X1 Tablet Wi-Fi no internet on wake from standby

2019-07-30, 11:54 AM

Hello, I have a ThinkPad X1 tablet 20GG001KUS, all drivers are up to date, however, within the last month or so I have a problem with no Internet connection after waking from standby mode.  To fix this I either have to run the network troubleshooter which resets the Wi-Fi adapter or disconnect and reconnect to wireless network.

 

I am running Intel graphics driver 26.20.100.6859.  Attached is additional information.

I had a similar problem on my X1 T3 (20KJCTO1WW), when waking from Sleep. 

Method 1: Reset TCP/IP Stack and auto tuning on:

has worked for me, so far.

 

This was suggested in another thread similar to this one:

I had this after a recent update.  The quick fix was to revert the driver (Windows 10, Intel 8265 adapter, revert to version 20.70.11.3).

 

Can somene explain what the "Reset TCP/IP Stack and auto tuning on" tweak actually does?  What is auto tuning in this context?

 

Incidentally, when this happens then faster than using net diagnostics to reset the adater is the following pair of commands, executed from a command shell with admin privileges (or a batch file):

netsh interface set interface "Wi-Fi" DISABLED
netsh interface set interface "Wi-Fi" ENABLED

 

 

This assumes your wireless device is named "Wi-Fi".  You can get the name of the interface with:

netsh wlan show interfaces

Nice find!  It looks like this behavior is explicitly addressed in Lenovo driver 20.70.11.3, released 1 Aug.  I didn't try it because my reversion to an earlier driver has been functional.    I see there is also a driver version  21.40.2, released by Intel on 8 Oct.  which is supposed to address this problem.

 

As a rule of thumb, before installing new hardware drivers make a note of the old one if it is functional, in case you need to revert.  This is sometimes hard in W10, which tries to update your software while you are not paying attention.
