WiFi connection problems after upgrade to Windows 10 - Thinkpad Edge E545

I have upgraded my Lenovo Thinkpad Edge E545 to Windows 10 recently and since then I have been having increasing problems to connect to WiFi. It is not a problem with the WiFi itself, since I can connect with my phone and tablet without any problems and my husband has not had any problems with his laptop either. It started with just having to try to connect a couple of times (clicking disconnect and then connect again) in the beginning. Then it took restarting the computer. And now I can't connect anymore no matter how often I try or whatever I try. Initially I got an error message regarding the IP address when using the troubleshoot, but now it just can't find the problem. I have read that it could be a problem with the WiFi driver, which may need an update for Windows 10. The driver listed is Realtek RTL8188E LAN 802.11n PCI-E NIC. I have not been able to find this driver or any update for it on the Realtek website. I have not been able to find anything on the Lenovo or Windows website, or anywhere else for that matter, either. I have read posts by other users who are having similar issues, but I haven't been able to find a solution.

Please let me know how I can solve this problem. Thank you.

Dear KVW,


Welcome in lenovo community,

Lenovo did not release all windows 10 drivers for the E545 laptop yet,

So you may go back to the previous windows and wait till lenovo release all the drivers.

Also you can use the below link to follow the drivers update,

I just tried to download the lastest system drivers, no change.  I even installed the 'System Update' utility and it installed all the latest versions of the Lenovo drivers and software.  Even updated the BIOS and EC, no change.

My laptops will be worthless unless I can upgrade them to Windows 10 by Summer.  I have about 65 of these.
