We have seen an issue with Windows 10 on the zSpace AIO systems with serial numbers starting with ZW3xxxxxxx where some customers have reported intermittent loss of their wireless network connections. When checking their network connections in the system tray, the system will show no wireless connections available.
One potential cause we have seen is that the Broadcom 802.11ac network adapter on Windows 10 appears to have issues with low bandwidth and weak signal strength, which causes the network adapter to try to reset itself. When it does, it may intermittently malfunction and no longer is able to connect to a network.
The first workaround is to reset the wireless adapter by disabling and re-enabling the wireless connection. To do this, use the following steps:
- Click on the Windows Start icon in the bottom left corner of the screen and select Settings.
- Select the Network & Internet and then select Change Adapter Options.
- Select the Wi-Fi network connection, then right-click to select Disable.
- Again select the Wi-Fi network connection and then right-click to select Enable.
- Exit out of the Window and see now if you can re-connect to your wireless network.
Other Best practices
Ideally, this issue can be mitigated by providing strong wireless signal strength (attenuation) and stable, reliable bandwidth to the zSpace 300 systems. There are a variety of ways this can be achieved.
- Create a non-broadcasted VLAN for zSpace units. Prioritize the non-broadcasted VLAN before non-critical broadcasted VLANs.
- Filter Network Access by MAC Address.
- Adjust the Output Power of the AP.
- Adjust bandwidth frequency.
If the first workaround does not resolve the issue or the issue persists, the next step would be to remove/uninstall the current driver and rollback to an older Microsoft Network Driver. This will not impact performance in any way and may improve the stability of the network connection. To do this, please use the following steps:
- Right-click the Start Windows icon in the bottom left corner.
- Select the Device Manager option.
- Locate and expand the Network Adapters.
- Right-click the Broadcom 802.11ac Network Adapter and then select Uninstall Device.
- Select the checkbox that says Delete the driver software for this device, if available, and then select Uninstall.
- When complete, close the window, and restart your zSpace system.
- Once your system is back to the desktop, go into the Device Manager, locate and expand Network Adapters and make sure the Broadcom 802.11ac Network Adapter is under Network Adapters.
- Verify that the driver version is now 22.214.171.1246 (6/2/2013) by right-clicking the Broadcom 802.11ac Network Adapter, device, select Properties, then select the Driver tab.
- If everything looks correct, you can now go and reconnect to your wireless network. If you are seeing a different driver version and date other than what is listed in step 8, repeat steps 1-8 again, making sure to check the box to delete the existing drivers as shown in the screenshot in step 5.
- The workaround is complete.
If you have difficulty completing these steps or the wireless connection disappears even after trying both of these workarounds, please contact zSpace Customer Support for further assistance.
