Hi all.

Hello alexytfc

Thanks for using the Lenovo forums.


Sounds like might be a power setting issue.

 Unfortunately searching around the net didn`t provide much insight into it either.

 

Try some of the following:

Download the WiFi and Chipset drivers for the unit from the support page. Make sure to reboot after an update on the unit.

 

Make sure you have your Power Settings in the Control Panel set to the maximum performance when on battery, see if that is able to make any difference,

 

 

See if you can reset IP/TCIP stacks:

 

Step 1. Click the Start button
Step 2. In the search box, type "Command Prompt"
Step 3. Right-click Command Prompt

Step 4. Click Run as administrator
Step 5. Type "netsh winsock reset catalog" and hit Enter
Step 6. Type "netsh int ip reset reset.log" and hit Enter
Step 7. Restart your computer

 

 

See if you can flush the DNS:

 

Step 1. Click the Start button
Step 2. In the search box, type "Command Prompt"
Step 3. Right-click Command Prompt

Step 4. Click Run as administrator
Step 5. At the command prompt, type "ipconfig /release" and press Enter

Step 6. Type in the command "ipconfig /flushdns"

 

 

 

Hope these help, let us know how you get on.
