Lenovo U350 - Windows 7 - Network (LAN, WiFi) not working

[sergei85]

HI

Today I installed Windows 7 (professional edition) on my Lenovo U350 notebook. Everything works okay except network devices (LAN, WiFi, WiMAX), Bluetooth is working ok . I tried to install drivers from official site (http://consumersupport.lenovo.com/en/DriversDownloads/drivers_list.aspx?CategoryID=61415), but without results (windows reports errors)

I tried to install:

• Broadcom Ethernet Driver
• Broadcom Wireless LAN Driver

Please help me!

press fn + f5 to activate wireless and make sure the wireless switch is on.

then, select the correct drivers from download page. you said you tried to install broadcom wireless but are you sure you have broadcom wireless? possible intel?  plus, please send the errors you got.

I also had problems with the LAN-driver, but eventually I found it on Broadcoms homepage. http://forums.lenovo.com/t5/IdeaPad-Y-and-U-series-Laptops/U350-Broadcom-Gigabit-not-working/m-p/169...

yigit, I have "yellow error messages" in Device Manager near WiFI, LAN, etc.

xloserx, thanks for your reply! LAN is working now!

But wireless devices (Bluetooth - exception) are still not working now

I have yellow marks in Device Manager (sorry, some items may be different in the English version (I have - Russian version)):

• Intel WiMAX Link 5150
• Unknown device
• Ethernet Controller

Can you help me?

Hi - good to hear that LAN (Ethernet) is working now. You could try the wifi-driver found here: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18747&ProdId=2957&lang=eng

For the unknown device try the Lenovo Energy Mangment Driver: http://consumersupport.lenovo.com/en/DriversDownloads/drivers_show_1814.html - should fix it.

Hi,

I have successfully installed Bluetooth, LAN and WiMax drivers, but WiFi still not working now

I have yellow mark  in Device Manager near "Ethernet Controller".

When I press fn + f5 "parameters of wireless devices Lenovo" window appears. I turn on the "wireless network adapter", but when I try to configure a new connection in "Network and Sharring Center" I can choose only "the connection via DSL or cable ..."

p.s.

Lenovo Energy Mangment Driver I have already installed.

[yigit]

try to re-install wireless adapter drivers.
