Hi ornella2904 ,
Welcome to the Community Forums.
What Windows version would you be using?
Assuring that you have already installed all remaining updates for Windows can assure that there are no current downloads or installations currently being processed in the background.
Technical Support are the best guys to consult regarding WWF00F008-UL7VBE as it would need specific tool to decode it and if this would relate to current slow performance.
Setting the power option not to save power on the properties of the wlan card under device manager can help maximize wireless usage.
Update us how it goes.

I will state what the code means:
w=windows, l=linux, U=UEFI
008=return code of test
UL7VBE is a hash code of your machine's serial number used in Lenovo Feedback data collection... Ignore this.
I suggest your google search the Realtek driver noted in your screenshot.
I would also visit www.realtek.com and find the newest driver for your wifi.
If you go into device manager, locate the wifi, right click properties, then...
wiggle thru the tabs for the device id, and post it here, that would help.
The device ID could be under events, power management, or -other.
After best driver is found, and still Error via LSC, report back what you see.
