A red x appears in the network icon tray and the "Networks" flyout hangs in Windows 8 or Windows 8.1 when you have 300 or more access points

Applies to: Surface ProWindows 8Windows 8 Enterprise

Symptoms


Consider the following scenario:
  • You are using a computer that is running Windows 8 or Windows 8.1. 
  • There are 300 or more 802.11 (wireless) access points available, as might be seen in a test lab.
In this scenario, a red letter x appears in the operating system network icon on the task bar for about 30 seconds, and the Networks flyout hangs for about 30 seconds.

Cause


When there are lots of access points, an NDIS driver may report that uTotalNumOfBytes of OID_DOT11_ENUM_BSS_LIST is larger than 60,000 bytes.

Resolution


This issue is not seen in a typical environment and has been observed only in a laboratory environment. NDIS drivers should limit the number of bytes that they report so that the total for uTotalNumOfBytes of OID_DOT11_ENUM_BSS_LIST stays under 60,000.

More Information


This situation occurs only in stress environments.
