Lenovo G560 Wi-Fi Problems [ Edited ]

[patricke]

Hello,

I have a G560 and experiencing problems with my wifi under Windows 7 64bit. I can connect to a wifi without any problems. However, after a period of time I get the message "restricted connectivity" for my wifi connection and the connection does not work anymore. Laptop will also reacts really slowly then, all sounds are weird and I get a blue screen sometimes. I have the newest bios and installed the newest broadcom driver I could find: date 15-02-2011, version 5.100.235.19.

Furthermore, I already unchecked the device settings "allow  the computer to turn off this device to save power" and set maximum performance for the wireless connection under the power options.

Regards,

Patrick

make sure that you entered the password correctly also try to reset the modem.

As I wrote I can connect without any problem.

That's not the problem. After a period of time, I get a restricted connectivity all of a sudden. I don't know why, but it is not a configuration problem of the wifi network.

try to use manual ip configuration instead of dhcp.

[patricke]

That did not help. The connection still breaks after 45 minutes. The router settings cannot be the problems, because all other pcs work properly within the wi-fi.  Also I am getting sound problems right after the connection is getting constraint and the pc is responding really slowly.

check if the issue persists with lan.
also, updating drivers may help you to solve the issue.

With a cable connection, lan, everything is fine. I use the newest driver I could get from here http://consumersupport.lenovo.com/ge/en/DriversDownloads/drivers_list.aspx?CategoryID=67873 . In my opinion it is very strange that the sound breaks too, when the wifi gets problems. I looked it up and they are both on the same irq. Could the problem be related with that?

did you un-checked "save power option"?

[patricke]

I deactivated the "Allow the computer to turn off this device to save power" options for the wifi device

[yigit]

did it work?
