Wireless Access Problems with Multiple Anti-virus Programs
If a client is unable to connect to wireless networks or can only connect with limited access and it is verified that the client has wireless access, it may help to check the client’s anti-virus programs. Sometimes having multiple anti-virus programs installed on a computer will cause interference and may block access to services, such as wireless.
Additionally, there is a Chinese anti-virus program that has the number 360 in it that often will lock down wireless access. If the client can change some of the settings, that may work. The easiest solution for this is asking if the client is comfortable with switching to McAfee because of this known issue with wireless access.
Both of these issues usually impact not all BU wireless networks, not just BU (802.1x).
