    Q: When connecting to BSAP-18XX with Realtek Wireless Adapter, why I am able to pass traffic for 2-3 minutes and then I am no longer able to pass any traffic?

     

    A: ADTRAN has had several reports of various Realtek Wireless Adapters (rtl8192e, rtl8188ce, rtl8191se) exhibiting these symptoms. Troubleshooting revealed the Realtek Wireless Adapter going into a power save mode (SM Power Save) that is not supported by the AP. The client should not go into this mode unless the AP advertises that it is supported. In some cases, upgrading to the latest Realtek driver sourced directly from Realtek has resolved the issue. ADTRAN has found that some laptop manufacturers, Toshiba for example, have posted outdated drivers that do not include a fix for this issue. Here's the link to download the latest driver directly from Realtek: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=2&PNid=21&PFid=48&Level=5&Conn=4&ProdID=272&DownTypeID=3&GetDown=false&Downloads=true

    It appears some Realtek Wireless Adapters have the fix included in the latest driver, while others do not. First try upgrading to the latest driver. If that does not resolve the issue, another work around is to disable 802.11N on the Realtek wireless adapter until Realtek releases a driver for your adapter with the fix.
