Issue reliably connecting Thinkpad T470s, running Windows 10, to wireless network automatically

2018-04-27, 19:32 PM

Howdy folks,

 

We have a new rollout of laptops with Win10 that we want the machines to grab the network as soon as they come up so our co-workers can log right in. We have a CA that our ISE service checks before sending to DHCP for addressing and AP allocation. We are seeing intermittent and inconsisent successful connections, every machine in our test group has failed auto connect at least once.

 

Things we have tried:

Making sure power settings are set to best performance

Turning off Fast Boot

Disabling Hibernate

Latest Intel WiFi drivers

Latest Lenovo power management

Win 10 build 1709

 

We have also done some network traces to watch the traffic and see if there was anything glaring that would tell us why the connection would not initiate. We are kind of at our wit's end and could use a few extra eyes/minds on this.

 

Let us know if we can provide anything else and we will see what we can do!  :-)

 

Thanks in advance for any help.

 

-brad and the team

Ok gang,

After multiple rounds of tests, poring through logs and applying modifications of all your suggestions, we found a reliable answer to our issue. We ruled out drivers, added software, patches, the CA and even ISE and the APs. We went back to the client build and recalled(found) we had added(enabled) some registry keys way back in the beginning of our testing. This had been done to more or less slow the client down so the network could properly authenticate them. Since testing began the network team has made some updates, upgrades and improvements and the artificial pausing is no longer needed.

Thanks for taking a look and if you have questions please reach out. Have a great day!
