X1C6 ; Wi-Fi gateway unavailable after resume from Modern Sleep ; package 21.20.0.0u build NZ4W803W

Hi.

 

I have recently installed the latest Intel 8265 Wireless LAN Driver for Windows 10 64-bit, package 21.20.0.0u build NZ4W803W (autoinstalled by Lenovo Vantage this week).

I have noticed since this update when I resume from Modern Sleep, the WLAN gateway is unavailable, no network access.

I have to restart manually (disconnect/reconnect) the Wi-Fi in Windows to restore gateway/WLAN access.

 

I have reverted to the driver version 20.70.7.1 (from Windows Device Manager), and it seems to work normally.

 

Does anyone encounter this problem with the latest update ?

How can I report this problem to Lenovo engineers ?

 

Thanks.

Wifi disconnects when left idle

Hi,

My brand new X1 carbon disconnects from the wifi whenever is left idle. The wifi does not come back even after I wakes it up unless I manually get the connection back on again. Everything is updated and I thought the wifi power management setting might be the problem. But there is no power management tab within the network category as there was in previous versions of windows 10.

I have the same issue on 20.70.10.2 (newest driver, at least from Window's point of view). 
I just got rid of Modern Sleep, as it's causing TONS of problems with this laptop. With standard S3 everything works fine (and it's still very fast), so this whole S0i3 sleep is a small price to pay, to have a well-functioning laptop.

20.70.10.2 is the new driver version included in the package 21.20.0.0u build NZ4W803W.

I have tried the classic S3 sleep before but it was quite slow on my X1C6 (30-60 sec. to sleep), maybe I will try it again soon.

Thanks for you reply.

When my new Gen 6 Carbon X goes to sleep, internet is disconnected when I wake it up. None of the online solutions apply, this version of Windows does not have the options that the online solutions show.

Same here.  After the update, Device Manager showed the WLAN driver as 20.70.10.2.  I reverted to the 20.70.9.1 driver (obtained from Intel website), and that has solved the problem for me.

Received the brand new machine 3 days ago,  have to disconnect and connect wifi everytime after waking from sleep mode,Super annoying,

 

Tried to upgrade the Intel AC8265 driver to 20.70.10.2 , still the same.

 

Already checked all battery/energy/network setting in Windows 10.

 

any solution?

Re: X1C6 ; Wi-Fi gateway unavailable after resume from Modern Sleep ; package 21.20.0.0u build NZ4W8

I just started to notice this issue as well.

 

According to Lenovo Vantage, my system installed the latest WLAN 8265 driver on June 25th, V.21.20.0.0u.

 

I was very confused because I couldnt' find this driver on Intel's own website, it just now is posted up on July 2nd.

 

I was hesitating to try to install the older driver straight from Intel until I confirmed other people were having the issue and it wasn't due to something I had done. It looks like a problem that existed at the start of the year has come back. There were a number of forum posts around January - February 2019 for this issue on an older driver version.
