我已经为此奋斗了一段时间，不知道如何解决。我读过许多其他帖子关于这个话题，但没有任何解决方案可以帮助我。
以下是我的问题的简短版本：我可以扫描网络但无法连接。
我以前也连接过，但信号强度很弱。一旦我将机器移离路由器（<3 英尺），我就再也无法连接了。
以下是无线脚本的输出：

我已经尝试了optionsin的各种方法/etc/modprobe/iwlwifi.conf，但它们似乎并没有真正起到作用。目前这个文件看起来像：
# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system. When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211
options iwlwifi 11n_disable=1
任何帮助将不胜感激！
更新 我继续更新到 15.10，看看新内核是否有帮助。卡仍然表现相同。
根据建议ubuntuforums.org，我继续尝试反向移植的固件 (17)，因为它应该可以提高此卡的可靠性。同样没有任何改善...

基于此关联Intel 为这款 wifi 卡认证了内核 4.2。是的，有一些解决方法可以尝试，但这可能会暂时有所帮助。请参阅我的线。
我有 Intel AC 3165，我尝试用变通方法让它在 Ubuntu Desktop 14.04 LTS 上运行......取得了一定程度的成功，但连接每隔 10-15 分钟就会断开一次。
最后我升级到了带有内核 4.2.x 的 Ubuntu Desktop 15.10，之后运行良好。
您也可以选择将 Ubuntu 14.04 LTS 中的内核升级到 4.2。但您需要为其他应用程序进行工作。我相信升级到 Ubuntu 15.10 是值得尝试的，因为下个月升级到 16.04 LTS 很容易。
