无法在Ubuntu 15.10,华硕ZenBook UX305上使用英特尔AC 7265连接wifi

我已经阅读了一些关于类似主题的post,但没有一个能解决我的问题。 我2周前买了笔记本。 在遇到第一个wifi问题之后,它已经有好几天了。 但现在,我几乎与Onboard wifi卡Intel AC 7265有任何联系。我试图将这些行添加到/etc/modprobe.d/iwlwifi.conf:

options iwlwifi 11n_disable=0 

首先我认为这有帮助,但我只是一次又一次得到wifi密码请求。 但现在它和以前一样,无法连接到Fritzbox Cable 7360。

接下来,我在日志中找到了这两行:

 [ 1.601664] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-15.ucode failed with error -2 [ 1.601682] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-14.ucode failed with error -2 

我从https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware获取了这些固件文件,并将其复制到/ lib / firmware。 没有效果。

你建议什么解决方案再次连接wifi。 我使用的是USB wifi适配器,但它的工作速度很慢,而且连接经常中断。

[编辑]根据要求,ls -al / lib / firmware |的响应 grep 7265:

我从github复制了文件:iwlwifi-7265-14.ucode iwlwifi-7265-15.ucode iwlwifi-7265D-14.ucode iwlwifi-7265D-15.ucode

哦,我认为你是对的。 文件很小。 我从github获得了html而不是文件。 ;)

[编辑28.01.16]我家附近还有很多其他的WLAN。 路由器显示其他30个wifi信号。 其中大部分都在11频道,也是由我们自动设定的。 总共有13个频道,其中一些频道当时没有被其他频道使用。 是否建议切换到这样一个未使用的频道?

请安装最新的7265固件。 从终端:

 sudo apt-get update sudo apt-get install git git clone https://github.com/OpenELEC/iwlwifi-firmware.git cd iwlwifi-firmware/firmware sudo cp iwlwifi-7265* /lib/firmware 

校验:

 ls -al /lib/firmware | grep 7265 

重新启动并告诉我们性能是否得到改善。

检查路由器中的设置。 WPA2-AES是首选; 不是任何WPA和WPA2混合模式,当然也不是TKIP。 其次,如果您的路由器能够达到N个速度,那么您可以在2.4 GHz频段中使用20 MHz的信道宽度而不是自动20/40 MHz进行更好的连接,尽管它可能会影响N个速度。 我也有更好的运气,固定频道,1或6或11,而不是自动频道选择。 此外,请确保路由器未设置为仅使用N个速度; 自动B,G和N是优选的。 进行这些更改后,重新启动路由器。

接下来,我建议明确设置您的监管域名。 检查你的:

 sudo iw reg get 

如果你得到00,那就是一个大小也许适合所有的设置。 在这里找到你的: http : //en.wikipedia.org/wiki/ISO_3166-1_alpha-2然后暂时设置它:

 sudo iw reg set IS 

当然,如果不是冰岛,请替换您的国家代码。 永久设置:

 gksudo gedit /etc/default/crda 

如果您没有文本编辑器gedit,请使用nano或kate或leafpad。

将最后一行更改为:

 REGDOMAIN=IS 

仔细校对,保存并关闭文本编辑器。

接下来,我在网络管理器中将IPv6设置为忽略: http : //docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png此示例用于以太网,但你想要无线。

如果这些更改无效,请尝试:

 gksudo gedit /etc/modprobe.d/iwlwifi.conf 

更改您添加的行, options iwlwifi 11n_disable=0到:

 options iwlwifi 11n_disable=8 

仔细校对,保存并关闭文本编辑器。 重启。

对于那些拥有英特尔NUC的人来说,请记住,糟糕的吞吐量是由于英特尔7265芯片的设计不好,如果打开蓝牙,它会干扰WiFi信号,因此很简单,关闭蓝牙。

有同样的问题,禁用powersave为我工作:

iw wlan0 set power_save off
