Hi,
I've got a customer attempting to activate on a system with an Intel BE200 wireless adapter and seeing Error 34. We are using TA 26.0.2.0, and I have tried fixing the WMI using the steps in the FAQ. Get-WMIObject MSFT_NetAdapter -Namespace root\StandardCimv2 runs fine without error, and I have this output saved and am able to email it to you if helpful.
Kind Regards,
Joe
Have they also updated their network adapters? The version numbers should be in the log. If they've updated, send the log. If not, have them update first.
