无法在 hp pavilion 中的 ubuntu 16.04 中启用 Ralink wifi

无法在 hp pavilion 中的 ubuntu 16.04 中启用 Ralink wifi

我知道这个问题以前已经被问过,但是到目前为止还没有任何答案,我会链接我尝试过的所有线索。

问题

但首先出现的问题是,我的 wifi 突然停止工作,当我尝试启用它时,发生了以下情况:

在此处输入图片描述

正如你所看到的,当我尝试启用 wifi 时,它又滑回来了:

诊断

以下是我运行的一些诊断程序:

遵循问题,我运行以下代码

rfkill list

打印了如下内容:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

并运行这个

ip link

打印如下:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether a0:1d:48:f8:ad:c9 brd ff:ff:ff:ff:ff:ff
3: wlo1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 48:5a:b6:c4:9c:93 brd ff:ff:ff:ff:ff:ff

然后我运行关联:

首先是这段代码:

lspci -v 

打印了此内容

02:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe
    DeviceName: Ralink RT3290LE 802.11bgn 1x1 Wi-Fi Adapter
    Subsystem: Hewlett-Packard Company Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 Combo Adapter
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at b2410000 (32-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: rt2800pci
    Kernel modules: rt2800pci

以及以下代码:

sudo lshw -C network *-network 

打印了如下内容:

Hardware Lister (lshw) - B.02.17
usage: lshw [-format] [-options ...]
       lshw -version

    -version        print program version (B.02.17)

format can be
    -html           output hardware tree as HTML
    -xml            output hardware tree as XML
    -short          output hardware paths
    -businfo        output bus information

options can be
    -class CLASS    only show a certain class of hardware
    -C CLASS        same as '-class CLASS'
    -c CLASS        same as '-class CLASS'
    -disable TEST   disable a test (like pci, isapnp, cpuid, etc. )
    -enable TEST    enable a test (like pci, isapnp, cpuid, etc. )
    -quiet          don't display status
    -sanitize       sanitize output (remove sensitive information like serial numbers, etc.)
    -numeric        output numeric IDs (for PCI, USB, etc.)

最后,这个问题得到了以下代码的输出

lspci -knn | grep Net -A3; dmesg | grep iwl

这是:

02:00.0 Network controller [0280]: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe [1814:3290]
    DeviceName: Ralink RT3290LE 802.11bgn 1x1 Wi-Fi Adapter
    Subsystem: Hewlett-Packard Company Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 Combo Adapter [103c:18ec]
    Kernel driver in use: rt2800pci

第一次尝试

遵循问题,我尝试过这个:

A)

sudo service network-manager restart

这没有用,然后

b)

rfkill unblock all

但它保持硬块

第二次尝试

下列的问题 我试过我的 hp pavilion 上的无线按钮,但它唯一能做的就是打开飞行模式
