I have a E430 running windows 8.1:
Driver info: PCI\VEN_14E4&DEV_4727&SUBSYS_060814E4&REV_01\4&1BEFDF2B&0&00E1
My wifi connection is just not working properlly. When I was running with windows 8, it works fine.
Has anyone have a updated driver for this , for Windows 8.1? The current one available from Lenovo website is not working for me.
Thanks in advance.

I'm also having problems with wifi after upgrading to 8.1 on my E545.
Wifi is struggling to reach 1mbps download while my other laptop side by side is getting 80mbps.
Silence from Lenovo so far.
Any help or suggestions would be greatly appreciated.

Did you try deleting the Broadcom wireless device in the Device Manager (including deleting drivers if prompted) and rebooting? I just did a fresh re-install of Win 8.1 (not "Refrsh - I mean format and install from scratch) and it works fine with the driver Windows 8.1 installed automatically. If possible, connected via a LAN cable after you reboot and then try to install the driver using Winodws Update.
I think that version is actually newer than the one listd in Lenovo System Update so I've just been using the one Windows installed automatically. For me, up thru Winows 8 this device driver was not available through Windows update and had to first be installed manually.
