WPA2-Vulnerability (For Wireless Routers, USB adapters)
Buffalo Inc. is aware of the recently publicized security exploit "KRACKs".
Since this vulnerability depends on the client function of the WPA 2 standard, it affects wireless USB adapters and bridge mode (WB and WDS, etc.) of wireless routers that support WPA 2.
Buffalo is investigating its product line to determine which products may be affected by this vulnerability. As the investigation progresses, Buffalo will update this public release with information about affected products.

If you are not using the bridge mode (WB and WDS etc.) with the wireless router, it is not affected, so you can use it safely as it is.
Please confirm the following points as to whether or not to use the bridge mode.
(The confirmation method differs for some products, please refer to the explanation about the bridge mode of each product manual.)
- *If you set the unit rear switch to "AUTO" at the time of product setting, the bridge mode is not enabled.
- *If you set the unit rear switch to "MANUAL" at the time of product setting, and "ROUTER" or "AP" is selected with the switch, the bridge mode is not enabled.
