHCP-Client (1002). Double click. A window will open. There you will find the details of the problem.

ps.
I have something like this:
DHCP 192.168.0.1 refused to lease the IP address 192.168.0.6 for the network adapter with the network address 0xCxxxxxxxxxxxx
(The DHCP server sent a DHCPNACK message).
