Thinkpad T480 and Intel dual band wireless ac8265 issues

Hello everyone!


I recently got myself my first thinkpad, a t480! I love the machine so far and i didnt not have any issues until the last few days!

All out of a sudden my wifi is completely unusable and im becoming desperate since i have tried out various attempts to fix it, but none worked!

What happens, is that the wifi just keeps disconnecting permanently. It keeps the connection for maybe 1 or 2 minutes, then disconnects and after a few seconds, reconnects to the wifi again! It is literally unusable like that and i cant return the laptop to the manufacturer since im using it for my university and have a lot of important programms and data on it, i need it daily.


Here is a small list of what i have tried so far:

-reinstalled the drivers for the device

-optimize the power settings

-forbid windows to turn off the device to safe power

-tried various drivers


I could not come up with more solution attempts to that issue. Right now i am even thinking about just buying a new WiFi card for the Laptop (is it swapable in a t480? or is it integrated?)

If you need further information to help investigate the issue please let me know!!!


I hope there is another way to resolve that issue!

Looking forwards to your help Smiley Happy

Try to disable the adapter' power saving feature in Device Manager

You might check here for a newer version of the driver:


I have found that the right-click from device manager is sometimes not up to date ...

(an example being the WiFi driver on a Lenovo Ideapad just earlier this morning .... ;-/

I was having similar issue but mine I would be able to connect but every like 20 minutes or so it shows that im connected to wifi but nothing would load up. I went to Control Panel\Network and Internet\Network Connections and I realised I have vEthernet enabled too ( cuz I enabled Hyper-V ) and I was getting 2 connections one was Ethernet and the other was WiFi, I disabled the vEthernet and it seem to solve the problem.



if you have such similar thing, i'll keep on digging for solutions and i'll update you.

What's DOS?
