嗨,
我发现英特尔双频无线-AC 7265与Extreme Networks无线接入点存在不兼容问题。 只有在无线接入点上启用快速漫游(802.11R)和受保护管理帧(PMF)时,才会发生这种情况。 其他无线产品, 苹果ipad和三星手机使用相同的设置工作正常。 无线捕获显示,当在WPA2企业上启用802.11r和PMF时,运行Windows 10且采用Intel双频无线-AC 7265(驱动程序版本19.51.14.1)的Lenovo T450无法关联。 无线接口确实成功完成了radius服务器的身份验证,并继续进行4次握手。 但是,在4次握手的第二个消息中,无线客户端在RSN IE中插入了2个字节,移动了PMKID的位置。 验证者检查M2中的RSN IE与关联请求中的RSN IE不同,并解除客户端的关联。 该检查是根据ieee802.11i标准章节“4-Way Handshake Message 2”进行的,该章节表明了这一点 “... 2)如果MIC有效,则Authenticator按位检查RSN信息元素 匹配来自(重新)关联请求消息的消息。 i)如果这些不完全相同,则Authenticator使用MLME-DEAUTHENTICATE。 请求原语来终止关联。“ 有人可以看看这个。 谢谢。 以上来自于谷歌翻译 以下为原文 Hi, I've observed an incompatibility issue for Intel Dual Band Wireless-AC 7265 with Extreme Networks wireless access point. This only happens when both fast roaming (802.11R) and Protected Management Frames ( PMF) enabled on the wireless access point. Other wireless products e.g. Apple ipad and Samsung phones works fine with the same setup. Wireless capture shows that when both 802.11r and PMF are enabled on WPA2 enterprise, Lenovo T450 running Windows 10 with Intel Dual Band Wireless-AC 7265 (driver ver 19.51.14.1) cannot associate. The wireless interface did finish authentication with the radius server successfully and continue with the 4-way handshake. However, in the second message of the 4-way handshake, the wireless client has inserted 2 bytes in the RSN IE shifting the location of the PMKID. The authenticator checks that the RSN IE in M2 is different from that in the association request and disassociate the client. This check has been done according to the ieee802.11i standard Section "4-Way Handshake Message 2" which states that "...2) If the MIC is valid, the Authenticator checks that the RSN information element bit-wise matches that from the (Re)Association Request message. i) If these are not exactly the same, the Authenticator uses MLME-DEAUTHENTICATE. request primitive to terminate the association." Can someone look into this please. Thanks. |
