[Update 17-Jan-2015] This issue seems to be resolved in the January 2015 firmware update (at least for me): firmware update details.
A post about a non-SharePoint subject: issues with limited connectivity using WIFI on the Surface Pro 3 after putting the Surface in sleep/hibernate state. A lot of posts are already done and Microsoft already released multiple fixes, but for a lot of Surface users it doesn’t fix the issue.
This post describes a workaround to automatically reset (stop/start) the WIFI connection when the Surface is started from sleep/hibernate:
- First you need to enable script execution via Powershell: Open Powershell and execute the command: Set-ExecutionPolicy Unrestricted
- Create a new Powershell script on C:\ (e.g. restartwifi.ps1)
- Add the following command: restart-netadapter -InterfaceDescription ‘<your wifi card name>‘ -Confirm:$false
You can find your WIFI card name via Device Manager -> Network adapters.
- Create a new Scheduled task via Task Scheduler
- Give the task a name, for example: “Restart WIFI after sleep or hibernate”
- Set it up to run as the “SYSTEM” account
- Under the “Triggers” tab, add a new Trigger
- Begin the task: On an event
- Go to the “Actions” tab, add a new Action
- Action: Start a program
Add arguments (optional): -File “C:\restartwifi.ps1”
- Under the “Conditions” tab, uncheck the “Start the task only if the computer is on AC power” checkbox, otherwise this workaround will only work when your Surface is charging
- Click OK and save the scheduled task
- If you run the scheduled task you can see that your WIFI adapter is restarted next to your system clock
- Now put your Surface to sleep/hibernate and start it up again. The limited network connection issue is now fixed 🙂
