The Acer has a Qualcomm Atheros QCA61x4A Wireless Network Adapter. I have attached the network diagnostics report generated by Windows. I checked with Acer and the driver is current. The older Lenovo thinkpad edge as a Realtek RTL8188EE wifi adapter. I have the Acer on a lot of networks this year (30+) and have never had this problem with any other network.
