帮助 Ubuntu 18.04 的 wifi 适配器

我只是用 Gigabyte Z390 Designare 构建了一个桌面。我已经设置了双启动 Windows 10 和 Ubuntu 18.04。

我能够连接到 Windows 中的 Wifi。带有 Intel CNVi 9560 的板载 Wi-Fi 适配器。

但是,Ubuntu 没有检测到网络适配器。

我运行了代码,但没有看到无线适配器。非常感谢一些帮助,以便我可以开始使用 Linux

出错后如何重新配置​​wifi?

  • 1

在过去的一周里,我的 wifi 受到了严重影响。非常慢的速度和很多中断。我知道发现问题出在调制解调器而不是 Ubuntu 上。

与此同时,我使用这个答案删除了我的英特尔驱动程序并重新安装它。但它失败了。它让我没有功能驱动程序。我尝试运行 modprobe,重新安装内核,将驱动程序的备份文件复制回来,均无济于事。

现在我没有网络适配器,也没有功能驱动程序。

如何将系统恢复到原始状态?

Intel Centrino Advanced-N 6235 蓝牙延迟

不知道为什么,但是当我尝试在完整安装的 ubuntu 16.04 上运行蓝牙(我有我的理由)时,蓝牙会加速并减慢并无法控制地跳过,而我可以找到的调试日志中没有任何解释(尝试将 bluetoothd 设置为-d 模式,但它吐出的东西太多,我无法全部整理。)无论如何,这是唯一让我无法享受这台电脑的东西。

(顺便说一句,蓝牙在实时模式下可以正常工作,但不能在完整安装中)(另外,wifi 也可以正常工作。)

编辑:蓝牙现在也不能在实时模式下工作。

修复慢速 WiFi 的正确方法

我有一台笔记本电脑 - Jumper EZBOOK 3 PRO。
它具有无线适配器 - Intel® Dual Band Wireless-AC 3165。
我已经安装了Ubuntu 18.04.1 LTS,并且遇到了 WiFi 连接速度超慢的问题。并且使用Windows 10
没有问题。

我找到了修复 -禁用 802.11n。
但这不是一个好的选择,因为我仍然没有最高速度。我想让 802.11n 正常工作。

所以问题是 -还有其他解决方案吗?
例如,更新内核或以某种方式安装正确的驱动程序或使用 NDISwrapper。
你能建议我做什么吗?

PS我已经尝试修复驱动程序,但没有成功。我还检查了 802.11ac,它工作正常。
PSS 我已经启动Manjaro并且遇到了同样的问题。

我安装了英特尔 wifi 8265 卡。我还为该卡安装驱动器。但是我无法获得超过 54M 的速度(54M 是 N 的限制)我知道该卡可以做 AC(最高 867M)。为什么 Ubuntu 拒绝以 AC 模式连接?我有几个网络N,AC。我什至无法连接到交流网络。如何解决?

网络随机挂起

  • 1

我遇到了一个很难诊断的网络问题。

一天大约两到三次,网络将完全停止工作。我的意思是 ping 返回:

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
From 192.168.125.134 icmp_seq=1 Destination Host Unreachable
From 192.168.125.134 icmp_seq=2 Destination Host Unreachable

有时运行ip命令只会挂起。systemctl restart networking没有效果。唯一的解决方案是重新启动机器。

有趣的是,这只发生在我的工作网络上,而不是在家里。

我在稍旧的(2016 年?)戴尔 XPS 13" 上运行 Ubuntu 18.04(通过升级过程)。我尝试了更新的内核(目前在 4.16.7-041607-generic)和各种 wifi 驱动程序。问题同时出现在 wifi 上运行和使用以太网时。

有什么建议么?有什么我应该看的吗?

另外,如果有人能弄清楚我的wifi卡应该使用哪个ucode,我将不胜感激。我的无线网卡是 Intel Corporation Wireless 8260(rev 3a),内核是 4.16。

上次发生这种情况时,我仍然能够运行ip route等。结果似乎表明我正在失去与网关的连接:

为运行route而不是ip route.

更新 2:

ip addr两人又ip route开始挂了。这是 strace 的输出:

$ strace ip route
socket(AF_NETLINK, SOCK_RAW|SOCK_CLOEXEC, NETLINK_ROUTE) = 3
setsockopt(3, SOL_SOCKET, SO_SNDBUF, [32768], 4) = 0
setsockopt(3, SOL_SOCKET, SO_RCVBUF, [1048576], 4) = 0
setsockopt(3, SOL_NETLINK, NETLINK_EXT_ACK, [1], 4) = 0
bind(3, {sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000}, 12) = 0
getsockname(3, {sa_family=AF_NETLINK, nl_pid=7214, nl_groups=00000000}, [12]) = 0
sendto(3, {{len=40, type=RTM_GETROUTE, flags=NLM_F_REQUEST|NLM_F_DUMP, seq=1539085900, pid=0}, {rtm_family=AF_INET, rtm_dst_len=0, rtm_src_len=0, rtm_tos=0, rtm_table=RT_TABLE_UNSPEC, rtm_protocol=RTPROT_UNSPEC, rtm_scope=RT_SCOPE_UNIVERSE, rtm_type=RTN_UNSPEC, rtm_flags=0}, {nla_len=0, nla_type=RTA_UNSPEC}}, 40, 0, NULL, 0

我开始认为这是我笔记本电脑底座的硬件故障。以前我对此打了折扣,因为无论我通过扩展坞使用 wifi 还是以太网都会发生挂起。这是我的家庭设置(不会挂起)和我的工作设置(会挂起)之间为数不多的不同之处之一。

更新 3:

我购买了一个新的 USB 集线器/坞站,但它仍然会发生。我原来的底座可以使用 5v 电源,所以我会看看这是否有帮助。

更新 4:

电源没有帮助。但它似乎已经停止发生,或者至少已经显着减少了频率。我没有更新内核,但我认为 Ubuntu 为戴尔 XPS 推送了 Thunderbolt 固件更新,这可能起到了作用。
